There is another option. Take the space station concept, turn it into a sealed habitat on a planet or moon with decent enough gravity. It would still suck, but at least we'd have gravity.
No, you would not want to live there, wherever it is. The only option is to protect the planet we are on and clean up the mess we've made. We are stuck here. That likely means large sums of money spent on environmental protection and high taxes on the rich. Sorry you couldn't be rich forever.
Sealed habitat on uninhabitable planet has its own issues. But we don't need any new materials or any new science (although it would help) to start building O'Neill cylinders of 800 km2 Island Three can have earth-like gravity and atmospheric pressure (although O'Neill had half) is so massive, that its hull and atmosphere can protect completely from cosmic rays. We need just some engineering done. For robots, harvesting asteroids and/or moon for materials etc. Lot of work, but with potential of supporting trillions of times of current Earth population.

@@tomcollins5112 This is hypothetical, assuming our solar system is destroyed. Also, you are right we should take care of our earth BUT it is already doomed. Even if we turn it into the planet on Avatar where we live in a perfect symbiotic relationship with nature the Earth's clock is ticking. In approximately 5 billion years the sun will expand and consume our planet. Not our problem but if life is to continue we may just be living a space station. By then maybe our descendants have evolved to be boneless and capable of living without gravity. That is a long time from now.
No, Earth is certainly doomed. Eventually our star, the Sun, will reach its end and while it is not large enough to cause a supernova it is estimated that between its red giant phase and white dwarf transition it will expand so much that it will engulf Mercury, Venus and Earth completely, disintegrating the planets. Granted, this is billions of years into the future but our home planet has an expiration date. Sadly.

It seems like orbital cities are probably the only viable option in most future scenarios. While they do require a lot of tech we don't have right now, most of that technology looks like a REASONABLE extrapolation of our current tech. O'Neal cylinders deal with the gravity problem decently, and with sufficient mass they can also deal with radiation. They are pretty big engineering challenges, but they don't appear to require anything exotic beyond some decent materials improvements, and enough advancement in automation that we can bootstrap a substantial asteroid/moon mining economy to get the materials to actually construct stations large enough for our needs (they have to be pretty damn big). Mix in some genetic engineering of humanity and the hundreds of other life forms we'd transfer into these habitats to deal with some of the other problematic aspects of living in space (psychological and physiological), and an improved understanding of cyclic organic environments to build something approaching closed-loop environmental systems, and the concept doesn't look outlandish at all compared to the technology needed for interstellar travel and terraforming. Both of those would require all of these technologies but taken to far greater levels - one that may simply be impossible. The physics needed to move spacecraft at anything greater than 0.01c get pretty exotic (antimatter, ultra-high efficiency fusion), while terraforming requires industry on a scale that would utterly dwarf the idea of building cities in space, on top of an incredible understanding of ecological systems. You could build thousands if not millions of such cities for the same effort as terraforming Mars to be 'Earth like'.

In 1992 The Indiana Institute of technology showed that the technology of the time could build an airship over a mile long, in a flat egg shape. Today though currently not in business Bigelow has shown inflatable structures can be put in space. Then there is the Orbital Assembly Corporation planning to put a large rotating station in orbit using what look like their own version of Bigelow modules. And since the 70's, designers have shown we can make large structures in space. We need never go anywhere, we just need to build better in orbit.
One should point out, with respect to Proxima Centauri b, that if we grant the technology needed to send a spaceship (or fleet) there, carrying human crew numbers totalling in the millions, as would be needed for any "evacuation of Earth" scenario, traveling at speeds up to 20% that of light, then the very same life support technologies we would need to be able to build on those ships to keep the people alive for the journey there would be more than sufficient for dealing with any of the challenges to habitability that the planet might have once we get there, such as its tidal lock, higher radiation rate, and the flare activity of the star, etc. It would be technologically more costly to make Proxima Centauri b livable for the human colonists, and probably life there would never be quite as pleasant for them as life on Earth could be, but these drawbacks may well be offset by the advantages, cost wise, of the proximity.
@@cancermcaids7688Its not about nay saying. Its about getting the practical and actual implementation down. Space travel is well beyond our capability until we have multiple massive technologies. Gravity challenges, human lifespans, radiation shielding, fuel usage, speed, time, food and water recycling, human side effects in long durations off planet, etc... It's immensely irresponsible to just say "innovation" It took humanity thousands of years before we got in flight travel and basic technology advanced enough to even look into space with real detail. It's not going to be anytime soon. And that's if it is even physically possible to solve the challenges that come with space travel and space effects. There is a finite limit to a lot of things in the universe. That applies to speed, and basic survival of organic creatures like us that depend on very specific environments to survive. Some of that may not be possible and not many people want to take into account the limitiations of the universe itself has. And all that has to happen before we 1. Run out of resources on Earth to achieve it. 2. Kill off the planets habitability. or 3. Die to natural world, or spacitial events of mass extinction. Much as we like to pretend we control nature, the truth is we've just been very lucky that we've had a very long duration of relative consistent weather and few major events that could wipe out the planet.
@@SmartAss4123 I mean, yes and no. There is more radiation in space than on Earth, but there's even more radiation on Proxima Centauri B so the same systems may not be enough. Building self contained environmental controls on an airtight ship is also very different than environmental controls on an entire, open air planet.
thing is, even if we terraformed mars and only earth was destroyed, that would still be enough to screw us in the long run, because taking an entire planet out of the solar system would completely mess up the alignments of all the planets gravitywise. who knows how that would all change, the asteroid belt might be pulled towards the planets creating a hailstorm of deadly meteors, or mars could be knocked out of its orbit, its not good either way.
Kevin, My dude. You write some awesome scripts, but sometimes though you can miss some pretty obvious points. If humanity were faced with this kind of problem, The only option would be to build an automated ship with some kind of intelligence, It'd have to be smart, Then fill the ship with human embryos and as samples of as many of earths life as possible and send that on a 100000 year ride that eventually ends up back at earth. Why find a new planet when we already have a good one right here? The advantage of this method is you arent limited to earth if it doesnt work out, All the ship needs to do is boost out of earths gravity, Do a couple gravity assists to get some speed, and yeet itself out to option #2.
Inhabiting any planet around a red dwarf would in many cases be a bad idea. Red dwarfs generally tend to be far more unstable. Producing many magnitudes of order larger and energetic solar flares. Flares that earths magnetic field wouldn't be a to withstand. A habitable planet capable of providing a stronger enough magnet field would have to be either denser or larger with a solid surface. Unfortunately increasing its gravity... 🤔😜
Need to find a planet thats similar to earth, with a good size and age star, in the habitable zone, not tidally locked, in a stable solar system preferably with planets that shield us like jupiter, has to have water, a sattelite similar to the moon, a funtioning spinning core/magnetic field etc
If you are talking something like climate change I think a large cluster of O'Neill Cylinders in orbit would be our best bet. It would be close enough to earth to still use some of its resources and not actually living on the surface of the planet may eventually allow the planet to recover a bit.
At the moment, everyone is basically screwed. There is no way off of the Planet regardles as to if there is a place to go to in the first place. And you can blame NASA for this too.
I heard the mid atmosphere of of Venus was the best and closest off earth environment - temperature mild, gravity good - might be hogwash but I would like to know
suprised there wasnt something allong the lines of oneil cylinders mentioned as part of living in space at the end. gravity can be prety much replaced by simply spinning. they wouldnt require any new technology we dont already have just an insane amount of of construction in space
I don't think we will be able to live on another planet, even if there is breathable air. We were born of this planet and all of it's microbiology and the microbiology of another planet could be dangerous or even deadly to us.
@Cancer McAids I never watched that show. The Quarians have no planet to call home and their entire race lives on giant spaceships that travel space together as a fleet.
@@MrNH718 It's basically the same thing -- in Battlestar Galactica, the Cylons destroy the worlds of humans, forcing them to flee aboard a fleet of refugee ships to what is now a mythical homeworld called Earth.
@@MrNH718 The original from the 70's is pretty dated visually, but it's still a fun watch if you don't mind that. Even with the dated sets and FX, the storytelling is still pretty good imho! The remake they did in the early 2000's still holds up well, but it was a bit more soap opera-ish, with more character-driven drama -- should still be a pretty good watch tho! Everyone has a different preference, so I'd suggest just watching a couple episodes and seeing if it's to your liking :)
As a bit of morbid optimism, I’m glad that at least I’m likely to be dead before the need for a new planet is. Because omg do we have problems, not the budgets to figure them out, but alllll the problems
@@ThatWriterKevin Given that water births are a popular thing, an enclosed tank for space births would be needed, then the water drained and filtered for other uses.
One consideration for colonizing another planet hasn't been mentioned. Let's say we find an exoplanet that has almost everything we need. Almost the same size as Earth, in the habitable zone, it has an atmosphere similar to ours and a magnetosphere good enough to protect us. And we are able to solve the problems of getting there, such as having enough food and water and artificial gravity. We arrive there after a long journey to discover the planet is already populated by a diverse array of life including at least one intelligent species. What would we do? Go ahead and colonize it, indigenous species or not? Turn around and head back to Earth after some exploration and maybe greeting the inhabitants? After such a massive endeavor to travel to another planet would we easily accept not being able to occupy the world and make it our own?
We know how fast it rotates around its star (orbits), hence the number of Earth days in a year. We do not know how fast it rotates around its axis, though it is unlikely to be tidally locked.
I wouldn't want to either, but we've been proven to be able to survive indefinitely at 1.8 Gs and data suggests 2.0 should be possible as well. If it's that or death, then I mean...
Here's the issue. Even if we find a planet that is the right size (so gravity won't fuck you up) has a good magnetosphere (so radiation won't fry you) has all the elements we need to survive and that is reachable in a reasonable span of time... *Still* no guarantee that it is habitable at all. The earth was hostile to life for most of its existence, it stands to reason other planets would as well, even if the other factors are in place. Considering most plants are barren rocky worlds with supervolcanoes, ice ages and other such life-ending environments, the elements of life supporting factors being present does not guarantee a given planet actually suppoets life.
@@bigcity2085 Yeah it's pretty silly but not really for our detection ability reason. Its more about the assumption that since the universe is about 10 billion years older than our solar system and if intelligent life was common, surely someone would've colonized the entire Milky Way by now, including our solar system, since it would only take about 10 million years for a civilization capable of travelling at even just 10% of lightspeed.
Been watching videos about the kardashev scale, were still no were close to moving to the first level that requires mastering the resources of our own planet and the problems that confront us are more than just tech our society as a whole has to change and in truth is the biggest hurdle.
Well, IF the concepts of hyper sleep and a ship that is automated with the protection and life sustaining proticalls could be developed, that could be bossible.
Neutrino storms! Supernovae within a thousand light years, the collapsing of our Sun, a black dwarf star floating out there like the Nemesis hypothesis...
Even if we travel 25% of light it would take longer than 16 years. We cant accelerate instantly to that speed and we can't go from 75,000km/s to 0 instantly. It will take equal amount of to reach that speed and decelerate to 0....
Hears an idea that I think bears merit: We don't leave at all. Instead, we go the Matrix route of building underground cities and learning to live down there. Transporting air, food, and water below ground is MUCH easier than getting it into space. There's plenty of room, so long as we dig. We wouldn't have to worry too much about air and water, because we can recycle it as long as we have a ready supply to begin with, and we're pretty good at building greenhouses, so figuring out how to grow all of the food we need via hydroponics, as well as stuff like trees even, is very attainable. In fact, I'm pretty sure we could readily do that if we wanted to. We've already got a decent bit of practice with it, in regards to Cold War Doomsday shelters. Some of those are self-sufficient for years at a time, and that was with 60s-level technology.
Maybe we just..."Save the Surface "...( we could trick all the global warming deniers , if we just change the name !) - Brilliant ! ....Then everyone just turns in their nukes and ....aah jeez, might as well start digging tomorrow. There's a bizarre old book about going underground called "Level 7". Doesn't sound fun. Actually Finland has huge underground shelters; they can hold more than their population in some places. Leave your pets at the door ,though.
The twinky soundeffects every time a new graphic pops in or out need to be dropped - they detract from the narrative which is the whole reason we come to these channels.
Why is the earth doomed....Earth will still be here, minus us. Crazy thing is after we're gone, the earth will repair itself, in a matter of 3,4 decades...
I just started thinking after opening this video, we probably don't have enough fuel to send people to space in general, right? To think how much fuel is needed to shoot like 3-4 astronauts out there and how massive the ship is in comparison to the personnel on it. Compared to a car for example. So imagine having those ratios applied to all people on the planet. Some people better start considering slowing down climate change after all.

One should point out, with respect to Proxima Centauri b, that if we grant the technology needed to send a spaceship (or fleet) there, carrying human crew numbers totalling in the millions, as would be needed for any "evacuation of Earth" scenario, traveling at speeds up to 20% that of light, then the very same life support technologies we would need to be able to build on those ships to keep the people alive for the journey there would be more than sufficient for dealing with any of the challenges to habitability that the planet might have once we get there, such as its tidal lock, higher radiation rate, and the flare activity of the star, etc. It would be technologically more costly to make Proxima Centauri b livable for the human colonists, and probably life there would never be quite as pleasant for them as life on Earth could be, but these drawbacks may well be offset by the advantages, cost wise, of the proximity.
easier said than done
@@cancermcaids7688Its not about nay saying. Its about getting the practical and actual implementation down.
Space travel is well beyond our capability until we have multiple massive technologies.
Gravity challenges, human lifespans, radiation shielding, fuel usage, speed, time, food and water recycling, human side effects in long durations off planet, etc...
It's immensely irresponsible to just say "innovation"
It took humanity thousands of years before we got in flight travel and basic technology advanced enough to even look into space with real detail.
It's not going to be anytime soon. And that's if it is even physically possible to solve the challenges that come with space travel and space effects.
There is a finite limit to a lot of things in the universe. That applies to speed, and basic survival of organic creatures like us that depend on very specific environments to survive. Some of that may not be possible and not many people want to take into account the limitiations of the universe itself has.
And all that has to happen before we 1. Run out of resources on Earth to achieve it. 2. Kill off the planets habitability. or 3. Die to natural world, or spacitial events of mass extinction.
Much as we like to pretend we control nature, the truth is we've just been very lucky that we've had a very long duration of relative consistent weather and few major events that could wipe out the planet.
@@SmartAss4123 I mean, yes and no. There is more radiation in space than on Earth, but there's even more radiation on Proxima Centauri B so the same systems may not be enough. Building self contained environmental controls on an airtight ship is also very different than environmental controls on an entire, open air planet.
@Kevin Jennings You wouldn't be in the open air on a radiation saturated planet. You'd be deep underground.
Me, Imma move into the Blazement. Save me some of those "special" basement mushrooms Danny, Kevin, etc🍄😵💫
Sadly, the Blazement is also contained on Earth
Video upload is broken. I can't watch it past about 2:51, and I've tried for two days now.
Hey Simon, read a book called Rendezvous with Rama, and extrapolate......
thing is, even if we terraformed mars and only earth was destroyed, that would still be enough to screw us in the long run, because taking an entire planet out of the solar system would completely mess up the alignments of all the planets gravitywise. who knows how that would all change, the asteroid belt might be pulled towards the planets creating a hailstorm of deadly meteors, or mars could be knocked out of its orbit, its not good either way.
Larry Niven solved all those problems with ringworld. 😅
Looks like we need Earth.
Kevin, My dude. You write some awesome scripts, but sometimes though you can miss some pretty obvious points.
If humanity were faced with this kind of problem, The only option would be to build an automated ship with some kind of intelligence, It'd have to be smart, Then fill the ship with human embryos and as samples of as many of earths life as possible and send that on a 100000 year ride that eventually ends up back at earth. Why find a new planet when we already have a good one right here?
The advantage of this method is you arent limited to earth if it doesnt work out, All the ship needs to do is boost out of earths gravity, Do a couple gravity assists to get some speed, and yeet itself out to option #2.
Sidonia is a nice generation-ship. When not being attacked by aliens.
Luckily, we haven't detected any gauna, so it could work,
either that or a Space colony would do the trick
The sound is really low relative to your other videos
Inhabiting any planet around a red dwarf would in many cases be a bad idea. Red dwarfs generally tend to be far more unstable. Producing many magnitudes of order larger and energetic solar flares. Flares that earths magnetic field wouldn't be a to withstand.
A habitable planet capable of providing a stronger enough magnet field would have to be either denser or larger with a solid surface. Unfortunately increasing its gravity... 🤔😜
We actually do have HoloDecks that are physical in world objects, they are just in extremely early development
Now, if it is so far away, how do they ship those book cases to Ikea?
Need to find a planet thats similar to earth, with a good size and age star, in the habitable zone, not tidally locked, in a stable solar system preferably with planets that shield us like jupiter, has to have water, a sattelite similar to the moon, a funtioning spinning core/magnetic field etc
If you are talking something like climate change I think a large cluster of O'Neill Cylinders in orbit would be our best bet. It would be close enough to earth to still use some of its resources and not actually living on the surface of the planet may eventually allow the planet to recover a bit.
i would like to see a video about a tingworld it is a inresting concept i belive
At the moment, everyone is basically screwed. There is no way off of the Planet regardles as to if there is a place to go to in the first place. And you can blame NASA for this too.
Fuckin' hell, Simon. How many channels do you have?
He has 13 channels.
Proxima Centauri B is a Flare star so its probably been drained of life
Oh, Simon, that grampa geezer sweater sgain?
I heard the mid atmosphere of of Venus was the best and closest off earth environment - temperature mild, gravity good - might be hogwash but I would like to know
Make the most of Now, that’s all we have.
suprised there wasnt something allong the lines of oneil cylinders mentioned as part of living in space at the end.
gravity can be prety much replaced by simply spinning.
they wouldnt require any new technology we dont already have just an insane amount of of construction in space
How many channels can one man have?!
Yes.
Legally, or successfully?
Do you count an army of clones as "one man?" :P
14
There is no way to move people off of earth and sustain life somewhere else, period. This is it people
I don't think we will be able to live on another planet, even if there is breathable air. We were born of this planet and all of it's microbiology and the microbiology of another planet could be dangerous or even deadly to us.
I agree
👋 Hi Simon
Barnards Star in an O’Neil cylinder powered by project Orión…. Seen in on UA-cam right here 😂😂
I love all the goofy animations
Sometimes, you just need a ride....from someone who knows how to travel, better than you do.
You assume we would react in time to respond to such a situation…
Speed reading Simon?
If we can wait for the sun to expand there's a good chance some of the moons of the other planets will become a lot like Earth so theres that
Io perhaps?
@@Thurgosh_OG Perhaps Europa and Enceladus as well?
Use the Quarians from Mass Effect as an example. Everybody just live on ships.
@Cancer McAids I never watched that show. The Quarians have no planet to call home and their entire race lives on giant spaceships that travel space together as a fleet.
@@MrNH718 It's basically the same thing -- in Battlestar Galactica, the Cylons destroy the worlds of humans, forcing them to flee aboard a fleet of refugee ships to what is now a mythical homeworld called Earth.
@@olencone4005 interesting.
I heard it was a good show for its time. You recommended watching it today?
@@MrNH718 The original from the 70's is pretty dated visually, but it's still a fun watch if you don't mind that. Even with the dated sets and FX, the storytelling is still pretty good imho! The remake they did in the early 2000's still holds up well, but it was a bit more soap opera-ish, with more character-driven drama -- should still be a pretty good watch tho! Everyone has a different preference, so I'd suggest just watching a couple episodes and seeing if it's to your liking :)
I hope your fingers alright Simon.
As a bit of morbid optimism, I’m glad that at least I’m likely to be dead before the need for a new planet is. Because omg do we have problems, not the budgets to figure them out, but alllll the problems
Imagine the mess of giving birth in 0g.
Procreating in 0g is enough of a visual, I don't want to even think about the actual birth.
@@ThatWriterKevin Given that water births are a popular thing, an enclosed tank for space births would be needed, then the water drained and filtered for other uses.
One consideration for colonizing another planet hasn't been mentioned.
Let's say we find an exoplanet that has almost everything we need. Almost the same size as Earth, in the habitable zone, it has an atmosphere similar to ours and a magnetosphere good enough to protect us.
And we are able to solve the problems of getting there, such as having enough food and water and artificial gravity.
We arrive there after a long journey to discover the planet is already populated by a diverse array of life including at least one intelligent species. What would we do? Go ahead and colonize it, indigenous species or not? Turn around and head back to Earth after some exploration and maybe greeting the inhabitants?
After such a massive endeavor to travel to another planet would we easily accept not being able to occupy the world and make it our own?
If you don't know if Billy is tidally locked. How do you know how fast it rotates, if at all?
We know how fast it rotates around its star (orbits), hence the number of Earth days in a year. We do not know how fast it rotates around its axis, though it is unlikely to be tidally locked.
Hollow out asteroids is what I would go for.
1.9 times? Yeah, don't think I really want to weigh 400lbs, lol
I wouldn't want to either, but we've been proven to be able to survive indefinitely at 1.8 Gs and data suggests 2.0 should be possible as well. If it's that or death, then I mean...
True, but how much weight would you lose on the trip?
I've noticed a change in the editing. There's a lot more graphics, and it really works well.
Grandma's house we go. Smells good and she makes the best cookies!
Wait when did Simon make this channel
Here's the issue. Even if we find a planet that is the right size (so gravity won't fuck you up) has a good magnetosphere (so radiation won't fry you) has all the elements we need to survive and that is reachable in a reasonable span of time...
*Still* no guarantee that it is habitable at all. The earth was hostile to life for most of its existence, it stands to reason other planets would as well, even if the other factors are in place.
Considering most plants are barren rocky worlds with supervolcanoes, ice ages and other such life-ending environments, the elements of life supporting factors being present does not guarantee a given planet actually suppoets life.
Oh a new Simon chanel
I would hope that by the time we've got interstellar travel figured out, we'd have obesity fixed.
1800 years is enough time for a planet not to exsist
Good point...when all you see is light speed; you're essential deaf and blind. Which makes the Fermi paradox...silly.
@@bigcity2085 Yeah it's pretty silly but not really for our detection ability reason. Its more about the assumption that since the universe is about 10 billion years older than our solar system and if intelligent life was common, surely someone would've colonized the entire Milky Way by now, including our solar system, since it would only take about 10 million years for a civilization capable of travelling at even just 10% of lightspeed.
What do you mean we can't move people away in great masses? I thought we are already on our way to Mars...
If ya wanna see a show about civilization living aboard a space ship for generations, check out The 100.
Been watching videos about the kardashev scale, were still no were close to moving to the first level that requires mastering the resources of our own planet and the problems that confront us are more than just tech our society as a whole has to change and in truth is the biggest hurdle.
Well, IF the concepts of hyper sleep and a ship that is automated with the protection and life sustaining proticalls could be developed, that could be bossible.
it would just be easier to build floating cities in Venus's atmosphere. "easier"
If we have the tech to travel to another solarsystem, why do we need to live on a planet? Wouldn't a rotation space habitat do the job?
Neutrino storms! Supernovae within a thousand light years, the collapsing of our Sun, a black dwarf star floating out there like the Nemesis hypothesis...
Even if we travel 25% of light it would take longer than 16 years. We cant accelerate instantly to that speed and we can't go from 75,000km/s to 0 instantly. It will take equal amount of to reach that speed and decelerate to 0....
Well this should be fun.
You're telling me he has yet another channel?
Hears an idea that I think bears merit: We don't leave at all.
Instead, we go the Matrix route of building underground cities and learning to live down there.
Transporting air, food, and water below ground is MUCH easier than getting it into space. There's plenty of room, so long as we dig. We wouldn't have to worry too much about air and water, because we can recycle it as long as we have a ready supply to begin with, and we're pretty good at building greenhouses, so figuring out how to grow all of the food we need via hydroponics, as well as stuff like trees even, is very attainable.
In fact, I'm pretty sure we could readily do that if we wanted to. We've already got a decent bit of practice with it, in regards to Cold War Doomsday shelters. Some of those are self-sufficient for years at a time, and that was with 60s-level technology.
Maybe we just..."Save the Surface "...( we could trick all the global warming deniers , if we just change the name !) - Brilliant ! ....Then everyone just turns in their nukes and ....aah jeez, might as well start digging tomorrow. There's a bizarre old book about going underground called "Level 7". Doesn't sound fun. Actually Finland has huge underground shelters; they can hold more than their population in some places. Leave your pets at the door ,though.
Only works if the Earth isn't about to be destroyed by a giant asteroid or rogue planet. Going underground won't help there.
City lights or WMD silos
Well, Simon, you better hope we figure this issue out. If you're going to be immortal then one day you will see the Earth be destroyed.
O'Neill cylinders. D'oh!
We could never get off a planet bigger then earth though
With current tech... we'd just be f'ed.
That's why it was set in a theoretical distant future where long distance space travel was possible
The twinky soundeffects every time a new graphic pops in or out need to be dropped - they detract from the narrative which is the whole reason we come to these channels.
we can live without planets
planets are an experience
we can live in whatever experience we imagine ourselves within
no cookie, no crumbs
How about Pandora? 😏
Why is the earth doomed....Earth will still be here, minus us. Crazy thing is after we're gone, the earth will repair itself, in a matter of 3,4 decades...
I just started thinking after opening this video, we probably don't have enough fuel to send people to space in general, right? To think how much fuel is needed to shoot like 3-4 astronauts out there and how massive the ship is in comparison to the personnel on it. Compared to a car for example. So imagine having those ratios applied to all people on the planet. Some people better start considering slowing down climate change after all.
Space Elevators could be used but lets be real here, only the rich and powerful would get to go.
