To prove the existence of any other dimensions we would have to use high powered experiments like the Large Hadron Collider or theoretical physics. For instance, string theory, which suggests that the most elementary particles in the universe are tiny vibrating strings. This theory proposes that the universe could be made up of as many as 11 dimensions. Weird, right? Now for theoretical physicists this opened up a world of possibilities. For instance, back in 2002, physicists theorized that if the universe did have 5 dimensions, -- a crazy kind of 5D black hole, called a black ring, could exist. However, it wasn't until recently that they were able to model what these would look like. It was scientists from UNiversity of Cambridge and Queen Mary University of London who used the COSMOS supercomputer to run a simulation on black rings. The results published in the journal Physical Review Letters found that a black ring is highly unstable. And that its structure can pull apart, kind of like silly putty. The researchers found that a black ring could in fact, be stretched out so thinly, that it could produce smaller mini-black holes that were pinched off from the main ring. Now as the ring breaks apart it becomes what's called a “naked singularity”, which is where things gets weird. Now a singularity is located right in the center of a black hole and it's where the gravitational field is most dense. But since nothing, not even light can escape a black hole, we can't see these singularities. But a black ring in a 5 dimensional universe with a naked singularity would be very different. Naked singularities are so named, because they are no longer hidden within the boundaries of a black hole or the event horizon. Remember, these singularities are formed as a black ring is breaking apart to form new black holes. Basically, what this all means is that we could potentially see them!* And unlike a 4D singularity, you might even be able to GO INSIDE OF A NAKED SINGULARITY AND COME OUT ALIVE. Simply put, all this turns Einstein's theory of relativity on it's head. That's because all of Einstein's equations to predict the future of our universe and how it works are all based on the idea that it exists in 4 dimensions. If we can prove that black rings exist it means that his theory, isn't wrong but could be incomplete. This means that researchers would have to find a whole new theory to explain the universe. But like I said, this is only a computer model, for now it's like scientists are just having fun seeing how far they can stretch physics on a computer.
