Cherenkov Radiation and Hawking Radiation

Abstract

While the speed of light has the constant value of 3 × 10 8 m/s in vacuum, its value diminishes in denser mediums. It is the purpose of this paper to show that as light enters regions of larger gravitational fields such as Neutron Stars and Black Holes light speed is also diminished. We consider the cases of Pulsars, Quasars, and Active Galactic Nuclei, to provide experimental proof that charged particles moving faster than the diminished speed of light in these high gravity regions would radiate energy due to Cherenkov Radiation that has been detected on earth as Radio Waves and X-Rays. We show that there is no experimental evidence for Hawking Radiation since the premise of its theoretical calculation is faulty.
