Question

Is the universe circular?

Answer 1

The shape of the universe is the local and global geometry of the universe. The local features of the geometry of the universe are primarily described by its curvature, whereas the topology of the universe describes general global properties of its shape as of a continuous object.

Answer 2

Explanation:

All other cosmological data suggests the universe is flat, meaning it has no curvature, similar to a sheet of paper. These Planck measurements indicate that it could be “closed”, or spherical, which would mean that if you travelled far enough in one direction, you would end up back where you started.
