Introduction to black holes and white holes, the difference between white holes and black holes

The white hole is a strong gravitational source, its external gravitational properties are the same as the black hole, but the internal properties of the black hole are diametrically opposite, the black hole can swallow all the light and any matter in the adjacent cosmic region, but according to the white hole theory, the white hole can accretion the matter around it to the boundary to form a material layer, which can provide matter and energy to the outer region, but cannot absorb any matter and radiation in the external region, so the white hole is a special cosmic celestial body that only emits and does not absorb.

In terms of the timeline: its entire future is out there. Like Schwarzschild Sakura's solution, which predicted black holes, white holes are now just a mathematical solution based on the general theory of relativity.

Its outer gravitational properties are exactly the same as those of a black hole, while the inner properties are diametrically opposite, and it is a time-reversal version of a black hole. The singularity of a black hole can be thought of as a "future singularity" where matter will eventually fall and where time will terminate; The singularity of the white hole, on the other hand, can be thought of as a "past singularity", from which particles and particle time are born. You have to ask where it came from?

All I can say is: sorry, I don't know. Regardless of whether it is a white hole or a black hole, the current physical theory cannot describe the singularity.

What we do know is that these particles are born from the singularity of the white hole and then run out of the view, never looking back. Starting from the visual interface of the white hole, it is an area that "only goes out but does not enter". But physically, white holes cannot exist stably.

Its appearance will inevitably be accompanied by the birth of a black hole and its own disintegration, and it cannot directly constitute a so-called celestial body. Therefore, even if there is a white hole in the universe, it will be difficult for us to "catch" it. In addition to the possibility that it "does not exist", it may also be that the "window period" for observing it is too short.

A white hole is a state in which a black hole ages and collapses, and its space-time curvature is the opposite of that of a black hole, which expands infinitely. When it comes to the most terrifying celestial body in the universe, there is no doubt that it is a "black hole". How scary are black holes?

The smallest black hole in the known universe is still tens of thousands of times more massive than UY, the largest star in the constellation Shield today;

The volume is immeasurable. A black hole opens its bloody mouth and devours everything around it, including photons. However, do black holes have "natural enemies"? It is also said that this celestial body is called a white hole.

What is White Hole? This is a celestial body that modern scholars have hypothesized. Black holes, first developed in Einstein's "general theory of relativity" system, are regarded as a pit in time and space in dimensions, and have now been confirmed; Black holes, on the other hand, also have their own life cycles, which are about 10 billion years old.

When life reaches its end, the black hole collapses and becomes a "white hole". White holes are the opposite of black holes: they absorb all matter, while white holes eject all matter. Legend has it that inside the white hole, there is another mysterious existence: the wormhole.

It is said that when a black hole becomes a white hole, it will produce a "big **" from the inside out, and the volume of ** exceeds the limit of space-time bearing, which will open the "dimensional crack" and let people enter the wormhole. In the movie "Interstellar";

The male protagonist is in the black hole that is about to age, and reaches the four-dimensional space through the wormhole. In the four-dimensional space, time is presented in a linear manner, and human beings can see everything that happened in the past and the future from the perspective of a "bird's-eye view".

In this way, we can realize time travel. It can be said that the white hole, once confirmed, will be the largest discovery in the history of astronomical research. It will also open a new chapter for human beings to explore the universe and transform nature.

It is said that NASA researchers have recently made a new breakthrough!

A black hole is a special state of matter of a celestial body, representing a stage in the evolution of stars.

The initial stage of a star is a condensed cloud of air and dust, but it continues to shrink towards the center, becoming denser and warmer, and then becoming a bright and visible star. When the thermonuclear reaction inside the star produces an outward thermal pressure that just resists the inward gravitational pull, the star temporarily ceases to shrink and is in equilibrium. As time passes, the star's nuclear fuel burns less and less, the thermal pressure inside the star decreases, and the entire star shrinks sharply again, a process called "collapse".

Since dwarf stars and neutron stars are the result of star collapse. When there is nothing to stop the star from shrinking, the star dies, and a very small and extremely dense celestial body - a black hole appears.

Because the mass and gravitational attraction of this special celestial body is extremely large, as long as any object enters its gravitational range, it must be firmly attracted by it, and merge into a part of it, even the light will not escape its gravitational range, so people cannot see it at all, so the name "black hole" was born. Since black holes themselves do not emit light, they cannot be seen with any powerful telescope.

Both white holes and black holes are a type of celestial body predicted by the general theory of relativity. But the existence of white holes has not been confirmed by actual observations. A black hole has a boundary called the event horizon, and light or other matter can only enter the black hole through the event horizon and cannot escape from the black hole.

The white hole also has a similar boundary, but it is diametrically opposed to the black hole, the matter can only be launched from the white hole outward, but cannot enter the white hole from the outside, so the white hole is also called "the ejection source in the universe" by scientists.

A black hole is really what matter is du

It absorbs, including cosmic rays. zhi

According to the Hawking effect, the black hole DAO will also radiate some rays. The existence of white holes and the existence of black holes have not yet been determined.

But theoretically speaking, white holes and black holes are of opposite nature, black holes are constantly absorbing things; And the white hole is constantly releasing things!

Another: a celestial body that is theoretically prophesied. Its properties are the opposite of those of black holes.

The White Hole has a closed boundary. Unlike black holes, matter (including radiation) inside a white hole can be emitted through the boundary, while material outside the boundary cannot fall into the white hole. Therefore, the white hole is like a fountain, constantly spewing out matter (energy).

The White Hole Theory is mainly used in astronomy to explain some high-energy phenomena. There is no observational evidence of the existence of white holes. Some people believe that white holes do not exist.

Because the spatiotemporal properties of the outer part of a white hole are the same as those of a black hole, a white hole can accretion the material around it to the boundary to form a layer of matter. As long as there is enough matter, gravitational collapse occurs, leading to the formation of black holes. In addition, according to the current theory, massive stars may collapse to form black holes in the late stage of evolution. However, it is not known what processes lead to the formation of white holes.

If a white hole exists, it may have been left over from the time when the universe was large

A white hole is a strong gravitational source, and its external gravitational properties are the same as those of a black hole, and the white hole can accretion the material around it to the boundary to form a layer of matter. The white hole theory can mainly be used to explain some high-energy celestial phenomena. A white hole is a jet source in the universe that can provide matter and energy to the outer region, but cannot absorb any matter and radiation from the outer region, so a white hole is a special cosmic object that only emits and does not absorb, which is the opposite of a black hole.

A special celestial body predicted by general relativity with properties that are exactly the opposite of black holes. White holes are still only a theoretical model, but they have not been confirmed by observations. According to the white hole theory, a white hole is similar to a black hole in that it also has a closed boundary.

The matter that gathers in the white hole can only move outward through the boundary, not the opposite direction. Therefore, the material outside this celestial body cannot enter. According to the white hole theory, it has been suggested that the core of a quasar may be a white hole.

When the ultra-dense matter in the white hole is ejected outward, it will violently collide with the matter around it, thus releasing a huge amount of energy. It can be inferred that some phenomena such as X-rays, cosmic rays, radio bursts, and radio dual sources may be related to this effect of white holes. The force of the white hole is the force of repulsion that opposes the attraction of the black hole.

A white hole can accretion its surrounding material to the boundary to form a layer of matter. The White Hole Theory is mainly used to explain some high-energy celestial phenomena. At present, astronomers have not actually found a white hole, and it is still only a theoretical term.

The white hole is a very "scholarly" theoretical product obtained through the analogy of black holes, which is more of a mathematical model. Unlike black holes, white holes do not absorb any objects, instead, they continuously release matter, including elementary particles and fields. White holes, like black holes, have a closed "event horizon".

However, unlike a black hole, the curvature of space-time is here at negative infinity, that is, here, the white hole's repulsion to the outside world reaches infinity, and even if the light rushes straight towards the singularity of the white hole, it will bounce back, so it is impossible for it to enter the white hole for a single step.

I think black holes and white holes are like garbage, black holes are a station, useless matter in the universe, and then processed and transformed from the white hole to release material energy, just like processing and then taking it out and buying.

This is my personal idea of black holes and white holes, and I may be able to help you in the future.
