what is it outside the university

You have made a mistake. The word "university" should be "universe", right? Now, here is my answer:

Imagine a force that acts in a perfect way. A way that can allow a concept as enormous as infinite existance for matter and anti-matter. It is proven that our universe expands in all directions and resembles a spherical shape. What isn't proven, but what I believe, is that there are similar spherical shaped universes around our universe. All simulatenously expanding at the same rate. The reason is that it creates a chain effect which can cause an infinite expansion and deflation process, which is this:

Picture a bowl of marbles. The spheres arrange themselves in such a way that there is one point which holds SIGNIFICANT importance. I call it, the TRIPLE POINT. Each of the spheres in your marble bowl represents a single universe. Now in reality these marble spheres exist infinitly in numbers and are not limited to some sort of cosmic bowl.
