Let’s talk about left and right. doesnt matter which way you look at it. front view or side. 2d or 3d model . Left is right & right is left if you go in one direction for a far enough distance on a specific plane. traverse Left or right far enough wraps around the entire fabric of the universe and comes back together eventually.

If the left or right is faster than the expansion of the universe it will wrap back together if the expansion of the universe is faster than the rate at which the left or right is moving than the only way for the two directions to meet is a worm hole where either direction will continue on its path and be faced with the point of the opposite direction.
