Must rotate at a very high speed.

The origin of the galactic galaxy in one cosmic galaxy: the initial heavy particles and heavy matter move in one direction, due to the aggregation and sedimentation of heavy matter into a super-aggregate, the internal ultra-high temperature, the reaction eruption produces light matter and the original light matter spreads outward. The heavy matter of the superpolymer gradually turns into light atoms and escapes outward.
The internal collapse eventually turns into a high-speed rotating black hole, and under the action of gravitational waves, the matter body rotates and rubs, and acts into a planet with different specific gravity. The centripetal force of the cantilever rotates into the first billions of small galaxies. It is the work of the solar system.

The angular momentum of a black hole comes from the angular momentum of the original collapsed star. Generally, no star happens to be rotating, so newly formed black holes are generally rotating.
However, due to the special properties of the rotating black hole, also known as the Kerr black hole, it will drive the space-time around him to rotate with him, which makes the matter that flies against the black hole will inevitably fall into the black hole, and the matter that flies along the black hole may fly away from the black hole, and the final velocity is greater than the initial velocity, taking away the energy. It is foreseeable that sooner or later, the black hole will lose all its angular momentum and become a black hole that does not rotate.
And this loss is due to classical motion rather than quantum effects, which should be much faster than the evaporation of a black hole. So, one day the black hole will stop. <>

Black holes rotate at nearly half the speed of light. The scientific community generally thinks that the rotation speed of a giant black hole is about 45% of the speed of light, but a team led by Akira Kato of the Japan Aerospace Exploration Agency found that the rotation speed of a black hole is 22% of the speed of light, which is only half the speed previously estimated, and that the rotation speed of a giant closed black hole is no different from that of a low-mass black hole.
When a stellar-mass black hole grows into a giant black hole, it absorbs massive gas and angular motion through a rotating falling disk, so the rotation speed of the giant black hole should be greater. However, the results of this study show that the rotation speed of a giant black hole is not much different from that of a smaller stellar mass black hole.
The physical spike nature of black holes.
Black holes cannot be directly observed, but their existence and mass can be known indirectly, and their effects on other things can be observed. Information about the existence of a black hole can be obtained by emitting "edge messages" such as X-rays and guessing hands by emitting X-rays and guessing hands due to friction caused by the acceleration caused by the gravitational pull of the black hole before the object is sucked in. The existence of a black hole can also be inferred by indirectly observing the orbit of a star or interstellar cloud air mass, and its position and mass can also be obtained.

The black hole belongs to a completely isolated star, a strange spirit body, we can not directly observe him, to be precise, all matter in the universe is basically around the black hole, except for the rotation around some stars, is around the black hole, into the black hole gravitational field, all the matter will be sucked into the inside, just like the big fish eat the small fish, whoever has a strong gravitational pull, who is the boss!
Galaxy. As a whole, participate in this galaxy cluster.
and other motions. Astronomers believe that the Milky Way and the Milky Way are moving at a speed of 600 kilometers per second relative to the nearby observed galaxies, with most estimates between 130 and 1,000 kilometers per second. If the Milky Way were indeed moving at 600 kilometers per second, we would be moving 51.84 million kilometers per day, or 18.9 billion kilometers per year.
compared to the solar system.
Within, the distance traveled per year is the Earth with Pluto.
times the distance at the closest approach. The direction of the Milky Way's movement in space is towards the constellation Hydra.
And calmly. The universe is constantly expanding.
According to scientists, the most distant galaxies are moving outward at a rate of several kilometers per second, but the expansion rate of the universe is decreasing.

A black hole, black, indicates that it does not emit or reflect any light electromagnetic waves to the outside world. The cave is anything that once it enters its borders, it will not want to slip out again.
-
Black holes were first calculated by German mathematician Carl Schwarzschild, in the black hole around anything whether it is signal, light or matter can not escape, space-time here has become a bottomless pit, such a place that cannot be seen, touched or detected is called a black hole.
-
The driving force that supports the high-speed rotation of a black hole is gravity, because a black hole is originally similar to a planet, but its density is larger than that of ordinary planets, so generally planets close to it will be attracted by gravity.
-
It is powered by the gravitational pull of its very small but infinitely massive singularity on other objects, and this huge gravitational pull causes it to rotate at high speeds.
-
It should be the gravitational force inside the black hole, the black hole has a strong magnetic field, maybe this is the power of the **.

A rotating black hole, also known as a Kerr black hole, has two event horizons and two infinite redshift planes, and these four planes do not coincide. The event horizon is the boundary of a black hole, the boundary from which no matter (within the classical physical realm) can escape. An infinite redshift is an infinite redshift of light on this surface, i.e., a gravitational redshift occurs after the light is emitted from a boundary, and the frequency of the redshift is zero.
This boundary is the infinite redshift surface. It was not mentioned earlier because the event horizon and the infinite redshift plane of Schwarzschild black holes and charged black holes coincide, but the Kerr black hole does not coincide, and the two infinite redshift planes are inside the inner horizon and outside the outer horizon respectively, and the space enclosed by them and the event horizon is called the inner and outer energy layers respectively. Since the event horizon is the boundary of the black hole, the outer energy layer does not belong to the Kerr black hole and can only be counted as an accessory part of the black hole.
They are much like an egg, with a Kerr black hole being the yolk and the outer energy layer being a circle of egg whites surrounded by the outside. Under certain conditions, the matter in the outer energy layer may penetrate the infinite redshift plane into the outer world. Penros proved that under certain conditions, particles with lower energy may obtain energy from the energy layer after penetrating the energy layer, and have higher energy when passing out, which is the Penros process.
Through repeated operations through this process, the energy of the black hole can be extracted, causing the thinning of the energy layer, which is the rotational kinetic energy of the black hole. As the energy layer thins, the kinetic energy of the black hole decreases, and when the energy layer disappears, the Kerr black hole degenerates into a non-rotating Schwarzschild black hole, so it can no longer continue to extract energy in this way. The central singular zone in a Kerr black hole is not a point, but an odd ring, a circle of pecularities.

Black holes can be divided into non-rotating black holes and rotating black holes.
A non-rotating black hole, also known as a Schwarzschild black hole, is a non-rotating and uncharged black hole.
A rotating black hole, also known as a kerr black hole, is a rotating and chargeable black hole.
But in reality, a black hole can ionize nearby matter to neutralize its charge, so a Kerr black hole is actually chargeless.
Yes, there are countless universes in the universe, there are three-dimensional universes, four-dimensional universes, and material universes. At least 200 planets in our three-dimensional material universe have life. When aliens from other universes come to our universe, they will turn into invisible and intangible, electrographic ions before entering the black hole, and when they pass through the black hole, they will turn back into the prototype. >>>More
Of course, there is a singularity in a black hole. It is precisely because of the influence of the Schwarzschild singularity that the black hole has a huge gravitational pull that no other celestial body has so far been able to match. As we all know, black holes are arguably the most mysterious and threatening celestial objects discovered in the observable universe so far. >>>More

The cool of summer sometimes makes their work less efficient, if there is an electric fan or air conditioner on the side to cool down the environment we are in, it is also very good, many people have found a fan that rotates at high speed, why can you see clearly at each blade of the light at night? That's because our eyes have to see through the reflected light of the object into the eye, and the light produced by the electric light is not continuous, so we see the leaves very clearly in the light at night. Let's find out why. >>>More
