When the sun runs out fuel it would expand and die leaving the earth scorched without life and water. Christians would have to build a very “large structure” near the Oort Cloud so they wait out for earth to cool and return to repopulate earth with life via global flood lights and this is when Jesus might return.
PS: I want to call this large structure Stephonia.
I’m assuming you may be offering the above mostly, or at least partly in jest?
There are so, so, so many other planet-altering catastrophes (from our present perspective) that would have happened between now and the sun going all expansive, that … us worrying about the sun would be about like a hiker worrying about how he will scale a cliff still a thousand (makes that billions) of miles away when he has 300 miles of swamps, mountains, and mine fields to get through right now. Neither he, nor any civilization he is a part of, or even just could now futuristically imagine, will ever be reaching that far point.
I’m about 800 million years, photosynthesis will become impossible as carbon dioxide levels fall below the levels needed for photosynthesis to occur. When this happens, most complex life ok Earth will likely go extinct. Unless humans pull some crazy shenanigans, we will most likely follow to be with our Father in Heaven.
800 million years is out of your (and all of our) imaginative reaches every bit as much as billions of years is. We don’t even have the wherewithal to see 8 hundred, or 8 thousand years ahead, much less what you’re talking about.
I’m impressed with any company which at least aspires to appear concerned about repercussions of things to “the seventh generation” (which is less than Two centuries). And most corporations are too idiotic to even care about the next generation, much less several ahead. So it’s laughably abstract to entertain talk of millions or billions.
Second coming is not a jest and neither is Stephonia.
I think WALL E type of space ships will solve a lot of Earthly problems but I feel we (people and animals) will choose be in space more than on Earth (or any other planet). And this will happen much much sooner than you think. Even if given a choice to be on Earth people will refuse to be on Earth.
Earth (or any planet) will likely be a holiday destination than a permanent residence. Humans will orbit is planet than be on it. But when the sun dies Christians will need to repopulate Earth with life (at least animals) and orbit Earth.
Jesus may return at this point.
WALL E type spaceships are not as hard to build as you think. It doesn’t need to look exactly as it does on the outside.
I cannot argue with that. I suppose humanity’s only hope would be to become interplanetary and/or inhabit other stars too, but looking at the bare fact that we give our military far more importance than our space program, this will most likely not go anywhere as well 
Anything is possible in the future but living in space includes such hazards and unnatural conditions that most people will likely prefer living on planets. Space is chosen by the majority only if the conditions on planets turn to life threatening or very uncomfortable.
Human biology is not adapted to life outside planets. We would need a long evolution or gene manipulations to become somehow adapted to such conditions.
I agree that military budget (US) can be used to build large WALL E type space ships that look different on the outside.
I’m optimistic about the future.
With a few innovations that are coming up we will IMO witness the beginnings of a type 2 civilisation.
You will not miss Earth because it will look like Earth in space but everybody’s flying instead of walking. It will be walking that will kill the planet as a residence.
Earth (or any planet) will only be a vacation spot for this reason and you will want to return to your very large WALL E spaceships.
In the future when you do stumble on a plenet you will only use it for resources to make your WALL E type space ships larger than before than to stay on it. Because walking will be the one thing that people will hate the most.
No person on such space ships will ever become fat because of a few things that are coming up. One is called Signal Technology. It will let you perform exercises while you’re sleeping or while you’re sitting and watching a movie for example.
Exciting things are coming up shortly.
WALL E type spaceships will have no hazards except when you’re speeding at .8c.
You will not miss the Earth at all because it would look like a city in zero gravity and you will get to fly like Superman. The only hazard here is that you may bump into another Superman who is flying towards you. Think 20 square km structures.
The list of problems associated with space flights include
Most of those problems could be tackled by building large structures with artificial gravity (space cities). Those structures would need heavy protection from cosmic radiation. Theoretically possible but would be extremely expensive to build and expensive to maintain.
If these cities would stay on orbits around the planet, that would mean additional need of energy for maintaining the altitude and protection against collisions with space trash and space stones.
If the building of a space city costs tens or possibly even hundreds of trillions and the maintenance probably at least tens of millions per year, that will be really valuable property. Only the richest billionaires could afford to live on such space cities. If the space city would cost a hundred trillions (100 million millions), that divided with 100’000 people would be a billion per person. A ‘cheap’ space city that costs only ten trillions to build would still cost a hundred millions per person if the city is built for 100’000 inhabitants.
Walking causes planetary destruction while flying does not?!! You are living in a fantasy world. And even with all our present awareness of bone and muscle deterioration in space, and all the exercises astronauts now do to help mitigate that, I’m pretty sure they still experience bone and muscle loss. Others here can correct or update me on that if that’s no longer true. But I do believe long term space flights are still debilitating to overall health, and not just because of the excess radiation which is also still there.
You are obviously a big fan of the movie Wall-E, so you should pay attention to the climax of the show where the captain must heroically get up out of his ‘Scooter’ to walk across the bridge and push a button. That (and how we trash the only planet we have) are probably the most realistic parts of the movie.
This is absolutely not true. You will be surprised at how inexpensively these WALL E type ships can be built. Exteriors will be minimal.
Space access will shortly be democratised and this will reduce the cost of building these structures in a handsome way.
Building is not the main problem, the problem is to keep the humans alive and healthy inside the space structures. That demands sufficient space, artificial gravity, adequate protection from cosmic radiation and protection against minor collisions in space (major collisions are deadly anyway, so no need to build protection against major collisions). If the structure is not stationary, there is also a need to plan and build the structure so that it keeps the humans alive through accelerations and decelerations.
Building of the International Space Station (ISS) cost crudely 150 billion $. That kind of small and cheap structure cannot keep people alive and healthy for extended periods. When we build something much greater and sufficient for decent long-term life in space, the price will be radically higher.
We may democratise space access but that does not drop much the costs of building in space. Building on Earth is much cheaper than in space but getting very large and heavy structures from Earth to space is so difficult/expensive that building in space or on smaller space rocks or moons becomes the only practical way to build ‘space cities’ that can accommodate 100’000+ inhabitants.
If the building happens in space, we have to first build a space dock that is sufficiently large for the project.
If all the building material is sent from Earth to space, expensive logistics is not the only problem. The growing demand of metals and other valuable materials that may be permanently lost in space will increase the prices on Earth so much that mining of asteroids may be the most cost-efficient solution. That is possible but not cheap or rapid.
Theoretically, all the problems can be solved. It is just expensive and time-consuming.
Anything over 0.08c would be fatal – above that, there is insufficient reaction time between detection of a threat and a response.
But when everyone has city sized spaceships, where will we all park? Besides the PB coaxial coefficient will enhance the harmonics, causing retrograde dynamic vibrations, destroying any ship that tries to go over 0.5 Centipedes.
Not if you cross-calibrate the tachyonic antimatter-injectors with the field-emitter coil, remembering to synchronize the harmonic phase disruption to within the 0.5 Centipede tolerance. Geez. Obvious!
Obvious sure, but that would require maintaining multi-scalar frequency alignment for 5 parsecs in an unstable axion cloud. The temporal rift distortions may exceed specifications for hull integrity.
