I think they would be able to stand all of those. My question was...
Could they survive a nuclear bomb?
In a way, they would be ripped apart and burned, because their molecules would distintegrate.
Also, when the world enters an extreme ice age (trillions of years from now when the universe expands so much, if you saw The Universe episode on the History Channel, you'll get what I mean) would they just stay on Earth forever by themselves. They can't starve themselves to death, so would they be hungry for the rest of eternity?
