Short but so true! We really seem to be connected by history. And I also think it's true that this kind of enlighenment can make our individual deaths less dramatic.
One of that same theorys most popular end game is something called heat death though. Something that supposedly would make it impossible for life or any kind of Work in the physical meaning. This due to the universe reaching its thermodynamical equilibrium or maximum entropy.. I for one likes sci-fi too much to actually believe that this would be impossible to escape though.
Personally I've grown quite attached to us. The universes, as far as we know, only thinking and feeling parts. Sadly, I think that we're more likely to go extinct before colonizing another planet than by this heat death. And that scares me more than my own death. I'm still optimistic though, just not safe enough yet. Hope you don't mind me sharing a lot of personal thoughts.. Thank you for yours!
