Ok, I was bored during math class and came up with it. There's probably lots of things wrong with this, but that's ok, it kept me entertained for a while.

Loops: Most, if not all of my theories are based on the idea that most things in nature are loops. They start somewhere and eventually end up in the same place. Take the Earth for example. You start in... uhhh... where do you wanna start? I've always wanted to go to Alaska, so let's say you start there. Alright, you start in Alaska and walk/swim in a straight line. Eventually, no matter which direction you were facing when you started moving, you will end up in exactly the same place as you started. Making the Earth a loop. Now think of atoms. The electrons circle, or loop, around the neutron. Eventually they'll end up back where they started. Alright, those are pretty simple, now I'll get into how energy is a loop. Energy is made of waves. Take light as an example. It travels in waves. Waves are a kind of loop. They aren't whole loops, but they're loops in at least one dimension. Waves are continually going up and down, hills and valleys. These repeat themselves, in a loop. It goes up to one point, comes down to one point, goes up to the same point as before, down to the same point... Yeah, so basically, it's at least partially a loop. It is also thought by some that protons, neutrons, and electrons are made of energy, making them loops in themselves.

Space: Like I said before, most of my theories are based on the idea that most things are loops. And this theory is no exception. I believe that space is a loop. You go into space and travel in a straight line and eventually you'll get back to where you started, although it would take a LONG * 10^(big number) time to do it, since space is.... Ugh, what's that word I'm looking for.... BIG. Okay, so this theory is based on the idea that the universe is a loop. Ready? Oh well, I really couldn't care less if you are or not. First let's think of other loops that we have. Circles are the simplest loops I can think of right now, so lets start with that. A circle is two dimensional. If you were living on a circle then it would appear to you as a straight line. You would walk straight down that line and eventually end up right where you started. But the things with circles is that you can only travel on one dimension, east and west. The next step in loops would be the sphere. Sphere's are three dimensions, and for practical purposes, the Earth is a sphere. To us the Earth simply looks like a bunch of flatness. You walk straight on it and you don't realize you're actually walking on a curve, but you are. And because of this, whereever you start from, you'll end up back there later. On spheres you can travel in two dimensions, east/west, and north/south. This is what I based my theory on the shape of the universe around. Since a circle, which is two dimensional, allows travel in one dimension, and since a sphere, which is three dimensional, allows travel in two dimensions, space could be neither of those shapes. It couldn't be because in space we can travel in *three* dimensions. East/west, north/south, and up/down. So, I figure since a circle is two dimensions and you can travel in one dimension, and since spheres are three dimensional and you can travel in 2 dimensions, the universe must be a four dimensional sphere. This way, whichever direction we go in three dimensions, we eventually end up where we started. The universe is a loop. This theory also accounts for the expanding universe idea. If two dots are on a balloon, and you blow it up, the dots get further apart then they were before. This works the same way with the universe. All things are on the "surface" of the four dimensional sphere. The four dimensional sphere is expanding, and this is causing all objects in the universe to be spreading further and further apart.
