The scale of existence is mind blowing
To imagine if we had multi-universe clusters too and more (most likely)
Butt to put it into further perspective, we have to look into microscopes to look at the smallest objects known to us. And to those object, or to a bacteria, we would be infinitely big. So maybe we aren't so small anyway.
Butt one thing that is for certain, is that we must start spreading out to the universe. Too dangerous to stay here on this planet. It would be safer to live inside asteroids or other solid planets. We must get there soon, i'm worried. Campi flegri in italy is heatin' up. It only takes the one. It's like playing civilization 2, you get to the end of the game, then lose because one civ gets the upper hand. Just lose it at the end.
I actually remember from one of those programs, "The universe" and such .. the biggest chance we humans have to secure our survival, they said, was to spread our dna (i think it was) as far as possible out into the universe, and hope they land on suitable planets in due time, so we can arise there again. Quite crazy thought.
One of the worst things i know about those scientists, is that they say that the universe will "come to an end" at some point. I don't believe in that. I believe it will continue forever - new universes, as you mention, multiverses. I think the most logical thing, is that we live inside a black hole. Black holes are impossible to understand, it's pure gravity. So what's inside it? Nobody knows. Not a lot of the matter that surrounds them, actually get inside, because they spin around the black hole and cause quasars instead. So that's quite interesting.
