How can the universe not have a center?

1.81K 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!

Let’s scale this down.

Take a perfect circle, point to the center, easy.

But where would you say the EXACT center of New Zealand is? Is it even possible for something of that shape to have a center? We can theorize on where that point may be. Math can help, but it’s hard to know for sure.

Now scale that up to an ever expanding object that we can’t even visually see the full scale of. Again, math can help, but it’s difficult to know for sure. And from HOW we observe, we’re looking out from the central point of a location, but that doesn’t necessarily mean the object we’re observing is a circle, square, triangle, rhombus etc. Yet we already know that we’re looking from a point that isn’t dead middle of the shape.
