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 the universe is on the surface of a balloon. Add a dot to any place on the balloon. That dot is you.
Any direction you head is continuous without any sort of end to it. You will eventually loop back to where you started but that starting point is just a random point on that surface.
Because there are no defined boundaries, there is no center (there is no start or end either).
You can inflate the balloon which will increase the distance between your dot and any other point on the balloon, but the surface remains continuous and without any boundary or any center.
That’s the simplest explanation I can give without getting into a poor explanation of things like space manifolds. 🙂
