5D Black Hole Could "Break Relativity"
id = " General relativity is one of the greatest ideas in human history. Relativity and quantum mechanics are the cornerstones of modern physics, and telecommunications are used to computers and smartphones.
Unfortunately, relativity and quantum mechanics do not play well together. For that reason, theoretical physicists are searching for a theory that can unify them: the theory of everything. To do so, test the two theories to their limits, seeking their fundamental laws have been broken, and now new research has found a very interesting violation of general relativity. Researchers at the University of Cambridge and Queen Mary University looked an interesting scenario in general relativity and found that actually breaks. They used a supercomputer to model a black hole in a ring of five dimensions and found that the black hole became a naked singularity, which violate relativity. The results are published in
Physics Review Letters . Singularities such as black holes are objects of infinite density, and according to the laws of physics that is allowed to exist only if they are surrounded by an event horizon, a surface that separates them from the rest of the universe. Mathematically, you can not have a singularity "naked" (which exists outside of an event horizon) in our four-dimensional universe. This is aptly known as the cosmic censorship conjecture. "While singularities are hidden behind an event horizon, they do not cause problems and general relativity holds - the 'cosmic guess censorship' says this is always the case," study co-author Markus Kunesch, a doctoral student in the Department of Applied mathematics and theoretical Physics Cambridge (DAMTP) said in a statement
. "While conjecture cosmic censorship is valid, we can safely predict the future out of black holes. Because ultimately, what we are trying to do physics is to predict the future given the knowledge on the state of the universe now. "
conjecture cosmic censorship is believed to have for our universe, but the results of the question what is so special about a universe with three spatial dimensions and one time dimension. In addition, all possible theories as theories of quantum gravity and string require up to 11 dimensions so it is important to investigate the limits of our current theories. In this scenario, the fifth dimension is an extra dimension at random in space. "The better we get at the simulation of the theory of Einstein gravity in higher dimensions, the easier it will be for us to help with the advancement of new computational techniques - we are pushing the boundaries of what can do on a computer when it comes to Einstein's theory, "said co-author Tunyasuvunakool Saran. "But if cosmic censorship does not hold in higher dimensions, then maybe we need to look at what is special in a four-dimensional universe which means that it is held."
