Yeah I’m sure they would show up, thank them for their efforts, and take them to the new planet. Surely they could find their location- all very predictable math. They would be incredibly curious what happened to those first travelers too.
I don't know why TH-cam keeps insisting on notifying you guys with the file name I uploaded instead of the actual title that I gave the video on the site. Just so ya'll are aware, the actual title that should be showing up is "The Big Problem With Interstellar Travel" and not Landlocked Navies 2 lol.
When I was a kid, the fastest spacecraft would take 42000 years to reach Proxima. Now it only takes 19000 years. We've already cut it more than in half.
@Sahil Ali Of course it is, but that's not the point. Each time a scientific advancement is made, it makes the time necessary for travel that much more shorter. Which in turn makes everything that much "closer" to us. 150 years ago, it used to take an entire summer, risking your life, just to make it to the west coast. Now it's a 5 hr flight. We used science to figure out ever faster methods of travel on our planet and we will do the same in space. It all depends on how badly we want to get there.
@Hdye Hdhde I see your point, but like I said it all depends on how badly we want to get there. When the United States wanted to build a nuclear device, they gathered up the best and the brightest scientists, put them all in a secret location and had one operational in 3 years. Money is probably the biggest barrier. R&D is a notoriously expensive operation. On top of that you need the right people. And just to make it a little bit more of a pain in the ass, they also have to obey certain legal restrictions, as well as International treaties that ban certain materials or activities in space. Now, if there was a rich philanthropist that wanted to undertake it as a pet project along with other entities, kind of what like Elon Musk is doing with Mars missions, then maybe public interest would peak enough, to have something come together.
Etienne Aubert well what if it always stays like that? What if in 10000 years we still would need 19‘000 years should humanity never leave the solar system?
Then there is the counter problem... waiting too long. We're assuming that the modern advanced civilization we enjoy today will at least last forever and probably get even better. There is nothing preventing humanity's extinction or slipping into a more primitive state. Maybe anti-vaxxers and flat-Earthers become the rulers and throw out modern technology. Or climate change breaks civilization. Or fossil fuels run out before we have decent alternatives. Something happens and humanity loses the ability or interest to go to space.
@@CarFreeSegnitz Humanity will continue to advance no matter what. I am sure in times of great crises people would always thought that it was trully the end of the world. But guess what. All of these passed and we still go on.
I'd say if it can take at least within a human life span or 2 would be probably feasible, but I do believe that we could do it within the human lifespan.
I mean.. unless the new technology involves wormholes or some esoteric things which would make them get there instantly... But still, I see now reason why the original ship would be incommunicable...
Exactly. This whole idea seems so dumb. Why can't they pick them up on the way? There would be outrage if we just left them out there to die. Scientists would work hard to create a rescue mission.
Yeah, it's just a thought experiment though. But the problem would really be apparent at higher speeds. Let's say we could instead travel a bit under 1% of the speed of light. Sure, you could slow down to catch up, it would take the ship over ~1300-1500 years to get to Proxima Centuari if you let it coast there otherwise. But the fuel requirements needed to slow down your ship to match the velocity, and then speed back up again would be brutal on your fuel reserves. And you still need to slow down at Proxima Centuari! Which is why it's still better to wait. If we got a drive capable of travelling at 5% of the speed of light in 200 years, and then it takes us 100 years to build a ship, and then it takes 90 years to get there with that drive, that's still (at least) almost a thousand years faster than if you went early.
yes but you still have all the knowlage we have in Earth because we will send them with the guide that tells them the phisic laws and how to colonize a planet and it will also say your ship has limited resources so you HAVE TO colonize a planet over there. And say it would be cool to send a letter after you arived there because we are courious what you have done
@@ThebelieverMtiz well we kinda know what a human few genarations before us looks like and even somewhat know what our ancestors millons of generations before even if calling them human would be very misleading and can make a reasonable guesses abouth our billons of genarations before ancestors so i don't think we are that bad. Also there is technology exists now so this ship wouldn't have much problem abouth remembering their ancestors
Imagine being a member of the 600th generation! All you have ever known is the Ship. Same goes to your parents and grandparents. Humanity had forgotten Earth long before you were born. Even if this were the paradise planet..landing there would be the worst possible nightmare that anyone could ever imagine
To be fair, the toilets probably empty out in the open space where they would be frozen and maybe get caught into orbit by a nearby celestial object. And if that was a Meteor on a Collision Course to earth, one could examine the Meteor in the museum with weird brown splotches on it.
Chris Markwardt Space technology is honestly stuck back in the mid 60-70s. Don't confuse Moore's law and the increasing pace of electronic technology with how fast space technology moves. Cars planes and space ships barley get faster, more efficent, year by year. Without new fundemental theory we are stuck here. Reaction mass is a horrible way to move through the stars. Humans haven't been interested in space for decades. We we're supposed to fly out to the outer planets in the late 1980s. But that never happened.
@@WMJCPA And then another generation ship speeds by that one! The chain will forever go on until a MASSIVE ship leaves Earth with only the pilot (probably a descendant, many generations after) on board to pick up everyone else left behind.
I’d be pissed if I was a on stuck on a ship because of my ancestors wanting future gens to go somewhere else. Especially seeing pics and hearing stories of earth. So would a lot of other people. So much so that different factions would arise and fight. Knowing human history...Radicals would eventually blow the ship during its 19,000 year journey.
and if only 100 people are on the ship and only marry each other, in 19,000 genetic changes are very radical and who arrives, it is no longer human. Sorry if the text is not 100% correct. I had to use Google translate
A crash land on Miller's planet would not be a good thing, even if not on the equator where the blackhole makes mega tsunamis due to enormous tidal forces. The aging seven years per hour and increased gravity sound brutal.
Proxima's system is uninhabitable. The colony there would almost have to be a station, not a planetary landing, whose sole purpose would be to become the industrial jumping-off point for further exploration/colonization/refueling of spaceships. CJ Cherryh tackles the Wait Calculation angle (albeit with an FTL drive also in the mix) in her Alliance/Union books. What few "water worlds" have been detected by real modern science are all _much_ further (as in, additional hundreds of generation ship generations) away.
@@xheralt i heard there is a planet like Mercury. Even if it is too hot we can still mine water from the poles and CO2 from rocks and star light for power and make a colony there.
@@fallendown8828 Like Mercury, it's probably tidal locked, so the entire circumference between the hot and cold sides would be habitable with some life support. Not surprisingly, a Star Trek novel 'Twilight's End' by Jerry Oltion, explored this very concept.
I think it's safe to assume that after 600 generations spent in a closed environment subject to radiation and mutations what comes out at destiny location would be an entirely new species.
dzejrid They would actually need extensive shielding from both solar radiation and interstellar radiation (Cosmic rays). Otherwise the exposure wouldn’t cause positive mutations, but major cell disruption, and death by radiation sickness. Don’t forget, we’ve only sent 24 men beyond Earth’s magnetosphere. And that was for a maximum period of about two weeks, not 600 generations.
An operation like this would be so delicate and even human on board born each generation would have to be inhumanely monitored. Imagine someone, just one person a few generations in, deciding they think it’s unfair their ancestors decided their lives for them and stole their lives and went on a murder rampage? Or tried to sabotage the whole mission out of spite or some sort of disease broke out in the tiny space? So much could go ohh sooo wrong and it would all be in vain. The only real solution would be doing it in two generations or less.
"Imagine someone, just one person a few generations in, deciding they think it’s unfair their ancestors decided their lives for them and stole their lives and went on a murder rampage?" That would be a justified rampage, NOT a "murder rampage". First, the ONLY ones who murder/kill people are breeders: anyone who has children. Forcing someone into existence without their prior consent, knowing they will die some day, is murder.
The Helios probe is a terrible measurement for how fast we can make modern spacecraft fly between stars; it only moves that fast because it picked up a lot of kinetic energy falling towards the Sun. But it's an even worse measurement of how fast we could _ever_ make spacecraft go, because there are many known options that work under known science and just require more space infrastructure. The simplest is the so-called "laser highway," which uses a large number of space stations with lasers to push craft up to a significant percentage of the speed of light. Isaac Arthur has a lot of great videos about that and other interstellar colonization tools on his TH-cam channel.
Yes, but in order to get said laser highway to work, you still need to get to that star and set up shop. A fusion drive capable of 0.05 c to 0.1 c would be able to get to Proxima Centauri in 90 to 45 years. And that technology may exist in the next century or even less. However, who knows how long it will take to build a massive ship capable of not only surviving centuries in space without resupplies, but also to sustain a population in the tens of thousands permanently (At least. To preserve genetic diversity). We would also need more research into solar sails to make them as reflective and heat resistant as possible, while also building up the infrastructure to support multi-giga/terawatt laser arrays capable of firing on a minuscule (A few dozen kilometers is pretty tiny in the grand sceme of things) target hundreds to thousands to tens of thousands (and more!) kilometers away. We haven't even set up a Moon base yet, it will be decades until we can viably do that, and probably decades more to develop something that's able to send humans, and their respective payloads to other stars. I think there's still a possibility that we'll send an un-crewed probe to another star in the 21st century. Whether or not it also _arrives_ in this century is probably unlikely, and we may send humans to another star in the next century over, but who knows what roadblocks we'd be up against that we haven't found. I'm more excited to see us colonizing the solar system first. Plenty still left to do here. Isaac Arthur is great btw. I actually have a few of his videos in my recommended feed right now xD
After 600 generations of living in space there would be no way the people on that ship would ever be able to even stand on a planet. Who knows what living in space for your entire life would do to your body, I mean look at what it does to astronauts after just a few months.
The take on this problem that I liked best is that, after so many generations, the crew of the generation ship would know no other life. So what if, after 19,000 years of travel, then they arrived no one wanted to leave the ship?
Good point.... They would be "shit scareless" to step out... And would spend the next 300 years in therapy at the door saying: "Baby steps, Baby steps, good, good, now the other foot..."
@@blizzard1198That could be taught through study and simulations - assuming the whole "society" within the ship doesn't completely collapse and all knowledge isn't forgotten or suppressed at some point during those 19 000 years - which given humanity's history so far, is not exactly far fetched.
Toast4tw . Forget about it. They will travel close to the speed of light... Imagine slowing down, ducking and then another acceleration... To much energy needed...
+Matthew - the generation ship could receive radio transmissions from Earth. Since they're only going up to 4 light years away, their news of Earth would be at most 4 years old. Thus the generation ship crew could learn about new technologies for going faster. Unfortunately for the generation ship crew, they could only receive information via the radio, not hardware upgrades. That would limit what they could build out of the material on the ship that they started with. But of course a faster ship that started later could in theory dock with them, but that would require a vast energy expenditure for the faster ship to decelerate to match speed with the older ship, and then accelerate again after offloading the crew.
Unless you have children you're not really making any contribution to our generational ship. The fact that you're suicidal means that it's probably a good thing if you don't have children. Thank you for keeping out of the gene pool.
The solution to the wait calculation is to keep track of everyone you have launched already, so that a faster ship travelling in the same direction can rendevous with the older, slower ship, transfer everyone aboard, and continue at the faster speed.
Why waste a perfectly good habitable hull? Taking on a whole other crew/passenger manifest vastly increases the size of the overtaking ship, and size creates problems. More mass = bigger engine needed to reach desired acceleration + more propellant + more consumables = still more mass; rinse and repeat until you hit a workable min/max. See my posted solution.
Ah.... Nope! If you had to stop to make the transfer, your speed "momentum" would be screwed up and the fuel or inertia of the faster ship would completely put the faster ship at peril... All for what? With the older tech of the slowest ship, All you would probably find inside would be a ship that would look more like an "Asylum" full with mentally gone folks rather than normal people... I wouldn't even consider stopping for that... Hey... Tough tits...
Faint Wolf What? Your stupid fucking subhuman shit pool of genes self used the wrong form of your. Try to understand my previous comment and take a look at yours.
Most assume that the ship would have some kind of shielding. Remember on the Star Treks like Voyager and TNG and Enterprise you hear them mention "shields".
No this is Patrick Warp drive. That way, we don’t go faster than light, but rather we appear to be traveling faster than we really are due to space being compressed in front of the vehicle and stretched behind the vehicle.
Julia Crawford I feel that the hyperdrive from Star Wars might make sense, you don’t go FTL in the normal realm, but using a hyperdrive, you are dropped into a different dimension where the speed of light is altered. The hyper drive then drops you out of hyperspace when you are at your destination in real space. If we could somehow do that, we could travel ftl (kinda) without actually going ftl.
datboi knows best That's true, but that's not really how dimensions work. You could possibly enter the 7th dimension to find a universe where the laws of physics are different, and thus technically still follow the laws of physics. But you risk erasing yourself in the process, if it's even possible to access it from your space, and of course the energy restraints are so great you might as well use a warp drive. In fact, both hyper drives and warp drives would require exotic matter because hyper drives seem to work like an Einstein-Rosen Bridge (wormhole).
Obviously for a generation ship to have any hope of working, humans would need to have discovered technology for breeding humans with the "right stuff." Currently we select astronauts from an enormous pool of candidates. But on the generation ship, you would have to insure that only astronaut material could be born. There would be no resources to waste on someone who couldn't fulfil their duty. Criminals, drug addicts, people with low IQs, people with mental illnesses - you couldn't afford anyone like that on a generation ship.
longdick69: you do realize that it would take more than twenty people (or so) for an endeavor of these proportions? Mass murdering hundreds of people on a space ship and getting away with it would be very unfortunate for the mission, but not very realistic!
There was a recent sci-fi movie that is about one of these ships where some of the cryogenic pods malfunction and the people inside wake up early as a result. What was the movie called though, I can't remember
Actually this ship is not stuck, because we're moving in space all the time, with our solar system, with our galaxy, with our cluster of galaxies and so on.
I know right? While she has traveled a whole lot, my grandmother is 75 and has lived the entire 75 years in like 3 different houses in the same city. She's been in the house she's in now since like 1968.
The problem lays with humanity, people couldnt live in peace on a planet. This is going to be way worse on a ship... for 20.000 years its just not possible.
As soon as you get to about 1/2 the speed of light relative to the interstellar medium the nose cone of your vehicle will be about the same temperature as your exhaust. The 'bugs on a windscreen' problem is often ignored.
The United States spends enough money on a single modern aircraft carrier to create a functional space battleship or several space frigates with 1962 technology.
If we ever do this, we need a contingency plan for the exact scenario. Maybe make the ship so that it can easily be found, retrofitted, and pushed up to speed while enroute. I think for the foreseeable future, that generation ship would be too valuable of a resource, both human and material, to pass up.
Note that the "Wait Calculation" problem never prevented ancient man from migrating to six of the seven continents on Earth. This is because another continent was never the destination, building a new village over the next hill was. The secret to slower than light migration to nearby stars will be not having those stars as the destinations but of building large space habitats such as O'Neill Cylinders where ever we find the resources to do so. These self sustaining habitats would be the destinations not nearby stars.
+Aditya Narasimhan manthri You've seemed to miss the boat on this one. We're talking about the wait calculation for interstellar travel where one must decide between going forth at the speed available versus waiting for transportation at a faster speed and I mentioned how Stone age man migrated to six of the seven continents on Earth irrespective of the wait equation not by actually intending on going to other continents but by justing building another village over the next hill. This has nothing to do with "European advancement over aborigines", if anything, the Europeans were the least advanced at the time. It's about how the Aborigines got there and became established before the exploitative Europeans came upon them if you wish to consider that as "advanced". However, go placate your self worth by calling Europeans advanced over indigenous people dispite it being irrelevant to the discussion.
O'Neill cylinders are designed to orbit around stars. That's a negligible volume of space. There's almost nothing in the vast distances between stars to support life. If the Sun were the size of a basketball, Earth's orbit would be about 25 meters away. That's about where all the O'Neill cylinders would orbit, to stay in the Solar System's habitable zone. The nearest star would then be about 5500 miles away. You'd have to cross all that distance to reach the next habitable zone for an O'Neill cylinder. If you found some portable source of limitless energy, so the O'Neill cylinder would work in the cold dark void between stars, and you could develop recycling technology to a high enough level so the cylinder would work where there are no material resources to mine, then it would be a generation ship.
+@@danielmocsny5066 The paired O'Neill Cylinders first depicted with the three areas of glass and the reflective mirrors were designed to orbit a star but a completely sealed cylinder using artificial lighting and nuclear power whether fission or fusion could easily be interstellar as depicted by the novel "Rendezvous with Rama". It would also not need the paired cylinder attached to cause it to rotate as it orbited the star. With fusion, deuterium is plentiful throughout the Universe, and with a Thorium breeder fission reactor, Thorium is much more plentiful than uranium and can be detected from orbit by it's unique magnetic signature so it should be harvestable from asteroids, comets and rogue planets. You're rather limited in imagination if you cannot conceive of a variant of the O'Neill cylinder that is independent of proximity with a star.
Nomadic interstellar colonies are O'Neill colonies of some sort which eat comets in between the stars. All you need to live hundreds or thousands of AU out is a comet body to eat and a big mirror. They set out not to go to another star, but to catch a new comet body, and they don't need to try for any top speed. They need whatever speed takes them a few AU to a new comet body, before they run out of the one they're currently eating. They're multi-generation in that they live on artificial colonies, but they're not expecting to get anywhere but a new reservoir. Note that even 1000AU out, they're not completely out of contact. Freeman Dyson looked at how big a ship could be made with what we know. For 1.C it was a pathetic starship, but it covers 100 AU in 17 days at peak speed. 1960s foreseeable technology. If you dispute it, then present your credentials, and let us know what Dr Dyson says of your brilliance, since you must know more than he.
@@brunomarkovic6651 if travel to future where known neural interface and A.I is already advanced enough and very normal quickly boring because too very advanced
We have traveled across continents, sailed around the world, set our foot on the moon, and came across planets in our solar system, interstellar travel will happen.
@@IsraelCountryCube They might not have to die, or at least for a very long time, longer lives can be achieved with methods such as cryo/hyper sleep, nanobots, or genetic engineering, heck if the crew has to procreate and live there entire life on the ship it should be enjoyable but with limits of course.
If you send an expedition to another star using a generation ship, by the time it gets back, the crew will no longer be human. Even with massive shielding, cosmic ray changes to the genome will have created a new species.
I couldn't have said it better myself. Of course it would be even better if we just sent all the bozos into space instead. I can think of several places where I would like to send them, just off the top of my head.
Why not create a constant ping of the ships location? Send out a ship now, but it constantly tells us its location - so when we do develop faster modes of transport we will be able to meet those colonists and use the station as a mobile space station/rest stop of sorts. Just build the entire ship to operate as a giant space station so that when technology does catch up, it can be actually useful and the people living on there can be moved to other places faster. We won't have this problem because you could use each generation of colony ships as just more and more rest stops along the way.
Thats actually a good idea, the generational ship itself can make a slow transition into mobile space station as you ferry colonists out and paid workers in.
Yeah, exactly. You could even slowly decommission them. This entire problem is solely a theoretical problem, it doesn't take any practical solutions into consideration. You could even just upgrade the ship over time as well as tech improves.
Problem is the newer, faster ships in the future would not be travelling in the same trajectory as the earlier, slower ships, hence they might never meet.
This video makes the classic assumptions that science continues to progress in a positive direction, that civilization does not have a backslide of technology, and that humanity gets the chance to exist long enough for science to progress.
Humanity is the only thing worth believing in. Most of us not so great by ourselves and even in large groups, but as a species, as a whole we rock, mate. Fuck nations and religions all hail humanity united. We will conquer the stars!
I would board that first generation ship in a heartbeat, even if the chances of another ship beating my ship to the star was 99% Someone has to be first, waiting around for potentially thousands of years until we have mastered Near-light propulsion is a massive risk for humanity, i would rather board a generation ship knowing that my journey would almost certainly be unnecessary then continue to risk having all of humanities eggs in one basket plus, being on the first manned ship sent into interstellar space would be worth it all
the inherit assumption he makes is wrong. going at 50% light speed is hard but we have concept to achieve5-10% so no reason to think we wont have those as functioning engines in a few hundred years, then at least for our cosmic neighborhood the waiting problem is solved as it becomes 1-2 generations of travel and the chances of anyone beating you to the punch become almost non existant ( i.e it will probably take a few decades to come up with a whole new drive prefect test and send it on its way after you but even if some one does get the a year or 20 before you he will be a very recognizable human from the same civilization you left
The speed that we find safe. The faster we get, the more fatal would a single small particle in front of our space craft be. Unless we develop something for that...
This is my idea: 1. Go to mercury first 2. Get recources 3. Use recources for making dyson swarm 4. Dyson swarm will probably give us almost unlimited energy 5. All of those recources and energy should give us the ability to go speed

The Cancer Of The Internet please allow me: Top speed of a corolla is 190 kmph x fastest rocket 15.73 ms (an hour has 3600 sec x 15.73 = 56,628 metres per hour) 190 x 56,628 =10,759,320 kmph So a rocketed powered Corolla would take a fucking long time to reach the 4.37 light year distance of Alpha centuri. Remember a light year is measurement of distance not time, it's the distance light travelled in a year.
I had to come back to this video to describe a situation that happened to me. Due to COVID, Amazon shipping times were around 10-14 days. I ordered something back in May 26 and the delivery date is June 7. Today (June 1), I ordered something else and it was back to two day shipping and the expected delivery date is June 3. The Wait/Walk Dilemma is real!!!!!!!!!!!!!!! Also another real-life situation is waiting for a bus or walking to your destination. Very interesting concept...especially if you've been a victim of it.
One thing I find really interesting is that once we do figure out how to go an appreciable percent of light speed, we can travel almost anywhere in a human lifetime. Even though the could take millions of years to reach its destination, from the perspective of Earth, the people on the ship will age so slowly due to time dilation that you can cross the universe in what feels like a single century, even with acceleration less than 1g. For example, a ship that accelerates at 1g constantly to provide gravity could reach the Andromeda galaxy in what feels like less than 29 years.
Is that really true?? Say we could travel at 50% the speed of light, how many years would it feel like to the people on board the craft to travel 100 light years? 50 years?
It is true, at 0.5c, 100 years on the Earth would pass in ~86.6 years for the ship passenger. Also, to travel 100 ly at 0.5c would take 200 years from Earth point of view, while on ship they would experience 173.2 years, but perceive that as a shorter travel distance. You'd need to travel at ~0.866c for ship passenger to experience 50 years during 100 years on Earth. This is a little simplified approximation, as main difference comes during acceleration and deceleration from that speed.
To go from one end of the milky way galaxy to the opposite end will take 100,000 light years. Even if we could save our body as light data and travel at the speed of light, it would take 100,000 years to travel the galaxy. And the next closest galaxy is 2.5 million light years. "almost anywhere" is not true, our galaxy is one of billions of billions of galaxies, we haven't even touched the surface of this universe, not to mention any other possible universes. For all we know there could be a planet made of only water with mermaids, a planet where cockroaches are just as smart or smarter than humans and human size, a donut shaped planet, 3 stars in a solar system, a planet where it rains soda. So many possibilities, and we won't be able to get to the unless we have a teleporter or something.
JUanHernandezism only from the observers perspective. On the ship, if you accelerate at 1g, earths gravity, then you can reach 99% the speed of light in only a few years. When you are moving that fast something happens called length contraction, where distances in front of you appear shorter, and in fact are shorter in every meaningful way. So if you were on this ship, you could travel to the other side of the galaxy in your own lifetime.
"3 stars in a solar system" dude ...you know why it's called alpha centauris? because it's the first star of the multi star system centauris. how many in the system? 3 :) " a donut shaped planet" physically possible if the planet spin very fast , the only problem is how it would form in the first place.
If humanity could travel near the speed of light, due to the properties of time dilation, the passengers should not feel that the journey took a long time, although in reality a lot of time has passed on earth
Donald J. Trump If that is your real name, then yes, you are stupid no matter what. However, if that is not the case, you are not stupid because many people do not get it too. It took Einstein many years to study, and it is so weird that it does not even make sense when speeds are far lower than the speed of light. So, to answer your question, yes, the ship will go at the same speed, but to the passenger's perspective, they will not feel that they are fast at all, they just see the outside view get compressed expand again when they arrive.
A Lonely Person I have never heard of hyperspace, but some googling has shown that it is faster-than-light travel. Under the laws of physics it is impossible. They key here is to reach close to the speed of light, which is still possible, so it is nothing like hyperspace.
A Lonely Person As I said, hyperspace is impossible, and that reality can never be similar to something completely made up. By nature they are different things, so a valid comparison cannot be made. Furthermore, I do not know what you your interpretation of hyperspace is (because it is fictional), which adds to the difficulty of comparing. Go look up special relativity if you want more accurate information
Yoh. A well actually it is, star systems are bound so far from each other that light speed even falls short in front of it! Light is actually tremendously fast, and space is tremendously squared squared squared huge!
INVIAM PSBOXTENDO Well, no. Space, could always get bigger. No problem with that, but speed has a limit? Not legit, not at all, unless if course ityfast enouto travel through the univers in no time. But a ray of light can never travel the whole universe. Thats a problem, a riddle, אומר דרשני. Space? Space is no problem, but why limit on speed?!?!?!
How about we build a generation ship that is modular? If we could somehow reach the generation ship and upgrade their propulsion and living conditions while on the way, then they could arrive earlier than expected. Simultaneously arriving at the same time on the planet.
Good video as usual, although it’s worth mentioning that the 240,000 km/h that Helios 2 reached was only possible because it was basically falling into the sun. It’s periapsis (or perihelion I guess) was quite close to the sun.
I was thinking the same thing. Perhaps the Generational ship crew improved upon its own technology along the way? Plus, what kind of mutations might happen over 600 generations? Eventually, the Humans turn into ‘Grays’, they create their own FTL propulsion, and arrive on Earth. In the meantime the earlier human arrivals have regressed to our current level of technology? Hmmm 🤔
Not necessary. Send spaceship with AI and other technology that can create human life and when the spaceship gets close to the destination it will create the human life and raise and take care of the human life. Would send huge amount of supplies and tech to ensure success of colony.
To all of you thinking you'll give the previous ship a tow,That's not how these things work,you'll have to slow down, attach both ships then find a way to accelerate to your initial speed in interstellar space without any gravity assists so not an option,also it's not a tared road where you're likely to overtake them at some point,Space is massive and everything is relatively in motion,so the position of the earth,our sun,our solar system,other stars,our galaxy,etc will be thousands of light-years from where they where thousands of years ago thus the path taken by both space crafts although both originating from earth and having the same destination will most likely be light-years apart.
So when an Alien spaceship arrives at Earth and the inhabitants look just like us, should we assume that we are the descendants of the fast ship, and they are our slower great-great-great...grandparents?
@@danshakuimo I don't know, anything could happen. Maybe the ship crashed and nearly everyone died, but the few survivors lost all records and technology.
A Generation ship is the silliest interstellar travel idea. That long in space would destroy the human body and make colonizing the planet almost impossible, living in a tiny ship would drive everyone crazy, etc. Why don’t people talk about suspended animation, or freezing embryos, more? Until we figure out warp drives of course 🙂
There has been wild speculation that Earth could be a generation ship. Unfortunately, we've forgotten our original purpose and don't even know we're traveling to somewhere in the Milky Way, hitched to the sun.
People who have spent their entire lives in a space ship would be horrified the first time they left the ship on the surface of a planet. They have been evolving for 19 thousand years, to live in an aluminum box. That is, of course, leaving aside the the many, many problems that would make such long trips very, very difficult, if not impossible. The cosmic ray problem will have to be solved before such a thing could happen. Human nature is such that I suspect future colonialists will set out as soon as it is at all possible, not counting on future development. By they time they got there, the human species on earth might be extinct.
I remember as a kid, I used to think stars were just little specs of light that you could touch in outer-space lol I remember the day in school that I found out that those specs were actually distant sun’s just like our sun but super far away & you could never touch them! I was mind blown 🤯 Even today when I explain to other people that don’t know about space that those specs of light you see in the sky are actually distant sun’s just like our sun! it’s always fun to see them be mind blown just as I was all those years ago ☀️💫🚀🌎
If the speeds at which humans of the future can travel are that fast, then wouldn't any previous space voyages be looked at like they were basically sitting still and almost immobile. They would be stranded in a sense, in need of rescue. And why wouldn't our posterity "rescue" or assist them? Just saying, we don't have to leave them there to travel at their original speed. Future tech could be piloted to older ships and retrofitted to shorten the total duration.
I mean, given all of the people that agreed to go on a one way trip to mars, I assume that there would be people willing to sign up on a generation ship.
Surprised no one has thought about constructing a solar sail out of a material consisting of billions of single-atom-thick sheets of e.g. silicon all positioned a nanometer or two away from each other in such a way as to create a Casimir effect when stellar radiation pressure is applied. Solar sails themselves are capable of achieving incredible speeds even without the Casimir effect; now take into account the extreme mass-energy differential that integrating the Casimir effect directly into a solar sails would have, with positive radiation pressure behind the solar sails and negative radiation pressure inside them. Then there’s the positive feedback loop that sweeping up high energy particles into the resulting warp bubble would have - the solar sail would catch them and accelerate even further as a result.
What if we could figure out a way to cryogenically freeze people in a way that it would be totally possible to revive them once they reached the planet? It might nullify the wait calculation, because then rather than having a ship full of people who would constantly regenerate, it would be like the equivalent of a kid falling asleep during a long car ride and suddenly waking up to realize they're home?
I mean, why can't they just have docking ports? Faster ship rendezvous with slower ship, picks the people up and gets them there faster. Hell we could get technology going so fast that we'll be there yesterday!
we will invent Warp drives by then. Im sure 200 years ago its impossible to conceptualize what a spacecraft would be like. Thats us now with interstellar travel.

My thought exactly.
It would be messed up if they didnt.
Yeah I’m sure they would show up, thank them for their efforts, and take them to the new planet. Surely they could find their location- all very predictable math. They would be incredibly curious what happened to those first travelers too.
The speed might rip the old ship apart now that it’s 1000 years old.

When I was a kid, the fastest spacecraft would take 42000 years to reach Proxima. Now it only takes 19000 years. We've already cut it more than in half.
@Sahil Ali
Of course it is, but that's not the point.
Each time a scientific advancement is made, it makes the time necessary for travel that much more shorter.
Which in turn makes everything that much "closer" to us.
150 years ago, it used to take an entire summer, risking your life, just to make it to the west coast.
Now it's a 5 hr flight.
We used science to figure out ever faster methods of travel on our planet and we will do the same in space.
It all depends on how badly we want to get there.
u still a kind tho
@Hdye Hdhde I see your point, but like I said it all depends on how badly we want to get there.
When the United States wanted to build a nuclear device, they gathered up the best and the brightest scientists, put them all in a secret location and had one operational in 3 years.
Money is probably the biggest barrier. R&D is a notoriously expensive operation. On top of that you need the right people. And just to make it a little bit more of a pain in the ass, they also have to obey certain legal restrictions, as well as International treaties that ban certain materials or activities in space.
Now, if there was a rich philanthropist that wanted to undertake it as a pet project along with other entities, kind of what like Elon Musk is doing with Mars missions, then maybe public interest would peak enough, to have something come together.

"When is the optimal time for humanity to send colonists out to another star?" Definitely not when it takes 19'000 years and 600 generations!!!
Etienne Aubert well what if it always stays like that? What if in 10000 years we still would need 19‘000 years should humanity never leave the solar system?
Then there is the counter problem... waiting too long. We're assuming that the modern advanced civilization we enjoy today will at least last forever and probably get even better. There is nothing preventing humanity's extinction or slipping into a more primitive state. Maybe anti-vaxxers and flat-Earthers become the rulers and throw out modern technology. Or climate change breaks civilization. Or fossil fuels run out before we have decent alternatives. Something happens and humanity loses the ability or interest to go to space.
@@CarFreeSegnitz Humanity will continue to advance no matter what. I am sure in times of great crises people would always thought that it was trully the end of the world. But guess what. All of these passed and we still go on.

I'd say if it can take at least within a human life span or 2 would be probably feasible, but I do believe that we could do it within the human lifespan.
And when we arrive there, we find no suitable planets...
So then we turn around and come back to find humanity no longer exists on Earth.

Similar situation with that garbage barge that sailed around the world looking for a home a few years ago.
I mean.. wouldn’t the newer, faster ships just give the original colonists a courtesy tow or something?
Exactly my thoughts. Or at least they could you know.. TEXT them.. ^Hey guys.. we got a better new & improved ship..^
I mean.. unless the new technology involves wormholes or some esoteric things which would make them get there instantly... But still, I see now reason why the original ship would be incommunicable...
Exactly. This whole idea seems so dumb. Why can't they pick them up on the way? There would be outrage if we just left them out there to die. Scientists would work hard to create a rescue mission.
The original ship might just be to huge and heavy for the new and improved ship
Yeah, it's just a thought experiment though.
But the problem would really be apparent at higher speeds. Let's say we could instead travel a bit under 1% of the speed of light. Sure, you could slow down to catch up, it would take the ship over ~1300-1500 years to get to Proxima Centuari if you let it coast there otherwise. But the fuel requirements needed to slow down your ship to match the velocity, and then speed back up again would be brutal on your fuel reserves. And you still need to slow down at Proxima Centuari!
Which is why it's still better to wait. If we got a drive capable of travelling at 5% of the speed of light in 200 years, and then it takes us 100 years to build a ship, and then it takes 90 years to get there with that drive, that's still (at least) almost a thousand years faster than if you went early.
A really big problem is that thousands of years means you're quite apt to forget what you were doing entirely.
yes but you still have all the knowlage we have in Earth because we will send them with the guide that tells them the phisic laws and how to colonize a planet and it will also say your ship has limited resources so you HAVE TO colonize a planet over there. And say it would be cool to send a letter after you arived there because we are courious what you have done

Imagine the ship's toilets after 600 generations.
By my calculations there will be approximately 155,685kg of shit and piss by that time.
They can throw out ?
imagine the shower drains, stringers!
food?
To be fair, the toilets probably empty out in the open space where they would be frozen and maybe get caught into orbit by a nearby celestial object. And if that was a Meteor on a Collision Course to earth, one could examine the Meteor in the museum with weird brown splotches on it.
We haven't even stepped into our backyard, kinda hard to expect us to go cross-country.

Yes, though science and technology is growing exponentially, which is known to grow much faster than humans intuitively expect.
I agree
Chris Markwardt Space technology is honestly stuck back in the mid 60-70s. Don't confuse Moore's law and the increasing pace of electronic technology with how fast space technology moves. Cars planes and space ships barley get faster, more efficent, year by year. Without new fundemental theory we are stuck here. Reaction mass is a horrible way to move through the stars. Humans haven't been interested in space for decades. We we're supposed to fly out to the outer planets in the late 1980s. But that never happened.

@@WMJCPA And then another generation ship speeds by that one! The chain will forever go on until a MASSIVE ship leaves Earth with only the pilot (probably a descendant, many generations after) on board to pick up everyone else left behind.
I’d be pissed if I was a on stuck on a ship because of my ancestors wanting future gens to go somewhere else. Especially seeing pics and hearing stories of earth. So would a lot of other people. So much so that different factions would arise and fight. Knowing human history...Radicals would eventually blow the ship during its 19,000 year journey.
but how could you know the concept of not stucking somewhere since you are born on a ship.
One could certainly make the argument that a generational ship is straight-up unethical to those who would be born there.
Honestly this scenario sounds something straight out of a Rick and Morty episode 😂
and if only 100 people are on the ship and only marry each other, in 19,000 genetic changes are very radical and who arrives, it is no longer human.

Imagine traveling for 19000 years only to discover ProximaB is uninhabitable 😀
Proxima's system is uninhabitable. The colony there would almost have to be a station, not a planetary landing, whose sole purpose would be to become the industrial jumping-off point for further exploration/colonization/refueling of spaceships. CJ Cherryh tackles the Wait Calculation angle (albeit with an FTL drive also in the mix) in her Alliance/Union books. What few "water worlds" have been detected by real modern science are all _much_ further (as in, additional hundreds of generation ship generations) away.

I think it's safe to assume that after 600 generations spent in a closed environment subject to radiation and mutations what comes out at destiny location would be an entirely new species.
Brooooo ur right
mars ? mars is not another star , its in our solar system.
william dohn bruh, Star Trek is a tv show, not real life
No it doesn't. It's a constant process in response to changing conditions that never stops.
dzejrid They would actually need extensive shielding from both solar radiation and interstellar radiation (Cosmic rays). Otherwise the exposure wouldn’t cause positive mutations, but major cell disruption, and death by radiation sickness. Don’t forget, we’ve only sent 24 men beyond Earth’s magnetosphere. And that was for a maximum period of about two weeks, not 600 generations.
Sounds like a good movie plot
David Ernst I was thinking the same thing
would be sweet maybe having different interlinking timelines from different generations on the same ship
David Ernst Exactly😂
But then since it's a movie you know something terrible will happen

An operation like this would be so delicate and even human on board born each generation would have to be inhumanely monitored. Imagine someone, just one person a few generations in, deciding they think it’s unfair their ancestors decided their lives for them and stole their lives and went on a murder rampage? Or tried to sabotage the whole mission out of spite or some sort of disease broke out in the tiny space? So much could go ohh sooo wrong and it would all be in vain. The only real solution would be doing it in two generations or less.
"Imagine someone, just one person a few generations in, deciding they think it’s unfair their ancestors decided their lives for them and stole their lives and went on a murder rampage?"

The Helios probe is a terrible measurement for how fast we can make modern spacecraft fly between stars; it only moves that fast because it picked up a lot of kinetic energy falling towards the Sun. But it's an even worse measurement of how fast we could _ever_ make spacecraft go, because there are many known options that work under known science and just require more space infrastructure. The simplest is the so-called "laser highway," which uses a large number of space stations with lasers to push craft up to a significant percentage of the speed of light. Isaac Arthur has a lot of great videos about that and other interstellar colonization tools on his TH-cam channel.
Yes, but in order to get said laser highway to work, you still need to get to that star and set up shop. A fusion drive capable of 0.05 c to 0.1 c would be able to get to Proxima Centauri in 90 to 45 years. And that technology may exist in the next century or even less. However, who knows how long it will take to build a massive ship capable of not only surviving centuries in space without resupplies, but also to sustain a population in the tens of thousands permanently (At least. To preserve genetic diversity).
We would also need more research into solar sails to make them as reflective and heat resistant as possible, while also building up the infrastructure to support multi-giga/terawatt laser arrays capable of firing on a minuscule (A few dozen kilometers is pretty tiny in the grand sceme of things) target hundreds to thousands to tens of thousands (and more!) kilometers away. We haven't even set up a Moon base yet, it will be decades until we can viably do that, and probably decades more to develop something that's able to send humans, and their respective payloads to other stars.
I think there's still a possibility that we'll send an un-crewed probe to another star in the 21st century. Whether or not it also _arrives_ in this century is probably unlikely, and we may send humans to another star in the next century over, but who knows what roadblocks we'd be up against that we haven't found. I'm more excited to see us colonizing the solar system first. Plenty still left to do here.
Isaac Arthur is great btw. I actually have a few of his videos in my recommended feed right now xD
My concern is, if you manage to build up so much speed... how do you stop after you get there?
It was used as an example man, c'mon. It doesn't change what he was demonstrating.
neuron1618 There are plenty of options, ranging from "the same way you sped up" to "drag against the interstellar medium".
I was about to say exactly that. what you accelerate, you need to decelerate at the other end.
After 600 generations of living in space there would be no way the people on that ship would ever be able to even stand on a planet. Who knows what living in space for your entire life would do to your body, I mean look at what it does to astronauts after just a few months.
The ship could implement some kind of artificial gravity using centrifugal force.
David Vatnedal Nordtveit but what about radiation? It’s not only about gravity - studies show extended time in space changes our DNA
maybe they could adopt to thoose conditions who knows
They would become tall and skinny then their skin Will turn green and eye become oval and develop oversized brains
They'd end up killing each other from pure boredom after the first few generations; if that long.
The take on this problem that I liked best is that, after so many generations, the crew of the generation ship would know no other life. So what if, after 19,000 years of travel, then they arrived no one wanted to leave the ship?
Good point.... They would be "shit scareless" to step out... And would spend the next 300 years in therapy at the door saying: "Baby steps, Baby steps, good, good, now the other foot..."
The other problem now how to colonize the planet once arriving
@@blizzard1198That could be taught through study and simulations - assuming the whole "society" within the ship doesn't completely collapse and all knowledge isn't forgotten or suppressed at some point during those 19 000 years - which given humanity's history so far, is not exactly far fetched.

So why are we completely ignoring the possibility that a faster ship could just dock onto the slow one and the passengers could move over?
Toast4tw . Forget about it. They will travel close to the speed of light... Imagine slowing down, ducking and then another acceleration... To much energy needed...
Toast4tw. We are ignoring it so that we can pompously explain the wait calculation.
Same thinking
The premise also ignores the possibility that people on the ship may find a way to make the ship go faster, science will not only advance on Earth.
+Matthew - the generation ship could receive radio transmissions from Earth. Since they're only going up to 4 light years away, their news of Earth would be at most 4 years old. Thus the generation ship crew could learn about new technologies for going faster. Unfortunately for the generation ship crew, they could only receive information via the radio, not hardware upgrades. That would limit what they could build out of the material on the ship that they started with. But of course a faster ship that started later could in theory dock with them, but that would require a vast energy expenditure for the faster ship to decelerate to match speed with the older ship, and then accelerate again after offloading the crew.
Earth is a giant generation ship. I'm not on Earth by choice, but I choose to make this sacrifice every day by not committing suicide.
😂why?
Unless you have children you're not really making any contribution to our generational ship. The fact that you're suicidal means that it's probably a good thing if you don't have children. Thank you for keeping out of the gene pool.
Benedikt Decker If he/she was born in another planet, his/her species would’ve already adapted.
John Smith What sacrifice? Jesus don’t flatter yourself too much
@Point Vlog Earth is fine, it's the people on earth that makes it so bad
The solution to the wait calculation is to keep track of everyone you have launched already, so that a faster ship travelling in the same direction can rendevous with the older, slower ship, transfer everyone aboard, and continue at the faster speed.
@bobwatters no one needs to stop though.
In space you can dock and transfer things at what ever speed you need to.
@bobwatters instruction unclear:never drained energy quickly to 0% in one second
@bobwatters but it could go way faster without humans, slow down a lot, speed up to regular speed and zoom
Why waste a perfectly good habitable hull? Taking on a whole other crew/passenger manifest vastly increases the size of the overtaking ship, and size creates problems. More mass = bigger engine needed to reach desired acceleration + more propellant + more consumables = still more mass; rinse and repeat until you hit a workable min/max. See my posted solution.
Ah.... Nope! If you had to stop to make the transfer, your speed "momentum" would be screwed up and the fuel or inertia of the faster ship would completely put the faster ship at peril... All for what? With the older tech of the slowest ship, All you would probably find inside would be a ship that would look more like an "Asylum" full with mentally gone folks rather than normal people... I wouldn't even consider stopping for that... Hey... Tough tits...

You can always explore the ocean
No one ever mentions the interstellar medium collisions that may happen at relativistic speeds that would destroy the ship.
after you left the oort cloud you will be fine but it can happen in ootr cloud which is relatively close to Sun
Most assume that the ship would have some kind of shielding. Remember on the Star Treks like Voyager and TNG and Enterprise you hear them mention "shields".
But hyper space.....
No this is Patrick Warp drive. That way, we don’t go faster than light, but rather we appear to be traveling faster than we really are due to space being compressed in front of the vehicle and stretched behind the vehicle.
Julia Crawford I feel that the hyperdrive from Star Wars might make sense, you don’t go FTL in the normal realm, but using a hyperdrive, you are dropped into a different dimension where the speed of light is altered. The hyper drive then drops you out of hyperspace when you are at your destination in real space. If we could somehow do that, we could travel ftl (kinda) without actually going ftl.
Futurama did it better, just move the universe around your ship.
Magic
datboi knows best That's true, but that's not really how dimensions work. You could possibly enter the 7th dimension to find a universe where the laws of physics are different, and thus technically still follow the laws of physics. But you risk erasing yourself in the process, if it's even possible to access it from your space, and of course the energy restraints are so great you might as well use a warp drive. In fact, both hyper drives and warp drives would require exotic matter because hyper drives seem to work like an Einstein-Rosen Bridge (wormhole).
What if in midst of the 19,000 year journey, someone decides to go insane on the ship and mass murder the group?
Obviously for a generation ship to have any hope of working, humans would need to have discovered technology for breeding humans with the "right stuff." Currently we select astronauts from an enormous pool of candidates. But on the generation ship, you would have to insure that only astronaut material could be born. There would be no resources to waste on someone who couldn't fulfil their duty. Criminals, drug addicts, people with low IQs, people with mental illnesses - you couldn't afford anyone like that on a generation ship.
Probably something similar to what happens to insane mass murderers today...
longdick69: you do realize that it would take more than twenty people (or so) for an endeavor of these proportions? Mass murdering hundreds of people on a space ship and getting away with it would be very unfortunate for the mission, but not very realistic!
Not if they used CBW (e.g. a lethal virus)

If we ever do this, we need a contingency plan for the exact scenario. Maybe make the ship so that it can easily be found, retrofitted, and pushed up to speed while enroute. I think for the foreseeable future, that generation ship would be too valuable of a resource, both human and material, to pass up.
Note that the "Wait Calculation" problem never prevented ancient man from migrating to six of the seven continents on Earth. This is because another continent was never the destination, building a new village over the next hill was. The secret to slower than light migration to nearby stars will be not having those stars as the destinations but of building large space habitats such as O'Neill Cylinders where ever we find the resources to do so. These self sustaining habitats would be the destinations not nearby stars.
+Aditya Narasimhan manthri You've seemed to miss the boat on this one. We're talking about the wait calculation for interstellar travel where one must decide between going forth at the speed available versus waiting for transportation at a faster speed and I mentioned how Stone age man migrated to six of the seven continents on Earth irrespective of the wait equation not by actually intending on going to other continents but by justing building another village over the next hill. This has nothing to do with "European advancement over aborigines", if anything, the Europeans were the least advanced at the time. It's about how the Aborigines got there and became established before the exploitative Europeans came upon them if you wish to consider that as "advanced". However, go placate your self worth by calling Europeans advanced over indigenous people dispite it being irrelevant to the discussion.
O'Neill cylinders are designed to orbit around stars. That's a negligible volume of space. There's almost nothing in the vast distances between stars to support life. If the Sun were the size of a basketball, Earth's orbit would be about 25 meters away. That's about where all the O'Neill cylinders would orbit, to stay in the Solar System's habitable zone. The nearest star would then be about 5500 miles away. You'd have to cross all that distance to reach the next habitable zone for an O'Neill cylinder. If you found some portable source of limitless energy, so the O'Neill cylinder would work in the cold dark void between stars, and you could develop recycling technology to a high enough level so the cylinder would work where there are no material resources to mine, then it would be a generation ship.
+@@danielmocsny5066 The paired O'Neill Cylinders first depicted with the three areas of glass and the reflective mirrors were designed to orbit a star but a completely sealed cylinder using artificial lighting and nuclear power whether fission or fusion could easily be interstellar as depicted by the novel "Rendezvous with Rama". It would also not need the paired cylinder attached to cause it to rotate as it orbited the star. With fusion, deuterium is plentiful throughout the Universe, and with a Thorium breeder fission reactor, Thorium is much more plentiful than uranium and can be detected from orbit by it's unique magnetic signature so it should be harvestable from asteroids, comets and rogue planets. You're rather limited in imagination if you cannot conceive of a variant of the O'Neill cylinder that is independent of proximity with a star.
My thoughts exactly. Very well said, Mr. Wang.
Nomadic interstellar colonies are O'Neill colonies of some sort which eat comets in between the stars. All you need to live hundreds or thousands of AU out is a comet body to eat and a big mirror.
They set out not to go to another star, but to catch a new comet body, and they don't need to try for any top speed. They need whatever speed takes them a few AU to a new comet body, before they run out of the one they're currently eating.
They're multi-generation in that they live on artificial colonies, but they're not expecting to get anywhere but a new reservoir.
Note that even 1000AU out, they're not completely out of contact. Freeman Dyson looked at how big a ship could be made with what we know. For 1.C it was a pathetic starship, but it covers 100 AU in 17 days at peak speed. 1960s foreseeable technology.
If you dispute it, then present your credentials, and let us know what Dr Dyson says of your brilliance, since you must know more than he.
The speed of light is the universes refresh rate

I'd get on board the ship no matter how slow it is, if for nothing else just to get away from the bozos in charge on this rock today.
shutcho clown ass up
Imagine how much sleep you'd get
I couldn't have said it better myself. Of course it would be even better if we just sent all the bozos into space instead. I can think of several places where I would like to send them, just off the top of my head.
Just to find out you are now trapped on a ship with a bozo in charge for the next 18000 years.
The bozos in charge on your ship will probably be worse.
Why not create a constant ping of the ships location? Send out a ship now, but it constantly tells us its location - so when we do develop faster modes of transport we will be able to meet those colonists and use the station as a mobile space station/rest stop of sorts.
Just build the entire ship to operate as a giant space station so that when technology does catch up, it can be actually useful and the people living on there can be moved to other places faster. We won't have this problem because you could use each generation of colony ships as just more and more rest stops along the way.
Thats actually a good idea, the generational ship itself can make a slow transition into mobile space station as you ferry colonists out and paid workers in.
Yeah, exactly. You could even slowly decommission them.
This entire problem is solely a theoretical problem, it doesn't take any practical solutions into consideration.
You could even just upgrade the ship over time as well as tech improves.
How are you gonna slow down the ships for a meeting to even be possible?
Zeruss01 presumably the same way they would slow the ship once they reached the planet
Problem is the newer, faster ships in the future would not be travelling in the same trajectory as the earlier, slower ships, hence they might never meet.

It's nice to see someone in the comments focusing on solutions.
I would board that first generation ship in a heartbeat, even if the chances of another ship beating my ship to the star was 99%
Someone has to be first, waiting around for potentially thousands of years until we have mastered Near-light propulsion is a massive risk for humanity, i would rather board a generation ship knowing that my journey would almost certainly be unnecessary then continue to risk having all of humanities eggs in one basket
plus, being on the first manned ship sent into interstellar space would be worth it all
the inherit assumption he makes is wrong. going at 50% light speed is hard but we have concept to achieve5-10% so no reason to think we wont have those as functioning engines in a few hundred years, then at least for our cosmic neighborhood the waiting problem is solved as it becomes 1-2 generations of travel and the chances of anyone beating you to the punch become almost non existant ( i.e it will probably take a few decades to come up with a whole new drive prefect test and send it on its way after you but even if some one does get the a year or 20 before you he will be a very recognizable human from the same civilization you left

What if Earth is our ship and we just forgot after all this time 🤯
@@ramones53rd3rd so we are struck in a random star's gravity, but where are we going
I had to come back to this video to describe a situation that happened to me. Due to COVID, Amazon shipping times were around 10-14 days. I ordered something back in May 26 and the delivery date is June 7. Today (June 1), I ordered something else and it was back to two day shipping and the expected delivery date is June 3. The Wait/Walk Dilemma is real!!!!!!!!!!!!!!!
Also another real-life situation is waiting for a bus or walking to your destination. Very interesting concept...especially if you've been a victim of it.
One thing I find really interesting is that once we do figure out how to go an appreciable percent of light speed, we can travel almost anywhere in a human lifetime. Even though the could take millions of years to reach its destination, from the perspective of Earth, the people on the ship will age so slowly due to time dilation that you can cross the universe in what feels like a single century, even with acceleration less than 1g. For example, a ship that accelerates at 1g constantly to provide gravity could reach the Andromeda galaxy in what feels like less than 29 years.
Is that really true?? Say we could travel at 50% the speed of light, how many years would it feel like to the people on board the craft to travel 100 light years? 50 years?
It is true, at 0.5c, 100 years on the Earth would pass in ~86.6 years for the ship passenger. Also, to travel 100 ly at 0.5c would take 200 years from Earth point of view, while on ship they would experience 173.2 years, but perceive that as a shorter travel distance. You'd need to travel at ~0.866c for ship passenger to experience 50 years during 100 years on Earth. This is a little simplified approximation, as main difference comes during acceleration and deceleration from that speed.
To go from one end of the milky way galaxy to the opposite end will take 100,000 light years. Even if we could save our body as light data and travel at the speed of light, it would take 100,000 years to travel the galaxy. And the next closest galaxy is 2.5 million light years. "almost anywhere" is not true, our galaxy is one of billions of billions of galaxies, we haven't even touched the surface of this universe, not to mention any other possible universes. For all we know there could be a planet made of only water with mermaids, a planet where cockroaches are just as smart or smarter than humans and human size, a donut shaped planet, 3 stars in a solar system, a planet where it rains soda. So many possibilities, and we won't be able to get to the unless we have a teleporter or something.
JUanHernandezism only from the observers perspective. On the ship, if you accelerate at 1g, earths gravity, then you can reach 99% the speed of light in only a few years. When you are moving that fast something happens called length contraction, where distances in front of you appear shorter, and in fact are shorter in every meaningful way. So if you were on this ship, you could travel to the other side of the galaxy in your own lifetime.
"3 stars in a solar system"
dude ...you know why it's called alpha centauris? because it's the first star of the multi star system centauris.
how many in the system? 3 :)
" a donut shaped planet"
physically possible if the planet spin very fast , the only problem is how it would form in the first place.
If humanity could travel near the speed of light, due to the properties of time dilation, the passengers should not feel that the journey took a long time, although in reality a lot of time has passed on earth
Donald J. Trump If that is your real name, then yes, you are stupid no matter what. However, if that is not the case, you are not stupid because many people do not get it too. It took Einstein many years to study, and it is so weird that it does not even make sense when speeds are far lower than the speed of light. So, to answer your question, yes, the ship will go at the same speed, but to the passenger's perspective, they will not feel that they are fast at all, they just see the outside view get compressed expand again when they arrive.
Nicholas Lau
So basically it's kinda like hyperspace but a little longer than you think ?
A Lonely Person I have never heard of hyperspace, but some googling has shown that it is faster-than-light travel. Under the laws of physics it is impossible. They key here is to reach close to the speed of light, which is still possible, so it is nothing like hyperspace.
No no no, What I mean is that. It's like Hyperspave from the view of the people inside the ship, but in reality it's taking a lot longer.
A Lonely Person As I said, hyperspace is impossible, and that reality can never be similar to something completely made up. By nature they are different things, so a valid comparison cannot be made. Furthermore, I do not know what you your interpretation of hyperspace is (because it is fictional), which adds to the difficulty of comparing. Go look up special relativity if you want more accurate information

Not necessary. Send spaceship with AI and other technology that can create human life and when the spaceship gets close to the destination it will create the human life and raise and take care of the human life. Would send huge amount of supplies and tech to ensure success of colony.
How would the ship even have the resources to support that many humans without the sun's energy input
IKR! It might be able to survive for 100, maybe 200 years, you know what maybe even 1000, due to recycling. But
To all of you thinking you'll give the previous ship a tow,That's not how these things work,you'll have to slow down, attach both ships then find a way to accelerate to your initial speed in interstellar space without any gravity assists so not an option,also it's not a tared road where you're likely to overtake them at some point,Space is massive and everything is relatively in motion,so the position of the earth,our sun,our solar system,other stars,our galaxy,etc will be thousands of light-years from where they where thousands of years ago thus the path taken by both space crafts although both originating from earth and having the same destination will most likely be light-years apart.

If the speeds at which humans of the future can travel are that fast, then wouldn't any previous space voyages be looked at like they were basically sitting still and almost immobile. They would be stranded in a sense, in need of rescue. And why wouldn't our posterity "rescue" or assist them?
Just saying, we don't have to leave them there to travel at their original speed. Future tech could be piloted to older ships and retrofitted to shorten the total duration.

I mean, given all of the people that agreed to go on a one way trip to mars, I assume that there would be people willing to sign up on a generation ship.
"Since you're watching this on a computer - Computer Science". LOL
Surprised no one has thought about constructing a solar sail out of a material consisting of billions of single-atom-thick sheets of e.g. silicon all positioned a nanometer or two away from each other in such a way as to create a Casimir effect when stellar radiation pressure is applied.
Solar sails themselves are capable of achieving incredible speeds even without the Casimir effect; now take into account the extreme mass-energy differential that integrating the Casimir effect directly into a solar sails would have, with positive radiation pressure behind the solar sails and negative radiation pressure inside them. Then there’s the positive feedback loop that sweeping up high energy particles into the resulting warp bubble would have - the solar sail would catch them and accelerate even further as a result.
What if we could figure out a way to cryogenically freeze people in a way that it would be totally possible to revive them once they reached the planet? It might nullify the wait calculation, because then rather than having a ship full of people who would constantly regenerate, it would be like the equivalent of a kid falling asleep during a long car ride and suddenly waking up to realize they're home?
