Keep up the great quality!!! I follow you since 1 year and when i watched your first vid i legit thought its an uploaded documentation from the discovery channel or something like that. I love how much work you put into these videos and you really got me into futurism
or this... “AM said it with the sliding cold horror of a razor blade slicing my eyeball. AM said it with the bubbling thickness of my lungs filling with phlegm, drowning me from within. AM said it with the shriek of babies being ground beneath blue-hot rollers. AM said it with the taste of maggoty pork. AM touched me in every way I had ever been touched, and devised new ways, at his leisure, there inside my mind.” ― Harlan Ellison, I Have No Mouth and I Must Scream
I'm so very excited for this collaboration with JMG. Isaac, and JMG are by far, and away my favorite you tubers. Thank you so much for the fantastic content you guys, and your teams provide us with!
I’m do glad to hear you address the inevitable divergence and diversity inherent in colonizing a galaxy! Of course I never would have expected less from your channel, but it does bother me as a biologist how most sci-fi doesn’t address it. Even when there are older civilizations they tend to be somewhat homogenous and their members are archetypal.
It was the year 12042. The immortal Isaac Arthur was on vacation on Zchri+Ar9qyn - a newly colonized planet in the Sagittarius Arm. After unpacking in the hotel, he decided to go to the hotel bar to have a drink. In there, he saw a woman sitting lonely at a table with a cup of some pink liquid in her pedipalp. Curious, he asked the bartender for the same stuff. He sat down, greeted her and took the sip from the cup. He gagged and spat on the floor. The liquid was cold (even though steaming), sticky and sour. What's worse, something flapped on his tongue like a fish when he had it in his mouth. The woman chuckled. "Have you never drunk coffee before?", she asked flirtatiously.
That transition to Godier was so smooth. Nice editing. I heard the twist in voice and the unique absence of the speech condition, and I was like "Oh, that's right, collaboration." Great video. As quality as your videos ever were.
My girlfriend and I always play your videos at night when we're going to sleep. "Wanna put on some wascally wabbit?" "Yep" Always interesting and relaxing. Thanks and keep it up!
Hunter Holly, not really, but at this point, after watching a few youtube people sharing their experiences and research, as well as bunch of analytics, I think we have pretty solid grasp of what the algorithm is promoting
I shit you not , SFIA is miles better than anything on Discovery science (Yes, even better than Through the Wormhole) The only thing that comes close is Nat Geo's C O S M O S
Nothing comes close to Carl Sagan's Cosmos,nothing ever will.Mr.Arthur's content is brilliant possibly the best on youtube,but the original Cosmos towers over all.
I go back to the original cosmos series from time to time, some of my children are still quite young and we listen to it on Sunday. I have made posts on those videos referring people to this page. Hopefully that helps spread the word. S.F.I.A.
Though not true K2 level, Banks culture novels handled the scope and diversity of advanced galaxy spanning civilizations as well as one can expect before you probably start to lose reader engagement and emotional involvement...
Not even Warhammer 40k, despite all of it's bragging fanboys, gets it right. I mean, the Imperium of Man being a galaxy-wide power while it has only 1 million worlds? Utterly laughable. There are an estimated 8.8 billion potentially habitable worlds in the galaxy. 1 million literally isn't even 1% of that. It's more like 1/6 of 1%, and that's erring on generous. A galaxy-spanning civilization is required to have at least hundreds of millions of inhabited planets or its not even worth referring to as "galaxy-spanning".
Joel Gawne from my knowledge of the 40k universe, the 1 million worlds are actually spread across the entire galaxy ( because the way they travel is inconsistent and leads to them accidentally Landing in another galactic quadrant sometimes) so while they may not even be close to the total habitable planets, these planets do in fact span the galaxy however one important thing to note is that the Imperium of man is fighting dozens upon dozens of existential threats and at the same time are destroying the entire surfaces of planets and sending billions (trillions depending) to their deaths almost on a weekly if not daily basis, so if we are to take away those factors the Imperium may very well have been a true galactic empire where they have colonized most of the habitable planets instead Of literally fighting enemies that are practical gods. Also you are forgetting 3 major factions that may very have colonized most of the galaxy. 1. The old ones (these were believed to be the first to create civilization and mastered practically everything and were living around the entire galaxy ) 2. The necrons ( think killer robots but a little more nuance, these guys had transformed into killer robots and had a war with the old ones called “the war in heaven” this war was literally across the entire galaxy and its heavily implied that by the height of the necron dynasty they had control over most of the planets in the galaxy, so around billions of planets were under their control most likely ) 3. The eldar (they have a zealous reproductive cycle and so they heavily populated the galaxy, and once the necrons decided to go into sleep for countless eons, the eldar did infact have control over a very large portion of the galaxy though it’s kinda hard to pinpoint where they were at the height of their power) Overall my point is that while the imperium isn’t actually big warhammer gets pretty close with some of the older civilizations and you also have to take into account that there are serious threats that are impeding a lot of growth for any one species
My god. So much of what I appreciate about your level of thinking though time is surmised in this episode. Definitely need to watch this three times. At least.
You probably give the most tastful plugs out of any youtuber iv ever seen, its clear that you dont just take a random advertiser and as a die hard fan i really respect how you treat us Mr.Arthur. oh and of course yet another brillant talk, i love micheal so its always a pleasure when you have him on!
for those who like me tried it when it came out and actually really disliked it, version 2.0 has fixed it completely and is now MUCH better imho, so if you tried it and didn't like it give it another go.
Hey Isaac. Assuming that you achieved immortality and survived all the way to the iron star era as one of the oldest humans, and possibly anything else too, what do you think you would do with the last bit of power, having lived for so long and seen so much? (assuming that your personality is largely that of today)
By that time humans would evolve or be purposefully genetically altered to survive changing conditions. Some think we will eventually change ourselves to become intelligent self replicating robots... by purpose or accident... shedding our meat bag bodies as well as all the conditions needed to keep us alive now.
*ISAAC, your galactic colonization theories always remind me of my favorite anime ... LEGEND OF THE GALACTIC HEROES. Its about war and politics - on a galactic level. Every decision that is made affects billions of people on multiple worlds. If you've never watched it before, you really should - IT'S AWESOME !!!*
An Awesome Galactic Collaboration between my Favourite Sci-Fi Readers on the World Wide Web,... Isaac Arthur and John Michael Godier, It's great to see you both come together on this one, and it's clear that you both should do more in the near future,... Thank You,... To Both of You.
Best episode yet! Seriously, this episode nailed it with fun scenarios, mind-blowing statistics, and excellent music choice and graphics. I am BLOWN AWAY!
I've started tweaking the sci-fi setting I've been mulling over for years and I've recently tweaked the territorial claims of the factions to be based around a precursor portal network, with territorial claims set according to distances away from these portal nodes (which also function as FTL beacons) and the galactic core. I've also set on having three types of FTL: a "hyperspace" jump into a massless void of light (gravity fields translated as EM sources), alcubierre drive in real space and the nodes. Two weeks fixed travel time between two nodes and max. ~35 ly/d sustained travel time. Alcubierre drives cannot be steered and they build up a wake in front of them made of plasma and space debris, and the hyperspace drive offers no chance for a jumping ship to cool itself. So both drives require navigation and stopovers. After I redrew my galactic map, I noticed that a LOT of space will simply be claimed on paper, with only old member state territories, founding colony stellar neighbourhoods and the nodes themselves having any real sovereign hold. Drama could be had over instances where pre-existing territorial claims over particular stars or star clusters conflict with treaty-regulated borders. Such cases could also see enclaves of individual stars on different sides of the "border" or even planetary governments swearing allegiance to the other side. Perhaps even provincial governments.
+Erik Walker When it comes to thinking of astronomy as cartography, I'd liken the use of "cluster" as the same as "peninsula" on a map. Peninsulae can be anything from a natural harbor on a city's coastline to Florida, to Fennoscandia (and all its peninsulae) to the Balkans. Hell, Europe itself can be considered to be a peninsula on the Eurasian continent.
I would love to sit down with you and John, have a beer, and have a free flowing conversation about science/space. You guys are so incredibly intelligent, and interesting to listen to. You both are litterly the only two guys I allow for notifications for videos, and I go nuts in excitement every Thursday for your videos.
This is great! Its Arthursday!! I'm impressed by the quality of your weekly show.. It's always an interesting topic that is well thought out from many angles and expressed intelligently. Keep up the good work!!!
what about species that had no civilization until interaction with humans but arent "created", like maybe elephants and ravens and parrots and shit. I could imagine them gaining technologies from us but not being "uplifted" any more than we "uplift" kids when they copy us
Thank you for your great content. You have reinvigorated my love of sci fi, astronomy and futurism! Keep the videos coming. Also you and Mr. Godiers collaborations are great! Hope to see more!
Today I am one year subscriber in your channel. I was a subscriber at John michael’s channel 1st and these videos led me to the most amazing channel ever. Thank you for the great content and I hope we contact an alien civilization just to see your video about that
I agree. I almost always agree with Isaac's views of technology, and almost never with his views about humanity. But I agree, I couldn't find a nicer guy to disagree with.
One thing I got from this is that Continuity of data is a problem. It seems beneficial to create AI Observers that record and store information and history of any given planet we set foot on, or at least colonize, with durable black boxes just in case so even if the AI breaks down all the information is still hard written in a very long lasting core so even if locals forget how to read it, interstellar travelers from another region might still have that knowledge and learn the history of the area, and that's assuming the AI did break down. If it didn't, it could be a teacher and translator.
That could extend the amount of time until cultural divergence, but there would always eventually be a faction of people who might want to do things differently. I think that a truly unified galactic civilization isn't possible unless FTL travel exists, and not like 10 times light speed, but thousands of times light speed. I am sure that eventually we will figure it out.
Wouldn't it be practical for an expanding civilization to build and use Shkadov Thrusters to move their colonized systems closer together? Making your galaxy more compact would improve communication between solar systems and reduce divergence. I vaguely remember you mentioning in your video on that topic that the larger the star, the faster the stellar engine. Perhaps the largest stars could be used as shepherds for the smaller ones?
That assumes those colonies would want to keep close in the first place. Kinda like how the US wanted to keep the monarchist traditions of England.... oh wait.
But Dispersal is still a critical factor in Broader Survival (in a harsh and deadly universe, meaning clustering together is not a good survival strategy...
JMG and IA joining forces? So awesome!!!!!! I hope we'll treat colonization like we treat archaeology: leave plenty of untouched regions for future generations to handle better. In this instance, to allow for better studying of nature, and to allow for the natural evolution of life.
It is the Indian way (American, that is)... (meaning not to be rapacious with resources like Capitalism driven by greed) (which is itself only a symptom of continued universal human cluelessness) (enter me)...
I guess this video will remain relevant even after several millenniums. It is possible that if someone sitting in Andromeda galaxy 10k years from now, asks the question: "Top 10 videos from primitive humans that might still be relevant", this video might be in the Top 10. ;)
Lol! Anyone else notice how hard and obviously Mr. Godier was doing his best to talk much slower then he usually does😄👍I like it. I feel that is why his episodes are on the whole of 10 min. a piece. Loved the co-lab!!
John Michael Godier Love you man. I was like "oh wow a new JMG video, sick!" went to watch it... "It's part 2, part 2 of what?! Oh wow a collab with Isaac - made my day!!! But wait where's his video?" And now I'm here for part 1, will be popping over soon John! :D
It's not perfect but space engine can help get a glimpse of how ridiculously huge just even the local cluster is. Zooming around and looking at the speedometer really puts things into perspective.
Noman I completely agree. He even uses music feature in the game. The intro to this video is the beautiful Cosmic Soup. Why not use the visuals as well or at least more, as some scenes look like they are from Space Engine. I'd even universe sandbox 2, but the graphics aren't as good.
I always wondered about humanity’s fate if we were alone. We’d probably evolve and branch into several different species and then end up brutally warring with each other.
I'm not sure what hypothesis exactly you're referring to, but it sounds like one that can be waived away very easily. Survival as a species is always a constant struggle, an arms race against other species and our environments, and at the rate our species mutates and adapts we have so far survived many diseases and many natural dangers. And though we're all homo sapiens, there is plenty of genetic and phenetic variety among us, such as Himalayans and the Bajau having evolved lungs better suited to the low amounts of oxygen in the mountains and better eyesight for use during freediving, respectively. There's no need to fear evolution will catch up with us, especially not when we ourselves become the masters of the process within a century.
@Erik - LOL Now that's a lot of crazy. Considering that the human species is a young one compared to most, and we're approximately 10,000 generations into our current species, I have no idea why we'd suddenly be only 300 generations away from some kind of genetic doom. There are species out there that are surely more than a million generations old.
It seems more likely that aliens are talking via something other than radio waves. The problem is that our sensors aren’t good enough or even tuned to the right frequency that would allow us to pick their chatter up
Perhaps we are what the Preservers were to Star Trek, or, the Old Ones were to Warhammer 40K. We went into the universe and found no one. So we seeded life throughout the galaxy.
So does that mean we will possibly fuck up equally awfully as the Old ones, with the war in heaven, creating the orks and then some other nasties while being wiped out in our arrogance?
Before seeing this one, just a quick comment: The great fear of the Fermi Paradox is that the fact we see no one else out there means the engineering challenges of Being Out There, Doing Great Things, will prove insurmountable, and thus not in our future; we would be imprisoned in this star system by practical realities. So, just a quick prayer that We Are The Forerunners...
"Hey gurl, what say you and I breed at a ferocious rate?" XD We could always alter ourselves to be nymphomaniacs, that's a future I wouldn't mind living in honestly.
How old it will be doesn't factor into any probability calculations about what already has happened though. For that you'd only need to know how old it is relative to the relevant timescales of life and civilisation. If a type 3 civilisation arises on everage every 1 billion years per galactic supercluster it is quite old. If it is only once every 100 trillion years it's young.
It depends on how you look at it. It's very young if you take the heat death of the universe as your point of reference, or even just the end of the Stelliferous Era. Whether it is young or old for the purposes of life proliferating enough to be endemic to most parts of most galaxies, though, depends a lot on how common life is. If Earth is a typical case and most life in the universe arose at around the same time and life is also abundant, a few billion years is enough to reach full occupancy. If Earth is unusual, though, and it does seem to be, then we may indeed be very early to the party. A few hundred million years after Earth formed you might say Earth is still very young. If you're a just rock, though, you might be justified in saying it's very old already. After all, you've been going through the same rigmarole of being a rock on this planet for that whole time, and when you 'look' into the night sky you find that the universe is already full of rocks like you as far as you can see. ;)
life won't be possible in the universe for very long though. the stars will start dying out and stop replacing themselves or dramatically slow down in their production within too long. red dwarves will have more staying power but for various reasons likely aren't hospitable to life. there's only a tiny window within which life can exist in the universe.
Don't know what you mean by saying this, biological life and evolution will be viable for more time in the future than the current age of the universe.
@crippling autism Maybe not, I won't search the net now, but starting words may be "we just found the missing 90% baryonic matter"-basically, it's 90% of baryonic matter and it's in hot intergalactic H. So there is lots of H to make new stars, even with dark energy throwing us every which way, dark matter may use several 10's of % of that to make new stars.
It's a bit more like looking out your foggy bathroom window at night over a vast landscape from a very high mountain and not seeing any other lit windows or hearing anything out on that cold landscape at all. Just silent darkness. It's a bit odd given the vast timescales. The universe has been around for a while. But it is hardly conclusive evidence that nothing is alive and kicking or has never built any ringworlds out there ever. I remain hopeful. Even going out there and finding just the ancient bleached bones of dead civilizations would be amazing. Sad. Scary even. Amazing though.
no, the other way, look into your bathroom ,dont see anything living ,conclude there is no living thing inside the pipes? we are limited to 5 senses & a really awkard brain,,,
If a civilization had a warp drive system. Why would they want to travel the galaxy? Having a warp drive means the civilization has figured out how to bend and shape the very fabric of Space Time to their will. To my imagination having such technology gives almost limitless technology possibilities, and you use it to push a boat through a galaxy?
There might be valuable places to visit, like the highly energetic centers of galaxies or the cool intergalactic space and they might be too impatient to take the long voyage. But I agree such civilizations would have no reason to visit Earth.
This two-parter episode ASSUMES that faster_than_light travel is imposible (it is about "galactic colonization", not universe_conquering. Also: If "shaping the fabric of spacetime" is a posibility, then they will probably "sink" themselves into other dimensions/universes (leaving this one untouched), since "there" they can expand/live/explore better, much more interesting "stuff". -> This was addressed on one of the earlier videos for virtual realities.
Even if warp drive == complete mastery over time and space, there's no reason it wouldn't be put to boring, practical uses. We have thinking machines and control over electricity, but nobody's objecting to using those to drive cars around because there are "better uses" for the technology.
A civilization like that HAS to be either 1) Inherently divine by most definitions 2) Curious as _hell_. If they're gods, sure. That's a thing, then. But in the second case they'll do it out of simple curiousity. SFIA actually covered that at some point. So uh. They would. Simply due to their biological drive.
It depends on how the FTL system works. If it can take us to anywhere in the universe instantaneously, then we're probably looking at universal exploration and dominance. If it works like most sci-fi depictions and only shortens the traveling time, not eliminates it, then yes, staying within the galaxy is perfectly reasonable.
I think time is the factor that makes the most sense as a solution to the Fermi paradox. I don’t think that humans are the first intelligent species in the galaxy but rather might be the only one that currently exists or only one of a few that currently exists. There may have been many intelligent species in the history of our galaxy but they have gone extinct.
What if what we see happening with birth rates in humanity continues, and humanity never even reaches say 20 billion people, even thousands of years from now?
The main cause of plateauing birth rates is the lack of incentive and difficult of raising children. Birthrates may skyrocket again in the near future if child-bearing and parenting become more convenient. Vat-growing children will accomplish the same thing a magnitude faster.
The inconvenience of childcare is the only reason those other factors matter in population growth. If it was really convenient to raise children, where you got AI nannies, small work-loads, very affordable living standards, and didn't have to deal with pregnancy and child-birth, more women, and more men too, would be raising children. We don't have vat-grown children or AI-nannies, and most people have inflexible schedules. The popularity of working from home alone would bring birth-rates back up again, since the parent can raise a child with little interruption from their work. Today however, most people work in offices, factories, or travel a lot.
My guess is, in thousands of years the population will either be in the quadrillions or in the thousands. Living people will not need other living people to make them richer, happier or more safe. (Unlike all of human history before us.) They will no longer be contributors and will only be competitors for resources. So maybe we'll stop making them. I don't see why we wouldn't stop, tbh. OTOH maybe we will keep reproducing anyway. Idk why. Instinct probably won't be a factor at some point. (Or at least instinct will be optional and malleable.) But if there is still traditional reproduction, and some kinda space communism, then the population could get very large. (Unlimited.) I'd bet on fewer. Imagine all the material wealth of the solar system and the energy of the sun divided among 5,000 super-people. Now imagine the fuss if someone wanted to divide it among 5,000,000 - in other words to take 99.9% of everyone's wealth away. Even 5,001 people would cause a fuss.
If we never meet anyone out there.......... You have to ask why? It would be too amazing, too unbelievable, almost proof of a God with a HUGE sense of humour
Erik Walker I know what you are saying, the vast, almost incomprehensible nature of the cosmos, it like a machine, and the phrases" without shape or form & let there be light" seem be very significant
Using Hitchhikers Guide to the Galaxy logic, if god proves he exists, it goes against faith, and poof there goes god in puff of logic! "Oh that was easy!" -Man th-cam.com/video/-N5e1R4-G9I/w-d-xo.html
Isaac, just a quick note that i discover trying to watch your videos fast (big fan by the way), if you play them at 1.5x or 2x speed, your rhotacism become unnoticeable, just thought you should know if you didn't already, might be useful. Keep creating!
Great video again guys. As always some good food for thought. Couple things I have issues with: In regards to the Fermi Paradox: A lot of the Stars we are looking at in the night sky are 40, 50, 100, 300 light years away. Most are thousands of light years away. So we are looking at those stars as they appeared that many years ago. It’s like looking into the past. I know you guys know this, but it doesn’t appear that’s taken into account when looking for alien civilizations. We have taken immense strides in just the last 100 years and so much so that one could guess that we’ll be visiting all the planets of our solar system in another 100 years. So it takes about 200 years for a civilization to go from preindustrial to space-faring. So any of the Stars we can see may now be space-faring, but when we look at them, we are still seeing what they were like 200 years ago or more. It gets way worse for Stars that are thousands or tens of thousands of light years away. Every star out there might currently have space-faring civilizations but we’ll never detect them just because we are seeing them as they were in the past when they were not space-age societies. FTL travel and communication must be possible. We will find a way. We always find a way. That’s what we do as human beings. FTL communication will be done by some variation of entangled particle physics. Last time I checked, there are already three patents that have gone through and I, myself, am working on one right now that uses devices created out of entangled particles to communication across a distance instantaneously. It sound impossible right now with our current technology, but someone will figure it out. It’s just a matter of time. This FTL communication also ties into the Fermi Paradox. The reason there aren’t a ton of communication channels flooding the galaxy is because everyone figures out FTL communication and radio and any other broadcast technology is no longer needed. FTL travel. This is something I have no idea on and cannot even speculate on at the moment, but I am confident that we humans will figure it out. Just like every other impossible roadblock that has ever been put in front of us. It’s just the nature of humankind to break down any barrier to exploration that is out in front of us. Thank again guys and keep the collaborations coming!
Oh yeah -and also wanted to reiterate one of my earlier comments on one of the previous videos. Nothing in nature happens just once. Fermi Paradox suggests we may be the only intelligent life out there, since we don’t see evidence of any others. But nothing happens just once in any set of data with enough data points to count into the trillions of billions as in the amount of stars in our galaxy, let alone the universe. If you have trillions of billions of data points (stars) then the chance of getting a zero result is far greater than a chance of having a one result. Since we know that we exist (we’re here, I’m typing this and everyone else is residing this) and we know that there cannot be a result of one, then we know that logically there must be more civilizations out there in the galaxy and the universe.
No, not natural, but nothing scientific happens just once. We need to be able to reproduce the experiment in order to call it science. Examples: -as far as I know every uranium atom that has split has done it exactly once, it takes a lot of effort and outside energy not to mention very high tech to reassemble that atom -I will type this answer exactly one time -you will not need more examples, right ? -human civilization happens only once (probably, dismissing multiple worlds/endless universe/time reversal and some more here) Are those not natural events ? Even if you bring statistics it's not probable someone else will write this answer. Except they will copy/paste it if I know anything about internet...
You can watch Part 2 at: th-cam.com/video/tbvmxo90F9I/w-d-xo.html
Keep it up! IMO you are on your way to being the next Carl Sagan IMO!
VR CO VDO
Wheeew more on Fermi Paradox! There shouldn't be an end to those episodes
Keep up the great quality!!! I follow you since 1 year and when i watched your first vid i legit thought its an uploaded documentation from the discovery channel or something like that. I love how much work you put into these videos and you really got me into futurism
Dude I'm making furries a real thing aka humans mixed with animal DNA and androids that can have babies.

Run as you may, there are no places in the galaxy where you can escape the mighty paper clip optimizer.
If Clippy turns out to be the final key to extraterrestrial communications, I'm going to go live in VR.
That is exactly what I first thought when Isaac mentioned it. Paper Clips!
Intergalactic domination is not only possible, but inevitable assuming there are no Klingons or Romulans to challenge our ascent!
Bah we'll kick their asses!
Terra Invictus!
well if they're a prick, set phasers to stun; if they're all cactuses (cacti?), set phasers to kill
Just take all the spice and don't give them any.
I'd rather meet the Vorlon
Then we just purge the xenos and move on.
I'm so very excited for this collaboration with JMG. Isaac, and JMG are by far, and away my favorite you tubers. Thank you so much for the fantastic content you guys, and your teams provide us with!
I’m do glad to hear you address the inevitable divergence and diversity inherent in colonizing a galaxy! Of course I never would have expected less from your channel, but it does bother me as a biologist how most sci-fi doesn’t address it. Even when there are older civilizations they tend to be somewhat homogenous and their members are archetypal.
It was the year 12042. The immortal Isaac Arthur was on vacation on Zchri+Ar9qyn - a newly colonized planet in the Sagittarius Arm. After unpacking in the hotel, he decided to go to the hotel bar to have a drink. In there, he saw a woman sitting lonely at a table with a cup of some pink liquid in her pedipalp. Curious, he asked the bartender for the same stuff. He sat down, greeted her and took the sip from the cup. He gagged and spat on the floor. The liquid was cold (even though steaming), sticky and sour. What's worse, something flapped on his tongue like a fish when he had it in his mouth. The woman chuckled. "Have you never drunk coffee before?", she asked flirtatiously.
What
Nethan2000 cool story you should be a novel writer
*Perfection*
That transition to Godier was so smooth. Nice editing. I heard the twist in voice and the unique absence of the speech condition, and I was like "Oh, that's right, collaboration."
Great video. As quality as your videos ever were.
Always cool to see 2 of your favourite channels collaborate.
Fist like
Amen
I love how fantastic and imagnitive these videos are. The angry dolphin was simply genius!
My girlfriend and I always play your videos at night when we're going to sleep. "Wanna put on some wascally wabbit?" "Yep"
Always interesting and relaxing. Thanks and keep it up!
Oh yes, another two parter. And I just leave random comments even if they are not well tought, just so the algorithm favors spreading this channel
Lukegear part two is up!
Praise be to The Algorithm!
Ali Beli, a Michael Rosen reference?
Hunter Holly, not really, but at this point, after watching a few youtube people sharing their experiences and research, as well as bunch of analytics, I think we have pretty solid grasp of what the algorithm is promoting
All hail the algorithm!
... lets uplift racoons now. Theyre adorable. :3
...
and a talking tree...
And they have hands
I shit you not , SFIA is miles better than anything on Discovery science (Yes, even better than Through the Wormhole)
The only thing that comes close is Nat Geo's C O S M O S
The Cosmos remake is a fucking joke.
Nothing comes close to Carl Sagan's Cosmos,nothing ever will.Mr.Arthur's content is brilliant possibly the best on youtube,but the original Cosmos towers over all.
I go back to the original cosmos series from time to time, some of my children are still quite young and we listen to it on Sunday. I have made posts on those videos referring people to this page. Hopefully that helps spread the word. S.F.I.A.
Faint praise lol.
Twirlip Of The Mists Please elaborate.
christ, id love to see a writer actually tackle the gargantuan size and diversity of a true K2 civ.
Though not true K2 level, Banks culture novels handled the scope and diversity of advanced galaxy spanning civilizations as well as one can expect before you probably start to lose reader engagement and emotional involvement...
Orion's Arm. Its an open source online thing so its rather hodge podge but it certainly has the scale down.
Not even Warhammer 40k, despite all of it's bragging fanboys, gets it right. I mean, the Imperium of Man being a galaxy-wide power while it has only 1 million worlds? Utterly laughable. There are an estimated 8.8 billion potentially habitable worlds in the galaxy. 1 million literally isn't even 1% of that. It's more like 1/6 of 1%, and that's erring on generous. A galaxy-spanning civilization is required to have at least hundreds of millions of inhabited planets or its not even worth referring to as "galaxy-spanning".
Joel Gawne from my knowledge of the 40k universe, the 1 million worlds are actually spread across the entire galaxy ( because the way they travel is inconsistent and leads to them accidentally Landing in another galactic quadrant sometimes) so while they may not even be close to the total habitable planets, these planets do in fact span the galaxy however one important thing to note is that the Imperium of man is fighting dozens upon dozens of existential threats and at the same time are destroying the entire surfaces of planets and sending billions (trillions depending) to their deaths almost on a weekly if not daily basis, so if we are to take away those factors the Imperium may very well have been a true galactic empire where they have colonized most of the habitable planets instead Of literally fighting enemies that are practical gods.
Also you are forgetting 3 major factions that may very have colonized most of the galaxy.
1. The old ones (these were believed to be the first to create civilization and mastered practically everything and were living around the entire galaxy )
2. The necrons ( think killer robots but a little more nuance, these guys had transformed into killer robots and had a war with the old ones called “the war in heaven” this war was literally across the entire galaxy and its heavily implied that by the height of the necron dynasty they had control over most of the planets in the galaxy, so around billions of planets were under their control most likely )
3. The eldar (they have a zealous reproductive cycle and so they heavily populated the galaxy, and once the necrons decided to go into sleep for countless eons, the eldar did infact have control over a very large portion of the galaxy though it’s kinda hard to pinpoint where they were at the height of their power)
Overall my point is that while the imperium isn’t actually big warhammer gets pretty close with some of the older civilizations and you also have to take into account that there are serious threats that are impeding a lot of growth for any one species
It'd be cool in fiction but I'm skeptical that its even possible on a practical level. Also Warhammer 40Ks Tyranids seem to be a K2 civ.
My god. So much of what I appreciate about your level of thinking though time is surmised in this episode. Definitely need to watch this three times. At least.
Happy Arthursday. Love from Jamaica!
You probably give the most tastful plugs out of any youtuber iv ever seen, its clear that you dont just take a random advertiser and as a die hard fan i really respect how you treat us Mr.Arthur. oh and of course yet another brillant talk, i love micheal so its always a pleasure when you have him on!
Listening to this while playing Stellaris
One of the best things to do while playing that game.
Haha, same here... Also the sun is up. (Paradox games and Civ 2 players know what I'm talking about).
for those who like me tried it when it came out and actually really disliked it, version 2.0 has fixed it completely and is now MUCH better imho, so if you tried it and didn't like it give it another go.
version 2.0 hyperlane only its not really space anymore.
Space Engine here.
Hey Isaac. Assuming that you achieved immortality and survived all the way to the iron star era as one of the oldest humans, and possibly anything else too, what do you think you would do with the last bit of power, having lived for so long and seen so much?
(assuming that your personality is largely that of today)
Nazamroth I will become a god.
He would probably use the last bit of power to make coffee for himself.
By that time humans would evolve or be purposefully genetically altered to survive changing conditions. Some think we will eventually change ourselves to become intelligent self replicating robots... by purpose or accident... shedding our meat bag bodies as well as all the conditions needed to keep us alive now.
Maybe power some super tech
*ISAAC, your galactic colonization theories always remind me of my favorite anime ... LEGEND OF THE GALACTIC HEROES. Its about war and politics - on a galactic level. Every decision that is made affects billions of people on multiple worlds. If you've never watched it before, you really should - IT'S AWESOME !!!*
I love that show. I'm sure Isaac would love the books.
I love how thoughtful and imaginitive you guys are. Videos like this are as enjoyable as any science fiction.
humanity the only bulwark against the horrors of non-existence that we know of.
live footage of my face Yes, I agree.
An Awesome Galactic Collaboration between my Favourite Sci-Fi Readers on the World Wide Web,... Isaac Arthur and John Michael Godier, It's great to see you both come together on this one, and it's clear that you both should do more in the near future,... Thank You,... To Both of You.
This was likely the best explanation of how big the galaxy is that I have ever heard
Best episode yet! Seriously, this episode nailed it with fun scenarios, mind-blowing statistics, and excellent music choice and graphics. I am BLOWN AWAY!
Another great collaboration from my two favorite space vloggers. Thanks!
I've started tweaking the sci-fi setting I've been mulling over for years and I've recently tweaked the territorial claims of the factions to be based around a precursor portal network, with territorial claims set according to distances away from these portal nodes (which also function as FTL beacons) and the galactic core. I've also set on having three types of FTL: a "hyperspace" jump into a massless void of light (gravity fields translated as EM sources), alcubierre drive in real space and the nodes. Two weeks fixed travel time between two nodes and max. ~35 ly/d sustained travel time. Alcubierre drives cannot be steered and they build up a wake in front of them made of plasma and space debris, and the hyperspace drive offers no chance for a jumping ship to cool itself. So both drives require navigation and stopovers.
After I redrew my galactic map, I noticed that a LOT of space will simply be claimed on paper, with only old member state territories, founding colony stellar neighbourhoods and the nodes themselves having any real sovereign hold.
Drama could be had over instances where pre-existing territorial claims over particular stars or star clusters conflict with treaty-regulated borders. Such cases could also see enclaves of individual stars on different sides of the "border" or even planetary governments swearing allegiance to the other side. Perhaps even provincial governments.
+Erik Walker
When it comes to thinking of astronomy as cartography, I'd liken the use of "cluster" as the same as "peninsula" on a map. Peninsulae can be anything from a natural harbor on a city's coastline to Florida, to Fennoscandia (and all its peninsulae) to the Balkans. Hell, Europe itself can be considered to be a peninsula on the Eurasian continent.
I would love to sit down with you and John, have a beer, and have a free flowing conversation about science/space. You guys are so incredibly intelligent, and interesting to listen to. You both are litterly the only two guys I allow for notifications for videos, and I go nuts in excitement every Thursday for your videos.
Today's my birthday! Thank you for the awesome birthday gift Issac Arthur & everyone else who worked on this video.
Great video !
This is great! Its Arthursday!! I'm impressed by the quality of your weekly show.. It's always an interesting topic that is well thought out from many angles and expressed intelligently. Keep up the good work!!!
Happy Arthursday everyone!!
ebigunso it will never get old!
This is why I like the City under the stars.
The story that takes place One billion years in the future.Arthur C. Clark was a genius.
I heard the intro, my first thought was "The Foundation from Asimov", you know, with the Galactic Empire ?
playwars Exactly, me too
That was one of your best videos ever! Mind blown!
In my fiction, the primary government defines humans as "homo sapiens and all descendents, subspecies, and created sentients, organic or inorganic."
what about species that had no civilization until interaction with humans but arent "created", like maybe elephants and ravens and parrots and shit. I could imagine them gaining technologies from us but not being "uplifted" any more than we "uplift" kids when they copy us
that don't make no sense, humans are either oganisms of the species homo sapiens or of the genus homo.
Thank you for your great content. You have reinvigorated my love of sci fi, astronomy and futurism! Keep the videos coming. Also you and Mr. Godiers collaborations are great! Hope to see more!
Thank you Isaac for another thought provoking video!
Today I am one year subscriber in your channel. I was a subscriber at John michael’s channel 1st and these videos led me to the most amazing channel ever. Thank you for the great content and I hope we contact an alien civilization just to see your video about that
I may not agree with your answer to the Fermi Paradox, but I can't think of nicer guys to have opposing viewpoints :)
Right? These are just opinions and nothing else. Entertaining and cheap because you can watch it on a laptop.
I agree. I almost always agree with Isaac's views of technology, and almost never with his views about humanity. But I agree, I couldn't find a nicer guy to disagree with.
Steady on old chap.
I don't believe there's paradox at all. We're simply ignorant of the universe at large. That's not a paradox.
Why do you disagree?
The music in your videos always has great atmosphere. Love it
Why didn't this appear when it was uploaded
Nice one. I like how you keep reminding us to think bigger.
One thing I got from this is that Continuity of data is a problem. It seems beneficial to create AI Observers that record and store information and history of any given planet we set foot on, or at least colonize, with durable black boxes just in case so even if the AI breaks down all the information is still hard written in a very long lasting core so even if locals forget how to read it, interstellar travelers from another region might still have that knowledge and learn the history of the area, and that's assuming the AI did break down. If it didn't, it could be a teacher and translator.
That could extend the amount of time until cultural divergence, but there would always eventually be a faction of people who might want to do things differently. I think that a truly unified galactic civilization isn't possible unless FTL travel exists, and not like 10 times light speed, but thousands of times light speed. I am sure that eventually we will figure it out.
You two have inspired me to start writing my own SF, introduced me to new authors and given me a little more hope in humanity...Thank you.
I knew it! Fraser is an alien!
Great work as always Isaac!
Wouldn't it be practical for an expanding civilization to build and use Shkadov Thrusters to move their colonized systems closer together? Making your galaxy more compact would improve communication between solar systems and reduce divergence.
I vaguely remember you mentioning in your video on that topic that the larger the star, the faster the stellar engine. Perhaps the largest stars could be used as shepherds for the smaller ones?
That assumes those colonies would want to keep close in the first place. Kinda like how the US wanted to keep the monarchist traditions of England.... oh wait.
But Dispersal is still a critical factor in Broader Survival (in a harsh and deadly universe, meaning clustering together is not a good survival strategy...
Another awesome experience dropped by none other than the incomparable, Issac Arthur.
Write.
A.
Book.
Please.
I would buy the hell out of it
How the heck have I not listened to this episode. Nice duo the both of you!
Ah two notifications from my two favourite super-geeks ;)
We must secure the existence...
Thanks for uploading, Isaac! There’s a pretty big storm about to hit, so I’ll have extra time to watch!
You know what would be fun? Placing every IA video in an approximate chronological order, all the way up to the CATEOT series
JMG and IA joining forces? So awesome!!!!!!
I hope we'll treat colonization like we treat archaeology: leave plenty of untouched regions for future generations to handle better. In this instance, to allow for better studying of nature, and to allow for the natural evolution of life.
It is the Indian way (American, that is)... (meaning not to be rapacious with resources like Capitalism driven by greed) (which is itself only a symptom of continued universal human cluelessness) (enter me)...
Welcome to arthursday ladies and gents! Grab your drink, grab your snack, and settle in!
let's not forget the coffee ;)
You have a great series and thanks for letting us know about Michael Godier.
I guess this video will remain relevant even after several millenniums. It is possible that if someone sitting in Andromeda galaxy 10k years from now, asks the question: "Top 10 videos from primitive humans that might still be relevant", this video might be in the Top 10. ;)
I'm really sorry for this in advance, but *millennia
Abhishek Garg That will interesting.
Abhishek Garg
2018: whre are the aliens?
10k years later : 1000degree knife challange on blackhole of the center of the galaxy
top 10s shall outlive humanity itself...
Only recently subscribed but I am devouring your presentations. Excellent stuff.
And I can understand you just fine.
It's Arthursday bois!
Lol! Anyone else notice how hard and obviously Mr. Godier was doing his best to talk much slower then he usually does😄👍I like it. I feel that is why his episodes are on the whole of 10 min. a piece. Loved the co-lab!!
Wtf?! I didn't get the notification! John's came up but, not yours.
Same here.
Alien conspiracy ;)
No alien conspiracy, just me messing up the release timing.
John Michael Godier Love you man. I was like "oh wow a new JMG video, sick!" went to watch it... "It's part 2, part 2 of what?! Oh wow a collab with Isaac - made my day!!! But wait where's his video?"
And now I'm here for part 1, will be popping over soon John! :D
Not that I'm complaining... We get a 2 parter today! Been going through withdrawal. lol
It's not perfect but space engine can help get a glimpse of how ridiculously huge just even the local cluster is. Zooming around and looking at the speedometer really puts things into perspective.
Noman I completely agree. He even uses music feature in the game. The intro to this video is the beautiful Cosmic Soup. Why not use the visuals as well or at least more, as some scenes look like they are from Space Engine. I'd even universe sandbox 2, but the graphics aren't as good.
I always wondered about humanity’s fate if we were alone. We’d probably evolve and branch into several different species and then end up brutally warring with each other.
I'm not sure what hypothesis exactly you're referring to, but it sounds like one that can be waived away very easily. Survival as a species is always a constant struggle, an arms race against other species and our environments, and at the rate our species mutates and adapts we have so far survived many diseases and many natural dangers. And though we're all homo sapiens, there is plenty of genetic and phenetic variety among us, such as Himalayans and the Bajau having evolved lungs better suited to the low amounts of oxygen in the mountains and better eyesight for use during freediving, respectively. There's no need to fear evolution will catch up with us, especially not when we ourselves become the masters of the process within a century.
agree
@Erik - LOL
Now that's a lot of crazy. Considering that the human species is a young one compared to most, and we're approximately 10,000 generations into our current species, I have no idea why we'd suddenly be only 300 generations away from some kind of genetic doom. There are species out there that are surely more than a million generations old.
The future is so scary and that's what it makes it so enticing to even get a tiny spec of what it will look like in our lifetime.
Semper Fi Arthur!
Great stuff as always, thanks Isaac!
Video moral;
"People are weird and complicated, including people we kind of create"
Ryukachoo true
It seems more likely that aliens are talking via something other than radio waves. The problem is that our sensors aren’t good enough or even tuned to the right frequency that would allow us to pick their chatter up
Perhaps we are what the Preservers were to Star Trek, or, the Old Ones were to Warhammer 40K. We went into the universe and found no one. So we seeded life throughout the galaxy.
So does that mean we will possibly fuck up equally awfully as the Old ones, with the war in heaven, creating the orks and then some other nasties while being wiped out in our arrogance?
Z Zs Maybe
wicksinn That will be cool.
+Z “Muzolf” Zs Fucking lok at us. Id be suprised if we didnt fuck up WORSE.
WE are the precursor civilization. That's a pretty sobering thought.
Before seeing this one, just a quick comment:
The great fear of the Fermi Paradox is that the fact we see no one else out there means the engineering challenges of Being Out There, Doing Great Things, will prove insurmountable, and thus not in our future; we would be imprisoned in this star system by practical realities.
So, just a quick prayer that We Are The Forerunners...
"Breeding at a ferocious rate" - Isaac Arthur
TovenOvideoRPC ok
Bweeding at a fewocious wate.
"Hey gurl, what say you and I breed at a ferocious rate?"
XD
We could always alter ourselves to be nymphomaniacs, that's a future I wouldn't mind living in honestly.
3:04 "is quite rare." Great 'R' sound there, looks like those speech classes are paying off. Congrats!
Ah, 26 minutes and 8 seconds of bliss ..
Superb. Such an intriguing concept. So many avenues
Considering the age our universe may achieve, it seems a 14 bi yo universe is a pretty young universe. Finally someone said it.
How old it will be doesn't factor into any probability calculations about what already has happened though. For that you'd only need to know how old it is relative to the relevant timescales of life and civilisation. If a type 3 civilisation arises on everage every 1 billion years per galactic supercluster it is quite old. If it is only once every 100 trillion years it's young.
It depends on how you look at it. It's very young if you take the heat death of the universe as your point of reference, or even just the end of the Stelliferous Era. Whether it is young or old for the purposes of life proliferating enough to be endemic to most parts of most galaxies, though, depends a lot on how common life is. If Earth is a typical case and most life in the universe arose at around the same time and life is also abundant, a few billion years is enough to reach full occupancy. If Earth is unusual, though, and it does seem to be, then we may indeed be very early to the party.
A few hundred million years after Earth formed you might say Earth is still very young. If you're a just rock, though, you might be justified in saying it's very old already. After all, you've been going through the same rigmarole of being a rock on this planet for that whole time, and when you 'look' into the night sky you find that the universe is already full of rocks like you as far as you can see. ;)
life won't be possible in the universe for very long though. the stars will start dying out and stop replacing themselves or dramatically slow down in their production within too long. red dwarves will have more staying power but for various reasons likely aren't hospitable to life. there's only a tiny window within which life can exist in the universe.
Don't know what you mean by saying this, biological life and evolution will be viable for more time in the future than the current age of the universe.
@crippling autism Maybe not, I won't search the net now, but starting words may be "we just found the missing 90% baryonic matter"-basically, it's 90% of baryonic matter and it's in hot intergalactic H. So there is lots of H to make new stars, even with dark energy throwing us every which way, dark matter may use several 10's of % of that to make new stars.
excellent collaboration so glad to see you guys working together - best video ever
First to this comment section. Just like humanity to the Milky Way.
Isaac Arthur, John Michael Godier, Joe Scott
The holy trinity of futurism on youtube.
The Fermi Paradox: look out your window, don't see anyone on the street, conclude no one is living in your neighborhood.
Sorry, but I don‘t think you thought this quite through.
Is the existance of a street not a clear indicator of other life?
xassix we've picked up other Earth like planets though
It's a bit more like looking out your foggy bathroom window at night over a vast landscape from a very high mountain and not seeing any other lit windows or hearing anything out on that cold landscape at all. Just silent darkness. It's a bit odd given the vast timescales. The universe has been around for a while. But it is hardly conclusive evidence that nothing is alive and kicking or has never built any ringworlds out there ever. I remain hopeful. Even going out there and finding just the ancient bleached bones of dead civilizations would be amazing. Sad. Scary even. Amazing though.
It’s looking out your window and not seeing any artificial lights on your continent.
no, the other way, look into your bathroom ,dont see anything living ,conclude there is no living thing inside the pipes?
we are limited to 5 senses & a really awkard brain,,,
IA + JMG = epic quality.
If a civilization had a warp drive system. Why would they want to travel the galaxy? Having a warp drive means the civilization has figured out how to bend and shape the very fabric of Space Time to their will. To my imagination having such technology gives almost limitless technology possibilities, and you use it to push a boat through a galaxy?
There might be valuable places to visit, like the highly energetic centers of galaxies or the cool intergalactic space and they might be too impatient to take the long voyage. But I agree such civilizations would have no reason to visit Earth.
This two-parter episode ASSUMES that faster_than_light travel is imposible (it is about "galactic colonization", not universe_conquering.
Also: If "shaping the fabric of spacetime" is a posibility, then they will probably "sink" themselves into other dimensions/universes (leaving this one untouched), since "there" they can expand/live/explore better, much more interesting "stuff".
-> This was addressed on one of the earlier videos for virtual realities.
Even if warp drive == complete mastery over time and space, there's no reason it wouldn't be put to boring, practical uses. We have thinking machines and control over electricity, but nobody's objecting to using those to drive cars around because there are "better uses" for the technology.
A civilization like that HAS to be either
1) Inherently divine by most definitions
2) Curious as _hell_.
If they're gods, sure. That's a thing, then. But in the second case they'll do it out of simple curiousity. SFIA actually covered that at some point.
So uh. They would. Simply due to their biological drive.
It depends on how the FTL system works. If it can take us to anywhere in the universe instantaneously, then we're probably looking at universal exploration and dominance. If it works like most sci-fi depictions and only shortens the traveling time, not eliminates it, then yes, staying within the galaxy is perfectly reasonable.
I think time is the factor that makes the most sense as a solution to the Fermi paradox. I don’t think that humans are the first intelligent species in the galaxy but rather might be the only one that currently exists or only one of a few that currently exists. There may have been many intelligent species in the history of our galaxy but they have gone extinct.
What if what we see happening with birth rates in humanity continues, and humanity never even reaches say 20 billion people, even thousands of years from now?
The main cause of plateauing birth rates is the lack of incentive and difficult of raising children. Birthrates may skyrocket again in the near future if child-bearing and parenting become more convenient. Vat-growing children will accomplish the same thing a magnitude faster.
Melon Lord the plateauing of birthrates is correlated with increased education of women, job opportunities for women, and access to birth control.
Melon Lord LOL. It has never been easier, safer, more affordable or more convenient to reproduce than it is today.
The inconvenience of childcare is the only reason those other factors matter in population growth. If it was really convenient to raise children, where you got AI nannies, small work-loads, very affordable living standards, and didn't have to deal with pregnancy and child-birth, more women, and more men too, would be raising children. We don't have vat-grown children or AI-nannies, and most people have inflexible schedules.
The popularity of working from home alone would bring birth-rates back up again, since the parent can raise a child with little interruption from their work. Today however, most people work in offices, factories, or travel a lot.
My guess is, in thousands of years the population will either be in the quadrillions or in the thousands.
Living people will not need other living people to make them richer, happier or more safe. (Unlike all of human history before us.) They will no longer be contributors and will only be competitors for resources. So maybe we'll stop making them. I don't see why we wouldn't stop, tbh.
OTOH maybe we will keep reproducing anyway. Idk why. Instinct probably won't be a factor at some point. (Or at least instinct will be optional and malleable.) But if there is still traditional reproduction, and some kinda space communism, then the population could get very large. (Unlimited.)
I'd bet on fewer. Imagine all the material wealth of the solar system and the energy of the sun divided among 5,000 super-people. Now imagine the fuss if someone wanted to divide it among 5,000,000 - in other words to take 99.9% of everyone's wealth away. Even 5,001 people would cause a fuss.
been waiting on this team up... great work guys
dam am late to the class
Ohhhh Yeaaaah! Just pulled down the notification bar and saw this there...
It's Arthursday everyone! :D
Am I the only Girl who likes Isaac Arthur videos?
EverlastingSky probably not
yes. it is so.
answer unclear ask again later
No
It would be rather depressing yet unlikely if you are.
Love both your channels.
If we never meet anyone out there.......... You have to ask why? It would be too amazing, too unbelievable, almost proof of a God with a HUGE sense of humour
Erik Walker Or there could be actual evidence for God's existence.
Erik Walker I know what you are saying, the vast, almost incomprehensible nature of the cosmos, it like a machine, and the phrases" without shape or form & let there be light" seem be very significant
I am god. Worship me.
Using Hitchhikers Guide to the Galaxy logic, if god proves he exists, it goes against faith, and poof there goes god in puff of logic! "Oh that was easy!" -Man
th-cam.com/video/-N5e1R4-G9I/w-d-xo.html
We *are* the Timelords!
For all we know we were once a galactic civilization that collapsed and we are merely the remnants.
Because of this channel, Thursday is my favorite week day.
It’s so cool to hear you guys working on the same narrative. 👍
"We are either the first civilization in the universe, or the last, both are equally terrifying." - Forgot who said this
ive been subscribed to both channels for quite a while now, and i especially like this topic.. TODAY IS A GREAT DAY XD
So a colab between Isaac Arthur and John Michel Godier? Better grab a beer and strap myself in.
Your voice is very relaxing and easy to fall asleep to.
Isaac, just a quick note that i discover trying to watch your videos fast (big fan by the way), if you play them at 1.5x or 2x speed, your rhotacism become unnoticeable, just thought you should know if you didn't already, might be useful. Keep creating!
You two have inspired me to start writing my own SF, introduced me to new authors and given me a little more hope in humanity...Thank you.
Great video again guys. As always some good food for thought.
Couple things I have issues with:
In regards to the Fermi Paradox: A lot of the Stars we are looking at in the night sky are 40, 50, 100, 300 light years away. Most are thousands of light years away. So we are looking at those stars as they appeared that many years ago. It’s like looking into the past. I know you guys know this, but it doesn’t appear that’s taken into account when looking for alien civilizations. We have taken immense strides in just the last 100 years and so much so that one could guess that we’ll be visiting all the planets of our solar system in another 100 years. So it takes about 200 years for a civilization to go from preindustrial to space-faring. So any of the Stars we can see may now be space-faring, but when we look at them, we are still seeing what they were like 200 years ago or more. It gets way worse for Stars that are thousands or tens of thousands of light years away. Every star out there might currently have space-faring civilizations but we’ll never detect them just because we are seeing them as they were in the past when they were not space-age societies.
FTL travel and communication must be possible. We will find a way. We always find a way. That’s what we do as human beings. FTL communication will be done by some variation of entangled particle physics. Last time I checked, there are already three patents that have gone through and I, myself, am working on one right now that uses devices created out of entangled particles to communication across a distance instantaneously. It sound impossible right now with our current technology, but someone will figure it out. It’s just a matter of time. This FTL communication also ties into the Fermi Paradox. The reason there aren’t a ton of communication channels flooding the galaxy is because everyone figures out FTL communication and radio and any other broadcast technology is no longer needed.
FTL travel. This is something I have no idea on and cannot even speculate on at the moment, but I am confident that we humans will figure it out. Just like every other impossible roadblock that has ever been put in front of us. It’s just the nature of humankind to break down any barrier to exploration that is out in front of us.
Thank again guys and keep the collaborations coming!
Oh yeah -and also wanted to reiterate one of my earlier comments on one of the previous videos.
Nothing in nature happens just once. Fermi Paradox suggests we may be the only intelligent life out there, since we don’t see evidence of any others. But nothing happens just once in any set of data with enough data points to count into the trillions of billions as in the amount of stars in our galaxy, let alone the universe.
If you have trillions of billions of data points (stars) then the chance of getting a zero result is far greater than a chance of having a one result. Since we know that we exist (we’re here, I’m typing this and everyone else is residing this) and we know that there cannot be a result of one, then we know that logically there must be more civilizations out there in the galaxy and the universe.
No, not natural, but nothing scientific happens just once. We need to be able to reproduce the experiment in order to call it science.
Examples:
-as far as I know every uranium atom that has split has done it exactly once, it takes a lot of effort and outside energy not to mention very high tech to reassemble that atom
-I will type this answer exactly one time
-you will not need more examples, right ?
-human civilization happens only once (probably, dismissing multiple worlds/endless universe/time reversal and some more here)
Are those not natural events ? Even if you bring statistics it's not probable someone else will write this answer. Except they will copy/paste it if I know anything about internet...
