How humans know about the existence of black holes

Black holes are formed due to the aging of stars and the collapse of matter to the interior, black holes have strong suction, even light can't run out, black holes will not **, black holes can actually be understood as a compressed star, the internal matter is extremely dense, if the earth is compressed like a ping pong ball.

size, then the earth also becomes a black hole, the black hole will not **, only some unstable stars will ** and become supernovae.

Since human vision is produced by receiving light, and black holes cannot emit light, humans cannot observe black holes, and only when black holes absorb some stars that can emit light, can we infer its existence through the anomalies in the movement of luminous matter.

There is an accretion disk on the outer layer of the black hole's edge, and when massive objects fall into the black hole at high speed, they rub against the material inside the accretion disk, producing powerful X-rays. Because it is created outside the black hole, it can escape the constraints of gravity and be received by civilization. By capturing the powerful X-ray sources in the universe, the location of a black hole can be discovered.

Pure conjecture and speculation, human beings cannot prove it.

Black holes are not seen, they can be deduced through calculations and some special phenomena, and there will be large suction forces and special fluctuations in the vicinity of the black hole, through which the existence of black holes can be judged. Humans discovered the existence of black holes because they discovered that the magnetic field around them fluctuated differently.

Although black holes are difficult to observe, scientists still locate many black holes in the universe, these black holes do not rely on visual observation, but through gravitational calculations and special phenomena deduced - the huge gravitational pull of black holes will produce obvious gravitational waves, and will also form special gravitational lenses, through special phenomena to judge the possibility of the existence of black holes, and then scientists can judge whether black holes exist through the orbits of surrounding celestial bodies.

Black holes cannot be seen, mainly because humans have invented detectors that can hear the sounds inside the black hole, and satellites can refract the entire outline of the black hole.

A black hole is a five-dimensional space. In fact, the universe is essentially a multi-dimensional space-time world, but the current space on our earth is a relatively simple three-dimensional space. The black hole is in a five-dimensional space, which can be understood as a distortion of the four-dimensional space along the fifth dimension, and is pierced along the fifth dimension in the distortion, that is, a wormhole in the five-dimensional space of the four-dimensional space.

Nature of Black Holes:No matter what kind of material forms a black hole or what shape it is, black holes have no complex properties. As soon as something falls into a black hole, the area increases; If two black holes are combined into one, then the area of the new black hole formed by the merger will be equal to or greater than the sum of the original two black holes, that is, the area of the black hole will never decrease, which is called the black hole area does not decrease theorem.

A black hole is a kind of celestial body with infinite density and infinitely small volume in the universe in modern general relativity, and all physical theorems will fail when encountering a black hole.

Black holes are created by the gravitational collapse of a massive enough star after it runs out of fuel for a nuclear fusion reaction and dies. The mass of a black hole is so great that the gravitational field it produces is so strong that it is impossible for any matter or radiation to escape within one of the event horizons (critical points) of the black hole, not even the fastest propagating light (electromagnetic waves) currently known. 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 black holes can be obtained by using the "edge information" of ultraviolet and X-ray rays emitted by high heat before the object is inhaled. The existence of black holes can also be inferred by indirect observation of the orbit of stars or interstellar clouds.

Scientists' latest theories suggest that when a black hole dies, it may become a "white hole", which, instead of swallowing up all the matter in its vicinity, ejects all the matter captured by the previous black hole.

No one has ever entered a black hole, I just hope that there are no black holes and white holes in the world, and there are wormholes.

Don't talk nonsense about what you don't know, understand.

It's very simple and not so annoying.

The full name of a black hole is a low-light-speed black hole or a zero-light-speed black hole, as the name suggests, it will reduce the speed of light, the speed of light cannot be surpassed, the speed of light is zero, and nothing can come out of it.

At present, no black holes have been encountered, and black holes are just a region with a low speed of light, and they cannot enter or exit. Entering a black hole can live, nothing more than a return to the pastoral era.

No human has ever entered a black hole!

Humans cannot observe any information inside black holes. From the perspective of human beings, human beings can only get infinitely close to the surface of the black hole and cannot reach the black hole, and the information in the black hole cannot be transmitted, so human beings cannot get any information in the black hole.
