So every physics/astro student is told there is no center of the universe, imagine it like a balloon and every point expands equally from every point.
Except, there is a center of a balloon. Right in the middle where the air is. The universe isn't the flat surface of a balloon, it is 3 dimensions and expands in 3 dimensions.
Now, if we are measuring from Earth, and pick a direction, there must be a galaxy out there that is the farthest from Earth. Unless space curves completely back in on itself. There is some debate about that. Now, this galaxy is likely too far for us to actually ever see, but it exists.
And if we measure in every direction, there should be similar 'farthest galaxies'. The distances to these farthest galaxies won't necessarily be the same. But there should be a point in space where the distance to these 'farthest galaxies' is roughly the same in all directions. That point would then be the center of the universe.
I'm sure this has been thought of and holes poked through it, but I'd like to hear others' thoughts.
