  • A black hole may not emit heat, but the accretion disk surrounding it certainly does. The gravity and spin causes clouds of gasses to rotate around the black hole at staggering speeds; the friction and other forces can heat the gasses to tens of thousands of degrees. Supermassive black holes can also expel these gasses at relativistic speeds along their axis of rotation. Black holes can give off plenty of energy without letting anything escape the event horizon.
