A mute point since we cannot as of yet escape a star going nova.Can you name any other beings able to do that?
Perhaps we could leave our solar system. That would be part of solving the problem. Up until we can solve that problem in practice then we are just another species trapped in a doomed Solar system. If humans as a species die in a nova event then we are equals with all of the other species that died with us. We have a long way to go before we rise above our co-inhabitants of this solar system. After all many humans still believe in folktales about mythical creatures and magical superbeings. And those primitives that need to think that one species is more important because of their luck with evolutionary advancements.We are important because we are the only ones capable of reaching that. Besides...we can leave the solar system.
But it is most likely that humans will be long gone before the sun goes nova. Perhaps the species that evolve after us will step up and save the solar system from its eventual doom?
