How small can the smallest black hole be, and how big would it be if it swallowed the Earth?

The smallest black hole may be about the size of an atomic nucleus, but nevertheless. With such a small black hole, the change in the volume of the earth should have little effect. It's more about emitting matter and energy into the universe through gamma rays as they are swallowed into the earth.

The smallest black hole has an event horizon of only centimeters in diameter, and if the black hole swallows the Earth, it can only become a black hole about 3 centimeters in diameter.

I think the smallest one is as small as Mercury, and it won't get bigger if you swallow the Earth, because black holes are very dense objects, and everything compresses.

The data shows that the kinetic energy required to create a mini-black hole is 1015 times more than the limit of the Large and Medium Hadron Collider. What if people grasped a certain amount of technology and used such tremendous kinetic energy to create miniature black holes?

As we all know, a black hole is a relatively dense star, even if its diameter is only 1 millimeter, the mass is very large, about 11% of the mass of the Earth, and the sum of the mass of the five moons is not as good as it.

If there were a black hole on Earth with a size of 1 millimeter, what would it produce?

This small black hole has about 1 to 1% of the mass of the Earth. Therefore, the accretion disk of this black hole is relatively small, so if it is as far away as the moon, there will be no major harm to the earth, but if it touches the earth, it will be immediately pulled by the earth's attraction to the core, and then gradually swallow the earth at the core, but this whole process will take a long time, and it is very likely that the solar system will not be destroyed. Then there is a strange view of a black hole in Earth's orbit turning into a large solar planet.

The emergence of black holes has given mankind a new understanding of black holes. In the previous plan, we also discussed what happens to black holes in the solar system. Because black holes have too much influence on celestial bodies, if a black hole occurs in the solar system, the solar system will no longer exist. <>

Because the orbiting speed of the same central star is not the same in the semi-longitudinal category, the closer it is to the center, the faster the rotational speed ratio, and the more it avoids the center, the slower the rotational speed ratio, thus causing the inner layer of matter to be slowed down by the outer layer of matter and falling to the black hole in the orbit, and its parabolic motion will be transmitted to the outer layer, resulting in the rotation speed ratio of the material disk becoming faster and faster with a large amount of matter falling, and migrating to higher tracks.

With the fall of a large amount of matter, the radius of the material disk will become larger and larger, because the radius expands, the rotation speed of the matter in the material disk is too low, it will shrink, and the friction will also decrease, and the inner matter will not be relatively easy to be slowed down by the outer matter and fall into the black hole.

There will be a particularly big catastrophe, the earth will be destroyed, humanity will perish, and the civilization on the earth will disappear.

I don't think anything will happen because this black hole is very small, so it can't be a big threat, it doesn't have much impact.

If there is a black hole on the earth that is 1mm smaller, this black hole will continue to devour things on the earth, gradually become larger, and eventually swallow the earth.

Then all the matter on Earth can be sucked into a black hole, because the energy of a black hole is immeasurable, and you don't know what the consequences of a black hole of this kind will be.

There are no consequences, after all, a millimeter of black hole is too small to absorb the vast amount of matter on Earth.

If there is such a black hole, if it goes on like this for a long time, the hole will become bigger and bigger, and then it will suck a lot of things into it, and in this case, it will cause a kind of destruction of the earth.

When you think of black holes, you will have a big black hole in your mind, which can swallow everything and has extremely destructive power. So what would happen if a one-hundred-centimeter-long black hole approached Earth?

When a star is massive enough, after the hydrogen fuel burns out, its center collapses, and at the same time the density increases, and the gravitational pull becomes so strong that it can absorb everything around it. Not even the speed of light can escape from it, unless, of course, it encounters a black hole larger than it. In the case of the Sun, for example, if its mass persists, its radius would have to be reduced to 232,000 times before it becomes a black hole.

A 1 cubic centimeter black hole may seem the size of a glass sphere, but the quality of practice should not be underestimated! If this one-hundred-centimeter-long black hole were to approach the Earth, it would absorb all the material on the Earth and swallow it whole, making the Earth a part of the black hole, and the black hole could become three times its size. It's not just the Earth, it's the same thing when you put it on the Sun.

The composition of a black hole requires a certain quality. Black holes made up of stars have the lowest mass of a sun. According to the Schwarzschild radius formula, it has a radius of 9,420 meters, which is obviously much larger than 1 cubic centimeter.

Currently, the smallest black hole ever discovered is a solar mass. At the beginning of the universe, due to the very high density of matter and energy in space, black holes could be created with just a little disturbance, and the mass of these black holes could be large or small. This is the primordial black hole.

After 13.8 billion years, primordial black holes with very small masses either absorbed mass and became larger, or were evaporated by Hawking radiation. But it is unadmittedly that objects of any mass can be condensed into black holes, as can also be seen from the Schwarzschild radius formula.

However, according to current research, there is no black hole as small as a cubic centimeter in the universe. The smallest black hole found so far is a stellar black hole, which has three times the mass of the Sun. Although this is just a brain hole of people, as scientists learn about the universe from time to time, the level of human cognition will improve from time to time, and all the mysteries of the universe will have an answer.

I don't think such a black hole will swallow the earth if it is close to the earth, because although the energy in such a black hole is very extensive, because its size is too small, it will not cause inflammation to the earth, and when it is close to the earth, it will be attracted by the external gravitational attraction of the sun.

Yes, the gravitational pull of a black hole is very strong, and once it gets close to the Earth, it will definitely swallow the Earth.

Yes, there is no way to imagine the process of devouring the Earth, and it is possible for a black hole to encounter any matter that is swallowed.

Any object with mass has a characteristic value of a critical radius, below which it will collapse indefinitely into a singularity, an extremely dense singularity, the so-called black hole. General relativity is an infinitely large black hole, it is an infinitely large black hole! The critical radius of a black hole is also known as the Schwarzschild radius and the event range radius.

Any object that invades the radius of the black hole's event horizon will fall unconditionally towards the singularity, and even photons without a resting mass will not be able to escape! Black holes are the abyss of violence, greedily devouring everything in the universe! What would happen if there was a black hole on Earth with a diameter of 1 millimeter?

Although the mass of a black hole is concentrated in the singularity, because the singularity has no size, it is scientifically described as infinitely small in size, infinitely high in density, infinitely large in curvature, and infinitely high in temperature.

No matter how big a black hole is, the singularity is infinitesimally small. But depending on the mass of the black hole, a spherical gravitational field of infinite curvature will form around the singularity. Once in this gravitational field, nothing can return, not even light at 300,000 kilometers per second.

The critical radius was calculated by the German physicist and astronomer Karl Schwarzschild in the early 20th century using a vacuum solution to the gravitational field equation of Einstein's general theory of relativity. This ball of dark gravity is known as the Schwarz radius. The radius is directly proportional to the mass, and the greater the mass, the larger the radius.

Everything next to this black hole will be pulled by gravity, everything will be swallowed by the black hole, and eventually this earth will be destroyed, and human beings will no longer exist.

The Earth will be swallowed by this small black hole because the gravitational pull of the black hole is extremely strong and it will swallow the surrounding stars.

Unexpected things will happen, there will be a certain amount of chaos on the planet, and there will be a certain amount of panic among everyone.

First of all, there is a problem with the topic, in reality, "one centimeter in diameter" cannot form a black hole at all。You know, even if the Earth were to become a black hole, the whole Earth would need to shrink to centimeters in diameter, so the substance described in your title is just a very dense substance, not a black hole.

Let's assume that the title is talking about a sphere with a diameter of one centimeter and a mass of one tonThen its volume is, according to the formula for calculating the volume of the sphere: v sphere = (4 3) r 3, r is the radius of the sphere, so the volume of this object is obtained: cubic meters.

If the mass is one ton, then the density of this substance = m v = 1000kg cubic meters, density = 1912045889kg m 3, 1912kg cm 3, that is, tons per cubic centimeter, this density is higher than the density of any kind of matter we usually see, almost the density of matter on white dwarfs.

White dwarf is the product of the end of the evolution of low-mass stars, when the mass of the white dwarf exceeds the mass of the sun, it will evolve into a neutron star, the density of the neutron star is much larger than that of the white dwarf, on the neutron star, the mass per cubic centimeter can reach hundreds of millions of tons, which is very exaggerated, and the further collapse of the neutron star may evolve into a quark star (theoretically), a black hole.

It can be seen that the hypothetical mass of one ton and one centimeter in diameter is far from reaching the level of a black hole.

For example, it is actually the level of water droplets in the three-body problem。If it is put on the earth, of course, it is an indestructible material. There is no way to destroy it on Earth, it can easily crash through rock formations, any metal barriers, and of course, you need to give it initial kinetic energy.

But all it can do is penetrate.

And black holes not only need to break through the electron degeneracy pressure, but also need to break through the neutron degeneracy pressure, and then go further! is a more extreme case than this material. If it were one centimeter in diameter, it would have the mass of about the size of the sun.

In this way, it can become a black hole and can devour any star that comes near it.

Of course, such a small ball, if it flies to the earth, can easily penetrate the earth and sink into the center of the earth, and finally reach gravitational equilibrium in the core of the earth and stay in it forever.

The mass is very large, there may be darkness, it will affect the earth, it may swallow the earth, there will be different changes, and there will be different lighting conditions.

A black hole with a diameter of one centimeter is about a ton.

If it is close to the Earth, the Earth's material will be torn apart, triggering tidal disintegration events.
