Think of the game Asteroids. If one goes all the way to the top of the screen, they end up at the bottom. If you go left, you end up on the left. That "universe" is infinite in a way. Now if you made the screen larger while every object remains the same size, you have an expanding universe that still has that still loops, making it a different kind of infinite. However, everything in that universe works in two dimensions:X and Y. But the universe is in three dimensions (in the shape of a bagel, to be precise) leading some people to think our 3-D perception of our universe is invalid. Some people think the universe could be in four or more dimensions, like some sort of Hyper-Bagel.

Sorry. This is hard to explain without pictures or some kind of example.

Also, happy New Year.

Does that mean that she soon can give herself an infinite hug?
