What is Antimatter? How many times more energy can it produce than nuclear energy in the same volume

Antimatter is an imaginary form of matter, and in particle physics, antimatter is an extension of the concept of antiparticles, which are made up of antiparticles, just as ordinary matter is made of ordinary particles. The combination of matter and antimatter is like the combination of particles and antiparticles, causing both to annihilate and thus emitting high-energy photons or gamma rays. In 1932, the American physicist Carl Anderson experimentally confirmed the existence of positrons.

Subsequently, negative protons and antineutrons with opposite spin directions were discovered.

It should be noted that particles are not specific substances that actually exist such as neutrons and protons, but they are collectively referred to as a model concept. For example, there are lions, tigers, etc., but there is no such thing as "animal", so the word "animal" is a general term, and the same is true for "particles".

In layman's terms: antimatter is an imaginary universe with an initial 0Then any positive number that occurs after that will have a corresponding negative number will appear ......In the same way, any of our entities has a corresponding opposite substance appearing ......

Matter made up of antiparticles. There is a quantum number between an antiparticle and a particle that is opposite, usually electrically opposite, but there are many cases where the baryon number is reversed.

Antimatter and matter together will annihilate into photons, but this is not absolute, antimatter and matter can also exist at the same time, a bit like a Taiji diagram. For example, when positrons and electrons are together, they can form electron couples, which you can understand as they are spinning, just like the nucleus of an atom and an electron.

Antimatter and material annihilation are also a manifestation of nuclear energy. The equation that they all obey together is δe=δmc.

Because the amount of energy generated is only related to the energy lost.

Antimatter is generally very small, so nuclear fusion is produced more.

Antimatter is the most powerful source of energy known to mankind. It releases energy with 100% efficiency (the chance of nuclear fission is 1.5 percent). Antimatter does not pollute and does not produce radiation, and a small drop of antimatter can sustain the kinetic energy of the entire New York City throughout the day, and antimatter is extremely unstable, and it can turn anything it comes into contact with ...... ashesEven the air is no exception.

Just one gram of antimatter is equivalent to the energy of a 200,000-ton nuclear bomb - more than 2,000 times stronger than the atomic bomb dropped on Hiroshima when matter comes into contact with antimatter, the outermost electrons of the atom cancel out because of the opposite charge, the protons in the nucleus cancel each other out for the same reason, and the antineutron collides with the neutron because of its magnetic opposite, and the neutron emits an amazing energy. Albert Einstein calculated this complete rate of energy release, compared to which nuclear fission is as insignificant as striking a safety match.

However, the researchers captured 38 antihydrogen atoms for the first time, with a duration of one-fifth of a second. That's not enough antimatter to make a 100-watt light bulb glow two billionths of a second, let alone use it as a violent explosive.

Antimatter has a lot of energy.

First, according to Einstein's mass-energy equation: e = m c c, e is energy, c is the speed of light, constant.

The energy produced is: e= m c c.

Then look at nuclear fusion: if H atom fuses into H atom, the changing mass is: m1

Antimatter is annihilated with positive matter and the changing mass is m2

Obviously, m2 is much larger than m1. Because: m2 is the total mass of the atom is converted, and : m1 is only a very small part.

So: In e, the energy of antimatter annihilation is far greater than that of nuclear fusion.

However, the point is that antimatter only exists in laboratories on Earth, and very little. Because once antimatter exists, it is immediately annihilated by the atoms in the air on the earth, or the atoms in the container. If you can't gather in large quantities, you can't burst out of energy.

So, I don't think it's possible to use antimatter as a ** on Earth. But in space, the addition of a magnetic field as a "container", the high vacuum of outer space can provide space for antimatter to exist.

But if it is **, when it enters the earth's atmosphere, it will immediately be annihilated with the air, so it is not realistic to be **.

Antimatter annihilation converts all mass into energy, while nuclear reactions only turn lost mass into energy, so the two are much more energetic than antimatter reactions.

Large antimatter It is said that less than one gram can produce 484 tons of TNT explosives.

Antimatter produces a large amount of energy, antimatter can release energy of 100, while nuclear fission is only 15% antimatter does not exist on the earth, it is ** in the depths of the universe, it is difficult to preserve, and it will be annihilated when it encounters ordinary matter, so it cannot be used as **.

It must be that the energy produced when the positive and antimatter are annihilated is large.

If you use it as **, there is a problem first, how to preserve antimatter, and the antimatter will be annihilated when it encounters positive matter.

If it's the same amount, it's definitely antimatter that produces a lot of energy.

But antimatter should not be able to do it now. It's gone before I put it in = =

Question 12 a. There is a loss [at this time, it is no longer the conservation of mass, but it should only be conserved].

Question 13 b. False [There are no archaeological findings to support the idea of "making traps to hunt large animals"].

Question 14 b. Wrong [The winding direction of the plant's winding stem is basically accidental].

The 17th Beijing Primary and Secondary School Students' Natural Science Knowledge Competition. [Crowd: Are you swollen Yoshishima drop?!] Me: I also have to answer the question

Energy is just a change in the state in which energy is stored.

If it's an equal amount.

It must be that antimatter produces a lot of energy.

But antimatter should not be able to do it now. It's gone before I put it in = =

I understand and think that antimatter has a lot of energy, because first of all, there is a basis, according to Einstein's mass-energy equation e m c, e is energy, c is the speed of light, and the energy produced by a constant is e m c, and then look at nuclear fusion, if h atoms are fused into he atoms, the mass of change is, m1 antimatter and positive matter are annihilated, and the mass of change is obviously m2, m2 is much larger than m1, because m2 is completely converted by atomic mass, and m1 is only a small part.

So in e, the energy of antimatter annihilation is much greater than that of nuclear fusion. The point, however, is that antimatter is only found in labs on Earth and is rare. Because as soon as antimatter exists, it is immediately annihilated by atoms in the air or containers on Earth, it cannot gather in large quantities and therefore cannot burst out of energy.

Therefore, I think that the use of antimatter as ** on Earth is unlikely, however, in space, magnetic fields are added as containers.

The high vacuum of outer space can provide space for the existence of antimatter, but if it is a kind of **, when it enters the earth's atmosphere, it will be immediately annihilated by the air, so it is unrealistic as a **, in the very popular movie "The Wandering Earth" describes that the future human beings are facing the crisis of the sun turning into a red giant. In order to prevent the earth from being swallowed up by the gradually expanding sun, mankind launched the Wandering Earth project.

With the joint efforts of all mankind, they have installed thousands of planetary engines on the sunny side of the earth, and it is through these engines that the earth can gradually move away from the sun, although some experts point out that there are many unscientific things in this movie, but the possibility of the sun becoming a red giant and swallowing the earth is still in the movie, which is actually what mankind may worry about in the future.

As for the question of which energy is greater than antimatter energy or nuclear energy, and how to understand it, I will explain it here today.

Because the conversion of matter into energy will produce other substances at the same time, therefore, only energy cannot appear matter, and it needs the support of other substances and the action of energy to form matter.

According to Einstein's mass-energy equation, it only shows that an object has two sides of energy and mass, and it exists equivalently, but it cannot be directly changed into matter, and there is no such condition.

Matter will be turned into energy through nuclear reactions, and if you want to turn energy into matter, you will definitely need some conditions, but these conditions have not yet been reached.

Matter is converted into energy through nuclear reactions, which is in accordance with the law of conservation of energy, whereas energy is not converted into matter because it does not conform to the law of conservation of energy. needed. The conditions are also very complex.

Matter can be transformed into energy, but energy cannot be turned into matter, because energy is only a form, and matter is real, not possible.
