Hawking radiation, sometimes also called Bekenstein-Hawking radiation, is a theoretical prediction from British physicist Stephen … 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… WebOct 28, 2024 · There are no virtual particles (or antiparticles) with negative energy falling into the black hole; in fact there aren’t any real, massive particles being emitted as part of Hawking radiation... kugb train with the champions
