I think I just blew your mind.
Again, there was a big bang. The resulting universe is expanding outward.
Photon is right to say that if I took a long walk around the outside of our universe I'd end up in the same place, the North Pole, because I'm walking on a bubble.
That's not what I'm asking about.
The universe is expanding into an emptiness. Or empty as far as we know.
Even as I stand stationary at the North Pole of the Universe, I would be moving outwards into this empty space because I'm standing on the bubble of the expanding universe.
So, what am I moving into?
How far does "nothing" extend?
Are there other big bangs and other expanding universes, in this dimension, also expanding outward into nothing? Perhaps closing the gap with our universe as an example.
Do universes, like galaxies, eventually collide? Is it just a bigger example of something that already seems collossally large in scale?
What lies beyond our universe, in this dimension?
I'd love to know how far "nothing" really goes. How big is nothing? And, come to think of it, what lies beyond "nothing?"
