How can the universe not have a center?

1.79K viewsOtherPhysics

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!

The way I interpret it (and I’m in no way an expert), to determine the “center” of something you have to know where the edges/limits are. As far as we know, the universe is infinite and has no limits. Thus impossible to triangulate a center.

Regarding your second point about going back in time to the Big Bang, space & time (as we understand them) didn’t exist before the Big Bang. So it’s impossible to point to the center of something that doesn’t exist
