It is said that this is related to the generation of the universe, according to the theory of the universe, the existing universe is produced with a singularity, which is equivalent to "0" in mathematics, and ** after the production of space and time in the universe, and this "0" is decomposed into +n (positive matter) and -n (antimatter), the so-called world we currently know, the universe is composed of positive matter, antimatter is its relative thing, invisible, in recent years, scientists have confirmed its existence, and can be generated.

Let's see for yourself, it's complicated, I just know that what we can see and touch is positive matter, positive matter meets antimatter, 100% energy is released, and it is completely annihilated. You know, the atomic bomb uses only 5% of its energy, for example? It's very simple, antimatter the size of a penny is enough for the space shuttle to take off and land safely 50 times, enough for a car to travel billions of kilometers, and the engine is the size of a matchbox, and it's pollution-free, to put it bluntly, it's the cleanest energy source, but it's extremely difficult to get Fermi National Laboratory in the United States, which is mass-producing antimatter atoms 50w protons are accelerated to 95% or 98% of the speed of light with a particle accelerator Forget about hitting the copper plate, it seems that there is a probability of producing 1 antimatter atom and it has to run at that speed all the time after it is generated, so it can be said that it is difficult to store Now it seems that there are 4 5,000 antimatter atoms It seems that somewhere in Europe or Australia is building an institution similar to Fermi National Laboratory I heard that the production is higher It is expected to be completed around 2020 Some people think that antimatter is in a quiet place Just dig a pit on the spot Dig and dig and dig very deep Look for it in a water tank, do you say you can find it, of course it fails, antimatter is heard to exist in the halo of galaxies, and a lot of people think that looking at a certain galaxy, using that law (forgot) to calculate the mass of the galaxy as... Forget about 100% first) But only about 3%-8% can be observed with the naked eye, and the rest is not observable by humans for the time being, so some scientists think that the rest is antimatter, and I think it's, because if it's really antimatter, then it's a planet, 100% energy burst, you know, it's n times bigger than the sun, and the planet n is more than the sun, and its power can't be observed by the earth? So what is that 97% I don't think there will be a lot of antimatter I'm just guessing Wait for our son's descendants to solve it We can only guess There are still a lot of lazy typing Go and see** Bao you have learned a lot I have something new to tell me.

Encyclopedia Introduction:
Antimatter is the anti-state of normal matter. When positive and antimatter meet, the two sides annihilate each other and cancel each other, occurring ** and generating a huge amount of energy.
Positrons and negative protons are both antiparticles, and they have the same amount of electricity but opposite electricity compared to electrons and protons. Scientists imagine that there could be matter in the universe that is entirely composed of antiparticles, that is, antimatter. Electrons and antielectrons have the same mass but have opposite charges.
The same is true for protons and antiprotons. Particles and antiparticles are not only opposite in charge, but also in all other properties that can be reversed.
The British journal "Nature" published a research report on the 17th that scientists at the European Center for Nuclear Research (CERN) have successfully created a number of antihydrogen atoms and used magnetic fields to make them exist for a "long time". This is the first time that scientists have succeeded in "grabbing" an antimatter atom.
The hydrogen atom is the simplest atom with only one proton and one electron. In fact, CERN created the first anti-hydrogen atom back in 1995, but it only existed for a few microseconds before it collided with the positive hydrogen atom in the surrounding environment and annihilated. The breakthrough was that after creating several antihydrogen atoms, they succeeded for the first time in keeping them in existence for a "long time" of about 0 17 seconds with the help of a special magnetic field.
My description: There are electrons, positrons, protons in matter, antiprotons, neutrons, antineutrons, ......
When an electron touches a positron, it is annihilated and photons collide.
Everyone knows what electrons are talking about, so what is a positron?
The composition of positrons and electrons is exactly the same, with the only difference from electrons, that is, the direction of rotation is different from electrons.
The direction of rotation of the positron is completely opposite to that of the electron, so the magnetic poles are also completely opposite.
For example, the n pole of the positron points to the north, the s pole points to the south, the n pole of the electron points to the north and south, and the s pole points to the north. The two are close, and of course the n pole and the S pole attract each other, and soon collide with each other, and after the impact, both are smashed into pieces, and these fragments are photons. Because they are all made up of photons.
Protons and antiprotons, the same way.
Neutrons are the same as antineutrons.
All matter is the same as antimatter.
Summary: Antimatter and the corresponding positive matter are the same in mass, shape, structure, and rotation speed, but the difference is that the direction of rotation is different. Due to rotation, the positive matter has a magnetic field, and has the n and s poles, and the antimatter is equivalent to turning the positive matter upside down, so that the rotation direction of the antimatter is opposite to the positive matter, and the direction of the n and s poles is also opposite to the positive matter.
In this way, the n and s poles of positive matter and antimatter are attracted to each other, and then the positive matter and antimatter collide violently, and annihilation may occur and photons are released.
Antimatter can be generated directly, or it can be reversed by a certain method to become antimatter. )

Antimatter is an imaginary form of matter, made up of antiparticles.
To explain the concept of antimatter, we must first understand particles and antiparticles. From the microscopic origin of macroscopic objects in the natural world, they are all composed of protons, neutrons, and electrons, and later someone discovered electrons that are positively charged, and then with the discovery of antiprotons and antineutrons, people became aware of the existence of antiparticles.
The next step is to explain antimatter, which is an imaginary form of matter, which is an extension of the concept of antiparticles, which are made up of antiparticles. The combination of matter and antimatter, like the combination of particles and antiparticles, causes both to annihilate and release high-energy molecules, or gamma rays.
What is the role of antimatter
Antimatter is rare. But its role in the formation of the universe was enormous. Scientists believe that matter and antimatter exist in equal amounts.
However, with the passage of time, matter has become a major factor in the composition of the universe. Antimatter has been replaced. Why this happens remains a mystery, and modern scientific models cannot fully explain this discrepancy.
However, we have something to be thankful for. If in the early days of the universe, antimatter and matter were equal, their collision would have destroyed each other long ago. Well, our world simply doesn't exist.
As a result, antimatter has proven time and time again to be an exciting concept and continues to haunt the greatest minds on Earth.

In 1928, the British physicist Paul M Dirac proposed the hypothesis that the electron's antiparticle ———positron. In 1932, American scientist Carl Anderson accidentally discovered a special particle in an experiment, its mass and charge are the same as those of electrons, but it is positively charged, while electrons are negatively charged. Hence, people call it positron.
Later, scientists discovered antiparticles of protons, neutrons, mesons, hyperons and other particles. The discovery of various antiparticles has prompted people to ponder the question: since the atoms of various elements are composed of "positive" particles such as neutrons, protons, and electrons, is it possible that there are also antielements composed entirely of antiparticles?
After thousands of experiments, scientists finally discovered the isotope "gas deuterium" and the isotope "anti-helium" "anti-helium" "anti-helium-3" in 1965. With anti-elements, it is possible to make antimatter molecules that are made up of anti-atoms of anti-elements.
However, scientists have not been able to obtain these antimatter. Because, in the world around us, as soon as antimatter appears, it immediately combines with "positive" matter and annihilates extremely quickly. So, is there any antimatter in nature?
According to the view of matter antimatter symmetry, the amount of matter and antimatter in the early universe should be equal, but human beings have not yet observed space antimatter. Whether antimatter exists or not has always been a mystery in science.

The concept of antimatter was first proposed by the British physicist Paul Dirac.
In the thirties of the twentieth century, he predicted that every particle should have an antiparticle against it, such as an antielectron, which has exactly the same mass as the electron and carries the opposite charge (a). And the spin quantum number of the electron is -1 2 instead of positive 1 2.
The European Space Agency's Gamma Ray Astronomical Observatory has confirmed the existence of intercosmic antimatter. They made a careful observation and analysis of a region of the universe. It was found that a large amount of antimatter was concentrated in this area.
In addition, the Gamma-ray Astronomical Observatory has also proved that there are many of these antimatter**, and that it is not concentrated around a certain point, but is widely distributed in the universe

Actually, Einstein came up with it.

Compared with the electrons and protons of all matter in the universe that we know, antimatter has the same electricity but opposite electricity. What happens when antimatter and positive matter meet? They will destroy each other, the two particles will disappear, and their masses will be completely transformed into particles carried by some kind of high-energy force, such as photons or gluons.
We call this process "annihilation."

On October 30, 1979, American scientists used scientific detection materials in high-altitude balloons to measure 28 antiprotons, discovering antimatter in nature for the first time. So, what is antimatter?
In 1928, the British physicist Dirac discovered the existence of antimatter. Dirac claimed that for every ordinary particle of matter, there is a corresponding antiparticle, both of which have the same mass but carry opposite charges. These antiparticles can combine to form antiatoms, which in turn can further form antimatter, and everything in the universe has its antimatter counterparts, such as antistars, antigalaxies, etc.
In addition, if a particle of matter collides with its corresponding antimatter particle, they will be annihilated and a high-energy ray will be generated.
Four years later, the theory was confirmed. The American physicist Thomas Edison discovered the first antiparticle, when he studied cosmic rays in a cloud chamber and observed the vapor trail of a particle with the same mass as an electron but with an opposite charge. This particle is named positron, which is the antimatter counterpart of the electron.
In 1955, physicists at Lawrence Berkeley National Laboratory in the United States used a particle accelerator to produce antiprotons. In the same year, scientists at the European Particle Physics Laboratory near Geneva produced positrons and antiprotons through a particle accelerator and combined them to form an antihydrogen atom, but the whole process was only a short moment.
In recent years, scientists have built sophisticated detectors to search for antimatter in cosmic rays. The antimatter detector found only a handful of positrons and antiprotons in cosmic rays, and the heavier antiparticles did not even find shadows. But scientists believe that antistars and antigalaxies are still possible to hide in the depths of the universe.

Since antimatter is the anti-state of normal matter, antimatter is not antiparticle matter, antimatter has no mass and energy, and is the opposite of mass and energy of matter, negative mass and negative energy. Antimatter is immaterial space (i.e., pure vacuum), and only pure vacuum has negative mass and negative energy.
1, The inverse of a positive number is a negative number. Negative numbers are not positive, and the magnitude of negative numbers is an indication of how much is owed.
2, The inverse length opposite to the length is the negative length. The negative length is not the length, and the amount of the negative length is the distance that is indicated.
3. The opposite area of the area is the negative area. The negative area is not the area, and the amount of the negative area is the size of the "empty area". (The empty area of the void cross-section is referred to as the empty area).
4. The anti-volume as opposed to the volume is the negative volume. Negative volume is not volume, and the amount of negative volume is the size of the volume.
5. The anti-object that is opposed to the object is a negative object. The negative object is not the object, and the number of negative objects is the magnitude of the volumetric space.
6. Antimatter as opposed to matter is negative matter. Negative matter is immaterial, and the amount of negative matter is the size of the immaterial space.

In quantum field theory, energy and momentum are strictly conserved in the reaction, and the energy e is related to the invariant mass (i.e., the static mass) m: e 2 c 2 = p 2 + m c 2, p is the momentum, this relationship is not linear, so the conservation of energy does not necessarily lead to the conservation of mass, for example, the mass of light quarks can be ignored, but the mass of neutrons and protons composed of light quarks is very large, indicating that the interaction between quarks is very strong, the energy of the interaction is very large, and this part of the energy contributes a lot to the mass of nucleons, 90% in the universe The above visible mass of the substance** is this, which is"Quality gains"As for mass loss, when protons and neutrons combine to form a nucleus, the total interaction energy between quarks is reduced, so there is less mass. e=mc*c. >>>More
