Direct solution of the problem of determining the temperature inside a black hole is not possible due to the uncertainty of the concept of the temperature of the event horizon.

thermodynamics formalism allows to calculate the temperature of the black hole indirectly by Hawking radiation whose spectrum Oddball strictly, and therefore depends only on the black hole temperature: T = ħc³ / 8πkGm, where m – a mass of the black hole.

Here, it is assumed that Oddball radiation is in thermal equilibrium with the black hole and the radiation emitter temperature may be attributed to the temperature of the black hole.

Substituting values into the formula of the fundamental constants, we obtain T ≈ 6⋅10⁻⁸ / M, where the temperature (T) measured in Kelvin and the mass of the black hole in units of solar masses (M = m / M⊙).

It can be seen that the temperature of the black hole is inversely proportional to the mass and weight in the hole 6 suns, the temperature is equal to T (M = 6) ≈ 10⁻⁸ K.

Note that this temperature is obtained on the basis of radiation emitted from a black hole’s event horizon, the Schwarzschild radius limited. For the case of M = 6, this corresponds to a radius of about 18 km.

The direct solution of the problem of determining the temperature inside a black hole is not possible due to the uncertainty of the concept of the temperature of the event horizon.

Good question! It depends on your speed. If you sit outside – the inside of a black hole is nothing (even space), and the temperature around it rolls over. The event horizon is so hot that its energy forms, black hole. Yes, it is possible and so to watch.

But if you fall into a black hole – with you nothing will happen, you do not even notice how to fly the horizon because for will be in another place. You, of course, it does not save from bursting into quarks singularity, but the horizon in your frame of reference will not be hotter than the surrounding space.

That is, the temperature, too, is relative, and the black hole – a perfect example of this amazing fact.
