Let’s try another way to think about this.
A black hole of about 5 solar masses would have a temperature of about 12×10-9 Kelvin. The temperature of radiation emitted by a static black hole (without an accretion disc) is from pair production. The present calculation shows that the above feature could also be found even in the SAdS black hole. This is analogous to the zeroth law of thermodynamics, that the temperature T is constant for a system in thermal equilibrium. In effect the new formula counts the holes of a black hole and the spacetime that surrounds it (yes, even black holes have holes in them). Naively you'd expect that a black hole would be at absolute zero.
Scientists have now taken the temperature of the haze around a lab-made …
One of the virtual particles falls into the black hole, separating the pair. The temperature of space is about 2.7K which is quite a lot bigger. black hole is constant over its event horizon [2, 1]. The symbols used are: (black hole mass), (dimensionless spin parameter), (gravitational constant), (speed of light), (angular momentum), (speed of sound), (proton mass), (Thomson scattering cross section), (radiative efficiency), (reduced Planck’s constant), (Boltzmann’s …
The Hawking radiation is in the regime of linear dispersion, in analogy with a real black hole. This is analogous to the zeroth law of thermodynamics, that the temperature T is constant for a system in thermal equilibrium. For the large black hole, the metric A black hole has a temperature. The first law of black hole mechanics expresses the conservation of energy by relating the change in the black hole mass M to the changes in its area A, angular Another way of looking at it would be that the classical black hole has a temperature of absolute zero. The existence of black holes has presented physicists with a conundrum, albeit an alluring one to attempt to resolve. The Hawking radiation is in the regime of linear dispersion, in analogy with a real black hole. It probably emits a faint haze of particles.
Another way of looking at it would be that the classical black hole has a temperature of absolute zero. We measure the correlation spectrum of the Hawking radiation emitted by an analogue black hole and find it to be thermal at the Hawking temperature implied by the analogue surface gravity.
... and his colleagues have come up with their new formula to quickly and precisely calculate the Hawking radiation temperature from any kind of black hole. Physicists created a sonic black hole in the lab and then took its temperature — and the measurement seems to confirm a prediction made by Stephen Hawking.
Think of it this way. A black hole (illustrated) isn’t completely black. Black holes are very cold. The black hole loses mass when a virtual (negative-energy) particle-antiparticle pair forms exactly on the event horizon. The first law of black hole mechanics expresses the conservation of energy by relating the change in the black hole mass M to the changes in its area A, angular black hole is constant over its event horizon [2, 1].
Scientists have measured the temperatures of ultrafast winds streaming from black holes for the first time, revealing spikes and dips that take place in the span of just hours. This means you could take some hot mass and collapse it into a black hole… BLACK HOLE ENTROPY The second law of classical thermodynamics requires that black holes have entropy. The temperature of the black hole is inversely proportional to the mass of the black hole and the size of the event horizon.

So the temperature of space would be providing loads of energy to the black hole via the
