What happens when a black hole could hit the Earth?

Hello Hello Hello Hello Kitty Cat is right, but not entirely.

Before the arrival of the black hole, people will observe the deviation of Jupiter's magnitude first, because the black hole is invisible. Next, radio telescopes will find black holes, and then the Earth will also deviate. Soon, as the gravitational difference between the Earth and its gravity becomes smaller, people will slowly lose weight, so let's enjoy it.

And then, the earth will be spaghetti by it, that is.

The Earth is stretched and torn apart by the tidal forces of black holes, and then slowly swallowed up.

When encountering primitive black holes (miniature black holes, only the size of atoms), small black holes travel through the earth's crust without sucking up much matter along the way. Due to the acceleration of the Earth's gravity, it will grow away from the other side of the Earth, which is certain. Theoretically, due to cosmic radiation.

This happens every day, but it doesn't happen. Because it's so small.

The message you read from **. I haven't found a few black holes, and they have hit the earth. Laugh. Is it "You from the Stars" again? The black hole in there can still cultivate one's self-cultivation. After reading that brain, it is not crippled or crippled.

When the Earth encounters a large black hole, it will be torn apart by the tidal force of the black hole, and then slowly swallowed up. When encountering a miniature black hole, the small black hole will pass through the earth's crust, grow away from the other side of the earth, and if the speed is not fast enough to leave the earth, it will fall back through the earth's crust, go back and forth inside the earth**, and finally stay in the center of the earth and slowly eat away at the earth.

No.

The chances of such a thing happening are slim, but the consequences are devastating. If a black hole with the mass of an asteroid hits the Earth, it will be devastated. Black holes will pierce the surface of our planet like a heated knife piercing butter; On the other hand, a black hole will immediately start decelerating because it will interact with the gravitational pull of the Earth.

Any atom or molecule (or each of us) that passes through the event horizon will slip out of the known universe and will never be seen again. The event horizon is the boundary of a black hole, within which nothing can escape, not even light.

There are three ways to detect a black hole that is close enough to Earth:

First, it can cause strong gravitational lensing, that is, the light rays of background objects near the same line of sight will be bent, stretched, and distorted in a way that is easily recognizable;

Second, it can cause weak gravitational lensing, that is, the surface shape of distant background objects will be distorted, and this distortion will never occur naturally;

Third, it can also cause microlensing, in which case the passing black hole does not obscure the background star, but magnifies its light and causes a temporary but huge brightening.

The biggest feature of a black hole is its super devouring ability, which is given by its powerful mass, and the more massive the celestial body in the universe, the stronger its gravitational pull. Once the gravitational pull is strong enough to reach a certain level, anything that comes close to it will be torn apart, as can be seen from the accretion disk of the black hole, which is left by the decomposition of celestial bodies.

Once the earth enters the scope of the black hole accretion disk, the outer layer will be stripped away, and then the super gravity of the black hole will continue to tear apart and decompose the earth's material, and then become the material in the accretion disk, and then be swallowed by the black hole after a long time. In this case, we will not see the scene inside the black hole.

If the Earth had been lucky enough to fall directly into the black hole at the center, humanity might have seen a different picture. Scientists have long put forward the concept of latitude, the world we live in is a three-dimensional space, and humans are three-dimensional creatures. Einstein's theory of general relativity tells us that the universe is not a calm mirror.

In fact, there are space-time ripples everywhere in the universe, which are caused by the pressure of the mass of celestial bodies on the universe, and the more massive the celestial body, the more obvious the space-time ripples caused, that is, the stronger the degree of space-time curvature caused, in this case, the dimension will be stretched.

After the earth falls into the black hole, the earth will be torn apart by the super space-time force inside the black hole, and the scene that humans can see on the earth is that the whole space is bending. The earth is constantly being pulled up, from three dimensions to two dimensions, and the first dimension finally dissipates. And humans will also see their bodies being infinitely lifted and decomposed like ramen noodles.

Eventually, all life on Earth was completely disintegrated in the process of falling into a black hole.

Even if the other side of the black hole is a white hole, it is possible that the earth will not wait for the opportunity to get out of the white hole, and even if it can, it will go out in the form of particles. It can be seen that the idea of the earth falling into a black hole or humans falling into a black hole and then traveling through time and space to another dimension is basically impossible to realize.

According to the data of scientific reports, there are at least millions of black holes in the Milky Way, which can be said to be quite a lot. However, because the universe is very empty, these black holes do not have a major impact on our planet for the time being. However, these black holes, due to the very strong gravitational pull, have a lot of black holes that have been devouring the material around them, and are even capable of devouring stars.

Whatever the reason, if there is a black hole on Earth, all the matter on Earth will start to fall towards the center of the Earth, accelerating, like in complete weightlessness, free fall. In this process, a singularity appears at the center of the Earth's mass, and the horizon of the black hole forms and expands around it. However, this expansion is not noticeable, because in the end, the Earth completely turns into a black hole with an event horizon of only centimeters in diameter, which is impossible to see if you are not paying attention.

The matter that falls towards the center becomes denser and denser, crossing the event horizon and falling into the singularity. After about 21 minutes, the black hole will be fully formed, which may be somewhat different from the idea of the Earth being torn apart to form an accretion disk and slowly eaten.

<> since everything is falling towards the center of the Earth, when the black hole appears in the center of the Earth, your first feeling is that the body suddenly becomes lighter, suddenly loses weight, and together with the ground, begins a free fall of meters per second, and the truly thrilling final journey begins. Just don't jump out of the air like you do, there's no air resistance to slow you down, even the most experienced athletes, even if you have your hands fully open on one side, even if you're in a hurry with a parachute between them, and you're wearing a winged suit, because everything around you, including the air, is falling at an acceleration of meters and seconds, everything on Earth is in free fall, getting faster and faster, and you have nothing to hold on to – you can't jump on your left foot or pull your hair up.

When you fall halfway to Earth, which is a radius of 3,187 kilometers, you will fly at a speed of 11 kilometers per second, which is about the second cosmic velocity, which is the speed that the spacecraft needs to reach to escape the gravitational pull of the Earth. It's just a coincidence, if you can keep up a faster pace than that, you might survive.

Of course, your best chance is when the black hole is just starting to form and you're about to start descending, and if you can reach that speed, you can escape the black hole, and maybe settling on the moon would be a good option, because if the earth becomes a black hole, the moon won't have any effect. At 10% of the center of the Earth, which is 637 kilometers, you will travel at 34 kilometers per second, which is bad. There doesn't seem to be a rocket that can directly accelerate a spacecraft to this speed.

The earth may be swallowed because the attraction of black holes is relatively strong, and any body that approaches a black hole may be swallowed, and all people or things on the earth will disappear.

There will definitely be fewer and fewer creatures on the earth, and there is a possibility that the earth will happen**, and the environment of the earth is not suitable for human habitation, and it will become very dangerous.

All living things on Earth will perish, and there will be no more sounds, and they will be in darkness all year round.

Black holes are the most mysterious objects in the universe, what if two black holes happen to meet and collide again? What happens when two black holes collide? A black hole is a highly dense region of space where the gravitational pull is so strong that nothing can escape its pull, not even light.

So far, scientists have identified different types of black holes, including supermassive, medium, and microscopic. Stellar black holes are ubiquitous in the universe, with billions of black holes in the Milky Way galaxy alone. One of the special features of black holes is their ability to move freely through the universe, and because of this, there is always the possibility that they will knock each other down.

If such an event occurs, it is clear that the results will be devastating. What happens if two black holes collide will depend on the size and speed of the two black holes, the speed at which they rotate and the angle at which they collide. For example, if these super-rotating black holes collide with each other at right angles, the small black hole will be knocked away by the big black hole, and the small black hole will crash uncontrollably into space.

But if it weren't for the above, the most likely outcome would be that they would not be able to escape each other's gravitational pull and get closer and closer until they began to revolve around each other. In the process, they begin to pull matter and gas into the vortex between them. Over the next few billion years, they will eventually merge with each other to form a new, larger black hole known as a binary black hole.

It's not as simple as it sounds. This is because when two black holes collide in such a way, the energy released by this collision will be so strong that it will cause ripples in the universe in the form of gravitational waves. These energy waves contain eight times more energy than our sun.

This energy is equivalent to the launch of more than 10 trillion atomic bombs per second for 13.8 billion years. So, if such a collision were to occur anywhere near the solar system, the energy from these merged black holes would destroy everything in their path, including Earth. But fortunately, this is unlikely to happen, because the closest black hole to us is called a unicorn, which is about 1,500 light-years away from Earth.

It's very, very far away, you know? On May 21, 2019, the Earth trembled at gravitational waves from the collision of two massive black holes nearly 7 billion years ago. Researchers estimate that the two black holes are 66 and 85 times more massive than the Sun, and the two black holes have merged to form a black hole with a mass 1042 times larger than our Sun.

Since both black holes have the ability to devour things in the universe, when they collide, they produce a huge amount of energy, but at the same time, they also consume each other's energy, causing nearby objects to suffer because of their collision. Of course, it is also possible for two black holes to merge into one under the influence of gravity, forming a larger black hole.

If the black holes collide, they will absorb the material around each other, which may cause a large **.

In fact, the result of devouring each other and merging into one is the same, and the language described is just a difference. It's like the fusion of two drops of water, who devoured whom? It's just scientific terminology for black hole fusion.

The landlord can imagine two shot put balls as two black holes and put them on a thin mattress, then two deep pits will be formed, as if the mattress has two holes. And then what happens when two shot put balls come together? It will form a hole in the mattress that looks bigger, but in fact it is just a deeper hole.

However, ordinary matter such as stars and planets are much shallower than the depressions produced by black holes in space, so the collision of ordinary celestial bodies scatters matter, while black holes do not have this situation. And before the fusion of the two black holes, very strong gravitational waves will be generated, creating ripples in space-time. My analogy is already very simple, and the landlord should easily understand, of course, mentioning gravitational waves by the way.

It has been observed so far.

but no black hole collision has been observed. When two black holes come closer, the big black hole devours the material in the accretion disk of the small black hole and keeps moving closer until the two black holes merge. According to.

The law of black hole area, two black holes fuse to form one.

A new black hole with an area greater than the sum of the areas of the original two black holes.

To put it simply, the gravitational engulfment of the small end of the class may become larger, it may become smaller, it may happen**, and it may disappear

Maybe it's going to come together, I guess. How can a black hole devour the same substance as itself? If you don't like it, don't spray.
