What is the shape of the universe? Judging by general relativity, the shape of the universe could be roughly spherical, and also roughly cylindrical. Another interesting thing is that the universe actually could be static and un-expanding or contracting. Imagine the universe like the earth, spherical. Now, imagine the galaxies as tectonic plates. As they go farther away, we cant see their light as well, but in turn, the universe does not need to expand.
