That's really cool, but by the time our red giant sun wipes out more than half the solar system, I think we will have already wiped ourselves off the face of the earth long ago or some other outside source, like a large asteroid, will. Sometimes I wish our sun was big enough to become a black hole, but it will only become a small white dwarf when it dies. I think we might be able to make it Mars (Mars will get wiped out by our red giant sun too though) and possibly other planets but never a planet as far as 581c.
