Re: No way to get solar energy by then...
I think the suggestion was to move the earth itself to a new solar system.
As long as we could live on the heat stored inside the earth for 8,000 years (a blink of the eye in earth history), and continue to breed, surely it doesn't matter if it takes that long to reach the next star?
Obviously, accelerating the entire earth to that speed would be quite an undertaking. We may have to throw off quite a lot of mass to achieve it.
