There are stars with enough mass to collapse on themselves, forming what have been theorized as black holes. It is thought that within these black holes there is a point called "singularity" at which all physical laws may cease to exist. At this point the curvature of space-time becomes infinitely large, and modern science can no longer predict what will happen. Einstein's theory of relativity cannot determine what effect singularity will have on an object, forming an uncertainty in our universe. It is from this uncertain state that many theories have arisen surrounding singularity. It has been theorized that beyond singularity exist tunnels - shortcuts - to other ends of the universe. These "wormholes" could be a solution to interstellar travel, which currently is limited by relativity. However, many complications surround this possible theory. Most notable is the fact that the gravitational force of a black hole would crush any possible interstellar spacecraft, which is something that will have to be worked out. While this theory about singularity is questionable at best and will probably be left to science fiction, there is another theory about the center of a black hole that has been gaining more acceptance from respected physicists and astronomers, and describes a whole new view about our known universe.
