Science fiction has often relied on the concept of black holes as a plot device, painting them as portals to other universes or as vehicles for time travel. But what happens when we take the fiction out of it? What’s really going on inside those terrifying faraway entities? In short, black holes are massive pits of gravity that bend space-time because of their incredibly dense centers, or singularities.. When a star dies, it collapses inward rapidly. As it collapses, the star explodes into a supernova—a catastrophic expulsion of its outer material. The dying star continues to collapse until it becomes a singularity—something consisting of zero volume and infinite density. It is this seemingly impossible contradiction that causes a black hole to form.
