If I understand the big bang theory correctly our whole universe was in a hot dense state. And then suddenly, rapid expansion happened where everything expanded outwards presumably from the singularity. We know for a fact that the universe is expaning and has been expanding since it began. So, theoretically if we go backwards in time things were closer together. The more further back we go, the more closer together things were. We should eventually reach a point where everything was one, or where everything was none (depending on how you look at it). This point should be the center of the universe since everything expanded from it. But after doing a bit of research I have discovered that there is no center to the universe. Please explain to me how this is possible.
Thank you!

Imagine an infinitely long rubber band, going infinite in one direction and infinite in the other direction (as far as we can tell). This rubber band has been stretching for as far back as we can see, so like you said, you can imagine a time when it was at its “shortest” and densest. Except even when this rubber band was at its most compressed, it was still infinitely long (as far as we can tell).
It’s like that, except in all three dimensions. Even when space was at its densest, it was still infinite in every direction (as far as we can tell).
Space inflated everywhere all at once. Or another way to imagine it would be to think that everything in space shrunk in place all at once, and we are still shrinking in place, technically making everything farther away from our smaller perspective.
