Here, I got a good one that matches with String Theory and the Big Bang theory...
What if the universe WAS a singular point, the "0th" dimension if you will, but then, when the energy was pushed to its limits, then BAM, the universe broke the first dimension, then the second, then the third. This theory can help explain the odd shape of the universe and can help us think of string theory itself. This also works with several other universes.
BUT WAIT! THERE'S MORE!
I have an idea to discribe the universe and how it works, for the 0th dimension, it would simply be "A = 0", but for the 1st dimension, it would be "A = Infinity", showing it's potential, and the 2nd dimension? You'd think it would be "A = Infinity^2", but no, it's "A = Infinity^infinity", the 3rd? "A = Infinity^Infinity^Infinity", this goes on for several times over and over, showing simply the potential of the universes ability to expand infinately, several universes can be all sorts of dimensions.
