I am just putting what my thoughts are
since all finite matter has a center and the universe is finite, that it must have a defined center even if you are on a lake and look around and cant see the shore as a frame of referance, the lake still has a center. Our inablity to find the center does not mean that the center does not exist. If the universe does not have a center then it cannot be finite.

You are standing on the surface of the Earth  a 2dimensional plane with a finite area. Where is the centre of the Earth's surface?

The center of the Earth's surface is not the center of the Earth as a whole. A solid 3d shape like the Universe does have a center. And the center of the Earth's surface could be said to have infinite centers as each point can be reached by going around the Earth, and the path you follow has a midpoint. But as I said, the Earth does have a center. Also, the surface of the Earth can not be made into a 2d shape, the surface of the Earth is also a sphere and the center of the spheres mass would be at the center of the sphere. If you laid the Earth out flat, then it would have a defined center since you would have to chose a latitude or longitude to define as the edge, no matter where you cut a globe and lay it out, you will end up with a center.

If the Universe is not truely infinite would this suggest that there is something else besides the Universe?
I dont mean the observable universe here, I mean the whole Universe which is a continuum of our own observable Universe. By something else I mean more Universes separate to our own or perhaps something in which our Universe is contained in some way.

Some 3D shapes have centres. That does not mean all do. If you go nuts with your scissors and cut the Earth's flattened shape into confetti, then your shape will have straight edges and acute vertexes. Does that say anything at all about the original shape of the Earth's surface before you mangled it? Does it mean "the surface of the Earth has straight edges and vertices"?

Nor does it inandofitself rule out there being something else  but not being infinite does not suggest there is anything else.

Well it is hard to imagine that everything that is or ever can be is finite. There again it is difficult to imagine infinite as well.
It is also hard to imagine that there is any final level of reality or structure, since everything we know of in our everyday life is contained inside or is a part of something else; sub atomic particles, atoms, molecules, planets, solar systems, galaxies, clusters etc.

The mathematics shows us. It is the only accurate model.

And an infinite universe is not the only model, you say this yourself. It's also possible that the universe is finite and unbounded. It's also possible there is an outside to what we currently consider the universe, regardless of whether the model requires it. The moment you consider anything you cannot currently see, you are imagining.

There is nothing imaginary about the math. Get used to it.
