My stupid theory of the universe...

[TheGuyWhoGoesMoo]

I think the universe is just a loop. If you keep going in the exact same direction, you'll end up in the same exact place. Kind of like going around Earth. However, I'm not sure how exactly how to explain how I think it works, but it all makes sense to me.

The "universe" is only 3-dimensional. There's a 4th dimension, so that's why no matter which way you go, you'll always be in the universe, and always end up in the same spot. It's like a 4-dimensional sphere, and we're only stuck on the outside. We can't get off it, no matter which of the 3-dimensions we travel.

Yeah I know I'm bad at explaining things, and still haven't taken any physics classes so... It's probably stupid. The ONLY reasion I came up with this about a year ago is so I'd stop thinking about what's out there, and have a reasonable answer.
