How can the universe not have a center?

1.90K 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!

You are correct your thought process but you run into the “trap” a lot of people run into. You imagine the big bang as a single point where everything started like a bomb. This isnt true, the big bang happend everywhere, everywhere was just much closer together and thus matter was also much denser but the universe still was infinite. This is confusing because most people think that something that is infinite cant become bigger but it can.
