spaceships for human survival
Is it possible that humanity could survive in space if earth became uninhabitable?
Stupid way to ask the question.
(actually the question is several kinds of stupid).
By definition it is impossible to "stock anything with endless infinite amounts" of anything, including food.
A better way to ask would be to say "can we build space ships that are self sustaining", and can grow their own food crops (of algae maybe)?
Its easier to keep the earth habitable than it is to put the whole human race into a space ship.

The best option is terraforming again, so we could terraform the earth again, or just hope not to destroy the next one

If you're gonna talk about it then ... really speak. And explain what it is that you're speaking about.
Do you mean force the whole human race into space life boats, and abandon ship on the whole planet? Launch all seven billion of us into space?
Obviously impossible.
Or do you mean just take a select few, like in Noah's Ark, and send those few into space (allow the rest of us to perish but those few could carry on the human linneage)? These select few could be like a small city of thousands, but would still be tiny portion of the global population.
That would be more feasible.
But even then...what do you mean?
Do mean send this huge space craft with this select community of survivors out to find and colonize a new planet ?
Or do you mean have them just live in space for ever?
I was more thinking of sending a small minority of people like you said.
Not sure how many spacecraft would be involved, but maybe a mothership and then smaller ships for individuals.
I was thinking not to colonize other planets, just live in space using supplies from the energy ship.
I'm told it's infeasible though.
At some point in the future it will probably be possible. Most things that can be imagined can be done with enough knowledge, resources and experience.

Aye, that one is particularly relevant. It describes the Exodus Fleet, where humans have been living for dozens of generations. The key is to recycle everything, from broken tools down to corpses.
Barring the invention of a Super Futuristic Magic Space Drive, you're still going to need reaction mass for your engines. One idea I've seen a few times (e.g. "Hull Zero Three" by Greg Bear) is to attach the ship to a comet and feed comet material into your engines. The comet is used up by the time you reach your destination.

so wait is it theoretically possible to put a space ship behind a comet someday in the distant future.I thought that was only sci-fi but maybe I will be proven wrong one day.

The only space ship we've got is the planet we inhabit.

You already live on a space ship that follows a star around like a pug dog shadows its master. Its a natural space ship called "earth", and it orbits the Sun, while the sun itself cruises around the galaxy.
We can already put manned, or unmanned space vehicles upon, or in orbit around, or "behind", any celestial object in the solar system you want with technology we have today. We have landed men on the moon, and have sent probes out to every planet, and to go up close to asteroids.
Nothing special about that.
So we could wait for Halleys comet to return, and then send an unmanned probe, or even human astronauts, behind it to follow it back out to the outer part of its orbit billions of miles out, and then follow it back in again when it returns seventy some years from now. But there is no reason to do that.
But we cant do yet is "mine" asteroids, or comets, for their mineral resources yet. But that might well be possible in the future.

I dont trust the idea of going behind a comet for decades to escape planet earth because I came close to becoming a orphan from Heaven's Gate even if it is theoretically possible.
Timothy Leary talked about this in late 1970s.

OMG!
Your parents were involved in the infamous Heaven's Gate Cult????
That was in the like early Nineties. If my memory serves. Was in the news. We all talked about it, and comedian Richard Belzer joked about it.
you're right...it was a suicide cult, and even if your parents hadnt offed themselves they might have...um..neutered themselves (thats what the cult members had to do). Either way you wouldnt be here now.
Yeah...I remember how the cult leader had himself, and his followers, convinced that there was a space ship following Halley's Comet into the Solar system, and that that spaceship was going to rescue them from earth. And it all hit the news when the police found them all lying dead around the guys house from mass suicide. Glad your family survived all of that insanity.
