The principle of the white hole is that there is a strong gravitational field around the white hole, which attracts nearby dust, gas and radiation to the boundary and produces high acceleration, thus colliding with the material particles ejected from the white hole at high speed and producing huge energy radiation. X-rays, cosmic rays, radio bursts, dual radio sources and other high-energy phenomena can all be regarded as the result of the interaction between the white hole and its surrounding accretion substances. Interpretation of cosmic background x-rays and? The energy spectrum of the X-ray source is also close to the observation results.
The radiation emitted by the swelling substance in the white point has the characteristics of purple shift, especially in the initial stage of swelling. Regarding the origin of the white hole, one view holds that the ultra-dense matter in the white hole is obtained when the gravitational collapse forms a black hole. After some internal contradictory movement, they are transformed into an expansion state and then driven out of the central singularity. The popular view is that the white hole originated from the Big Bang of the whole universe. When the universe explodes from the ultra-dense state, some ultra-dense substances are still in a strange state after being thrown out because of the non-uniformity of the explosion. They can wait for a certain period of time before they begin to expand and explode, becoming a new local expansion core. The explosion time of some cores was delayed by about 10 10 years (100000000 years, i.e. 1000 billion years). Once they explode, they form quasars or other high-energy celestial bodies that can be observed today, so white holes are also called? Delayed nucleus? . With the development of cosmology, people will further unveil its mystery.
By definition, white holes and black holes were put forward by physicists on Einstein's general theory of relativity based on black holes? Imagination? An object, or a mathematical model. Physical circle
Astronomy defines a white hole as an ultra-dense object, which is completely opposite to a black hole. The white hole does not absorb external matter, but constantly ejects all kinds of interstellar matter and cosmic energy to the periphery, which is the jet source in the universe. Simply put, the white hole can be said to be a black hole with time reversal. The matter that enters the black hole should eventually come out of the white hole and appear in another universe. Use and? Black? The cave is completely opposite in nature, so it is called? White? Caves; Because the gravity of the black hole makes it impossible for light to escape, and the white hole and the black hole are completely opposite (even light will be excluded), it appears white and is called a white hole. It has a closed boundary, and the materials gathered in the white hole can only move outward, not inward. Therefore, the white hole can provide material and energy to the outer zone, but it can't absorb any material and radiation from the outer zone. White hole is a strong gravitational source, and its external gravitational properties are the same as those of black hole.
White holes can absorb the surrounding materials to the boundary to form a material layer. White hole theory is mainly used to explain some phenomena of high-energy celestial bodies. At present, astronomers have not actually discovered the white hole, which is just a theoretical term. Theoretically, white holes are obtained by analogy with black holes. Scholar? Theoretical products are more represented as mathematical models.
Unlike black holes, white holes don't absorb anything. On the contrary, white holes constantly release substances, including elementary particles and fields.
White holes, like black holes, have a closed one? Vision? . But unlike a black hole, the curvature of spacetime is negative infinity here, that is to say, the repulsion of the white hole to the outside world is infinite here. Even if the light goes straight to the singularity of the white hole, it will bounce back, so it can't enter the white hole.
In theory, white holes can also be classified according to whether they rotate or not, but theoretical physicists believe that the infinite repulsion of white holes will force them to have no charge, because the charge can be easily driven out of the horizon. Rotation is also considered impossible. But it seems that the white hole can only be an imaginary product. Because if the white hole does not absorb anything but only ejects matter (energy), then no matter how big the mass of the white hole is, its matter will be ejected quickly.
Of course, physicists also provide several ideas for the existence of white holes. Some of them think that the white hole and the black hole are connected by wormholes, so that the mother universe and baby universes can get in touch. For this mechanism, you can refer to About? Time wormhole? Overview (see Hawking's The Universe in the Shell for details).
Does the white hole still exist? White hole? It is just a theoretical term, and scientists have not actually discovered it. Technically, it is much easier to find black holes, even supermassive black holes, than to find white holes. Maybe every black hole has a corresponding white hole! But we're not sure if all the super-quality ones. Hole? Both? Black? Holes, and it is not certain whether white holes and black holes should appear in pairs. But from the point of gravity, from a distance, the characteristics of the two are the same.
When people have complex mathematical tools to analyze these related equations, they find more. In this simple case, the space-time structure must have time reversal symmetry, that is to say, if time to go back is allowed, everything should be the same. Therefore, if at some point in the future, light can only enter but not exit, then there must be a period of time in the past when light can only enter but not exit. This looks like the inversion of a black hole, so people call it a white hole, although it is only an extension of the black hole in the past. What's more strange is that there seems to be another universe in the world, although it is used here? Inside? It may not be exact. Time exists in a white hole, but since you can't get in, you can only know if you were born in it.
But in reality, white holes may not exist, because real black holes are much more complicated than the simple solution of this general theory of relativity. They did not always exist in the past, but were formed after the collapse of stars in a certain period. This destroys the symmetry of time reversal, so if you look back, you won't see the white hole described in this solution, but the black hole will turn back into a collapsed star.
We know that because of the strong gravity of a black hole, it can suck up any object nearby, and it can only enter but not exit. What if we treat a black hole as a black hole? Entrance? So, there should be one who can't get out, right? Quit , the so-called? White hole? . The passage between a black hole and a white hole also has a proper term called? Grey road? (That is? Wormhole? Alias? Silicon hole? )。 Although the white hole has not been discovered, the most beautiful thing in scientific exploration is that many theoretically existing things have been discovered or confirmed later. So, maybe one day, with the progress of science and technology and the continuous exploration of human beings, astronomers will really find the existence of white holes!
The relationship with black holes White holes and black holes complement each other and are the unity of opposites. Shen Ben discusses the relationship between black holes and white holes in the article "Comparison between Black holes and white holes" as follows: Hawking pays attention to black holes, but his hypothesis may give the idea of mutual transformation between black holes and white holes cheap. Of course, this idea is mainly due to the symmetry of black holes and white holes; Because the collapse of matter into the central singularity and the explosion of matter from the central singularity are two opposite and complementary processes, it seems that it is still possible to instantly turn a black hole into a white hole. For the evolution of the universe, we make the following tentative explanation. An evolutionary model derived from general relativity assumes that the universe was born from the big bang of the primitive fireball, then expanded, expanded to the maximum, and then collapsed to the minimum; Then the second explosion and its expansion and contraction process; This cycle goes back and forth. For this model, can the original fireball of each explosion be regarded as an original white hole, which is instantly transformed by the termination of the last collapse process? The starting point and ending point are the central singularities of white holes and black holes. ? This exposition contains profound dialectical logic thought.
Based on the above, we can draw the following conclusions:
First of all, black holes are an extreme phenomenon and attractive form in the universe. What is its direct result? Crash? On the contrary, the white hole is an extreme phenomenon and form of exclusion in the universe. What is its direct result? Big bang? Or? Big expansion? . Both of them are indispensable, closely linked, complementary, mutually transformed and unified by opposites.
Second, black holes and white holes are through some kind of? Limit change mechanism? (Worm eye mechanism, etc. ) are mutually transformed. Due to this mutual transformation, all material phenomena in the quantum ladder can be generated, developed and disappeared. In this process, there are neither immutable and eternal things, nor things that only appear once and become extinct forever. What happened will die, what died will be born again, and so on.
Third, the mutual transformation between black holes and white holes is the most fundamental and important source of power for the evolution of the universe. Their existence and transformation, right? Attract and repel this ancient bipolar opposition? Vivid embodiment is the deepest source of all things' changes.
A black hole is like a bottomless abyss in the universe. Once a substance falls in, it can never escape. According to what we are familiar with? Contradiction? Scientists boldly speculate: will there be a substance in the universe that just can't get out? Spring? And then what? And gave it an opposite name to a black hole, called. White hole? .
Scientists suspect that the white hole also has a closed boundary similar to a black hole, but unlike a black hole, the matter and radiation inside the white hole can only move outside the boundary, while the matter and radiation outside the white hole cannot enter its interior. Figuratively speaking, the white hole seems to be a source of constantly spraying matter and energy. It provides matter and energy to the outside world, but does not absorb it.
So far, the white hole is only a guess of scientists, and no evidence of its possible existence has been observed. There is no major breakthrough in theoretical research. However, the latest research may come to an exciting conclusion, namely:? White hole? That's about it? Black hole? Itself! In other words, a black hole absorbs matter at this end and ejects matter at the other end, just like a huge time tunnel.
Scientists have proved that it is actually possible for black holes to emit energy. According to the theory of modern physics, energy and mass can be transformed into each other. This is theoretically predicted? Black holes and white holes merge? This possibility.
