Turns out, no; every point is expanding away from every other point, so every point sees itself as the center of expansion.
That could sort of explain why it's inherently impossible to determine the center - but that doesn't rule out the existence of a geometric center of the universe, right?
Kiiiind of. I suppose we haven't definitively ruled out a geometric centre, but it runs up against Occam's Razor in a really big way. A centre of the universe would require some kind of boundary or edge to the universe, and the physical dynamics of how that would even work are very much non-trivial.
Generally the universe is thought to either loop back on itself like the surface of a globe, or extend infinitely in every direction.
For a geometric center you would need a boundary of the universe
