expulsion of energy from the black hole.
This is a surprising question that you are asking me here. What do you want to know?
What 'expulsion' energy are you talking about?
That's why nothing goes into the black hole.
Are you serious?
Gravity draws us to it as much as energy plumps us up.
I am convinced that the supermassive black hole keeps the entire galaxy levitating by gravity and energy.
It is said that black holes swallow matter. There would then be as much matter to swallow as to push back to maintain the size of the galaxy.
On the other hand I just then published the gravitational oscillator with the model of the hole through the Earth
I've seen this concept discussed many times through the years.
What are your sources?
What do you mean by levitating? ...
... Is English your first language or are you using nonstandard meanings?

There is no need for a 'push back" from the black hole. For example, do you think there is something in the sun that is pushing the planets away?
Google this phrase: "tunnel through earth simple harmonic motion". You'll get hundreds of examples.
If there was no repulsive energy then we would fall into the black hole or on the sun. So yes there is energy that pushes us as much as gravity attracts us
There is no repulsive force necessary. You should look up orbital mechanics to help you see why.The the International space station doesn't fall to earth because it is moving in at a high rate of speed perpendicular to the force of gravity. The ISS is moving at about 7.7 km/s. If the speed of the ISS was stopped it would fall straight down to the earths surface. One way to visualize this is to think of the ISS (or ANYTHING orbiting) as a body that constantly falling towards the earth but its speed makes it miss the earth.There is no repulsive force involved.
*There is the avoidance by the kinetics which makes it possible not to fall into the true vacuum of the singularity. Indeed it happens at the level of the event horizon.
Isn't it just energy that makes the station move 7.7 km/s forward?
No, There is no energy being used to move the ISS. There are no engines running and no energy being input into the ISS to maintain the speed. Once the ISS had attained the velocity of 7.7 km/s it will continue to move at that speed until some force is applied to slow it down or speed it up. This is a little complicated because there is the force of gravity (as described by Newtonian physics) that changes the direction of the ISS but not it's speed. Look up Newtons first law of motion.
It is difficult to discuss these ideas because it is clear that you have not taken any physics courses and so you don't know some of these fundamental concepts. I recommend that you look at online courses on youtube for first year physics. Do not watch random youtubes or you could get immersed in pseudoscience. I do not know any courses in French, but if the video is from a University site you will get good information.Good luck.
There is a speed. Would you say that speed is without energy?
