My question is about space and the multiverse. I was reading work by Max Tegmark and he sees the multiverse as Level 1-4. A Level 1 multiverse seems like it's self evident and I was wondering about the evidence against it. It's simple:
Space expands faster than we can observe it so we exist in a pocket or bubble universe that's simply a sphere determined by the speed of light in every direction. So our observable universe is just limited by how far we can see in any direction.
If you go to a galaxy a billion light years away, couldn't you say it's observable universe is a sphere that's determined by the speed of light in every direction from that point and will include space outside of our observable universe.
Wouldn't there be an infinity of the sphere's or pockets as space expands? Does space end because we can't observe it?
Just curious.
