Supermassive black holes lurk in almost every large galaxy, including our own, but their origins are more elusive. Between them is what astronomers now believe to be a supermassive black hole (SMBH) in its infancy. Whatever the object is, it is accreting tons upon tons of material, and supermassive black holes are known for their voracious appetites. The “light seeds” theory claims that supermassive black holes are the product of black holes that form after massive stars go supernova, collapsing in on themselves in violent explosions. These black holes then merge into larger black holes.
