Re:2 Dimensional Sphere? (Score 1)

the "edge" of the 3-ball is the outside layer(which is a 2-sphere). in a 3-sphere, you have a 3-ball where every point on this outside layer is the same as every other point. you can't picture it in 3-d, but a 3-sphere is kind of like a 3-ball that you can fly around inside and when you get to the edge you're at ALL the edge at the same time
