“When galaxies collide, the chaos does not stop with stars and gas. At the center of each galaxy, Supermassive Black Holes (SMBHs) can fall into a tightening gravitational dance, spiraling together until they merge into one enormous remnant. In some cases, the final black hole may not remain where it formed. It can be “kicked” away from the galactic center at extraordinary speed.” (ScitechDaily, Astronomers Find a New Clue for Detecting Runaway Supermassive Black Holes)
Normally, black holes do not move. They move spacetime. But the asymmetry. in spacetime. Or in the gravitational waves. It can give a kick. To the black hole to move. If another side of the black hole. Or its environment has a lower energy level. That thing can make the black hole move. Another thing. That can put a black hole. Into the move. It is larger.
And a heavier object. The star has a mass. That is five times larger than the sun. Closes a black hole that is about 3-4 times heavier than the sun. The mass of that star is higher. But the black hole has a stronger. And a denser gravity field. So first, the star pulls a black hole into it. But then the black hole starts to pull matter from the star. The gravitational pothole around the black hole. It is deeper than around the star. Then matter starts to fall into the black hole.
Can recoil push a black hole to move? “Astronomers have searched for these 'recoiling' black holes for decades, but they are difficult to identify. A new paper available on arXiv, written by an international team, proposes a different way to look for them by studying the dust and gas that may stay bound to a black hole after it is launched from the center of its galaxy.” (ScitechDaily, Astronomers Find a New Clue for Detecting Runaway Supermassive Black Holes)
“The kick comes from a consequence of Einstein’s theory of general relativity. When two merging black holes have unequal masses or spins that point in different directions, the gravitational waves they release can carry more momentum one way than another. The merged black hole is then pushed in the opposite direction. In extreme cases, that recoil can accelerate the black hole to hundreds or even thousands of kilometers per second.” (ScitechDaily, Astronomers Find a New Clue for Detecting Runaway Supermassive Black Holes)
Asymmetry in the gravitational waves can kick black holes. That asymmetry mean. That is the lower or weaker. Gravitational waves. on the other side. And if the other side's gravitational waves are deeper or more powerful. The weaker gravitational waves. They fall. A black hole in the side. There. Gravitational waves are stronger. Stronger gravitational wave. It means that the energy ditches on that side are deeper. And those black holes fall into that side. Another interesting scenario. It is the disturbance in the black hole. Or its event horizon. There is a possibility that something causes asymmetry in the black hole’s event horizon. Or energy and matter flow in the black hole.
The position of the singularity. That is in the middle of the black hole. If that position changes. The event horizon. It moves to the new position. Another thing that can cause needed asymmetry. It is the gamma ray burst. That decreases entropy on the other side of the black hole. That can cause a stretch in the event horizon. When the position. Of the singularity changes. The other side of the event horizon “stretches”. That causes energy asymmetry in the event horizon.
The event horizon forms at the Schwarzschild radius. But another thing that affects the distance. It is the speed of light in that region. Things like entropy are also affecting that thing. So if the evaporation of the black hole. It is asymmetrical. That effect can also kick a black hole. To move.
When we think about the spiralic form of falling energy and matter. There is a possibility that a disturbance forms in that spiral. The idea is that. The asymmetry in matter and energy that falls into the black hole. It causes a minimal energy asymmetry near the singularity. If the singularity, or its position, moves. In the center of the black hole. That causes the event horizon to move to the new position.
The recoil effect means that. The black hole collisions. And other kinds of cases. They can form asymmetry in the black hole’s halo and material disks. When that asymmetry happens. That thing can put a black hole into motion. That asymmetry. It can form when another black hole stretches the material disk and halo around the larger black hole. When black holes collide. The first things that penetrate each other. They are black holes’ material disks and halos. That reaction. It can create very strong flashes of energy. When black holes collide. There is a model.
These black holes can pull quantum fields from between them. That means the quantum fields between those black holes turn very weak. Then other quantum fields. The sides of that channel can collapse into it. That can form the energy wave. That pushes those black holes to journey through the universe.
So, in the models. The change in energy symmetry in the extremely high energy region. around a black hole. It can cause a black hole movement. In some other models, the loss of entropy occurs at some point near the black hole. That can cause the recoil effect. The fast gamma-ray burst. It can form the channel. Through the universe. Or, a high-energy eruption near the black hole’s hemisphere. It can form the cosmic void. That void. It can pull a black hole into the trip.
