Also for the universe, physicists prefer the term 'finite but unbounded.'
Like you know how in some videogame minimaps, if you scroll to one edge you wind up on the other side and eventually back to where you began. Thats kinda how the universe would work if you went one linear direction at the speed of light (or very close). Emphasis on kinda.
