If the universe is expanding...?

That future is very far away; the universe isnt even anywhere close to half dead yet. Hardly worth worrying about.Mankind will be long dead and gone way before that.The sun, though, is a good half-way through its lifespan,......

Yes. We may evolve, we may attain the stars, we may develop really good shields. But more than anything we need to learn to work together.

"So from what i am reading in the comments, either everything comes to a close and starts up again, or if we can't survive, we are dead and that's the end of it all?"

One thing at a time. It is possible that we can drop across the event horizon of a supermassive black hole, and witness the birth of a new Universe...

It appears that we live in a universe destined to expand continuously. Entropy will eventually succeed in removing all semblance of order or structure and leaving everything cold, cold, very cold. You could think of it as the energy being spread out way too thin to fill the space that exists. That future is very far away; the universe isn't even anywhere close to half dead yet. Hardly worth worrying about. Mankind will be long dead and gone way before that. The sun, though, is a good half-way through its lifespan, so this solar system will cease to be in a few billion years or so.

It is a depressed question.

It is one scenario, called the big chill.
Another scenario is if gravity takes over and the Universe retracts back to the big crunch!!
( Bounceback maybe!).
The third scenario is the steady state where it reaches a gravitational equilibrium and everything just goes on as usual.
A lot of time may be covered, and if say we became self sufficient enough, we could make enough of our own resourses to survive though.

The universe can support life for about another 30 billion years, which will be nothing in the grand time scale of the universe. If that seems a little depressing to you, remember that for a large chunk of time, the universe couldn't support life at all. It was too hot, there weren't enough building blocks for life (all of the carbon, nitrogen, etc....) and it's only really recently that the universe has been able to sponsor life at all. That means that right now, we're still in the infancy/toddler stage for life in the cosmos. Life has a long time yet to flourish and expand throughout the stars.
