And even then, the spice isn't strictly necessary. It doesn't show THE future, it shows multiple possible futures. The navigators then take the action needed that results in a safe arrival. Computer simulation could do the same thing (if perhaps with less certainty). But, for sociopolitical and religious reasons, no computers are in use.
Dune is definitely more concerned with sociology/anthropology than physics. The physics of the shields and faster than light travel or prescience are ignored in favor of long discussions of how they affect society and how people think. There is also some discussion of biology on Arrakis. It is a plot point that some people smuggle a sandworm to another desert planet only for it to immediately starve. It is possible to transport and replicate the entire ecosystem, but not fast enough to counter the spice monopoly.
I really enjoyed the focus on social/political/religious topics. It adds so much complexity to the story Interestingly, climate change is a huge problem in the later books. The fremen dream of turning arrakis into a green paradise, but the sandworms would go extinct and society would collapse without the spice.
The Benne Gesserit realize later on in the timeline that to start the sandworm cycle on a planet you need the sandtrout first. Only when the desert reaches a certain size can the sandworm vector emerge. Oh, and the terra forming that Leto II does is with weather satellites btw.
well, if the spice gives you youth or accelerates time for your brain so it can predict the future better by having more processing power, that's literally light-speed travel in a very indirect way. brains don't need to see the future, they're literally there to predict it, the more awareness you have, aka, the more data you have, the more you will be able to actually predict the future. so it doesn't matter much if time passes slowly for you when you're basically biologically immortal and can be kept in stasis
there is a school of thought that assumes that the alien spacecraft in US posession are indeed partially powered or steered by the mind. And that for humans to be able to control them, they need a further step in evolution, implying what yogis have shown for millennia: mind over matter. This is in line with the teaching of Sri Aurobindo, who suggests that humans1.0 are not the final product of evolution. The work of Michael Levin has shown that a force of as yet unknown source powers evolution. Not just randomness. Not DNA. There are layers of determinism. Causality as suggested by Alex is the primitive current human state of consciousness. Time is an illusion. Thus is space. Everything is possible.
It is possible to predict the future. It took me a very long time to stop this. And no, it's not like seeing the newspaper in advance so you know the races or lottery. You cannot decide yourself when and what future is seen, but it is scary when it then happens in real.
A point you missed from the books, is how the Sandworm lifecycle also acts to sequester water away from the ecosystem. The Sandworms effectively de-terraform planets, instead Arraki-forming them. By causing an environmental shift, you reduce the population of Sandworms and their other forms, thereby reducing the proportion of sequestered water, which further increases water in the environment, further reducing the population of Sandworms. Eventually, you get an exponential S-curve transition back to an ocean-covered terrestrial world.
I think that's a detail easily missed because you don't learn about it until after Children of Dune. Most people stop reading the series after that part because it gets... _real weird._
@@thureintun1687 The "stupid" to look out for in fiction is cringey bad story telling. The Dune books by Frank Herbert are mostly good storytelling. Also cringey: Applying scientific paper standards to works of fiction. But that's only cringey if you don't realize it's all supposed to be for tongue in cheek fun.
The way the visions of the future are explained in the book is less "Oh I predicted the exact events that will happen" but as a sea of probabilities, with hills that block your view in some places because there are variables you don't know. Its less about prophetic visions and more about opening your mind to fully calculate everything you know to be able to see what could happen, what probably will happen, and what might happen. You aren't "seeing the future" when you lift your arms to catch a frisbee in flight, you're simply expecting that it will be in front of you in a moment. But if a dog jumps out from your blind spot and catches it instead, your prediction was wrong. Thus is the prescience that the Spice imparts in Dune. So this actually doesn't conflict with causality or information conservation.
It does allow you to see where the frisbee was thrown from even if no one was there though. Dune part two showed this by Paul talking to Fremen about his dead relative. That part mildly violates information conservation.
@@DrHooble Then it's a matter of calculating the chance of a person coming to that location to throw the frisbee in the first place. given enough initial information, we can continue predicting as far as we want even if it involves other people's actions. Afterall, if what many scientists believe is true, that free will doesn't actually exist, then it might be possible to "calculate" their choices and actions?
Well the spice imparting prescience violates causality if it imparts the effects of experience and knowledge without being exposed to information. It can certainly change the vessel we store it in and the route it gets filled. But it would still need to be filled. So if ones prescience is limited to their information exposure , even prior to being changed by the spice. Then it doesn't violate causality . Albeit I guess there is inherited knowledge .
Denis Villeneuve's Dune changes how FTL is depicted, he visualises the Heighliners as gateways whereas in the books and David Lynch's Dune, a Heighliner is a giant vessel housing thousands of passenger vessels. The Spice is used to evolve Guild navigators into mutated humans with the ability to see across space and time using prescience, which allows them to plot a safe route before the Heighliner folds space. The Spice does not create folded space, that is all done by the Holtzman Interstellar Engines which use an unknown energy source most likely Nuclear Fusion but the Spice does allow humans to use the Holtzman effect for Interstellar travel or "Travelling without moving".
thanks.,,,you saved me a bunch of typing. lol. so this is all correct. its sad that they did such a poor research job. i understand its a big universe, lots of lore. but come on, he gets so much basic stuff just wrong.
And, strictly speaking, You don't need spice to travel. It's just incredibly risky, due to collisions. You could roll the dice, You could use advanced computers (the Butlerian Jihad closed this avenue) or... You could use Spice. And as we all know, the Spice must flow. :D
That"s the problem with sci-fi tales of galactic civilizations: one has to ignore Einstein's theory of relativity for any of this fiction to make any sense. The exteme time effects of relatavistic velocities would blow up any possibility of a connected civilization. Don't even get me started on "faster than light."
But the lore is not scientifically infallible, which is only what Alex is trying to point out. Our current understanding of the universe will not align with a sci fi work that uses magic dust for space travel.
When Herbert wrote Dune, he didn't know the orbits of exoplanets. It was the 1960s. He picked Canopus, Alpha Giedi, Menkar and other bright stars because they were bright, not because any of them made sense for planets. Earth Star Trek at the time also did this. But the 'black sun' was added for the film, as the real Alpha Giedi would indeed be blindingly bright, not black. It means none of them can go outside, or have their eyeballs melted and go blind. It is also possible he was thinking of Sirius, which would be much closer, so he picked A Giedi.
@@MichaelWinter-ss6lx Not quite pure SF sicne astronomers were looking for them and there were claimed discoveries eg around Barnard's star that later turned out to be false detections but still.
Guild Navigators are navigators. They don't fold space, they allow for the guidance of the ship so it goes where they want it to. I believe Heighliners are built by Ix, a planet that is responsible for most of the advanced technology in the Dune universe.
The Guild built the original Heighliners. In later novels, however, Ix works with the Guild to retrofit them with navigation machines, as well as constructing their own No-ships.
Correct. And eventually the Ixians develop a spaceship that needs no navigator, thus the Guild is no longer anything like the power and holder of a monopoly it once was...and are in fact doomed....! Great stuff! FH RIP; Perhaps death will not part us...!
Science feeds science fiction feeds science. Martin Cooper was inspired by Star Trek’s tricorder and led the team that invented the first cell phone. Same with tablets, which were also inspired by a piece of technology from Star Trek. Earbuds were inspired by Fahrenheit 451. Virtual reality h headsets, voice activated assistants, self driving cars, the list goes on. Pondering and realizing the science behind science fiction is a noble pursuit
The Sand Worms have a larval form called a Sand Trout. They abhor water and use their bodies to sequester it. I think the idea is that besides the Fremen's underground water stores, the Sand Trouts themselves may have sequestered an ocean's worth of water deep underground. They could have released this water to transform Arrakis back into a more watery world. That would destroy spice production so no one wanted to do it.
If I were them, I would use the sand and the solar energy to make lots of glass and build large greenhouses. There they could have their lush greenery and also keep the water in them from simply evaporating. Outside of the greenhouses the sandworms could to their thing. The greenhouses could be build on the rocky outcrops, or even partly into them. The sieches already have underground dwellings, so either you build the greenhouses simply over the sieches or you make similar underground dwellings under the newly erected greenhouses.
@@johannageisel5390 I agree. It would be super easy with their technology. I think keeping the poor masses poor and miserable fits with the feudalistic theme of the Dune universe. Plus, the Harkonnens were evil slave masters so you know they wouldn't have improved the lives of the poor masses. A former Bene Gesserit with the Harkonnens had a small tropical greenhouse built for her in the royal house. They had to keep it secret I think because an audacious use of water like that would offend the desert dwelling natives.

The amount of water could never be an 'oceans' worth of water, unluess folks want to claim that their are Sandtrout bodies 3 miles thick under the sand.
Yup. Over time the waste from the sand trout mixes with the water and forms the spice and a large amount of CO2. Yes, spice is worm poo. Anyway, once the CO2 builds up enough it causes the mass of sand trout encapsulating the water to explode, spraying spice and water all over the place. The water quickly evaporates leaving behind dry spice and a few surviving sand trout that then go on to grow into sandworms. The fremen have built special devices that can condense this water out of the air, which they add to their underground cisterns.
You've missed the point of the shields, which are one of the most critical parts of the Dune universe. 1) Shields eliminate the use of all technological weapons - guns, lasguns, nukes etc etc. *You have to use knives.* 2) This creates a universe where *wars require medieval level combatants.* Their wars are fought with knives 3) This allows a feudal society to exist. "Kingdoms" with *the toughest knife fighters, from the nastiest planets, rule the universe.*
@@Orion-CSAT I've always thought the coolest thing was the Arabic influence. Until Dune, I only had science fiction with an Anglophone perspective. So Dune finally gave me a valid future universe, that wasn't a dressed up version of the UK and US in the 1950's - 1970's.
Except lasers and projectile weapons are still used, alongside swords and knives. Fighters in Dune are not medieval level, they are by necessity more versatile than any soldiers in history. And nukes also exist. There are just strict rules about their usage. Using melee weapons exclusively does not imply a feudal society. Medieval Europe used ranged weapons in combat also. And in Dune it is not warrior kings who rule. The nobility is expected to be able to defend itself from anarchists and assassins, but the best warriors are subjects of the noble houses.
@@davidwuhrer6704 Yes, but the lasgun is neutralised by the shield, because it produces a sub atomic explosion at both ends. Even artillery is available, the Harkonnens "reinvent"it for their attack. But it's ineffective against a shielded guy attacking with a knife. It's a critical component of the universe. You're correct in that a feudal society is not a consequence of weapon technology. It is a weakness of the Dune universe, that they are a feudal society. So the military of the empire e.g. the Sardaukar, is part of implicit justification of that.
@@Muritaipet Weapons technology is always a rock-paper-scissors kind of deal. Tanks don't neutralise infantry, air support does not neutralise artillery, etc. Shields and lasers can't be used together, and either may be unsuitable because of terrain anyway. But melee weapons always work. The Sardaukar are not the imperial military. They are the emperor's military. They are loyal to House Corrino, which happens to be the house on the Lion Throne, but each house has its own military. Unlike in feudalism, the emperor does not call on his vassals to go to war. There are no foreign empires to go to war against, nothing left to conquer. The wars in Dune are among the noble houses, and between the nobility and uppity peasants. And between the occasional secret societies. I don't know how you see the politics in Dune as a weakness when the authoritarian politics is the fundamental premise of Dune. The essential idea is that Fascism has won at long last, everything else logically follows, and tens of thousands of years later, long after nations as such have stopped being a thing several times over, the world is still at war, and everyone with a birthright wants to be top dog. Fanaticism breeds fanaticism. And the moral of the story is that charismatic leaders may be dangerous to your health. What did you think it was about? It's not military fiction.
Have you even read the books and the appendixed material? There are some pretty clear explanations given in the lore to all your points, from the effects of spice to shields to the Holtzmann engine on heighliner ships. Even the ecology cycle of worms, oxygen and water is very well described.
These people only talk by the movie. There are tons of details that are not in the movie but in the books. Even reading the first book would solve lots of this guy's problems
Before Chuck Yeager broke the sound barrier in 1947, people believed that breaking the sound barrier would destroy an aircraft. Some researchers even thought that it was physically impossible for an object like a car or airplane to go supersonic.
@@britishrocklovingyank3491Some of the Manhattan Project scientists were concerned an atomic bomb detonation might ignite the atmosphere. That wasn’t because they didn’t understand the fission process.
@@britishrocklovingyank3491 The point is, understanding how nuclear fission works doesn’t mean you know all the possible effects, and knowing how an airplane flies doesn’t mean you know how it’ll act at supersonic speeds. Especially when all your testing had to be done in wind tunnels, and there were no supersonic wind tunnels at the time. Do you know why many thought an airplane would be destroyed breaking the sound barrier?
magic mushrooms won't accelerate you to lightspeed, but the in-universe logic is that the hard part is not acceleration, but navigating without crashing into a star or into whatever obstacles exist in the folded warpspace or whatever medium they move through iirc.
There also exists the possibility that FTL twists your mind: warped space, hyperspace or whatever. This is used in some SciFi. Passengers get doped or otherwise go to deep sleep. The pilot or navigator must be awake and gets special dope. Some times the aliens drop out in FTL and need time to recover. One day we will discover that ganja only grows so we can stay sane in FTL.
It's less about crashing into anything and more about not getting lost in space and time. Space is big. Really, really big. You just won't believe how mind-boggingly big space is.
@@mryellow6918 Oh yes, I hate crashing into open space, and explosive gravity. All because wormholes never learned to take no for an answer and always fire all of their guns at once. Was any of that supposed to mean anything?
Yeah the whole point is that they banned thinking machines. Which means no complex machines to compute navigations. So they needed people to do that. The spice is supposed to help mutate people to be able to do that. Like the Mentats are supposed to be human computers. In the movie they downplayed this a LOT. We barely see the mentats in the movie, nor do we see any guild navigator shenanigans.
The way prescience is explained in the books and hinted at in the film, is less pure precognition and more glimpsing quantum uncertainty. Paul describes the experience in the book like gazing at a branching river or a tree, with each branch representing a possible outcome. I think what Herbert was going for was akin to being able to see how time unfolds in the events that Schrodinger's Cat was both alive or dead. Almost like the math used to calculate quantum physics made manifest.
@@Hoganply stuff like internet or vaccines also made zero sense to people barely 200 years ago. Yet here we are. Dune is set thousands of years into the future. You can only enjoy it if you suspend your disbelief for a moment and try to imagine all the possibilities that technology and knowledge will open in such a vast timelapse. If you want to stick to the things that we know for sure at the present time, these are not the novels/films for you, I suggest you move on.
@@matux6235 yes, but the shields are also kind of battery/energy-powered which means that you'll be untouchable just for a short amount of time before the energy runs out (because your using it's full power) and then your shield disappears and now instead of being 100% invulnerable you'll be 100% vulnerable from any attacks, melee or ranged 😂
As I remember it from reading all the Dune books in the 70's to 80's (my years of reading them), all water on Arrakis is sequestered by the sand worms to be used in their reproduction cycles and spice is the by-product. I think is comes in later books when Paul Atriedes and his son are the rulers.
The baby worms live in water, I believe to remember. The protective skin Leto put together, becoming a symbiont if wearing it too long. But it was found out only later, that these were the babies of the worms.
And for the science fiction books written in the 1960s, 70s, and 80s (more if you include Brian), it's very poignant and topical today with its environmental themes. Apparently, Herbert was supposed to write a piece about the Oregon Sand Dunes, which is what inspired him to write Dune. Today those dunes are degrading due to the Forest Service effort to suppress the sand dunes in the 1960s by planting European Grass. Also, the Sand Worms might or might not be a metaphor for ATVs (Oregon has a video about it on TH-cam, but I'm not brave enough to post the url)(The Terrible Purpose of social media;)
I’d just like to point out that “the spacing guild” uses spice for navigation not folding space directly. Apparently folding space is dangerous due to collisions and spice gives the navigators a level of prescience that in turn gives them a chance to “turn the steering wheel” before it’s too late kind of thing.
@@Radzood unfortunately they do not. 3rd Stage Navigators (aka Steersman) possess extended awareness allowing them to know the present conditions of space in the entire universe all at once and they possess the ancestral knowledge of how all things in space interact with each other which allows them to predict how any cosmic event will cause interactions with anything along their path allowing them to manually steer a safe course across the universe. it is a fine line between prediction and prescience but there is a line. Previous to Heretics of Dune only Paul, Leto II, and Count Fenring actually possessed any type of actual prescience, and Fenring barely had any at all.
@@MolotDET You're stuck on the 1984 movie. Lynch changed the book explanation into easy-to-digest nonsense. The ships' drives fold space, the 'gators just foresee the safest course.
FYI, if you read the books you will understand that fold space is possible without spice. The spice allows the guild stearsman to plot a safe path in fold space.
It's only a problem if the story presents it as a "rule" and is then inconsistent with it. That's how good writing works, it doesn't matter if the rules of a fictional universe are different then the real universe, what matters is if the story follows it's own rules. That's why LOTR is a well written story despite having magic, it's very internally consistent.
Which plays a part in why the Fremen are so good, since they know how to fight without shields since they attract sand worms, while the Sardaukar don’t know how to do that and are worse at it.
There are a few missing points in the video, but I’ll focus on a couple: - The shield: in the books, they described as inventions that allow slow moving particles in to allow breathing. It is not explicitly noted if that a side effect or an design choice - Planetary rotation: it was the 60s. We barely managed to put humans on the moon with the computational power of a Casio watch. I would forgive Herbert for not nailing that part, which is not really the focus of the book to begin with - Guild Navigators & Spice: Guild navigator were genetically modified humans that overused spice to be able to navigate space travel. FTL space travel was perfectly possible to achieve using machines, but “thinking” machines were explicitly forbidden after the butlerian jihad. The mechanics of spice were never explained, but I thought of it similarly to a super state of what one might thing as “in the zone”, but with numerous more data and sensory input Others have already explained the water thing. It would be fun to go over how the sand worms move, though. The most logical answer is that they “inhale” sand and “extract” it with force, like a sand jet ski.
Guild navigators were not genetically modifed. They change becouse of long abusive use of spice, litrely non-stop breath with it. That dramatcly prolong their lives and change their phisical looks, basicly body (brain and mind includs) keep developing and addapt to threir new long live and spice-base enviremant. If i remember correctly, even some of the 1st generations of navigators are alive during books events.
Regarding the force fields that block fast moving objects but allow slow ones through, I always imagined it similar to the properties of rheopectic fluids, a non-Newtonian fluid that increases in viscosity when shear stress is applied (ie the opposite of thixotropic fluids where viscosity decreases under stress. An example from grade school science is a mixture of cornstarch and water, often called “Oobleck” where you can form it into a ball in your hands but when you stop applying stress it magically oozes away through your fingers.
To clarify the association of Spice with FTL travel in the Dune Universe..... it has zero effect on the ship & its ability to move faster than light. The Spice is not used to run the FTL engines at all. The ship's FTL engines do all the work of folding space, & function completely independent of the Spice. The Spice only gives the Navigators the ability to see different possible futures... so they can predict the safest path of where to fold space & how much space to fold between jumps. Prescience is required for this, otherwise the ship might jump into an asteroid, rogue planet, or other celestial object that would destroy the ship. By consuming Spice... Navigators are able to see all these obstacles before hand, where they will be & when they will be... thus are able to navigate around those obstacles. The Spice essentially gives Navigators a mental map, by which to navigate the ship. Before the discovery of Spice... highly intelligent computers would control the ship's FTL engines to warp space & navigate starships. But there is reason why people stopped using such computers.
Dune wasn’t always a desert, the importation of sand worms made it so, as their life cycle encapsulates water. Where ever they came from they went wild on Arakis free of what ever their natural predator was. Environmental concerns were very much a theme of Herbert.
Late to the party, but this is the part that always made my brain come to a screeching halt and go "WHAT?!" Because it's said that the worms were already there when Arrakis was discovered. It wasn't until thousands of years later they realized the worms were not indigenous. So humans had nothing to do with them. Yet over 10,000 years, multiple galaxies and over 13,000 worlds later there's zero evidence of there ever being an alien civilization anywhere, let alone near Arrakis. The God Emperor never says either making one wonder if even he knew where they came from and who brought them there? If he doesn't, then the mystery of the sand worms becomes more mind boggling, because what could prevent him from knowing? The questions raised by that revelation are just insane, and it's almost entirely glossed over like "NOTHING TO SEE HERE, FOLKS!" When it's possibly THE most interesting thing in all of Dune.
I think you've missed so many details here. Like: - Arrakis was already terraformed. - Freemen are highly advanced in technology (why would not they? They are settlers from other planets - With spice, you see not "the future" but "possible futures", which is more like the ability to process more data than we can imagine but still not breaking any physical laws. - Shields need to pass slow-moving objects to allow you to breath (also part of the plot, but not for fight scenes) etc.
Which was changed in movies to use actual atomics, which in books was brought up as not possible since it would incur retaliation from other houses (if I recall). Shields also drove worms into frenzy.
@@stazeII I think you're misremembering the book. Atomics as a weapon were banned, but using them for civil engineering was OK, so Paul did a very rapid and large-scale bit of landscape redesign to create a passage for sandworms.

On the topic of needing to use pumps to keep the nano-porous membranes clean. It is explained in the books that the suits harness body movements to power various pumps around the suit. While the book only says this is used to move water from where its collected from the body to where it gets filtered and stored, it also does say that fremen suits are extremely superior to the common suits everyone else uses, and I would not be surprised if their suits doubled down on the pump pressure (making movement more difficult but they're not "soft people") to continually scrub their filters as well.
What's all this about the variable rotational speed of Arrakis? I don't recall anything about that in the Frank Herbert Dune books, except in one of them, he wrote that the planet's rotational axis was almost perfectly perpendicular, effectively not tilted at all. Maybe all this nonsense is in the Brian Herbert/Kevin J.Anderson "heresies" (😆) of prequels, sequels, pre-prequels, post-sequels, and seemingly non-stop attempts to wring as much money as possible out of Frank Herbert's sci-fi masterpiece.
Brian Herbert can't write to save his life. I read _one_ of his books over 30 years ago, & it was abominable. Can't even recall the title, but it was contrived, the names of things in the book were silly (something about a mud planet where the mud was called "galoo". Really, Brian? C'mon), & plot points were predictable. And I caught this as a 19 year old naïve kid who knew jack squat about the world.
@@DrachenGothik666 I just googled Brian Herbert's books - was it called "The Race For God?" I picked up one his books at the library one time, printed in green ink, set in the not too distant future, about a "green dictator" who will be middle-aged in the 2050s - I cannot remember the title - it was awful and I couldn't finish it. His collaboration with Kevin J. Anderson on writing the Dune prequels proved more fruitful. I remember being in Sam's Club 20 years ago, walking by "Dune: House Atreides," my eyes about popping out of my head - I glommed onto it without a 2nd thought. I will never forget its opening scene of a fit and lean Baron Harkonnen being flown around in an ornithopter watching a worm devour a spice factory.
Nah, he doesn't touch the lore too much, mostly just confirms some suspected stuff like that the Bene Gesserit were always capable of military conflict and goes with the Butlerian Jihad stuff as the ending big bad, who seems to be an inversion of the Baron. What he misses is the big alien bioprocess that makes people capable of FTL probably is doing that on purpose to spread through the universe, we didn't figure out FTL, we hitched a ride on another species in a way. I think we were supposed to get to that after we were done with The Political Effects of Time-Vision: Immortal Dictator Finally Emerges, it's just that the final book is written almost deliberately to suggest Duncan is going on an adventure, so that's what Brian wrote, Duncan's Excellent Adventures.
@@BroadwayJosh I honestly don't recall the title--I read it nearly forty years ago. I needed a book to read on a long cross-country bus ride, & I love sci-fi, so I gave the book a chance. Big mistake.
Paul Atredes and his going native does not lead to him becoming a Luke Skywalker type, as you might think, but rather, he becomes like Annakin, and then his son becomes the worm man Leto II in the sequels.
Dune is older than Star Wars. Dune was published in 1965. Star Wars was released in 1977. Star Wars copied a lot of ideas from Dune. So it would be more correct to say that Anakin becomes like Paul, except they are nothing alike. Sure, both are "chosen ones" from a young age, like Harry Potter, and both suffer from occasional future visions, but that's where the similarities end. Anakin is more like Luke: Constantly complaining, impatient, and bloody-mindedly chasing a noblewoman.
There's a lot more water on Arrakis than is made apparent in the books or movies. You need to read Children of Dune and look for the sand trout. They are a larval phase of the sandworms, and they lock up water. They go into this further in the 6th book, where they use sandworms to terraform another planet into a desert planet by introducing the sandworms. The water isn't going away, it's being locked up by the trout.
There is one other source of water on Arrakis: the north polar icecap. There are no worms there and no spice. Why don't the fremen mine ice for water there? The books hint that it is very cold there and ice mining is extremely hazardous.. And since the main draw of Arrakis is the spice, the vast majority of people simply don't go to the north pole.
In the first book ice mining was indeed mentioned. But it was done by city people - those living in areas naturally protected from Sand Worms. In those "civilized" areas Fremen are not welcomed kindly.
From my understanding from reading the second book, the future sight offered by spice follows more of a quantum model. In that you see several possible futures and can tell which ones are the most likley to occur. Basically it is about probability but not set in stone. It is difficult to change what you see as it is more unlikley to happen, but not impossible.
A whole series on Sci-Fi realism linked with current astronomic discoveries could be nice. I'd gladly watch a dissection of Star-Trek universe in relation to the actual reality of cosmos as we know it.
First thing that comes to mind is that Warp speed would be impossible. Our current understanding of physics says that any attempts at light speed or faster than light speed travel would break causality, including any sort of warp drives or even worm holes.
I think you've missed a key point about space travel from the books. Its been a little bit since I read them myself, but the concept was "Traveling, WITHOUT moving..." The notion of space folding is not that you are traveling faster than light, not in any "conventional" sense as put forth by most Sci-Fi. You aren't necessarily even "traveling through" a wormhole (although wormholes may be involved.) The idea was that you "folded" space (which was done by the highliner itself, and its Holtzman drive, not by the navigators), in effect bringing two points in the universe together "through foldspace (which is where the navigators prescience is required, to find a safe path through this "foldspace"...and as I understand it, for the SPACE BEING FOLDED...not so much the highliner itself!!) at the SAME PLACE (the highliner). You then simply ARE at the other location...there is no speed involved, not actual movement, no conventional FTL. You simply "fold" yourself through "spacetime" and are then somewhere else. Its an odd concept, but one that is theoretically supported by Einstein's relativity (i.e. Einstein-Rosen bridge, wormholes). The Navigators, saturated with melange, are capable of a limited (compared to Kwisatz Haderach anyway) form of prescience that allows them to avoid potential collisions in the foldspace, which is what made this form of space travel safe and effective and allowed travel throughout the known universe. I don't believe that the modern depiction of this space folding in the new miniseries by HBO, is actually all that accurate. The way they show the highliners is more like they are "portals", where if you look or travel through them, you arrive somewhere else. That isn't what I remember from the book...the way the book read, you had to be within the space of the highliner when space was folded in order to "travel" and if you were not within that space, then you didn't travel. The Dune miniseries from 2000 seemed to depict this more accurately, and I guess so did the original Dune from 1984...I've been disappointed in the relatively cheap effects and approach to this form of space travel that the newer movies have taken. It seems like a copout, to avoid even trying to depict how this form of travel might look like. -\_o.o_/-
You are right about how the folding space works. I think Villenuve made a mistake depicting the Highliner as he chose to. But it is a far out concept to visually depict. As those inside see nothing and the ship just dissappears and reappears. Even Herbert doesn't 'show' it. He just info dumps it on the reader as Paul's inner monologue. I think the idea was to show the ship existing at both points in spacetime at once, but it doesn’t come across unless you're already familiar with how it's meant to work from the books. Strangely enough, Star Wars (Dune's bastard child) depicts FTL via wormhole pretty well.
That's what a wormhole looks like: You enter at one end where it's invisible, and exit at the other end, where you see the entrance. Entrance and exit are the same volume in spacetime, but traversal is unidirectional. The heighliners create that wormhole by folding space. They have to be at both ends for that, naturally. In the book, Paul never sees a heighliner. He enters a shuttle, and an unsolicited time later he exits a shuttle. Maybe the same shuttle. Compartments aboard the heighliner are mentioned, but not what they are.
In the books, the holtzman field is created by a holtzman generator... which frequently overheats when heavily taxed by incoming projectiles. Presumably the impacts against the shield are feeding back into the generator. Another interesting detail from the books is that the shields react explosively when hit with lasers... a fact that was not known until the shields were already heavily deployed among military personnel (turns out, lasers were an ancient weapon that wasn't very effective due to energy requirements) Someone ends up firing an old museum relic at Theo Holzman himself (the named inventor, but not the actual inventor), who was wearing a shield, and it destroys an entire city. The physics of that reaction are also not covered in the books (where does the energy come from for an explosion the size of a nuke, when the interaction was caused by a battery powered laser and a battery powered shield generator?) About the water on Dune: the water was always on the planet, but it was tied up by creatures called "Sand Trout". These creatures aggressively find water and absorb/trap it under ground. The sand trout are the larval stage of the sand worm. Once the water is trapped, some sand trout become Shaitan (Later called Shai Hulud). Sand worms cannot live in the presence of water. The terraformers eventually realized that destroying the sand trout would release the waters, which would destroy the worms, allowing water to flow on Arrakis... though even after this was done, there wasn't enough water to have full-blown oceans on the planet... but rivers on the surface did exist.
It's both. Concentrated spice essence is blue. Hense the blue within blue Eyes of Ibad of Fremen and spice addicts. The mature spice becomes redish after it erupts from deep beneath the sand; it's then oxidized and dessicated by Arakkis's intense sunlight and dry atmosphere. It's at that stage it's granular, redish, and smells vaguely of cinnamon.
Spice isn't blue, the cisterns aren't wells but the collected water of generations and the terraforming of Arakis is done by billions of people from across the galaxy making pilgrimages to Arakis to pay homage and leaving behind water vapor from breathing and all the other ways people lose water.
It's both. Normal spice harvested from the sand is redish orange due to oxidation and drying under Arakkis's sun. _Very_ concentrated spice essence like the Water of Life or Sapho, used by Mentants, was blue.
@@melissaharris3389 The water of life was bile from new born sand worms I kinda thought it was its own thing yes similar but diffrent and I dont think sapho was spice or derived from spice at all but i could be wrong
As a soon to be designer of electric aircraft, and only 1:35 into the video, looking forward to your analysis of the 'ornithopters', although they are not in fact bird like, but giant dragonflies. In reality, on Earth anyway, these flying machines would explode into pieces of mechanical parts on power up if such huge wings flapped that fast against the soup of terrestrial Terran air.
i wonder if the shields would come in handy here...? like the craft itself is protected by the shield and the strong forces just make sure that no energy is passed onto the frame? of course, when we see how they operate, the crafts should glow highly blue when they are active then, i guess.
Dragonflyesque indeed. However it also reminds me of a hummingbird's flight technique. Large proportional wings, like you said, would be absurd. But perhaps you could think about a vehicle with tens of thousands of tiny mechanical hummingbird wings. Would that work?
Not exactly, look up the youtube video "I built a simulated ornithopter and the results surprised me", it would be more viable than people think, even on earth. (And the gravity on arrakis is lower than earths, regardless of what some of the wiki information says, the planet is quite a bit smaller than earth due to the time it takes for characters to travel across the surface, based on speed)
It doesn’t make sense to terraform Arrakis in its entirety. The entire value of the planet is in its spice, which as we know is deeply tied in with the sand worms. If they terraform the entire planet, it would mean the extinction of sand worms, and no sand worm=no spice and no water of life(Arrakis Whiskey). They’d just make themselves a backwater planet and worse, it would mean that interstellar travel will no longer be possible, leading to the collapse of the galactic civilisation.
I kind of feel like the title is clickbait, either that or there is a lack of understanding about how things work in Dune. Yes Frank Herbert clearly didn't care much or study much about astronomy. Yes, quite a bit of the technology in Dune hasn't been discovered. But you have to remember that Frank Herbert wrote Dune in 1965. The first exoplanet wasn't discovered until 1992. Astronomy in Dune is actually quite a bit better than even science fiction books that came out after 1965. Original Star Trek is far more inaccurate and the original series came out in 1966, and I'd argue that even what is being created recently is less accurate than Dune. Star Gate is also highly inaccurate, the very idea of using constellations is ridiculous from a scientific standpoint. Most of the constellations we see in the sky would make absolutely no sense if seen from even a slightly different angle. Basically almost every science fiction show and movie is probably as bad or worse than Dune. Then you have the technology. The faster than light travel is highly dangerous in Dune, it's like traveling through chaos in Warhammer 40k without the demons but with far more likely chances of being destroyed. Space Navigators basically see into possible futures using spice, but in a very specific way. Basically it let's them pick the best parameters which changes the exact travel path and avoid being destroyed. Without this nearly all ships traveling faster than light would be destroyed. This also isn't exactly the same as seeing into the future. It's like taking a drug that increases your predictive abilities and ability to infer the future. So imagine that you have some type of sonar and you need to navigate a lake that is filled with icebergs, without hitting any icebergs. Predicting exactly where the icebergs would be is almost impossible, just figuring out where they are from sonar would be difficult. But taking spice increases your brains ability to compute all of this and figure out where the icebergs will be as you travel past them. This can actually be done using computers, I think in one of the prequel books that Frank Herberts son wrote they used computers and ended up with only around a 10% destruction rate for ships traveling faster than light, and this likely could have been improved over time. Space navigators still screw up sometimes, and they are very much in demand because it's not something that all humans can do well. Kind of like how the best ATF controllers almost always imagine the location of things in 3d, whereas most people only think of maps of a building or area in 2d. I don't see how any of this is less scientific than say a warp drive in Star Trek? For shields I get that having a shield itself doesn't seem likely. But you see shields in a number of other science fiction shows. It being modulated to let slow things through makes some sense due to needing to breathe and that you want to be able to touch objects and also walk around. If it blocked everything you wouldn't be able to touch the ground, pick up a weapon or ammunition that was outside the shield, and you would need your own source of air inside the shield. There is also an interaction where high energy weapons will cause an explosion when they hit a shield. So combat basically is done with knives and various ballistic weapons, but mostly knives at close range that can go just slow enough to get inside of the shields. It's actually a part of the books that the movies screwed up. When Paul was fighting the first time he had trouble killing his opponent which the movies showed, but it mostly wasn't because he was hesitant to kill someone, it was because he was trained to fight someone that had a shield. When fighting an opponent in a shield you can use your full speed to dodge their attacks, but when you attack them you have to do it slowly so that you can get through their shield. Seriously I think that the teleporter in Star Trek is far less believable. Also the sandworms do rely on water to survive. The life cycle of a sandworm is kind of odd. Basically they aren't one creature, they are actually a kind of hive of what are called sand trout. If exposed to too much water a sandworm will "die" and turn back into sand trout. Groups of sand trout absorb and almost kind of lock water away from the rest of the environment. Imagine a layer of sand trout that is absorbing water just above the water table, but across an entire desert planet. They release spice as a byproduct. And they eventually merge and become sand worms which then live in the drier area above the water table. Then the sandworms die and create more sand trout. Basically you put sand trout on a planet and they will slowly transform it into a desert world. If you want to reverse the process you just have to kill all the sand trout, the water will be released and kill the sand worms, then you kill the sand trout that were released when the sand worms died. So they get plenty of water when they are sand trout, and they continue to get a small amount from what they eat. Likely if they don't get enough they just break back apart into sand trout, or if they get too much they break apart because the sand trout start feeding on the water instead of maintaining the connection as a sand worm. Yes it's an odd creature, but I don't think it's that much odder than many other creatures in other science fiction.
By precognition I always assumed that it's a future prediction by extrapolating the current state of the universe, not some baked-in future, so it can change for sure. Paul and other future kwisatz Haderach has to actively act to shape the future. No paradoxes. Anyways, I like the Dune universe a lot, though most elements of it are there just to get the plot going. It's not a bad thing because it's pretty well worked out, but it definitely places Dune much more into the fiction/fantasy category for me.
Yes. I think the second part made some odd choices, but the first was just awesome. For example, Margo Fenring. I assumed that she would just pretend to be one of Feyd's groupies, not how they depicted it in the film. Or the surface of Giedi, I would have assumed life on that industrial planet to be basically all underground. And why they didn't use that effect for the nuclear explosion instead. But the interaction between Feyd and the Beast was great. The emperor came across as borderline senile though. His Sardaukar are religious fanatics, he is their living god, he is supposed to be terrifying, in a Christopher Walken kind of way. Anyway, the end was a great payoff, even though it deviated from the book.
@@GodOfWar05100 I understand that one. On film you need things to be apparent by just seeing it. It would feel forced to have a line of dialogue say that "by the way this emperor guy is like 70 years old even though he looks young".
Sorry if someone mentioned this already, but the force fields could stop everything from entering it, but if you set it to do that it would also block fresh air, so for personal shields you have to let slower stuff in to be able to breath. Spaceships on the other hand would normally turn them on to the max.
8:00 Force Fields = the reason those personal shields in Dune don't make scientific sense is because the author was using them as a narrative device (foreshadowing) _"slow blade penetrates the shield"_ is actually a metaphor for the subtle treachery associated with the nobility
One thing, Alex, you didn't even touch on, is where does the planet get all of its oxygen from in the first place? Zero greenery to speak of, no oceans for plankton, and absolutely nothing for photosynthesis. What on that planet produces oxygen? Never mind an atmosphere very Earth-like. That's always been my biggest question.
@@vileluca yeah, I know about that plankton. Of course I take issue with that as well. Plankton require water to survive too and on the surface in the sand where they live is dry as well. At any rate, thanks for the reply.
Dune was once a lush jungle planet and the remains of the desiccating plants buried under the sand produce gasses which are processed by the sand plankton and produce o2.
The one scientific necessity ignored or not realized in the creation of harsh desert planets such as Arrakas or Tatooine is the basic biological principle of an oxygen cycle. Oxygen is extremely reactive and must have a mechanism such as photosynthesis found in plant life to make it available to breathe or it will quickly react to most all but a small handful of the other elements.
Not sure about Tatooine, but on Dune oxygen is created by the sand plankton's interaction with the desiccating remains of the ancient jungles which existed on Arrakis before the sand trout were introduced. Plant biomass buried under the sand releases gases which are processed by the sand plankton and turned into oxygen.
@@MolotDET Thanks for taking the time to explain that, but it still seems like a stretch. Of course giant worms that can move at 80 miles an hour through sand are also a bit of a stretch... :)
The shields use/issue is twofold: first, slow moving objects (like oxygen and CO2 exchange would have to take place so that the wearer didn’t suffocate). Second, the slow moving objects getting through were designed to show the limitations of technology.
Dune was originally a lush and verdant planet. The Sand Trout and sandworms turned it into a desert. It was already that way before humans arrived. Only Frank Herbert knows where the sandworms came from. They're not native to Dune. Some other comment said that Sandworms were smuggled to other planets but didn't survive. I think they should have smuggled Sand trout instead. But the characters in the book don't fully understand the life cycle of the Sandworms and the attempts were doomed to fail. Bless the maker and his water.
Spice doesnt make things go the speed of light. It allows the space navigators make the necessary calculations to safely travel through space. Its needed because thinking computers are banned in dune
the stated explanation of faster than light constraints here, does not apply to (theoretical) space folding to effectively achieve faster than light travel. warp drives do not violate known laws of physics. neither does quantum teleportation. the speed of light only restricts how objects with mass move through relativistic space, not how space may be compressed.
Spice isn't blue. The shields allow things generally moving slower than 6 cm per second to pass through so that air can pass through so the user can breathe also so that they can handle objects like their swords
The melange ESSENCE is a blue LIQUID. Spice powder is never described as blue. It is described as "glowing blue," in God Emperor of Dune, and the gaseous form is orange. "Glowing blue" could indicate a phosphorescent glow, and not necessarily refer to the base color of the material. I am currently rereading the Frank Herbert Dune novels. I am on Heretics of Dune, and so far that's about all of the descriptors used. The textiles made from "spice fiber" are described as red, and taken all together, I imagined the spice to be deep reddish brown with a blue phosphorescence. I know some are adamant that the spice is blue, but Frank Herbert consulted on the original movie, and it was cinnamon colored there. If he considered the melange to be blue, especially considering how rare blue tends to be in nature AND how often he used other color descriptions for other aspects of spice and spice products, I think it would have been blue in the original movie.
I was hoping to see the lasgun/body shield interaction in the first movie, as mentioned in the book. It'll be interesting to see how they render the stone burner explosion in Dune Messiah. I have an old paperback copy of the Dune Encyclopedia, which was considered cannon until the prequel books came out.
The space guild doesn’t necessarily see into the future as much as they use the spice to make the calculations. There are no computers because of the past war. The navigators of the space guild are basically human supercomputers. They also are not the same as normal humans.
The larva state of the sandworm actually seeks out water and stores it, And actually the planet aracquest was terreformed by the sandworm larva because it was Found that the larva did not originate on dune. there's an encyclopedia
I think the reason the shield is able to counter such high velocity objects but not low velocity is because it’s really efficient at using the force and kinetic energy from the object to push back on the object itself. So the harder and faster the projectile pushes the shield the more force is applied back to the bullet. Of course it would make sense if there’s a threshold, too much force over too much time can break the shield while too little force could not generate enough energy to push back on the projectile.
I love your videos but I find this to be a rather shallow and clickbaity attempt to jump on the current Dune bandwagon. We know it's science fiction, it's implied that some of the technologies used are fictitious to us, either because they are too advanced for our current understanding (you didn't mention that the story happens over 10,000 years into our future, it's pointless to compare their technology with our current one), or because they are just made up to suit the story. You don't need to claim that Herbert "got it ALL wrong" (as per the clickbait video title you used) because this is not a science paper we are analysing, it's a fiction universe. I also got the feeling that you have based your whole analysis on a rather shallow watch of the current films and some wiki reading, but you missed some key ideas of the original novels, such as the real use of the spice or the complex implications of the sandworms. I think you do great science videos and I'll keep watching them with pleasure, but your strictly scientific approach is not the best to analyse fantasy settings like this one. My comment was attempted as constructive criticism, I hope I don't sound too grumpy haha. Cheers!
The impression that I got from the book and the movies is that Spice doesn't allow one to see the future. Instead, it increases one's perception and calculative ability to the point that they can deduce possible futures and pick the ideal outcome. The book also mentions a subtle communal empathic connection the Fremen share due to their constant spice exposure, which may be a result of the increased sensory information. The book does have a chapter going over the terraforming process for Arakis, which described a fairly plausible cultivation of fundamental systems until they could be come self sustaining and allow for more complex layers to be built on. The movies trim a lot of the specifics in favor of narrative clarity (in addition to some tasteful rewrites), but the book gets pretty particular about a lot of the theory. I haven't read past the first book, so I can't speak to how they develop.
One point. The guild mastered faster then light travel, but anyone can do it. It’s dangerous. The spice gives some humans the ability to see the safe path. The spice does nothing to make it possible only possible to see the safe path.
Considering how it's impossible to pull yourself out when you're half-buried in sand, I'd like to see a serious calculation of how much power a sandworm needs to propel itself through the sand at speed a couple of hundred meters deep. And how many calories they'd need to get that much energy.
Eh, it is a solved problem. Specifically, by Tremors back in 1990. They work like a combination of snake and fish, with little fins that act like sand-oars.
Dune is as much about science and technology as it is about geopolitics, history, colonisation, ecology and psychology. Note: Replace spice with fossil fuels and magic shrooms and you get the connections to Earth colonial history and geopolitics.
The shields could have some form of antigravity effect, but the science doesnt seem to back up that antigravity exists. It could be a non-newtonian liquid effect but with particles. That would explain why the slow blade penetrates the shield.
My understanding of how the Heighliners work (at least in the current DV films) is that they aren't like stargates where you'd need one above every planet and link them. They're ships; they gotta move. But the way they move is via spice which bends spacetime. When a Heighliner is active it exists in two spaces at the same time. This is why you can see through them into other star systems
The spice does NOT bend space. The Holtzman engine in the ship does. The navigator uses spice to 'see' a safe path to the destination. The engine creates the path of the wormhole that was ploted by the navigator. Then space is instantly folded around the ship to "move without moving".
The shields always felt real to me. Like when you slap water, it seems hard, but if you touch it slowly you can push into it. Most real life a science 'rhymes' like this. The ships in Dune don't really move FTL. They travel without moving. They make the two points in space the same. The effect in the film is a departure from the book. Dune 84 got it better. Physics today can't really explain distance or the difference between 2 points in space.
Exactly. The Heighliner is in orbit above planet A, the Navigator chooses the route (though probably not using beams of light from his mouth), the Holtzman drive folds space so planet B is for all purposes directly adjacent to Planet A, and when the drive shuts off the Heighliner is in orbit above planet B. From a frame of reference outside the universe it was the universe that moved, not the Heighliner.
No, Lynch didn't get it better. His film has very little to do with the book and gets pretty much everything wrong. It's a very different film. Physics _can_ and _does_ explain distance: First, accept that the speed of light is a constant. Distance, then, is a function of the time it takes for events at one point to affect the other. (So simple that most people can't wrap their head around it.)
It's called Sci-Fanstasy or soft sci-fi. Star wars could be considered Sci-fantasy, Dune as soft-scfi and Foundation as hard sci-fi (being that it is based on mathematical sociology). Like fantasy, there are many sub genres within sci-fi. Dune is sci-fi, just not hard, though harder than star wars. Star Trek is all of the above depending on the episode. Though there are many distinctions between these sub-genres, remember that politics and international relations are sciences. The points between certain fantasy books and soft sci-fi can become blurred if both discuss socio-political issues that relate to our conceptions of said subject. Usually one chooses the theme of magic where as the other chooses technology. Furthermore, one chooses a fictional past, the other a future. Though, again, this isn't always the case.
I agree with the original comment. Even by soft sci-fi standards, it comes up short. Don't get me wrong, it's a fantastically rich tale, with many fascinating concepts and intriguing thoughts on the human condition. But even Herbert himself said the science is only tangential to the plot.
@@GoldenMinotaur Not really, but I do think science fiction as a genre is based on the exploration of scientific concepts. Dune doesn’t go in depth into anything scientific, what it does go into is only in service of its themes and narrative. Why I think it’s more closely related to fantasy though is because it hits on almost every traditional epic fantasy trope, except it deconstructs and criticizes them.
@@wlot28 I respect that. To me science fiction has always been a vessel to convey controversial or sensitive concepts to a reader that might disconnect from an ego response if they feel too connected to the antagonistic aspects. But that's the beauty of books, we each own our own experience, not even the author supercedes our interpretations
Read the book and you’ll see there are artificial satellites orbiting Arrakis. The Fremen bribe the Spacing Guild with spice to avoid certain areas where they’re doing things they don’t want seen by the Harkonnens or Empire.
In the first book it was mentioned that Fremen pay exorbitant bribe in Spice to Trading Guild to specifically NOT notice any curious things happening in the desert.
16:20 "Crawford's gray shrew" or commonly known as "Desert Shrews" are known to sustain themselves entirely from prey, being able to survive without any additional water.
I would think any sort of machinery in a sand environment has to be a nightmare for the people who have to maintain the equipment. Good for the filter business I suppose though.
They need flying machines to get anywhere quickly, and it sort of makes sense that future flying machines resemble naturally evolved designs. The indigenous people know better than to use flying machines, but the off-worlders would be used to them (and labour is cheap anyway), and can't be expected to learn how to ride on the local fauna.
Yeah nothing makes sense when it comes to food, there are millions of Fremen living in the deep desert and there is nothing to eat. You can't grow or hunt enough food to sustain such a huge population with the storms. Unlesss you have massive giant underground hydroponics but that would take a ton of water and they keep losing water in various ways when they go out. The water is very expensive so they also can't go to the villages and buy it. So many survival stories lack the food aspect, that we can't survive on a few tomatoes in asoup, we need 2000 calories a day at the very least if you are doing any sort of physical labour. Knife fighting in the heat? 3000. Galons of water. Frank Herbert describes how the Fremen have dry bodies, skinny from lack of water in their tissues, blood barely drops. If a human lived like that he'd be dead.
The books describe parts of the ecology. Herbert was particularly interested in that aspect. The Fremen use wind traps to extract water and energy from the air. There are also mice and bats living in the desert. And sand trouts are also a source of water.
It is by will alone I set my mind in motion. It is by the juice is sapho that thoughts aquire speed. Thoughts aquire speed and lips aquire stains, the stains become a warning. It is by will alone I set my mind in motion.
Spice doesn't cause "actual" prescience, so to speak. It just makes you really, REALLY good at making distant predictions from limited information. So you see the future as a sort of probability field. But no new information is being transferred.
We need to practice hand to hand combat incase the enemy is wearing a shield that can only be penetrated by epic, sexy, well choreographed knife attacks.
It’s amazing this was written so long ago in the 60’s, some of the concepts are so modern and timeless, it’s not aged in a way like a lot of bad sci-fi from decades ago where the ‘future’ versions of concepts from the time just seems dated and silly today
On the topic of needing to import water from other planets. That's actually been happening as of the books. Its one of the ecology mysteries on Dune that is explained when Paul meets the Fremen. The Harkonens and later the Attreidies import huge amounts of water every month to keep their coffers full and keep their palace comfortable and livable. This water regularly was lost, the noble families weren't much for conservation when they were so wealthy. At one point someone (I forget who) questions where the water is going, I mean, how much water can the atmosphere evaporate before the air starts to get a little less dry. It has to be going somewhere. The cisterns that the fremen keep aren't just people's body water like it seems to imply in the movies (as that would just slowly decrease the amount of people that could live on Arakis, since that water is needed for life). The water nets they use to catch water vapor from the wind and other techniques are the Fremen constantly harvesting, all day every day, across the planet, the water that is imported by the noble houses, and then lost to evaporation. They were already preparing for the beginning of the terraforming with offworld water.
Also, most of the planets water is locked deep beneath the sand by Sand Trout (the larval stage of the sandworms). The very act of sequestering the water is what eventually creates spice.
Has anyone ever wondered why they dont just stick an icey asteroid or comet in orbit around arakis with their obviously exceedingly advanced space travel technology, and then just...mine it for any water needed by the human population? You dont NEED to destroy the sandworm habitat if you just...keep the water away from them, in the human-habitated areas. Or has someone already gone over this concept?
It is mentioned in the books that water is mined from Arakkis's northern poler icecap and imported (at great cost) from off world by the Arraken: the people that live in the cities and are mostly decendents of off worlders from the Imperium. The Fremen live exclusively off the dessert in their traditional way.
Thanks for 19:05 allowing Dune to be more like cool story and less like scientificaly acurate. Might SciFi films should have a rating on "more like on the beeing science acurate side" versus "more at the making the story as cool as posible, even if it violates science" part.

The spice doesn't make the faster than light travel possible, it makes it navigable.
And even then, the spice isn't strictly necessary. It doesn't show THE future, it shows multiple possible futures. The navigators then take the action needed that results in a safe arrival.
Computer simulation could do the same thing (if perhaps with less certainty). But, for sociopolitical and religious reasons, no computers are in use.

Dune is definitely more concerned with sociology/anthropology than physics. The physics of the shields and faster than light travel or prescience are ignored in favor of long discussions of how they affect society and how people think.
There is also some discussion of biology on Arrakis. It is a plot point that some people smuggle a sandworm to another desert planet only for it to immediately starve. It is possible to transport and replicate the entire ecosystem, but not fast enough to counter the spice monopoly.
I really enjoyed the focus on social/political/religious topics. It adds so much complexity to the story
Interestingly, climate change is a huge problem in the later books. The fremen dream of turning arrakis into a green paradise, but the sandworms would go extinct and society would collapse without the spice.
Exactly I always said Herbert at heart was an anthropologist
@@alexsdarkclubband 20 thousand years in the future there would probably be a way to synthesize the substance.
The Benne Gesserit realize later on in the timeline that to start the sandworm cycle on a planet you need the sandtrout first. Only when the desert reaches a certain size can the sandworm vector emerge. Oh, and the terra forming that Leto II does is with weather satellites btw.
You don't travel faster than light.
Only space can do that
I disagree. Eating a Magic Mushroom on a spaceship can lead to lightspeed travel... for the user.
.....I concur.
Time is relative after all. And since speed depends on time, speed must be relative too. So indeed the user could be experiencing lightspeed.
well, if the spice gives you youth or accelerates time for your brain so it can predict the future better by having more processing power, that's literally light-speed travel in a very indirect way.
brains don't need to see the future, they're literally there to predict it, the more awareness you have, aka, the more data you have, the more you will be able to actually predict the future.
so it doesn't matter much if time passes slowly for you when you're basically biologically immortal and can be kept in stasis
there is a school of thought that assumes that the alien spacecraft in US posession are indeed partially powered or steered by the mind. And that for humans to be able to control them, they need a further step in evolution, implying what yogis have shown for millennia: mind over matter. This is in line with the teaching of Sri Aurobindo, who suggests that humans1.0 are not the final product of evolution. The work of Michael Levin has shown that a force of as yet unknown source powers evolution. Not just randomness. Not DNA. There are layers of determinism. Causality as suggested by Alex is the primitive current human state of consciousness. Time is an illusion. Thus is space. Everything is possible.
It is possible to predict the future. It took me a very long time to stop this. And no, it's not like seeing the newspaper in advance so you know the races or lottery. You cannot decide yourself when and what future is seen, but it is scary when it then happens in real.
A point you missed from the books, is how the Sandworm lifecycle also acts to sequester water away from the ecosystem. The Sandworms effectively de-terraform planets, instead Arraki-forming them. By causing an environmental shift, you reduce the population of Sandworms and their other forms, thereby reducing the proportion of sequestered water, which further increases water in the environment, further reducing the population of Sandworms. Eventually, you get an exponential S-curve transition back to an ocean-covered terrestrial world.
I think that's a detail easily missed because you don't learn about it until after Children of Dune. Most people stop reading the series after that part because it gets... _real weird._

stupid stuff 😂
So stupid. No wonder it is a science " *FICTION* " , not scientific peer reviewed research paper😅
@@thureintun1687 The "stupid" to look out for in fiction is cringey bad story telling. The Dune books by Frank Herbert are mostly good storytelling. Also cringey: Applying scientific paper standards to works of fiction. But that's only cringey if you don't realize it's all supposed to be for tongue in cheek fun.
The way the visions of the future are explained in the book is less "Oh I predicted the exact events that will happen" but as a sea of probabilities, with hills that block your view in some places because there are variables you don't know. Its less about prophetic visions and more about opening your mind to fully calculate everything you know to be able to see what could happen, what probably will happen, and what might happen.
You aren't "seeing the future" when you lift your arms to catch a frisbee in flight, you're simply expecting that it will be in front of you in a moment. But if a dog jumps out from your blind spot and catches it instead, your prediction was wrong. Thus is the prescience that the Spice imparts in Dune. So this actually doesn't conflict with causality or information conservation.
It does allow you to see where the frisbee was thrown from even if no one was there though. Dune part two showed this by Paul talking to Fremen about his dead relative. That part mildly violates information conservation.
@@DrHooble Then it's a matter of calculating the chance of a person coming to that location to throw the frisbee in the first place. given enough initial information, we can continue predicting as far as we want even if it involves other people's actions. Afterall, if what many scientists believe is true, that free will doesn't actually exist, then it might be possible to "calculate" their choices and actions?
Well the spice imparting prescience violates causality if it imparts the effects of experience and knowledge without being exposed to information.
It can certainly change the vessel we store it in and the route it gets filled.
But it would still need to be filled.
So if ones prescience is limited to their information exposure , even prior to being changed by the spice. Then it doesn't violate causality .
Albeit I guess there is inherited knowledge .
@@DrHooble Paul had just consumed the water of life that contained all the collective memory of the fremen
@@DrHooblehe knows about dead relatives because he has the memories of thousands and thousands of people in his mind
Denis Villeneuve's Dune changes how FTL is depicted, he visualises the Heighliners as gateways whereas in the books and David Lynch's Dune, a Heighliner is a giant vessel housing thousands of passenger vessels. The Spice is used to evolve Guild navigators into mutated humans with the ability to see across space and time using prescience, which allows them to plot a safe route before the Heighliner folds space. The Spice does not create folded space, that is all done by the Holtzman Interstellar Engines which use an unknown energy source most likely Nuclear Fusion but the Spice does allow humans to use the Holtzman effect for Interstellar travel or "Travelling without moving".

Very good. You just revealed why this video made me feel so strange. And reminded me why I always prefer reading the book over watching a film.

Nice, this makes sense
And, strictly speaking, You don't need spice to travel. It's just incredibly risky, due to collisions. You could roll the dice, You could use advanced computers (the Butlerian Jihad closed this avenue) or... You could use Spice.
And as we all know, the Spice must flow. :D
That"s the problem with sci-fi tales of galactic civilizations: one has to ignore Einstein's theory of relativity for any of this fiction to make any sense. The exteme time effects of relatavistic velocities would blow up any possibility of a connected civilization. Don't even get me started on "faster than light."
The lore is very clear about why the shield allows slow moving things through. It’s so air can pass and so you can interact with objects
so it's by intelligent design rather than an inherent property of the field?
@@lu-uf8zj Exactly
@@lu-uf8zjthe feild has been tuned by intelligent design
If that was the case, why not strap on an oxygen tank, crank up the shield, and make yourself invincible.
But the lore is not scientifically infallible, which is only what Alex is trying to point out. Our current understanding of the universe will not align with a sci fi work that uses magic dust for space travel.
When Herbert wrote Dune, he didn't know the orbits of exoplanets. It was the 1960s. He picked Canopus, Alpha Giedi, Menkar and other bright stars because they were bright, not because any of them made sense for planets. Earth Star Trek at the time also did this.
But the 'black sun' was added for the film, as the real Alpha Giedi would indeed be blindingly bright, not black. It means none of them can go outside, or have their eyeballs melted and go blind.
It is also possible he was thinking of Sirius, which would be much closer, so he picked A Giedi.
Eyes melt; skin explodes; everybody dead!
Also, it's science "FICTION" for a reason...
Exoplanets in the 1960s was pure science fiction.
Either way, the thermal camera technique they used for Dune: Part 2 was incredible.
@@MichaelWinter-ss6lx Not quite pure SF sicne astronomers were looking for them and there were claimed discoveries eg around Barnard's star that later turned out to be false detections but still.
Guild Navigators are navigators. They don't fold space, they allow for the guidance of the ship so it goes where they want it to. I believe Heighliners are built by Ix, a planet that is responsible for most of the advanced technology in the Dune universe.
many machines on Ix, new machines, better than those on Richese
The Guild built the original Heighliners. In later novels, however, Ix works with the Guild to retrofit them with navigation machines, as well as constructing their own No-ships.
Correct. And eventually the Ixians develop a spaceship that needs no navigator, thus the Guild is no longer anything like the power and holder of a monopoly it once was...and are in fact doomed....! Great stuff! FH RIP; Perhaps death will not part us...!

Science feeds science fiction feeds science. Martin Cooper was inspired by Star Trek’s tricorder and led the team that invented the first cell phone. Same with tablets, which were also inspired by a piece of technology from Star Trek. Earbuds were inspired by Fahrenheit 451. Virtual reality h headsets, voice activated assistants, self driving cars, the list goes on. Pondering and realizing the science behind science fiction is a noble pursuit
The Sand Worms have a larval form called a Sand Trout. They abhor water and use their bodies to sequester it. I think the idea is that besides the Fremen's underground water stores, the Sand Trouts themselves may have sequestered an ocean's worth of water deep underground. They could have released this water to transform Arrakis back into a more watery world. That would destroy spice production so no one wanted to do it.
If I were them, I would use the sand and the solar energy to make lots of glass and build large greenhouses.
There they could have their lush greenery and also keep the water in them from simply evaporating. Outside of the greenhouses the sandworms could to their thing.
The greenhouses could be build on the rocky outcrops, or even partly into them. The sieches already have underground dwellings, so either you build the greenhouses simply over the sieches or you make similar underground dwellings under the newly erected greenhouses.
@@johannageisel5390 I agree. It would be super easy with their technology. I think keeping the poor masses poor and miserable fits with the feudalistic theme of the Dune universe. Plus, the Harkonnens were evil slave masters so you know they wouldn't have improved the lives of the poor masses. A former Bene Gesserit with the Harkonnens had a small tropical greenhouse built for her in the royal house. They had to keep it secret I think because an audacious use of water like that would offend the desert dwelling natives.

The amount of water could never be an 'oceans' worth of water, unluess folks want to claim that their are Sandtrout bodies 3 miles thick under the sand.
Yup. Over time the waste from the sand trout mixes with the water and forms the spice and a large amount of CO2. Yes, spice is worm poo. Anyway, once the CO2 builds up enough it causes the mass of sand trout encapsulating the water to explode, spraying spice and water all over the place. The water quickly evaporates leaving behind dry spice and a few surviving sand trout that then go on to grow into sandworms. The fremen have built special devices that can condense this water out of the air, which they add to their underground cisterns.
You've missed the point of the shields, which are one of the most critical parts of the Dune universe.
1) Shields eliminate the use of all technological weapons - guns, lasguns, nukes etc etc. *You have to use knives.*
2) This creates a universe where *wars require medieval level combatants.* Their wars are fought with knives
3) This allows a feudal society to exist. "Kingdoms" with *the toughest knife fighters, from the nastiest planets, rule the universe.*
Which, coincidentally, makes it much much cooler.
@@Orion-CSAT I've always thought the coolest thing was the Arabic influence. Until Dune, I only had science fiction with an Anglophone perspective.
So Dune finally gave me a valid future universe, that wasn't a dressed up version of the UK and US in the 1950's - 1970's.
Except lasers and projectile weapons are still used, alongside swords and knives. Fighters in Dune are not medieval level, they are by necessity more versatile than any soldiers in history.
And nukes also exist. There are just strict rules about their usage.
Using melee weapons exclusively does not imply a feudal society. Medieval Europe used ranged weapons in combat also. And in Dune it is not warrior kings who rule. The nobility is expected to be able to defend itself from anarchists and assassins, but the best warriors are subjects of the noble houses.
@@davidwuhrer6704 Yes, but the lasgun is neutralised by the shield, because it produces a sub atomic explosion at both ends. Even artillery is available, the Harkonnens "reinvent"it for their attack. But it's ineffective against a shielded guy attacking with a knife. It's a critical component of the universe.
You're correct in that a feudal society is not a consequence of weapon technology. It is a weakness of the Dune universe, that they are a feudal society. So the military of the empire e.g. the Sardaukar, is part of implicit justification of that.
@@Muritaipet Weapons technology is always a rock-paper-scissors kind of deal. Tanks don't neutralise infantry, air support does not neutralise artillery, etc.
Shields and lasers can't be used together, and either may be unsuitable because of terrain anyway. But melee weapons always work.
The Sardaukar are not the imperial military. They are the emperor's military. They are loyal to House Corrino, which happens to be the house on the Lion Throne, but each house has its own military.
Unlike in feudalism, the emperor does not call on his vassals to go to war. There are no foreign empires to go to war against, nothing left to conquer. The wars in Dune are among the noble houses, and between the nobility and uppity peasants. And between the occasional secret societies.
I don't know how you see the politics in Dune as a weakness when the authoritarian politics is the fundamental premise of Dune. The essential idea is that Fascism has won at long last, everything else logically follows, and tens of thousands of years later, long after nations as such have stopped being a thing several times over, the world is still at war, and everyone with a birthright wants to be top dog. Fanaticism breeds fanaticism. And the moral of the story is that charismatic leaders may be dangerous to your health.
What did you think it was about? It's not military fiction.
Have you even read the books and the appendixed material?
There are some pretty clear explanations given in the lore to all your points, from the effects of spice to shields to the Holtzmann engine on heighliner ships. Even the ecology cycle of worms, oxygen and water is very well described.
They clearly didn't.
Hmmm I really hope they do

Before Chuck Yeager broke the sound barrier in 1947, people believed that breaking the sound barrier would destroy an aircraft. Some researchers even thought that it was physically impossible for an object like a car or airplane to go supersonic.
People thought the first steam trains were so violently fast (at 50mph) that women should never ride them in case their uteruses were ripped out. 😮

Do you know why many thought an airplane would be destroyed breaking the sound barrier?
magic mushrooms won't accelerate you to lightspeed, but the in-universe logic is that the hard part is not acceleration, but navigating without crashing into a star or into whatever obstacles exist in the folded warpspace or whatever medium they move through iirc.
There also exists the possibility that FTL twists your mind: warped space, hyperspace or whatever. This is used in some SciFi. Passengers get doped or otherwise go to deep sleep. The pilot or navigator must be awake and gets special dope. Some times the aliens drop out in FTL and need time to recover. One day we will discover that ganja only grows so we can stay sane in FTL.

@@mryellow6918 Oh yes, I hate crashing into open space, and explosive gravity. All because wormholes never learned to take no for an answer and always fire all of their guns at once. Was any of that supposed to mean anything?
Yeah the whole point is that they banned thinking machines. Which means no complex machines to compute navigations. So they needed people to do that. The spice is supposed to help mutate people to be able to do that.
Like the Mentats are supposed to be human computers.
In the movie they downplayed this a LOT. We barely see the mentats in the movie, nor do we see any guild navigator shenanigans.
The way prescience is explained in the books and hinted at in the film, is less pure precognition and more glimpsing quantum uncertainty. Paul describes the experience in the book like gazing at a branching river or a tree, with each branch representing a possible outcome. I think what Herbert was going for was akin to being able to see how time unfolds in the events that Schrodinger's Cat was both alive or dead. Almost like the math used to calculate quantum physics made manifest.
Makes as much sense as a naturally occurring stable wormhole, but sure.
Yes, exactly this. This is also how the mentats achieved their functionality of human computers.

@@matux6235 yes, but the shields are also kind of battery/energy-powered which means that you'll be untouchable just for a short amount of time before the energy runs out (because your using it's full power) and then your shield disappears and now instead of being 100% invulnerable you'll be 100% vulnerable from any attacks, melee or ranged 😂
Who needs high tech shields when you got body odor for armor 🤣
As I remember it from reading all the Dune books in the 70's to 80's (my years of reading them), all water on Arrakis is sequestered by the sand worms to be used in their reproduction cycles and spice is the by-product. I think is comes in later books when Paul Atriedes and his son are the rulers.
Water is toxic to the sandworms, they might actually be a silicate based life-form.
The baby worms live in water, I believe to remember. The protective skin Leto put together, becoming a symbiont if wearing it too long. But it was found out only later, that these were the babies of the worms.
And for the science fiction books written in the 1960s, 70s, and 80s (more if you include Brian), it's very poignant and topical today with its environmental themes.
Apparently, Herbert was supposed to write a piece about the Oregon Sand Dunes, which is what inspired him to write Dune. Today those dunes are degrading due to the Forest Service effort to suppress the sand dunes in the 1960s by planting European Grass. Also, the Sand Worms might or might not be a metaphor for ATVs (Oregon has a video about it on TH-cam, but I'm not brave enough to post the url)(The Terrible Purpose of social media;)
Spoilers!
Spice Is the byproduct of the adult worm's digestion. Spice Is literally worm poo.
I’d just like to point out that “the spacing guild” uses spice for navigation not folding space directly. Apparently folding space is dangerous due to collisions and spice gives the navigators a level of prescience that in turn gives them a chance to “turn the steering wheel” before it’s too late kind of thing.
Navigators do not in any way possess any form of prescience
@@Radzood unfortunately they do not. 3rd Stage Navigators (aka Steersman) possess extended awareness allowing them to know the present conditions of space in the entire universe all at once and they possess the ancestral knowledge of how all things in space interact with each other which allows them to predict how any cosmic event will cause interactions with anything along their path allowing them to manually steer a safe course across the universe. it is a fine line between prediction and prescience but there is a line. Previous to Heretics of Dune only Paul, Leto II, and Count Fenring actually possessed any type of actual prescience, and Fenring barely had any at all.
@@MolotDET You're stuck on the 1984 movie. Lynch changed the book explanation into easy-to-digest nonsense. The ships' drives fold space, the 'gators just foresee the safest course.
@@colormedubious4747 the ship drive doesn't enable wormhole travel, the Holtzman engine is an FTL engine nothing more
@@MolotDET Strawman AND goalpost-shifting? Look who's trying to completely fill in his "debate failure" bingo card in a single post. 🤣
FYI, if you read the books you will understand that fold space is possible without spice. The spice allows the guild stearsman to plot a safe path in fold space.
It's only a problem if the story presents it as a "rule" and is then inconsistent with it. That's how good writing works, it doesn't matter if the rules of a fictional universe are different then the real universe, what matters is if the story follows it's own rules. That's why LOTR is a well written story despite having magic, it's very internally consistent.
Exactly. Who's to say that our universe is the only possible way to build a universe?
7:45 even a knife cannot enter this field too quickly. Hand-to-hand combat in Dune involves slowing down the hand before striking the blade
yes this was poorly represented by Deni
Which plays a part in why the Fremen are so good, since they know how to fight without shields since they attract sand worms, while the Sardaukar don’t know how to do that and are worse at it.
No guns, no knives?
Pvt. Frost: What are we supposed to use man? Harsh language? Oops wrong movie🤣
The Dune universe does NOT have faster than light travel. It has "fold space". No Guild ship travels faster than light.
It does have faster than light travel, but only the smugglers use it as it's very slow compared to using the Guild.
Though I just read that on the wiki, haven't read about it in the books yet.
There are a few missing points in the video, but I’ll focus on a couple:
- The shield: in the books, they described as inventions that allow slow moving particles in to allow breathing. It is not explicitly noted if that a side effect or an design choice
- Planetary rotation: it was the 60s. We barely managed to put humans on the moon with the computational power of a Casio watch. I would forgive Herbert for not nailing that part, which is not really the focus of the book to begin with
- Guild Navigators & Spice: Guild navigator were genetically modified humans that overused spice to be able to navigate space travel. FTL space travel was perfectly possible to achieve using machines, but “thinking” machines were explicitly forbidden after the butlerian jihad. The mechanics of spice were never explained, but I thought of it similarly to a super state of what one might thing as “in the zone”, but with numerous more data and sensory input
Others have already explained the water thing.
It would be fun to go over how the sand worms move, though. The most logical answer is that they “inhale” sand and “extract” it with force, like a sand jet ski.
Guild navigators were not genetically modifed. They change becouse of long abusive use of spice, litrely non-stop breath with it. That dramatcly prolong their lives and change their phisical looks, basicly body (brain and mind includs) keep developing and addapt to threir new long live and spice-base enviremant. If i remember correctly, even some of the 1st generations of navigators are alive during books events.
The worm vibrates, reducing the friction of the sand, and then swimming through it
Regarding the force fields that block fast moving objects but allow slow ones through, I always imagined it similar to the properties of rheopectic fluids, a non-Newtonian fluid that increases in viscosity when shear stress is applied (ie the opposite of thixotropic fluids where viscosity decreases under stress. An example from grade school science is a mixture of cornstarch and water, often called “Oobleck” where you can form it into a ball in your hands but when you stop applying stress it magically oozes away through your fingers.
To clarify the association of Spice with FTL travel in the Dune Universe..... it has zero effect on the ship & its ability to move faster than light. The Spice is not used to run the FTL engines at all.
The ship's FTL engines do all the work of folding space, & function completely independent of the Spice.
The Spice only gives the Navigators the ability to see different possible futures... so they can predict the safest path of where to fold space & how much space to fold between jumps.
Prescience is required for this, otherwise the ship might jump into an asteroid, rogue planet, or other celestial object that would destroy the ship.
By consuming Spice... Navigators are able to see all these obstacles before hand, where they will be & when they will be... thus are able to navigate around those obstacles.
The Spice essentially gives Navigators a mental map, by which to navigate the ship.
Before the discovery of Spice... highly intelligent computers would control the ship's FTL engines to warp space & navigate starships.
But there is reason why people stopped using such computers.
Dune wasn’t always a desert, the importation of sand worms made it so, as their life cycle encapsulates water. Where ever they came from they went wild on Arakis free of what ever their natural predator was.
Environmental concerns were very much a theme of Herbert.
Herbert begins to imply in his last books that they may be bioenginered creatures.
@@melissaharris3389 Which Herbert?
Late to the party, but this is the part that always made my brain come to a screeching halt and go "WHAT?!" Because it's said that the worms were already there when Arrakis was discovered. It wasn't until thousands of years later they realized the worms were not indigenous. So humans had nothing to do with them. Yet over 10,000 years, multiple galaxies and over 13,000 worlds later there's zero evidence of there ever being an alien civilization anywhere, let alone near Arrakis.
The God Emperor never says either making one wonder if even he knew where they came from and who brought them there? If he doesn't, then the mystery of the sand worms becomes more mind boggling, because what could prevent him from knowing? The questions raised by that revelation are just insane, and it's almost entirely glossed over like "NOTHING TO SEE HERE, FOLKS!" When it's possibly THE most interesting thing in all of Dune.
@@chaospoetThere are alien civilizations in Heretics and Chapterhouse, we just don't see them.
I think you've missed so many details here. Like:
- Arrakis was already terraformed.
- Freemen are highly advanced in technology (why would not they? They are settlers from other planets
- With spice, you see not "the future" but "possible futures", which is more like the ability to process more data than we can imagine but still not breaking any physical laws.
- Shields need to pass slow-moving objects to allow you to breath (also part of the plot, but not for fight scenes)
etc.
Don't forget that the shield technology also has another plot device: Interaction with lasers causes nuclear explosions.

On the topic of needing to use pumps to keep the nano-porous membranes clean. It is explained in the books that the suits harness body movements to power various pumps around the suit. While the book only says this is used to move water from where its collected from the body to where it gets filtered and stored, it also does say that fremen suits are extremely superior to the common suits everyone else uses, and I would not be surprised if their suits doubled down on the pump pressure (making movement more difficult but they're not "soft people") to continually scrub their filters as well.
What's all this about the variable rotational speed of Arrakis? I don't recall anything about that in the Frank Herbert Dune books, except in one of them, he wrote that the planet's rotational axis was almost perfectly perpendicular, effectively not tilted at all.
Maybe all this nonsense is in the Brian Herbert/Kevin J.Anderson "heresies" (😆) of prequels, sequels, pre-prequels, post-sequels, and seemingly non-stop attempts to wring as much money as possible out of Frank Herbert's sci-fi masterpiece.
Brian Herbert can't write to save his life. I read _one_ of his books over 30 years ago, & it was abominable.

I think we were supposed to get to that after we were done with The Political Effects of Time-Vision: Immortal Dictator Finally Emerges, it's just that the final book is written almost deliberately to suggest Duncan is going on an adventure, so that's what Brian wrote, Duncan's Excellent Adventures.

Paul Atredes and his going native does not lead to him becoming a Luke Skywalker type, as you might think, but rather, he becomes like Annakin, and then his son becomes the worm man Leto II in the sequels.
The whole premise of the story is: "Don't worship hero's". They're only human and they have faults.
Dune is older than Star Wars. Dune was published in 1965. Star Wars was released in 1977. Star Wars copied a lot of ideas from Dune.
So it would be more correct to say that Anakin becomes like Paul, except they are nothing alike. Sure, both are "chosen ones" from a young age, like Harry Potter, and both suffer from occasional future visions, but that's where the similarities end.
Anakin is more like Luke: Constantly complaining, impatient, and bloody-mindedly chasing a noblewoman.
There's a lot more water on Arrakis than is made apparent in the books or movies. You need to read Children of Dune and look for the sand trout. They are a larval phase of the sandworms, and they lock up water. They go into this further in the 6th book, where they use sandworms to terraform another planet into a desert planet by introducing the sandworms. The water isn't going away, it's being locked up by the trout.
There is one other source of water on Arrakis: the north polar icecap. There are no worms there and no spice. Why don't the fremen mine ice for water there? The books hint that it is very cold there and ice mining is extremely hazardous.. And since the main draw of Arrakis is the spice, the vast majority of people simply don't go to the north pole.
In the first book ice mining was indeed mentioned. But it was done by city people - those living in areas naturally protected from Sand Worms. In those "civilized" areas Fremen are not welcomed kindly.
From my understanding from reading the second book, the future sight offered by spice follows more of a quantum model. In that you see several possible futures and can tell which ones are the most likley to occur. Basically it is about probability but not set in stone. It is difficult to change what you see as it is more unlikley to happen, but not impossible.
A whole series on Sci-Fi realism linked with current astronomic discoveries could be nice.
I'd gladly watch a dissection of Star-Trek universe in relation to the actual reality of cosmos as we know it.
The setting of The Expanse is mostly rooted to known science, Protogene and Fusion Power beside...
First thing that comes to mind is that Warp speed would be impossible. Our current understanding of physics says that any attempts at light speed or faster than light speed travel would break causality, including any sort of warp drives or even worm holes.
I think you've missed a key point about space travel from the books. Its been a little bit since I read them myself, but the concept was "Traveling, WITHOUT moving..." The notion of space folding is not that you are traveling faster than light, not in any "conventional" sense as put forth by most Sci-Fi. You aren't necessarily even "traveling through" a wormhole (although wormholes may be involved.) The idea was that you "folded" space (which was done by the highliner itself, and its Holtzman drive, not by the navigators), in effect bringing two points in the universe together "through foldspace (which is where the navigators prescience is required, to find a safe path through this "foldspace"...and as I understand it, for the SPACE BEING FOLDED...not so much the highliner itself!!) at the SAME PLACE (the highliner). You then simply ARE at the other location...there is no speed involved, not actual movement, no conventional FTL. You simply "fold" yourself through "spacetime" and are then somewhere else. Its an odd concept, but one that is theoretically supported by Einstein's relativity (i.e. Einstein-Rosen bridge, wormholes). The Navigators, saturated with melange, are capable of a limited (compared to Kwisatz Haderach anyway) form of prescience that allows them to avoid potential collisions in the foldspace, which is what made this form of space travel safe and effective and allowed travel throughout the known universe. I don't believe that the modern depiction of this space folding in the new miniseries by HBO, is actually all that accurate. The way they show the highliners is more like they are "portals", where if you look or travel through them, you arrive somewhere else. That isn't what I remember from the book...the way the book read, you had to be within the space of the highliner when space was folded in order to "travel" and if you were not within that space, then you didn't travel. The Dune miniseries from 2000 seemed to depict this more accurately, and I guess so did the original Dune from 1984...I've been disappointed in the relatively cheap effects and approach to this form of space travel that the newer movies have taken. It seems like a copout, to avoid even trying to depict how this form of travel might look like. -\_o.o_/-
You are right about how the folding space works. I think Villenuve made a mistake depicting the Highliner as he chose to. But it is a far out concept to visually depict. As those inside see nothing and the ship just dissappears and reappears.
Even Herbert doesn't 'show' it. He just info dumps it on the reader as Paul's inner monologue.
I think the idea was to show the ship existing at both points in spacetime at once, but it doesn’t come across unless you're already familiar with how it's meant to work from the books.
Strangely enough, Star Wars (Dune's bastard child) depicts FTL via wormhole pretty well.
That's what a wormhole looks like: You enter at one end where it's invisible, and exit at the other end, where you see the entrance. Entrance and exit are the same volume in spacetime, but traversal is unidirectional.
The heighliners create that wormhole by folding space. They have to be at both ends for that, naturally.
In the book, Paul never sees a heighliner. He enters a shuttle, and an unsolicited time later he exits a shuttle. Maybe the same shuttle. Compartments aboard the heighliner are mentioned, but not what they are.
In the books, the holtzman field is created by a holtzman generator... which frequently overheats when heavily taxed by incoming projectiles. Presumably the impacts against the shield are feeding back into the generator. Another interesting detail from the books is that the shields react explosively when hit with lasers... a fact that was not known until the shields were already heavily deployed among military personnel (turns out, lasers were an ancient weapon that wasn't very effective due to energy requirements) Someone ends up firing an old museum relic at Theo Holzman himself (the named inventor, but not the actual inventor), who was wearing a shield, and it destroys an entire city. The physics of that reaction are also not covered in the books (where does the energy come from for an explosion the size of a nuke, when the interaction was caused by a battery powered laser and a battery powered shield generator?)
About the water on Dune: the water was always on the planet, but it was tied up by creatures called "Sand Trout". These creatures aggressively find water and absorb/trap it under ground. The sand trout are the larval stage of the sand worm. Once the water is trapped, some sand trout become Shaitan (Later called Shai Hulud). Sand worms cannot live in the presence of water. The terraformers eventually realized that destroying the sand trout would release the waters, which would destroy the worms, allowing water to flow on Arrakis... though even after this was done, there wasn't enough water to have full-blown oceans on the planet... but rivers on the surface did exist.
The Guild navigators do not fold space; the Holtzmann effect does that. The Guild navigators only see the path.
Hence the "Navigator" part of their title.
10:30 Isnt spice red and not blue?
It's blue in the books, hence the color of the Fremen's eyes
@@Zond3r No.
@@Zond3r No, it's a brown or orange color in the books.
Spice is worm poop.
It's both. Concentrated spice essence is blue. Hense the blue within blue Eyes of Ibad of Fremen and spice addicts. The mature spice becomes redish after it erupts from deep beneath the sand; it's then oxidized and dessicated by Arakkis's intense sunlight and dry atmosphere. It's at that stage it's granular, redish, and smells vaguely of cinnamon.
Spice isn't blue, the cisterns aren't wells but the collected water of generations and the terraforming of Arakis is done by billions of people from across the galaxy making pilgrimages to Arakis to pay homage and leaving behind water vapor from breathing and all the other ways people lose water.
spice is blue in the books
It's both. Normal spice harvested from the sand is redish orange due to oxidation and drying under Arakkis's sun. _Very_ concentrated spice essence like the Water of Life or Sapho, used by Mentants, was blue.
@@melissaharris3389 The water of life was bile from new born sand worms I kinda thought it was its own thing yes similar but diffrent and I dont think sapho was spice or derived from spice at all but i could be wrong
As a soon to be designer of electric aircraft, and only 1:35 into the video, looking forward to your analysis of the 'ornithopters', although they are not in fact bird like, but giant dragonflies. In reality, on Earth anyway, these flying machines would explode into pieces of mechanical parts on power up if such huge wings flapped that fast against the soup of terrestrial Terran air.
i wonder if the shields would come in handy here...? like the craft itself is protected by the shield and the strong forces just make sure that no energy is passed onto the frame? of course, when we see how they operate, the crafts should glow highly blue when they are active then, i guess.
Dragonflyesque indeed. However it also reminds me of a hummingbird's flight technique. Large proportional wings, like you said, would be absurd. But perhaps you could think about a vehicle with tens of thousands of tiny mechanical hummingbird wings. Would that work?
Not exactly, look up the youtube video "I built a simulated ornithopter and the results surprised me", it would be more viable than people think, even on earth. (And the gravity on arrakis is lower than earths, regardless of what some of the wiki information says, the planet is quite a bit smaller than earth due to the time it takes for characters to travel across the surface, based on speed)
@@alexejfrohlich5869only some of the ornithopters have the shields apparently I'm reading the first book currently
I loved the movies but I don't think they managed to get across the harshness of Arakis. They seemed fairly comfortable wandering around.
During the day and never wearing masks, just accessorizing them like a necklace
Gotta show the actors' expressions.
It doesn’t make sense to terraform Arrakis in its entirety. The entire value of the planet is in its spice, which as we know is deeply tied in with the sand worms.
If they terraform the entire planet, it would mean the extinction of sand worms, and no sand worm=no spice and no water of life(Arrakis Whiskey).
They’d just make themselves a backwater planet and worse, it would mean that interstellar travel will no longer be possible, leading to the collapse of the galactic civilisation.
I kind of feel like the title is clickbait, either that or there is a lack of understanding about how things work in Dune. Yes Frank Herbert clearly didn't care much or study much about astronomy. Yes, quite a bit of the technology in Dune hasn't been discovered. But you have to remember that Frank Herbert wrote Dune in 1965.
The first exoplanet wasn't discovered until 1992. Astronomy in Dune is actually quite a bit better than even science fiction books that came out after 1965. Original Star Trek is far more inaccurate and the original series came out in 1966, and I'd argue that even what is being created recently is less accurate than Dune. Star Gate is also highly inaccurate, the very idea of using constellations is ridiculous from a scientific standpoint. Most of the constellations we see in the sky would make absolutely no sense if seen from even a slightly different angle. Basically almost every science fiction show and movie is probably as bad or worse than Dune.
Then you have the technology. The faster than light travel is highly dangerous in Dune, it's like traveling through chaos in Warhammer 40k without the demons but with far more likely chances of being destroyed. Space Navigators basically see into possible futures using spice, but in a very specific way. Basically it let's them pick the best parameters which changes the exact travel path and avoid being destroyed. Without this nearly all ships traveling faster than light would be destroyed. This also isn't exactly the same as seeing into the future. It's like taking a drug that increases your predictive abilities and ability to infer the future. So imagine that you have some type of sonar and you need to navigate a lake that is filled with icebergs, without hitting any icebergs. Predicting exactly where the icebergs would be is almost impossible, just figuring out where they are from sonar would be difficult. But taking spice increases your brains ability to compute all of this and figure out where the icebergs will be as you travel past them. This can actually be done using computers, I think in one of the prequel books that Frank Herberts son wrote they used computers and ended up with only around a 10% destruction rate for ships traveling faster than light, and this likely could have been improved over time. Space navigators still screw up sometimes, and they are very much in demand because it's not something that all humans can do well. Kind of like how the best ATF controllers almost always imagine the location of things in 3d, whereas most people only think of maps of a building or area in 2d. I don't see how any of this is less scientific than say a warp drive in Star Trek?
For shields I get that having a shield itself doesn't seem likely. But you see shields in a number of other science fiction shows. It being modulated to let slow things through makes some sense due to needing to breathe and that you want to be able to touch objects and also walk around. If it blocked everything you wouldn't be able to touch the ground, pick up a weapon or ammunition that was outside the shield, and you would need your own source of air inside the shield. There is also an interaction where high energy weapons will cause an explosion when they hit a shield. So combat basically is done with knives and various ballistic weapons, but mostly knives at close range that can go just slow enough to get inside of the shields. It's actually a part of the books that the movies screwed up. When Paul was fighting the first time he had trouble killing his opponent which the movies showed, but it mostly wasn't because he was hesitant to kill someone, it was because he was trained to fight someone that had a shield. When fighting an opponent in a shield you can use your full speed to dodge their attacks, but when you attack them you have to do it slowly so that you can get through their shield. Seriously I think that the teleporter in Star Trek is far less believable.
Also the sandworms do rely on water to survive. The life cycle of a sandworm is kind of odd. Basically they aren't one creature, they are actually a kind of hive of what are called sand trout. If exposed to too much water a sandworm will "die" and turn back into sand trout. Groups of sand trout absorb and almost kind of lock water away from the rest of the environment. Imagine a layer of sand trout that is absorbing water just above the water table, but across an entire desert planet. They release spice as a byproduct. And they eventually merge and become sand worms which then live in the drier area above the water table. Then the sandworms die and create more sand trout. Basically you put sand trout on a planet and they will slowly transform it into a desert world. If you want to reverse the process you just have to kill all the sand trout, the water will be released and kill the sand worms, then you kill the sand trout that were released when the sand worms died. So they get plenty of water when they are sand trout, and they continue to get a small amount from what they eat. Likely if they don't get enough they just break back apart into sand trout, or if they get too much they break apart because the sand trout start feeding on the water instead of maintaining the connection as a sand worm. Yes it's an odd creature, but I don't think it's that much odder than many other creatures in other science fiction.
By precognition I always assumed that it's a future prediction by extrapolating the current state of the universe, not some baked-in future, so it can change for sure. Paul and other future kwisatz Haderach has to actively act to shape the future. No paradoxes.
Anyways, I like the Dune universe a lot, though most elements of it are there just to get the plot going. It's not a bad thing because it's pretty well worked out, but it definitely places Dune much more into the fiction/fantasy category for me.
The new Dune movies are a fair and awesome adaptation of the first Dune novel.
No
Yes. I think the second part made some odd choices, but the first was just awesome.
For example, Margo Fenring. I assumed that she would just pretend to be one of Feyd's groupies, not how they depicted it in the film. Or the surface of Giedi, I would have assumed life on that industrial planet to be basically all underground. And why they didn't use that effect for the nuclear explosion instead.
But the interaction between Feyd and the Beast was great.
The emperor came across as borderline senile though. His Sardaukar are religious fanatics, he is their living god, he is supposed to be terrifying, in a Christopher Walken kind of way.
Anyway, the end was a great payoff, even though it deviated from the book.
@@davidwuhrer6704 The presentation of the Emperor was odd. He seemed dumbfounded the whole time.
@@SuperFranzs not even talking about how in the books he looked 40ish, not some senile grandpa
@@GodOfWar05100 I understand that one. On film you need things to be apparent by just seeing it. It would feel forced to have a line of dialogue say that "by the way this emperor guy is like 70 years old even though he looks young".
Sorry if someone mentioned this already, but the force fields could stop everything from entering it, but if you set it to do that it would also block fresh air, so for personal shields you have to let slower stuff in to be able to breath. Spaceships on the other hand would normally turn them on to the max.
8:00 Force Fields = the reason those personal shields in Dune don't make scientific sense is because the author was using them as a narrative device (foreshadowing)
_"slow blade penetrates the shield"_ is actually a metaphor for the subtle treachery associated with the nobility
Imagine a video like this but for the celestial objects and events of Warhammer 40k.
One thing, Alex, you didn't even touch on, is where does the planet get all of its oxygen from in the first place? Zero greenery to speak of, no oceans for plankton, and absolutely nothing for photosynthesis. What on that planet produces oxygen? Never mind an atmosphere very Earth-like. That's always been my biggest question.
there's tons of plankton in the sand. Its what the worms eat.
@@vileluca yeah, I know about that plankton. Of course I take issue with that as well. Plankton require water to survive too and on the surface in the sand where they live is dry as well. At any rate, thanks for the reply.
The sand worms exhale Oxygen. It’s a byproduct of their chemical cycle
the worms and all it's stages create oxygen
Dune was once a lush jungle planet and the remains of the desiccating plants buried under the sand produce gasses which are processed by the sand plankton and produce o2.
The one scientific necessity ignored or not realized in the creation of harsh desert planets such as Arrakas or Tatooine is the basic biological principle of an oxygen cycle. Oxygen is extremely reactive and must have a mechanism such as photosynthesis found in plant life to make it available to breathe or it will quickly react to most all but a small handful of the other elements.
Not sure about Tatooine, but on Dune oxygen is created by the sand plankton's interaction with the desiccating remains of the ancient jungles which existed on Arrakis before the sand trout were introduced. Plant biomass buried under the sand releases gases which are processed by the sand plankton and turned into oxygen.
@@MolotDET Thanks for taking the time to explain that, but it still seems like a stretch. Of course giant worms that can move at 80 miles an hour through sand are also a bit of a stretch... :)
The shields use/issue is twofold: first, slow moving objects (like oxygen and CO2 exchange would have to take place so that the wearer didn’t suffocate). Second, the slow moving objects getting through were designed to show the limitations of technology.
Dune was originally a lush and verdant planet. The Sand Trout and sandworms turned it into a desert. It was already that way before humans arrived. Only Frank Herbert knows where the sandworms came from. They're not native to Dune. Some other comment said that Sandworms were smuggled to other planets but didn't survive. I think they should have smuggled Sand trout instead. But the characters in the book don't fully understand the life cycle of the Sandworms and the attempts were doomed to fail.
Bless the maker and his water.
Tell me you didn't read the books without telling me you didn't read the books
Spice doesnt make things go the speed of light. It allows the space navigators make the necessary calculations to safely travel through space. Its needed because thinking computers are banned in dune
Darn, I hate it when science fiction doesn’t hold up to real life science.
the stated explanation of faster than light constraints here, does not apply to (theoretical) space folding to effectively achieve faster than light travel. warp drives do not violate known laws of physics. neither does quantum teleportation. the speed of light only restricts how objects with mass move through relativistic space, not how space may be compressed.
Spice isn't blue. The shields allow things generally moving slower than 6 cm per second to pass through so that air can pass through so the user can breathe also so that they can handle objects like their swords
The melange ESSENCE is a blue LIQUID. Spice powder is never described as blue. It is described as "glowing blue," in God Emperor of Dune, and the gaseous form is orange. "Glowing blue" could indicate a phosphorescent glow, and not necessarily refer to the base color of the material. I am currently rereading the Frank Herbert Dune novels. I am on Heretics of Dune, and so far that's about all of the descriptors used. The textiles made from "spice fiber" are described as red, and taken all together, I imagined the spice to be deep reddish brown with a blue phosphorescence. I know some are adamant that the spice is blue, but Frank Herbert consulted on the original movie, and it was cinnamon colored there. If he considered the melange to be blue, especially considering how rare blue tends to be in nature AND how often he used other color descriptions for other aspects of spice and spice products, I think it would have been blue in the original movie.
I was hoping to see the lasgun/body shield interaction in the first movie, as mentioned in the book. It'll be interesting to see how they render the stone burner explosion in Dune Messiah. I have an old paperback copy of the Dune Encyclopedia, which was considered cannon until the prequel books came out.
Sell me your copy of the dune encyclopedia please
The space guild doesn’t necessarily see into the future as much as they use the spice to make the calculations. There are no computers because of the past war. The navigators of the space guild are basically human supercomputers. They also are not the same as normal humans.
The larva state of the sandworm actually seeks out water and stores it, And actually the planet aracquest was terreformed by the sandworm larva because it was Found that the larva did not originate on dune. there's an encyclopedia
I think the reason the shield is able to counter such high velocity objects but not low velocity is because it’s really efficient at using the force and kinetic energy from the object to push back on the object itself. So the harder and faster the projectile pushes the shield the more force is applied back to the bullet. Of course it would make sense if there’s a threshold, too much force over too much time can break the shield while too little force could not generate enough energy to push back on the projectile.
I love your videos but I find this to be a rather shallow and clickbaity attempt to jump on the current Dune bandwagon.
We know it's science fiction, it's implied that some of the technologies used are fictitious to us, either because they are too advanced for our current understanding (you didn't mention that the story happens over 10,000 years into our future, it's pointless to compare their technology with our current one), or because they are just made up to suit the story. You don't need to claim that Herbert "got it ALL wrong" (as per the clickbait video title you used) because this is not a science paper we are analysing, it's a fiction universe.
I also got the feeling that you have based your whole analysis on a rather shallow watch of the current films and some wiki reading, but you missed some key ideas of the original novels, such as the real use of the spice or the complex implications of the sandworms.
I think you do great science videos and I'll keep watching them with pleasure, but your strictly scientific approach is not the best to analyse fantasy settings like this one.
My comment was attempted as constructive criticism, I hope I don't sound too grumpy haha.
Cheers!
The impression that I got from the book and the movies is that Spice doesn't allow one to see the future. Instead, it increases one's perception and calculative ability to the point that they can deduce possible futures and pick the ideal outcome. The book also mentions a subtle communal empathic connection the Fremen share due to their constant spice exposure, which may be a result of the increased sensory information.
The book does have a chapter going over the terraforming process for Arakis, which described a fairly plausible cultivation of fundamental systems until they could be come self sustaining and allow for more complex layers to be built on. The movies trim a lot of the specifics in favor of narrative clarity (in addition to some tasteful rewrites), but the book gets pretty particular about a lot of the theory. I haven't read past the first book, so I can't speak to how they develop.
Ive tried spice and couldn't navigate out of a my own bedroom.
😂 Need more if you want to accurately fold your way to the fridge.
One point. The guild mastered faster then light travel, but anyone can do it.
It’s dangerous. The spice gives some humans the ability to see the safe path. The spice does nothing to make it possible only possible to see the safe path.
Considering how it's impossible to pull yourself out when you're half-buried in sand, I'd like to see a serious calculation of how much power a sandworm needs to propel itself through the sand at speed a couple of hundred meters deep. And how many calories they'd need to get that much energy.
Eh, it is a solved problem. Specifically, by Tremors back in 1990. They work like a combination of snake and fish, with little fins that act like sand-oars.
Dune is as much about science and technology as it is about geopolitics, history, colonisation, ecology and psychology.
Note: Replace spice with fossil fuels and magic shrooms and you get the connections to Earth colonial history and geopolitics.
I don't want to be angry anymore.
About what, the movie? I don’t blame you there.
The shields could have some form of antigravity effect, but the science doesnt seem to back up that antigravity exists. It could be a non-newtonian liquid effect but with particles. That would explain why the slow blade penetrates the shield.
Work of fiction turns out to be a work of fiction 😮
My understanding of how the Heighliners work (at least in the current DV films) is that they aren't like stargates where you'd need one above every planet and link them. They're ships; they gotta move. But the way they move is via spice which bends spacetime. When a Heighliner is active it exists in two spaces at the same time. This is why you can see through them into other star systems
The spice does NOT bend space. The Holtzman engine in the ship does. The navigator uses spice to 'see' a safe path to the destination. The engine creates the path of the wormhole that was ploted by the navigator. Then space is instantly folded around the ship to "move without moving".
Dude, don't take better help as a sponsor. They're a scummy business and it takes like 5 mins to learn that
The shields always felt real to me. Like when you slap water, it seems hard, but if you touch it slowly you can push into it.
Most real life a science 'rhymes' like this.
The ships in Dune don't really move FTL. They travel without moving. They make the two points in space the same. The effect in the film is a departure from the book. Dune 84 got it better.
Physics today can't really explain distance or the difference between 2 points in space.
Exactly. The Heighliner is in orbit above planet A, the Navigator chooses the route (though probably not using beams of light from his mouth), the Holtzman drive folds space so planet B is for all purposes directly adjacent to Planet A, and when the drive shuts off the Heighliner is in orbit above planet B. From a frame of reference outside the universe it was the universe that moved, not the Heighliner.
No, Lynch didn't get it better. His film has very little to do with the book and gets pretty much everything wrong. It's a very different film.
Physics _can_ and _does_ explain distance: First, accept that the speed of light is a constant. Distance, then, is a function of the time it takes for events at one point to affect the other. (So simple that most people can't wrap their head around it.)
Dune is barely sci fi, it’s odd to me how everyone classifies it like that when it has much more in common with fantasy
It's called Sci-Fanstasy or soft sci-fi. Star wars could be considered Sci-fantasy, Dune as soft-scfi and Foundation as hard sci-fi (being that it is based on mathematical sociology).
Like fantasy, there are many sub genres within sci-fi. Dune is sci-fi, just not hard, though harder than star wars.
Star Trek is all of the above depending on the episode.
Though there are many distinctions between these sub-genres, remember that politics and international relations are sciences.
The points between certain fantasy books and soft sci-fi can become blurred if both discuss socio-political issues that relate to our conceptions of said subject. Usually one chooses the theme of magic where as the other chooses technology. Furthermore, one chooses a fictional past, the other a future. Though, again, this isn't always the case.
I'm guessing you're one of those, if it ain't essentially a physics paper it's not sci-fi, folks? No judgement, just curious
I agree with the original comment. Even by soft sci-fi standards, it comes up short. Don't get me wrong, it's a fantastically rich tale, with many fascinating concepts and intriguing thoughts on the human condition. But even Herbert himself said the science is only tangential to the plot.
@@GoldenMinotaur Not really, but I do think science fiction as a genre is based on the exploration of scientific concepts. Dune doesn’t go in depth into anything scientific, what it does go into is only in service of its themes and narrative. Why I think it’s more closely related to fantasy though is because it hits on almost every traditional epic fantasy trope, except it deconstructs and criticizes them.
@@wlot28 I respect that. To me science fiction has always been a vessel to convey controversial or sensitive concepts to a reader that might disconnect from an ego response if they feel too connected to the antagonistic aspects. But that's the beauty of books, we each own our own experience, not even the author supercedes our interpretations
To be fair arrakis is an anomaly even in the dune universe. Especially since arrakis is the only planet that have the spice Milange.
i still find it hard to believe there would be no satellites orbiting such an important planet with the most valuable resource ever
Read the book and you’ll see there are artificial satellites orbiting Arrakis. The Fremen bribe the Spacing Guild with spice to avoid certain areas where they’re doing things they don’t want seen by the Harkonnens or Empire.
In the first book it was mentioned that Fremen pay exorbitant bribe in Spice to Trading Guild to specifically NOT notice any curious things happening in the desert.
there are actually weather control satellites which keep it from raining at all to protect the spice cycle
The first book also states that the Atreides had weather satellites from IX in orbit around Arrakis.
16:20 "Crawford's gray shrew" or commonly known as "Desert Shrews" are known to sustain themselves entirely from prey, being able to survive without any additional water.
My main quibble with the science of ‘Dune’ is the ludicrous use of ornithopters on a planet mostly comprised of sand. 🤷♂️
I would think any sort of machinery in a sand environment has to be a nightmare for the people who have to maintain the equipment. Good for the filter business I suppose though.
They need flying machines to get anywhere quickly, and it sort of makes sense that future flying machines resemble naturally evolved designs.
The indigenous people know better than to use flying machines, but the off-worlders would be used to them (and labour is cheap anyway), and can't be expected to learn how to ride on the local fauna.
This is one of my favorite channels, but nit picking fiction is one of my peeves, so I'm gonna pass on this one.
If sand worms eat sand plankton, what does the sand plankton eat? There seems little or no plant life on Arrakis, so the ecology can't work.
Yeah nothing makes sense when it comes to food, there are millions of Fremen living in the deep desert and there is nothing to eat. You can't grow or hunt enough food to sustain such a huge population with the storms. Unlesss you have massive giant underground hydroponics but that would take a ton of water and they keep losing water in various ways when they go out. The water is very expensive so they also can't go to the villages and buy it.
So many survival stories lack the food aspect, that we can't survive on a few tomatoes in asoup, we need 2000 calories a day at the very least if you are doing any sort of physical labour. Knife fighting in the heat? 3000. Galons of water. Frank Herbert describes how the Fremen have dry bodies, skinny from lack of water in their tissues, blood barely drops. If a human lived like that he'd be dead.
The books describe parts of the ecology. Herbert was particularly interested in that aspect.
The Fremen use wind traps to extract water and energy from the air. There are also mice and bats living in the desert. And sand trouts are also a source of water.
This is the first video on Dune 2 that was even slightly critical of it. I really enjoyed it, as I do all of your work. Thanks you!
Its a story ppl calm down
Grow up man, this a informative video
It is by will alone I set my mind in motion. It is by the juice is sapho that thoughts aquire speed. Thoughts aquire speed and lips aquire stains, the stains become a warning.

Remind me not to go to a movie with you.😁
.........i went to see "Titanic" with a history buff.............worst movie EVER!!!........lol
@@ZEROmg13 Yup..😁
You don't need spice to fold space. You just need it to do it succesfully. 12:30' magic mushroms where never acceleration device 😊
love it astrum! ignore the haters this kind of content is amazing
Dude didn't even read the books and it's painfully obvious. You can be critical and not be a hater.
@@xenocide1307This!!
Spice doesn't cause "actual" prescience, so to speak. It just makes you really, REALLY good at making distant predictions from limited information. So you see the future as a sort of probability field. But no new information is being transferred.
We need to practice hand to hand combat incase the enemy is wearing a shield that can only be penetrated by epic, sexy, well choreographed knife attacks.
Yeah, the scene in part 1 where the Power Ranger danced his way through all those opponents was laughable 😂
It’s amazing this was written so long ago in the 60’s, some of the concepts are so modern and timeless, it’s not aged in a way like a lot of bad sci-fi from decades ago where the ‘future’ versions of concepts from the time just seems dated and silly today
boring, channel blocked, thumb down, middle finger up
On the topic of needing to import water from other planets. That's actually been happening as of the books. Its one of the ecology mysteries on Dune that is explained when Paul meets the Fremen. The Harkonens and later the Attreidies import huge amounts of water every month to keep their coffers full and keep their palace comfortable and livable. This water regularly was lost, the noble families weren't much for conservation when they were so wealthy. At one point someone (I forget who) questions where the water is going, I mean, how much water can the atmosphere evaporate before the air starts to get a little less dry. It has to be going somewhere.
The cisterns that the fremen keep aren't just people's body water like it seems to imply in the movies (as that would just slowly decrease the amount of people that could live on Arakis, since that water is needed for life). The water nets they use to catch water vapor from the wind and other techniques are the Fremen constantly harvesting, all day every day, across the planet, the water that is imported by the noble houses, and then lost to evaporation. They were already preparing for the beginning of the terraforming with offworld water.
Also, most of the planets water is locked deep beneath the sand by Sand Trout (the larval stage of the sandworms).
The very act of sequestering the water is what eventually creates spice.
Okay, Neil Tyson
Has anyone ever wondered why they dont just stick an icey asteroid or comet in orbit around arakis with their obviously exceedingly advanced space travel technology, and then just...mine it for any water needed by the human population? You dont NEED to destroy the sandworm habitat if you just...keep the water away from them, in the human-habitated areas. Or has someone already gone over this concept?
It is mentioned in the books that water is mined from Arakkis's northern poler icecap and imported (at great cost) from off world by the Arraken: the people that live in the cities and are mostly decendents of off worlders from the Imperium. The Fremen live exclusively off the dessert in their traditional way.
@@melissaharris3389 Yeah but I'm saying like...the fremen could also just do that. They know how to use technology just as well as anyone else
Dune is a made up fictional story. Come on Astrum. Do better.
We'll get through this together. One step at a time. One day at a time. We shall rebuild.
This video is entertainment. He's not critiquing it seriously, you dork. It's just a device for pop Sci entertainment. Were you just born? 😂
It’s a bit of fun. This is still allowed.
He could always address how massive your mum is that she is slowing down our day by 1hr a week. But everyone knows that
It's science fiction. He's analysing the science part, nothing wrong with that :D
Thanks for 19:05 allowing Dune to be more like cool story and less like scientificaly acurate. Might SciFi films should have a rating on "more like on the beeing science acurate side" versus "more at the making the story as cool as posible, even if it violates science" part.
