Most galaxies in the universe have at least one thing in common: supermassive black holes tend to sit in their centers, silently gorging on interstellar gas and dust and obliterating anything that comes within range of their event horizon. But scientists know very little about the origin of these behemoths or how they got to be so supermassive.

Stephen Hawking has a big announcement.No, it's not that aliens exist or that humans won't survive another 1,000 years on Earth.

With no event horizons, there are no black holes, according to Hawking.
