Temp of black hole
Web† primordial black hole (hypothetical): e.g. Rs(1015 gm)» 10¡13 cm. (Hawking temperature » 10 MeV; would flnish evaporating today if born in early universe.) Since M grows like r 3 at flxed density, one can have a black hole at any density. WebAnswer (1 of 9): Black holes are very cold. They are cold because they absorb everything including all heat. Naively you'd expect that a black hole would be at absolute zero. This …
