Black holes are not create energy it transforms energy into another form.

The black hole behaves like all other spinning particles. 

When we think about the energy that black holes send we must remember the golden rule of energy. A black hole doesn't create energy from emptiness. It just transforms energy or wave movement into another form. Every fundamental interaction has particle and wave movement forms. Those fundamental forces' wavelength depends on the diameter of the particle that sends radiation. 

When as an example, neutron stars send radiation that radiation forms when neutrons on neutron stars' shells push quantum fields outside it. That radiation's wavelength is the same as neutrons. That means neutron stars can also send neutron radiation. 

The reason for that is that neutrons form small balls at the neutron star's shell. And there is a possibility that quark stars are invisible because the quarks are far smaller particles than neutrons. So if gluon stars exist their wavelength would be shorter than the hypothetical quark stars. 

And then the reason for gravitational radiation from a black hole's singularity is that there is roughness on the singularity whose size is the same as the hypothetical graviton particle that should be a gravitational transportation particle. 

Strong interaction has a short wavelength because it's a transmitter particle gluon is very small. So we can conclude that graviton should be smaller than gluon.  And we could say that a black hole transforms some fundamental interactions' wavelengths into other forms by adjusting those forces' wavelengths. 

Another way to adjust the wavelength is to use a spinning disk or ball. It's possible. That there is disk shape structure of superstrings in the singularity. But spinning objects always behave in the same way. And if you want, you can replace the word disk by using the word "ball". 

The spinning disk transports energy from inside to outside. And when energy travels out from the disk, replacing energy falls inside the disk. That energy will get between those atoms it breaks the disk. 

Another thing is that the roughness on the edge of the plate causes a situation. That energy transportation out from the disk is not fully symmetrical. Also, those anomalies in circular form cause a situation, where energy jumps out from the plate into every direction and forms a standing wave. That standing wave pushes energy back into the black hole and it pushes or turns superstrings out from the structure. That thing causes vaporization. 

The material disk could be the impact area where the energy that travels out from the black hole impact with particles that fall through the event horizon. 

The black hole's singularity is not slight either. There are small waves in superstrings that form the singularity. And those waves make a situation where there is a small quantum vacuum near the singularity. The vacuum's deepest point is the point where the ball's rotating speed is the fastest. And in the case of the singularity that is in its equator line if we think that the rotation axle is the point of the poles of a black hole. 

Is the key to a black hole's extreme gravitation that the singularity is the slightest object in the universe? The form of singularity could describe as an extremely tight superstring entirety. When a black hole or its singularity spins. 

That thing sends wave movement outside. That means there could be two layers of wave movement around the singularity. The outer wave movement layer takes energy or wave movement to the black hole's or singularity's poles. And the inner layer brings wave movement in the black hole from its poles. 

Then that wave movement that falls inside the black hole from its poles continues its travel from the singularity's equator. And that forms the transition disk around the black hole. The idea is that the transition disk or material disk is the impact area where energy or gravitational waves impact with material and wave movement that comes outside.
