Where does the black hole lead? Where exactly are the black holes?

Eh, this question has not been conclusive, but at this stage, most people agree that a black hole is not a hole, just a celestial body with a mass almost concentrated to one point, because the gravitational force is very large, and the surrounding light is sucked in, so it looks black, like a hole, but because the gravitational force is too large, nothing can only enter and exit, so there is no way to guarantee whether it can really lead to **. According to the principle of the universe, there should be other universes.

The gravitational force is generated ......It's complicated to say, I've heard of Newton's law of gravitation. That is to say, everything has a gravitational pull, and it is just different in size. And the more massive the object, the greater the gravitational pull.

As for the celestial bodies that are sucked in, due to the gravitational pull, they are also compressed (colloquially flattened) and become part of the black hole. To understand black holes, we must first make it clear that "black holes are not holes".

The black hole is consumed by the energy of the superred giant, so the inner core collapses into a black hole, everyone knows that the gravitational pull of the sun is large, and it captures 8 planets, but it is only a red giant, and the black hole is formed by the collapse of the superred giant, so the gravitational force is greater, and when it absorbs other cosmic matter, its gravitational pull is greater and greater, but it must be that it absorbs a large number of negatively charged particles and neutralizes with its own positively charged particles, that is, its mass will decrease, and the gravitational force will also decrease. So the gravitational pull of a black hole is not infinitely expanding, our sun is a red giant, and it is a white dwarf formed after its energy is consumed, and the gravitational pull of a white dwarf is also very large, dozens of times that of the sun, and its mass is also very large. In fact, with the current state of technology, people are not able to do it, because the gravitational pull of black holes is very large, which is well known, so as soon as humans get close to it, they will be torn into particles (invisible to the naked eye, the size of quarks) by its strong gravitational pullAt this point, people become particles.

Horror bar. Not even a drop of blood will come out and disappear directly. The celestial bodies that were sucked in were also broken up into particles like people If you're satisfied, don't forget to +point This is just my humble opinion, and I hope you can point out if there are any mistakes.

I can correct it too.

As we know about black holes, they are not portals to another universe, but evolved from very massive stars. It is possible that wormholes are portals to other universes, and if possible, we may be able to travel through time and space through wormholes.

Here's a brief introduction to black holes:

A particularly dense dark object predicted by general relativity. Massive stars collapse at the end of their evolution, and their matter is so dense that it has a closed boundary called the "event horizon", and the black hole hides a huge gravitational field that is so strong that any matter, including photons, can only enter and cannot escape. The lower limit of the mass of the nucleus of the formation of a black hole is about 3 times the mass of the sun, which, of course, is the mass of the last nucleus, not the mass of the star in the main sequence period.

In addition to this stellar black hole, there are other black holes - the so-called miniature black holes may have formed in the early universe, and the so-called supermassive black holes may exist in galaxies**.

The black hole cannot be seen directly, it is calculated based on its force on the surrounding celestial bodies, and the celestial bodies sucked in by the black hole are not gone, but the mass of the black hole is increased; Mass produces gravity, and the same goes for the Earth;

Black holes are contradictory, and many scientists no longer believe in the existence of black holes, so black holes are just an imaginary of the Hawkingist brain.

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 cause serious distortions of space-time due to their high quality, in fact, any object with mass can cause space-time distortions, this is a prediction made by the general theory of relativity, which was originally verified by a solar eclipse in World War II, but because the war test was not carried out, of course, the truth will always be proven. The distortion of space-time caused by the sun makes it possible for the light from behind, which would otherwise be completely obscured by the sun, to shine on the Earth.

When you say black holes, you're referring to.

Person: Get married as soon as possible.

Hole in the ground: You have your flashlight ready.

Celestial Bodies: You go to a brief history of time.

Black holes cannot be seen, and even their existence has not been successfully confirmed, so it can only be said that objects that are suspected of black holes, such as Sagittarius A.

Now it's invisible. The gravitational pull of a black hole can even absorb light, so we can't see ...

Writers have recently observed the existence of a huge black hole at the center of the Milky Way, which is estimated to be the second largest black hole in the Milky Way. The findings have been published in the latest issue of the journal Astronomy and Astrophysics.

Just three years ago, astronomers observed the Milky Way orbiting a supermassive black hole that is 26 million times more massive than the Sun. Now a smaller black hole with 1,300 times the mass of the Sun has been discovered, moving just 3 light-years away.

A team led by Genen Pierre Mérald, an astronomer from the Institute of Astrophysics in Paris, France, observed a very bright region at the core of the Milky Way called IRS13, which astronomers previously thought was a single star. At the Gemini Observatory at the summit of Mauna Kea on Hawaii's Big Island, astronomers used infrared observation to find that IRS13 is actually a constellation of seven stars, only light-years apart. Using data collected by the Hubble Telescope and the Chandra X-ray Observatory, they estimated from the motion of the seven stars that they must be orbiting around an intermassive black hole, called IRS13E, which orbits Sagittarius A* at a speed of about 280 kilometers per second.

"This is the first time that a mid-mass black hole has been discovered in our Milky Way," Maillard said. Scientists also found that IRS13 emits intense X-rays and has a long tail that masks the black hole.

Faint X-rays can be detected in many places throughout the Milky Way, suggesting that there may be many "pocket-sized" black holes close to Earth, and these small black holes are only 1 to 2 times the mass of the Sun, but this is only speculation and needs to be further confirmed.

According to Melald's analysis, these seven stars may be the remnants of a massive star group, which is likely to gradually lose its original mass due to the attraction of the supermassive Milky Way**. The results of this observation help to confirm the hypothesis that supermassive black holes exist at the centers of many galaxies and gradually increase their mass by absorbing the mass of other small black holes and stars in the galaxy.

This may also explain why so many massive stars are found in this region. When a gravitational star orbits A* Sagittarius, it prevents the formation of new stars from clouds of dust and gas. It is possible that these stars formed far away in the Milky Way and were then attracted to their current location by the huge mid-medium black hole.

Judging by their size and color, these 7 stars may be short-lived, or they may burn out sooner than we expected.

The creation of a black hole is similar to that of a neutron star: when a star is preparing to perish, the core of a star rapidly shrinks and collapses under the force of its own gravity. When all the matter in the core turns into neutrons, the contraction process immediately stops, and it is compressed into a dense star, which also compresses the space and time inside.

But in the case of black holes, the mass of the star's core is so large that the contraction process goes on endlessly, and even the repulsion between neutrons cannot be stopped. The neutrons themselves are crushed into powder by the attraction of the squeezing gravity itself, leaving behind a material of unimaginably high density. The gravitational pull due to the high quality is such that any object that comes close to it will be sucked into it.

I don't know, it's very, very far away from the Earth anyway.

The stars we see on a clear night don't really mean anything, they are just some luminous objects in the universe. However, there are some stars that do not emit light, but they have a much greater significance. Astronomers launch astronomical observers into the air to study invisible light in space.

In the X-ray universe** sent back, it can be seen that the stars that were previously thought to have "disappeared" still exist in the universe and emit intense cosmic rays, even stronger than stars such as the Sun. This also proves a bizarre assumption for a long time: invisible "black holes" really exist in the universe.

Most galaxies in the universe, including the Milky Way where we live, hide a supermassive black hole at its center. These black holes vary in size from 1 million solar masses to 10 billion solar masses.

Astronomers have inferred the existence of black holes by detecting the intense radiation emitted by the accretion disks around them. When matter falls under the gravitational pull of a strong black hole, it will form an accretion disk around it and spiral down, and in the process, the potential energy is rapidly released, heating the matter to extremely high temperatures, thus emitting intense radiation. Black holes devour surrounding matter by accretion, which may be how it grows.

Observations also show that active black holes that occur when the universe is only 1.2 billion years old are 10 times less massive than most massive black holes that appear later. But they grow very fast, so they are now much more massive than the latter. The oldest black holes, which are only 100 to 1,000 times more massive than the Sun, may have formed and evolved in connection with the earliest stars in the universe.

Astronomers have also noted that after the first 1.2 billion years, the growth of these observed black hole objects lasted only 120 million years.

A black hole is not a hole, on the contrary, a black hole is a huge mass of matter, it will suck in everything that passes through it, even the light, the black hole is just a name based on its appearance.

A black hole is not a hole, because it looks like a bottomless black hole that can swallow anything, so it is called a black hole.

A black hole is not actually a hole, scientists give it this name only because it does not have any light in it, like a deep cave. Strictly speaking, it is a cosmic phenomenon that is not the same as the cave we know.

Black holes have always been full of mystery, devouring everything around them, and not even light can escape. To this day, we still can't understand what happened to the matter swallowed by the black hole. What mysterious power is hidden inside a black hole?

At 21 o'clock on April 10, 2019, Beijing time, mankind's first black hole** was unveiled, which is a black hole located in the constellation Virgo 55 million light-years away from Earth, with a mass of about 6.5 billion times that of the Sun. The advent of this ** once again proves the correctness of Einstein's theory of relativity.

So the matter that was swallowed by the black hole went**? This is completely inconsistent with the law of conservation of energy. So Hawking proposed Hawking radiation, thinking that black holes would undergo evaporative radiation.

Every time it evaporates a little bit, it will evaporate and disappear after years and billions of years, so the black hole is not an isolated system, but participates in the energy cycle of the universe and participates in the entropy increase of the universe.

However, many people do not agree with this statement, and people agree that there is a rule inside a black hole that we cannot imagine or know. Einstein believed that matter can distort space, so it is highly likely that the other end of the black hole is another space, and the black hole is the entrance to the wormhole in the universe.

There is also a corollary based on the law of conservation of energy. Scientists believe that in addition to black holes, there should also be a kind of white hole, the opposite of black holes. The white hole is a jet source in the universe, it cannot absorb any matter and radiation from the external region, but it will release a huge amount of energy and has a super repulsive force, and the black hole and the white hole are very likely to complement each other.

One absorbs everything, the other sprays everything, thus achieving some kind of energy cycle.

So what exactly is inside a black hole? Due to the characteristics of black holes, no light can escape, and there is no reflection of light, making the black hole pitch black. So we can't observe what a black hole looks like.

As for the black hole we photographed, it is because due to the strong gravitational pull of the black hole, the light from behind the black hole will be bent to form a ring of light that surrounds the edge of the black hole's event horizon. Due to the Doppler effect of rotation, one side of this halo will appear brighter than the other.

In other words, the ** of the black hole we see is actually the black hole with the center black. The bright orange light on the outside is simply the effect of light around the black hole. So at the moment we can only guess that the black hole is an infinitely dense object, and you can think of it as an upgraded version of the neutron star.
