However the same is true for any point in space, so the idea of being at the center is relative.
Similar with expansion, there is no true objective center of expansion, its entirely relative. Visually its explained perfectly here: https://youtu.be/W4c-gX9MT1Q?t=9 |
I will be honest: that video didn't help me at all (and many others in the comments apparently too), but in reading the comments I did realize that I had made a mental error in my conception of the big bang. I essentially had space and time existing already, but just empty, and then the big bang was all the matter that exploded in space. But the big bang IS space, time, and matter all co-relative, so the singularity really is the whole universe, including all of space. But since we are limited beings, my brain still has to create a thing called "non-space space" in which to put the singularity in order to make sense of it all.
It still seems to me though, that if we are God "outside" of time and space watching the formation of the universe, then at the point in time that the universe was, say, 1,000,000 miles wide in its expansion, there would be a measurable center 500,000 miles from all edges, which would remain the center even as it all expands to where we are today.
Some say in the comments that the universe has always been infinite, even in the context of the big bang. If that's true, I can't wrap my head around it.
