Cosmologists study the shape of the universe. They currently believe that the universe has a Euclidean geometry, meaning that it is spatially flat on large scales. Nevertheless, there is still debate among scientists regarding the overall shape of the universe, with some theories suggesting that it could be infinite or finite, with possibilities such as spherical, hyperbolic, or flat geometries.
