Dear All
As I have understood, there will be only cooling chunks of matter like stray planets, neutron stars, brown dwarves and all other kind of debris left of our Universe in 10^20 years, which continue drifting apart as the Universe expands on (let us assume that it does). They will continue their journey forever if the protons are stable (let us assume that they are).
If some intelligent race built a refuge, it will drift along until it it will run off energy and freeze. The question is, what energy sources will be available by then? It is longer than half-lives of most of unstable elements and I guess that one does not draw much from Bismuth decay anyway. Would it be possible to harvest the background radiation? Any other ideas?
Let us assume that they live in a kind of virtual reality and their energy needs are thus low compared to our present civilization (to keep their computer ticking and maintained).
Thanks in advance.
