general relativity - Surface gravity and mass of a black hole

When particles escape, the black hole loses a small amount of its energy and therefore some of its mass (mass and energy are related by Einstein's equation E = mc ). Consequently, an evaporating black hole will have a finite lifespan. By dimensional analysis, the life span of a black hole can be shown to scale as the cube of its initial mass, and Hawking estimated that any black hole formed in the early universe with a mass of less than approximately 10 g would have evap… WebApr 11, 2024 · Now, if we choose the entropy of the black hole to be Eq. 1, we find the following expression for the temperature of the black hole: Equation 17: Temperature of the black hole with the choice of entropy S given by Eq. 1. For Q = J =0 this becomes: Equation 18: Temperature of the Hawking radiation. WebA black hole is a region of spacetime in which the attractive force of gravity is so strong that not even light escapes. As a result, black holes are not visible to the eye, although they can be detected from the behavior of light and matter nearby.
