Why did a dead planet become a black hole?

It doesn't turn into a red giant, it's just that the shell expands, time collapses, the curvature of space is nearly infinite, parallel worlds collapse, and the white hole theory appears.

Through prolonged ejection, the black hole will eventually become nothing, disappear, and die. Black holes will glow brightly and shrink in size.

The Earth, as a planet, does not become a black hole after death unless it is sucked in by a black hole.

Black holes are formed as a result of collapsing stars, but not all stars can form black holes. Different stars evolve other different processes, depending on their mass. Only very large stars can form black holes at the end of their life cycle.

Stars are initially kept active by burning fuel from their cores, but once they run out of fuel, the gravity on the star acts in turn on itself, causing the star to become a stellar black hole.

The Earth can also become a black hole, but only if all of the Earth's mass is compressed to within millimeters. The Earth will not evolve into a black hole on its own, unless in the future the Earth becomes much larger than it is now for some reason. Even our sun is not big enough to form a black hole.

No, it won't. The Earth will never turn into a black hole, all black holes are a singularity, infinitely small, and have no volume.

But any object has a Schwarzschild radius, also known as an event horizon. This is the exact solution of the gravitational field of any object, an important concept in the theory of relativity, a critical radius value that exists for all objects, and any object, once reduced to this critical value of its own, will inevitably collapse into a black hole infinitely. Both the Earth and the Sun, although they cannot be black holes, both have Schwarzschild radius.

Stars with a mass of less than 8 times, including the Sun, will not have a supernova because the mass is too small and the central pressure is not enough, and will expand into a red giant, and eventually the prosperity will be dispersed, and the center will shrink into a white dwarf, about the size of the Earth, but the mass is more than 100,200,000 times that of the Earth, and the density of the material on it reaches 1 10 tons per square centimeter.

No, the Earth will expand dramatically, eventually**.

When the Earth dies, it will disappear from the universe and will not become a black hole, and it may also decompose.

Does Earth become a black hole when it dies? Who knows this question, the earth where human beings live is a planet, so will the planet become a new celestial body after death? The outcome of the death of a planet comes as a surprise to many people, and the death of a planet is not the end, it will be passed on in another way.

It can also be understood in this way, but the death of a star does not necessarily turn into a black hole. It is possible to become a white dwarf or neutron star, or a red giant.

It can be understood in this way, and this metaphor is also very vivid, because black holes are bottomless in the first place, and the danger factor is relatively high.

It can be understood in this way, because the star is a black ball, and it is black, there is nothing, and you have not found anything now.

Of course, that's understandable, and I think the black hole is indeed a black ball, and it's a mysterious black ball.

It can be understood in this way, because black holes are originally a very magical being, and they swallow a lot of things.

Nothing in the world is eternal, we will also experience birth, old age, sickness and death, disappear in the world, and nothing in the universe is eternal, as the most mysterious black hole in the universe will not escape, so the following reasonKnowledge of horoscopesHow did a black hole die? What does a black hole end up in?

How black holes die.

In Hawking's theory of black hole evaporation, it is mentioned that black holes will also emit matter outward, and due to the divergence of matter, the black hole will eventually "die". In general, the greater the mass of a black hole, the shorter its lifetime.

The larger the black hole, the slower it evaporates, and vice versa, the faster it evaporates. A 100-ton black hole will disappear without a trace in 1 million years, and a 10-billion-ton black hole will disappear without a trace in 10 to the 60th power. In a black hole, all matter breaks down neutrinos and tiny particles and ejects them through the poles of the black hole.

Through prolonged ejection, the black hole will eventually become nothing, disappear, and die.

Black holes will shine brightly, shrink in size, and even **. When British physicist Stephen Hawking made this prediction in 1974, the entire scientific community was shaken. Black holes were once thought to be the ultimate precipitation of the universe

There is nothing to escape from black holes, they devour gas and stars, and their mass increases, so the size of the hole only increases.

Black holes don't stand still all the time. Quantum effects suggest that black holes are not strictly black, but are emitting a faint light all the time through thermal radiation. A black hole as massive as the Sun, whose temperature is pitifully low, is only minus 10 billionths of a degree of absolute temperature, and when the black hole collides with other objects or other black holes, there is still some activity, and the rotation of the black hole gradually slows down as the black hole's spin is consumed.

However, the most drastic changes occur when the temperature of space drops below the temperature of a black hole.

What does a black hole end up in?

A black hole that is hotter than its surroundings loses heat and therefore energy. The loss of energy will cause the black hole to contract. The contraction of the black hole will increase the temperature slightly, which will accelerate the energy radiation.

As a result, the black hole begins an uncontrollable evaporation process. For an extremely long time, the rate of contraction of black holes has been climbing upward, and finally, after about 10e108 years, those black holes that were originally heavier than many galaxies combined will shrink completely without a trace.

Black holes don't die, black holes are infinite, and black holes can exist for a long time, so they can't die.

Black holes also die, although black holes are invincible in the universe, if a black hole collides with other stars, it can absorb and tear other stars apart, but the lifespan of a black hole is not eternal.

Any object has to go through 4 stages of birth, growth, aging, and death, and black holes are no exception.

Summary. Black holes do die eventually, but for a long time. And we don't know exactly what will happen in the end, because we have never seen it with our own eyes.

According to some theories of the end of the universe, black holes may one day be left with only black holes left in the universe because they are so long-lived that they have devoured everything that has ever existed in other forms. It's a hopeless but fascinating view. Luckily, we still have a long, long time to go between now and then.

Do black holes die?

Black holes do die eventually, but for a long time. And we don't know exactly what will happen in the end, because we have never seen it with our own eyes. According to some theories of the end of the universe, black holes may one day be left with only black holes left in the universe because they are so long-lived that they have devoured everything that has ever existed in other forms.

It's a hopeless but fascinating view. Luckily, we still have a long, long time to go between now and then.

When we think of black holes, we think of images of black holes devouring matter. In fact, black holes, especially supermassive black holes, have many celestial bodies around them, most of which are stars. But because stars move fast, they are generally not swallowed by black holes.

However, if the trajectory of motion is changed due to collisions and other reasons, it may be ruthlessly swallowed by the black hole. So, what about the matter that was swallowed by the black hole in the end? It doesn't disappear for no reason, does it?

We now know that while black holes continue to devour objects, they will eventually evaporate through Hawking radiation. So after the black hole disappears, the object that is swallowed by the black hole goes? Scientists can only guess at this question.

One view is that the engulfed object disappears in the form of a black hole evaporation because in the process of evaporation of the black hole, energy is constantly radiated outward, and energy and mass are one thing in themselves. There is also a more sci-fi speculation that there are not only black holes, but also even more bizarre celestial bodies: white holes.

White holes are the opposite of black holes, which devour objects mercilessly, while white holes constantly "spit out" objects. There is also a view that directly treats the black hole, the white hole, and the wormhole as a whole, the black hole and the white hole are connected through the wormhole, and the black hole devours the object and then wears it.

So the problem of black hole engulfment will eventually disappear as well.

The natural world is composed of matter, and so is man, and the matter swallowed by the black hole will eventually disappear, so it also includes everything in nature, without exception.

Nature does not include all, but everything in the world is made up of matter.

Everything that the black hole swallows will be gone.
