The universe is a closed system. Relativity proves this: There is nothing outside of the universe. It wraps around into itself. You go far enough, you get back to where you started. There isn't even nothing outside of the universe. There is no. That's it. It's crazy.:[

Enjoy it? Although you can't prove that the universe wraps around itself. The [i]space[/i] could be infinite, but not the [i]matter[/i].
