Does the universe have a shape?

The universe doesn't have a defined shape for several reasons, however, it does have a general shape it resembles. The universe is round for the most part but not all angles are equally full so to say. There is a so called "center" and this is where the Big Bang occurred. After this event, all of the matter in the known universe was spread in a mostly even fashion at a particular speed outwards. This speed is constantly slowing however as gravity is causing the universe towards a possible "Big Crunch," where all matter will be brought back into an infinitely small point.

This means that the universe is mostly round, but has no true shape.

Based on a number of observations, including the cosmic microwave background radiation, the dominant cosmological model currently holds that the universe is flat. But as our understanding of the universe expands, this understanding may change.
