This is actually one of the most optimistic possible outcomes for our universe that scientists have put forward. Before the two basic models were:
1) The universe will continue to expand until everything is so for apart that for all intents and purposes there will be nothing in the entire universe.
and
2) The universe will collapse in on itself and either stay that way or re-big bang.
Edit: there are more but I'm not going into all that, there's just too much going on and I'm a bit rusty on some of this stuff.
In my opinion this model is much happier than either of these. Just imagine that humanity manages to outlive Earth; that we or some other form of life manages to endure and make it to the creation of a new universe. The expansion would be incredibly slow. Light years are nothing when you consider the size of the universe, and it will be much bigger by the time anything like this could happen. Now think of all the advances to technology in the past few decades. Imagine what kind of technology might exist a few billion years from now if someone/thing somehow manages to survive. If you can imagine this far, it's not that much of a stretch to imagine that just maybe some form of intelligent life would be prepared and possibly find a way to move from the old universe to the new.
It's a long shot but if this theory is true we just might have a chance of avoiding the complete extinction of every species that ever has or will exist anywhere in the universe. That's more than we had before, and that makes me happy. Please tell me if you have relevant information on any of the ideas I have put forward. I'm not a professional scientist, just an enthusiast, and I could have something wrong.
