These objects' thermodynamic processes inspired the holographic principle, and the  ergosphere surrounds a rotating one of these objects.
These objects' thermodynamic processes inspired the holographic principle, and the  ergosphere surrounds a rotating one of these objects. They can evaporate due to virtual particles  in Hawking Radiation. Mass, angular momentum, and electric charge can completely describe a  stationary one of these objects. The entropy of these objects is proportional to the area of their  surface, which is called the event horizon. For 10 points, identify these celestial objects with a  singularity at their centers and from which not even light can escape.
