      There are a couple of different ideas about this, so far no one has been able to prove which one, if any, are right.

      Some people think that the universe is still expanding and getting bigger. (I want to know what its expanding into if it is supposed to be everything that exists). Some people think that it is a fixed size, and that when you get to the end you’ll have looped back round to where you started again. And other people think that its started shrinking. I don’t know if we’ll ever be able to prove which one is correct though as any changes that are happening are going really slowly.
