Input (English): These objects can have an internal boundary named for Cauchy, and they can also be extremal according to the Reissner-Nordstrom metric. If the charge to mass ratio is any higher, they can violate the Cosmic Censorship Hypothesis. Their entropy was conjectured to be inversely proportional to the Planck length squared by Bekenstein, who sometimes names a process in which spontaneous pair production results in them giving off energy, known as Hawking radiation. For 10 points, name these objects, which occur above the Chandraseker limit, consisting of an event horizon surrounding a singularity, and which are so massive that no light can escape.
Output (English): Science
