cosmic topology

Cosmic topology explores the shape and structure of the universe on a large scale. Instead of thinking of the universe as flat like a sheet of paper, cosmic topology considers it more like a multi-dimensional space that might loop back on itself. This means that if you travel far enough in one direction, you could end up back where you started. Understanding cosmic topology helps scientists grasp how the universe is connected and how its geometry influences both the distribution of galaxies and the behavior of light traveling through it.
