Microscopic examples of these are thought to exist at the Planck length, and the(*) Kerr Metric describes rotating types of these bodies.
Kruskal–Szekeres coordinates can be used to describe one type of these entities, and the Penrose process could hypothetically extract energy from them. Microscopic examples of these are thought to exist at the Planck length, and the(*) Kerr Metric describes rotating types of these bodies. Hawking radiation is emitted from them, and Schwarzschild determined the criteria for a neutron star to collapse into one of these objects. For 10 points, name these stellar objects, the super-massive variety of which is found in quasars and from which light cannot escape.
