Starting from any point in the universe, shine light in all directions; given infinite time has passed, will it have reached the edge of the universe?
It doesn't make sense to me to define the universe as finite, as there is no edge of the universe to cross.
You could imagine the universe shaped like a sphere, and traveling a constant distance in a straight path would eventually get you back to your original position, but still you would never reach the edge of the universe.
At the border of our universe lies a dimensionless quantity.
