Equation of a black hole

WebFeb 3, 2024 · Black holes for which astronomical evidence exists have masses ranging from stellar-sized black holes of a few solar masses, up to supermassive black holes in the nuclei of galaxies, such as the \(6 \times 10^9\) solar mass black hole at the centre of the galaxy Messier 87. The Hawking radiation from such black holes is minuscule. WebIf this distance is greater than the radius of the sphere of mass itself, the event horizon is outside the sphere of mass, and the sphere cannot be seen: it is a black hole.
