Black holes radiates like coals
WebA black hole is formed when a star of more than 5 solar masses runs out of energy fuel, and the outer layers of gas is thrown out in a supernova explosion. The core of the star collapses to a super dense neutron star or a Black Hole where even the atomic nuclei are squeezed together. The energy density goes to infinity. WebThis process by which black holes lose mass is very slow (at least for massive black holes made from stars), so the time it would take for a typical black hole to eventually disappear is very long. (For a black hole of a mass equal to the mass of the Sun, the entire process would take about 10**66 years, or 1 with 66 zeros after it.)

More precisely, he showed that for a predictable black hole satisfying R ab k a k b ≥ 0 for all null k a, the surface area of the future event horizon never decreases with time. A ‘predictable’ black hole is one for which the cosmic …
