The Shape Of The Universe Explained

I’ve posted other things about the shape of the universe, but nothing that is quite as clear as this video.  The gist of the video is that we are three dimensional beings in a higher dimensional universe and you can have a universe that looks flat and finite but still travel in one direction only to end up back where you started.  This is similar to walking around a sphere only supesized!  I am in awe of people that can take such a difficult concept to wrap your mind around and make it easy to understand and clever at the same time.  This is part one of a promised three and covers the idea of a flat universe, which you may recall is one of three recognized models for the shape of the universe.  The others being spherical and hyperbolic.  Those will be covered in the next videos to come.  Watch:
