The effects of antimatter November 15, 2010, the UK reported the presence of antimatter for 0 17 se

After the universe is large, a huge amount of energy is released, and this energy is matter, that is, particles, there are positive particles and antiparticles, they collide with each other, but the uncertainty principle of quantum theory shows that there is no such thing as perfection in the universe, so C (positive and negative particle reversal) P (take the mirror image) T (take the time inversion, that is, the point to the direction of motion) joint symmetry is established, and the microscopic scale cp joint symmetry does not hold, that is, T symmetry fails, so that the antiparticle can become a positive particle in a high-energy environment, The opposite process is also allowed, but the laws of physics are not exactly the same for positive particles and antiparticles, so a small number of particles remain after the positive and negative particles are extinguished, and we can never even figure out whether the residual particles are positive particles or antiparticles (if the residual particles are antiparticles, we can just reverse the name, this is just a man-made name), these residual positive particles are also positive matter with positive energy to form galaxies and ourselves, In the absence of human interference, only antimatter existed at the beginning of the universe (with the exception of black holes). With the development of science, human beings' curiosity about the elementary particles of all things is becoming more and more intense, so generations of high-energy particle colliders continue to accelerate the proton beam to collide in order to be able to see smaller (because the higher the energy, the smaller we can detect), and at the same time, the high enough energy can simulate the microscopic approximate environment of the universe, which is the positive particles under high energy to become antiparticles, that is, antimatter, but once the antimatter comes into contact with the positive energy of the positive matter, it will immediately cancel out with the positive energy. There is no way to capture at will, there is no way and clue to solve this problem at present, which will also be the biggest technical barrier to the realization of space-time in the future, if there can be a continuous negative energy area and enough space-time curl, you can shuttle in three-dimensional time (light will deflect when passing through a large energy (mass) object, which proves that space can be curled as long as the energy is large enough). Black holes are the most bizarre phenomenon in nature, and the huge energy generated by black holes makes all the laws of physics collapse the moment they reach the singularity, so everything is possible there, including, of course, antimatter.

The conclusion is that antimatter has existed in black holes (only theoretically), but that the current form of human thought has no hope of accessing and exploiting them, even though they are so attractive and have high application value.

The previous one is not right, antimatter is actually the same as matter, that is, the particles are charged in the opposite direction, and the annihilation of the same amount of matter and antimatter produces 2mc 2 energy.

Antimatter is both angels and demons.

Angel: It can become a new energy source, and the energy is not known how many times the energy of nuclear energy.

Let's put it practically, antimatter the size of a button would allow the space shuttle to do a few interstellar trips.

Devil: Can become a new **, the power is 1 gram is enough to destroy the earth.

Let's be practical, a few micrograms of antimatter and the energy emitted by the annihilation of matter is equivalent to an atomic bomb, and I recommend you to watch the movie "Angels and Demons".

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."

And positive matter will produce annihilation to release a large amount of energy, which can be done **, exterminate the little Japanese and Southeast Asian monkeys, Indian Ah San ......Students, this great cause of the party-state will be handed over to your generation......

Antimatter is a class of matter that is composed of particles of the same mass and opposite charge as the particles we see every day.

Antimatter was originally predicted to exist by physicists, and it seems to have been in the last century.

In the twenties and thirties, experiments confirmed its existence.

It has now been proven that all particles have corresponding antiparticles, such as antiprotons, which have the same mass as protons, but they carry a negative charge; The antielectron, which has the same mass as the electron, but it carries a positive charge, so it is also called positron. When a positron meets an antiproton, it can also form an atom, which is also a hydrogen atom, but it can only be called antihydrogen. When positive and negative particles of the same kind meet, such as positive and negative electrons meet, or positive and negative protons meet, annihilation will occur, and the particles will cease to exist and will only be converted into energy.

Some particles' antiparticles are themselves, for example, neutron antiparticles are still neutrons, and photon antiparticles are photons.

Antimatter is a substance whose charge is opposite to that of positive matter, for example, in positive matter, the electric pole of the proton is the positive electrode, and the charge of the electron is the negative electrode. Whereas, in antimatter, the electrode of the proton is the negative electrode and the charge of the electron is the positive electrode. However, once antimatter is generated, it is easy to annihilate with the surrounding matter and become complete energy.

Thank you for the trouble to adopt!

Because the mass of matter and antimatter can be completely converted into energy when it is annihilated, bringing the greatest energy efficiency, and the unit output is thousands of times that of nuclear energy or hundreds of trillions of conventional fuels, so it has been studied as a new energy source, mainly used for aerospace applications that are difficult to replenish fuel, and even as antimatter**. However, due to the current artificial way of creating antimatter, it is synthesized by accelerating particles hitting a fixed target to produce antiparticles, and then decelerating. The energy required for this process is much greater than the energy emitted by annihilation, and the rate at which antimatter is generated is extremely low, so it has no economic value.

In addition, annihilation occurs when antimatter meets matter, and preservation is also a major problem.

Philosophically, this question is easy to answer. The ancient Taiji diagram in China also seems to imply its existence, and some astronomers also believe that it is possible, but modern astronomy has not yet come up with convincing evidence. There are many people who deny antimatter, says the American cosmologist Schramm

Most theorists intuitively believe that antimatter does not exist. This means that if you find it, it's a great discovery that proves these theorists wrong. But most likely, it means you can't find it.

So far, scientists from 16 countries have participated in the study, led by Ding Zhaozhong, and more than $100 billion has been invested. Many scientists say that as long as the existence of cosmic antimatter can be discovered, then it will be a well-deserved Nobel Prize.

The probe was launched in 2005 and remains in space permanently, and Southeast University will also establish a data reception and analysis center and a training center as supporting projects. Ding Zhaozhong believes that if antimatter does exist, a huge amount of energy can be generated when positive matter collides with antimatter. He is currently leading the research on "Searching for Dark Matter and Antimatter in the Universe" for many years, and has achieved some important results.

However, judging from the history of the development of this field, people should be mentally prepared that we may find something unexpected that has nothing to do with what we originally wanted to study. Ding Zhaozhong said very cautiously. Starting from Laplace's great prophecy, German scientists believe that black holes tear apart stars to produce antimatter Celestial bodies have a huge gravitational pull, and under the action of huge gravity, various reactions will occur and glow and heat up.

The extremes of things must be reversed, Laplace (p?s?laplace) once boldly prophesied:

The largest celestial bodies in the universe may be invisible. When gravity increases with mass, the celestial body becomes a region of nothing, neither heating nor emitting light, which is now called a "black hole". Therefore, the universe is more composed of invisible dark matter or antimatter, and all we can "see" with the naked eye and astronomical instruments is the structure of the universe in the form of stars or galaxies, which only accounts for 10 of the total universe, and 90% of the matter exists in the form of dark matter or other structures.

Obviously, the presence of a huge gravitational pull on visible matter indicates the existence of dark matter or antimatter. But we can't detect them with light, and we can't detect them with infrared, ultraviolet and X-rays. In the same way, is there an anti-cosmic structure system corresponding to the existing galaxy structure system?

In fact, as early as 1898, a British physicist proposed that like the existence of matter, there is a mirror image corresponding to the existence of antimatter. Due to the scientific level and experimental conditions at that time, this concept of antimatter had no factual basis, so the existence of a cosmic stellar cloud composed of antimatter in the depths of the universe can only be a hypothesis in the pure sense.

What is antimatter and does it really exist?

Antihydrogen atoms are theoretical antimatter that can be artificially created at present, but they are still far from the practical meaning of antimatter that scientists are seeking. The book presents a lot of esoteric and obscure physical theories and knowledge in simple and popular language, even if you are a layman who has never been exposed to atomic and quantum theory, you can form a preliminary understanding of the above concepts in your mind through this book. Before we can understand antimatter, we need to understand matter.

The so-called matter is omnipresent to us, and the space we humans live in is made of matter. The food we eat, the clothes we wear, and the tools we use are visible substances; X-rays from hospitals, the air that fills the air, and time are invisible substances. Matter is made up of molecules, molecules are made up of atoms, atoms are made up of nuclei and charged electrons, the nucleus is made up of protons and neutrons, and the internal structure of protons and neutrons is quarks.

Antimatter is like the shadow of matter reflected in a mirror, they may look like twins on the outside, but they are structured in completely opposite ways on the inside. When matter and its antimatter meet, a complete matter-to-energy conversion occurs, resulting in maximum energy efficiency and a unit yield of hundreds of times that of nuclear energy or trillions of times that of conventional fuels. In addition, cosmologists speculate that there may be hiding places for antimatter in the "black holes" of the universe with masses exceeding the limit.

In addition, the book also introduces many famous physicists and scientific research and development institutions in the 20th century, and it is not an exaggeration to regard it as a miniature history of the development of physics in the 20th century.

At present, China can only use short-range laser technology to produce a small amount of antimatter, and cannot produce antimatter bombs. Because antimatter is very difficult to preserve. It's like a flash in the pan.

However, antimatter research is necessary, but antimatter bombs should not be made, antimatter energy can be used as fuel for interstellar spacecraft, so that the speed of spacecraft can reach 70% of the speed of light, China is currently the most powerful country in the field of antimatter research in the world.

There is no country, you can rest assured, because the reason is very simple, if a country has this fantasy **, it will definitely not hide it, it will have been used to conquer the earth a long time ago, and you will not be able to ask these ridiculous questions in front of your computer without incident.

You have to figure out what antimatter is before you can determine what antimatter is. Before determining what antimatter is, there is antimatter**, and it will not be recognized by everyone.

<> antihydrogen atom is the opposite of a hydrogen atom, which has a positively charged proton inside the nucleus and a negatively charged electron on the periphery, while the antihydrogen atom is the opposite.
