Just to be safe from a major supernova, t'would be best to spread into at least one neighboring galaxy.
Even better would be to annex a couple of spare rooms of the Multiverse.
Doesn't do much good to spread one's eggs into multiple baskets, then leave them all sitting on the same rickety table.
True. I try not to think about super novas. There is enough to worry about as it is. I wish I could live to see the day we travel to another galaxy but unless there are some major breakthroughs in medicine, or physics, I don’t see that happening.
