5D Black Holes Could Break Relativity

Ring-shaped, five-dimensional black holes could break Einstein's theory of general relativity, new research suggests. "Here we may have a first glimpse that four space-time dimensions is a very, very good choice, because otherwise, something pretty bad happens in the universe," said Ulrich Sperhake, a theoretical physicist at the University of Cambridge in England. From the beginning, Einstein's theory of general relativity, which describes how matter warps space-time, predicted its own demise.
