Normally, a black hole is considered to draw all matter and energy in the surrounding region into it, as a result of the intense gravitational fields; however, in 1972 the Israeli physicist Jacob Bekenstein suggested that black holes should have a well-defined entropy, and initiated the development of black hole thermodynamics, including the …
