Abstract
The black hole is a region in space in which nothing can escape its pull. The two important parts of the anatomy of a stable black hole are the event horizon and gravitational singularity. The main discussion is regarding the temperature of a black hole. Absolute zero is a state which enthalpy and entropy is zero. The temperature of a black hole approaches the gravitational singularity in which space-time possibly ceases and entropy is zero producing absolute zero or possible sub- absolute zero.
Highlights
Absolute zero is the lower limit of the thermodynamic temperature scale, a state of which the enthalpy and entropy of cooled ideal gas reaches minimum value, taken as 0
Hc3 8GM kg where h is the Dirac constant, c is the speed of light, k8 is the Boltzmann constant, G is the gravitational constant, M is the mass of the black hole and Mʘ is the mass of the sun. This has important consequences; the bigger the black hole the colder it is, and the slower it loses mass. If this is the case, the temperature approaches absolute zero as a mass from the event horizon gets closer to the gravitational singularity
Absolute zero occurs past the event horizon and toward the gravitational singularity of the black hole
Summary
Absolute zero is the lower limit of the thermodynamic temperature scale, a state of which the enthalpy and entropy of cooled ideal gas reaches minimum value, taken as 0. Quantum field theory in curved space time predicts that event horizons emit Hawking radiation with the same spectrum as a black body of a temperature inversely proportional to its mass. For a non-rotating black hole, this region takes the shape of a single point and for a rotating black hole, it is a smear that lies in the plane of rotation [9] In both cases, the singular region has zero volume. This has important consequences; the bigger the black hole the colder it is, and the slower it loses mass If this is the case, the temperature approaches absolute zero as a mass from the event horizon gets closer to the gravitational singularity. The possibility of sub-absolute zero occurs inside the black hole at the site of zero entropy, the gravitational singularity. Absolute zero occurs past the event horizon and toward the gravitational singularity of the black hole. Temperature of a black hole is included in one discussion of the properties
