Black holes can be created by humans, and the current experiments on the High Energy Particle Collider can theoretically produce ultra-small black holes, which exist for the same time as Planck time.
The same length, almost no mass, no means of observation, no impact on the world. It is clear that such a black hole is a black hole that has no meaning. The main intent of the question should be whether humans can create black holes for human use.
We can't make natural black holes in the universe, the stars are too big, and secondly, we can't make ultrasmall black holes for high-energy physics, because it doesn't make sense.
<> the birth of a black hole needs to conform to the Schwarzschild radius formula, for example, if you put the Himalayas.
Compressed to the size of a pencil, a black hole will appear, and it is clear that in the future humanity needs to be in the asteroid belt.
To make a black hole factory, first capture enough mass, then accumulate energy for pressurization, and finally through the method of **, for example, the size of the collective mass of igniting a black hole is also particular, and the black hole Hawking radiation studied by Hawking tells us. The smaller the mass of the black hole, the greater the Hawking radiation, and the greater the mass that a black hole will radiate from the black hole, the smaller the radiation will be (presumably that's what it means, I don't remember) So, if a black hole is smaller than an order of magnitude.
The energy radiated will take away all the material on the surface, that is, the black hole closes, stops eating, and the Hawking radiation gets worse and worse, and finally disappears in **.
If a black hole is an order of magnitude larger, and you can't move it by magnetic traction or something like that, you've created something very dangerous for yourself. The meaning of black holes, the creation of black holes, can give physics a new direction of research, and if you can get astrophysicists in touch with black holes, he will definitely bleed with excitement. I think the way we can break through the speed of light is probably to study black holes, because there's nothing more distorted than a black hole.
Black Hole is the perfect waste treatment plant. They eat garbage and spit out energy, with a mass and energy conversion rate of more than 30%. Although humans can create black holes, there must be more ways to dispose of garbage, such as packing it and throwing it into the sun is also a good option.
Black holes in the future of interstellar travel.
also plays an important role.
What if we could use black holes as the core of energy? Run to a new planetary system, feed the black hole something, and keep running to watch The Wandering Earth
Heavy element nuclear fusion.
When I joked, flint.
I'm afraid it's not an electromagnetic field generator made of black holes, otherwise how can you eat stone nuclear fusion. Finally, what kind of technology does humanity need to make black holes? The level of science and technology that compresses a mountain to the size of a pencil tip, artificial neutron star matter is the beginning.

Yes, you must measure the volume of the object, you should pay attention to the speed of the particle accelerator, you should pay attention to the collision between the particles and the particles, after the collision, there is a possibility that a black hole will be generated, you must go to the largest factory in the world. Be sure to pay attention to the volume of the object, the compression ratio.
-
Yes, if you want to make a black hole, you must compress the object to a very small size, pay attention to the collision between particles, and meet the relevant experiments of the particle collider, so that you can create a relatively small black hole.
-
OK. First of all, it needs to have very high-tech means, it takes a lot of time and energy, and then it also needs to be supported and recognized by relevant departments, and then it is also necessary to understand whether black holes are harmful to human beings, so that black holes can be created.

There are currently two types of black holes discovered in the universe. One is a stellar black hole formed by the collapse of a massive star, with masses ranging from 3 solar masses to dozens of solar masses. Another type of black hole is a supermassive black hole, which has a mass of more than one million solar masses and can reach hundreds of billions of solar masses.
In the center of some galaxies, there is often a supermassive black hole, and the protagonist of the first black hole** is a supermassive black hole with a mass of 6.5 billion times that of the Sun, located in the center of the Virgo A galaxy. The formation of supermassive black holes is not yet very certain.
In addition to these two types of black holes, there are also black holes predicted in theory. For example, soon after the universe was large, due to the very dense matter in some areas, these materials directly collapsed to form some primordial black holes, which played a very important role in the evolution and development of the universe, and now those black holes are basically evaporated due to Hawking radiation.
In addition, some scientists who study black holes, including Stephen Hawking, very much hope that humans will be able to create black holes. Humans cannot make stellar black holes and supermassive black holes, after all, the mass of the Earth is orders of magnitude smaller than the smallest stellar black holes, and scientists are eager to create a mini-black hole with a very small mass, which is made by accelerators.
Before CERN's Large Hadron Collider was put into operation, it was analyzed that if the collider had created a black hole, Hawking could have won the Nobel Prize. Unfortunately, until now, the Large Hadron Collider has not created a black hole. China wants to build a more energetic collider, and there is no talk of using a collider to create a black hole.
Maybe it's because the energy is not enough.
A black hole is equivalent to concentrating mass into a very small region, and if two very high-energy particles collide head-on, it is possible to concentrate high energy or mass into a very small region at the moment of collision, and if the mass density of that region reaches a certain level, a black hole will be created.
If such a black hole is created, there is no need for mankind to worry, because the Hawking radiation will cause it to evaporate in a very short time, so short that humans have not had time to detect it. Some say who can guarantee that Hawking radiation is correct? It is true that Hawking radiation has not yet been rigorously proven by experiments, but it is important to know that it is not only Hawking radiation that thinks that black holes with very little mass will evaporate quickly, but other theories also believe so.
Scientists are not worried that black holes can swallow the earth, so why are people worried?
-
Because black holes have played a very important role in the evolution of the universe, those black holes are now basically evaporated by Hawking radiation, so scientists hope to create new black holes. The benefits of black holes are many, not only as an endless repository of garbage into which any garbage can be thrown in, but also as a source of clean energy.
-
In order to study the universe. Because to explore the unknown universe, scientists need black holes. The emergence of black holes provides physical evidence for human understanding of the universe.
-
Black holes are linked to time and space, Stephen Hawking once pointed out that black holes have the feasibility of time travel, and many scientists believe that black holes may be a door to space. Making black holes can enable time travel and space travel. Therefore, studying black holes and making black holes is the pursuit of some scientists.
-
Because to explore the future. Because black holes exist in the universe, this is a feature of the mystery of the universe, and it is also what scientists are trying to explore. Black holes can help humans better understand the development of the universe and the world.
-
Because it is necessary to study the causes of the formation of black holes and the role of black holes, it is necessary to create black holes. Research activities play a very important role in human beings to decipher the mysteries of the universe and travel through time and space.
-
It is possible to create black holes on the earth, because we don't know much about the earth, and there are many places on the earth that we haven't explored, so I believe that black holes can definitely be made in these places.
-
There is no possibility, because the temperature of the Earth and the temperature of the black hole are completely different, the attraction is completely different, and there is gravity on the Earth, so there is no way to meet such a standard.
-
It is impossible, because black holes are very mysterious, and the matter inside has not been studied clearly, so it is impossible to create a black hole.
-
To put it simply, to form a black hole, the volume and mass of the star must be large enough, otherwise at most it will only form a neutron star or a white dwarf, and then there will not be enough gravitational force to form and collapse again.
A black hole is formed when the remains of a star 'erupt' are at least twice as large as the Sun.
In the remaining 10% of a star's life, it will gradually become hotter (and more energy will be released). Due to its own mass, it will generate a large gravitational force; As a result, a star can only rely on its own nuclear fusion to produce energy to balance its own gravitational pull. But when its own energy is used up, its own gravity becomes the dominant force, and the lack of force to compete with it leads to the collapse of the star itself, resulting in a more complete collapse (when the mass of the star is smaller, the collapse is not so complete).
A star the size of the Sun will only become a white dwarf, while a debris with more than twice the mass of the Sun will become a neutron star), thus becoming a point with infinite gravity and gravity. Any substance will be sucked in.
And because of its gravitational pull, even the fastest light in the universe can't escape. So, if the light is not reflected, we can't see it. Therefore, it is called a black hole.
Dark matter, like black holes, makes up about 90% of the total mass of the universe. They include white dwarfs, black dwarfs (that is, white dwarfs are completely cooled, but this will take about 100 million years), neutron stars, black holes, cosmic strings (which are the folds in cosmic space, where scientists estimate that there is no life), and so on.
Dark matter plays a large role, it is able to attach to galaxies or clusters of galaxies. Thus controlling the speed of expansion of the universe. If the dark matter is more than 99%, all matter will be restored to a point. Therefore, dark matter is also known as cosmic glue.
When you fall into a black hole, it may be due to the force of space-time distortion - in a certain way.
The sides will squash you and stretch you out in some other direction until you look like spaghetti. But what exactly happens inside. Nothing is known to the current physics community.
To make it simpler, we can think of the universe as a sheet of bed with four people pulling its sides tight, and the star is a bowling ball, and when the bowling ball is placed on the sheet, the sheet collapses, but not enough for the sheet to collapse too much. Then you imagine that the bowling ball becomes the size of a grain of rice and its original mass does not change, and if the sheet is tough enough, the 'ball' will start to collapse too much, and when you put anything on it, it will move towards the collapse of the rice grain, which is why the black hole attracts anything.
Of course, this metaphor is not enough to be vivid, but the general meaning is this!!
According to Einstein, the reason why black holes attract any matter is not because it has a large gravitational pull, but because black holes make space collapse very seriously, as long as it is within a certain range of the black hole, it will move towards the black hole due to the collapse of the nest.

The number in the figure stands for no.
Qubit (Qubit), the smallest unit of positive and negative electromagnetic information that is revisably partitioned, is a qubit (named physicist John. John Wheeler famously said, "It from bit."
After the development of quantum information research, this concept was sublimated to the point that everything originates from qubits) Note: Bits are bits.

Humans cannot destroy the planet.
Because, no matter how powerful human beings are, they can't really destroy the earth, as far as the current level of science and technology of human beings is concerned, human beings have not even reached the ability to destroy half of the earth, let alone destroy it, even if human beings have more nuclear **, but only the surface of the earth will be harmed. >>>More
