This unfortunate fate will inevitably confront us in less than a billion years, when the sun will heat up enough to boil all water off the face of the Earth. With proper planning we could relocate to a new home by then.

How friggin' profound...

In a billion years, if we are still around, I’d say we will have mastered interdimential travel and can go anywhere in the universe in an instant.
We’ll probably be creating stars at that point. So we’ll have a new one in waiting when the old one is ready to retire or we’ll just give it a quick charge to last another 5 billion years.
