Junior High School Student Speech on Antimatter 10

For the first time ever, scientists at the European Organization for Nuclear Research (CERN) antimatter were able to capture atoms. This important breakthrough will help scientists distinguish between antimatter and normal materials. It will also allow scientists to conduct physical tests that were previously impossible.

Producing antimatter particles like positrons and antiprotons is not difficult in the lab, but mixing them to earn antimatter atoms is actually a serious challenge. Two research teams were the first to achieve this goal. These scientists proved that 10 million antiprotons and 70 million atoms of 38,118 elements formed anti-hydrogen that lasted for a second per piece.

On November 19, 2010, European scientists successfully created a number of antihydrogen atoms and made them exist for 0 17 seconds, which is a breakthrough discovery in the physics community and the first time that humans have captured antimatter. The destructive power of 500 grams of antimatter can exceed that of the world's largest hydrogen bomb.

You can start with the contradictory side.

Because antimatter and matter are like two sides of a contradiction.

Yes. After all, the matter in our surroundings is all positive matter.

Whereas, positive matter is made up of atoms – atoms are made up of positively charged protons and negatively charged electrons along with neutral neutrons.

Antimatter, on the other hand, is made up of negatively charged protons and positively charged electrons.

The hydrogen atom is currently the simplest atom with only one proton and one electron.

Then, as long as there are elements, there are atoms. Our world is always full of positively charged protons and negatively charged electrons, and once his antimatter appears, it will inevitably be annihilated.

Although, researchers have also made certain breakthroughs in this regard. However, the longest-standing anti-hydrogen atom is less than a second.

According to a report published in the British journal Nature on November 17, 2010, scientists have recently made a major breakthrough in the field of antimatter, successfully capturing antimatter to make it exist for about a second, which may seem like a short time, but it is definitely exciting for the scientific community. ”

Scientists at CERN, who are said to have succeeded in creating multiple antihydrogen atoms, used a magnetic field to keep them there for a "long time" – seconds.

CERN created the first antihydrogen atom in 1995, but it only lasted a few microseconds before it collided with positive hydrogen atoms in the surrounding environment and annihilated.

Researchers created anti-hydrogen atoms in a vacuum in 2002, but they were annihilated less than a moment after they were made.

This time, for the first time, CERN researchers have managed to "catch" this antimatter.

The reason for this prolonged existence is that in addition to using a special magnetic field to capture them (because the antiatoms are slightly magnetic), the ambient temperature is reduced to minus degrees Celsius, that is, close to absolute zero, so that the antihydrogen atoms are in a low energy state. Reaching this point is a very significant breakthrough.

Addendum: It should be necessary, otherwise you can save it as long as you use different elements to make a vacuum preservation container, but it can't be saved at the moment. It is possible that annihilation is due to the combination of protons of positive matter (positively charged) and antimatter protons (negatively charged).

The electrons of positive matter (negatively charged) and the electrons of antimatter (positively charged) are neutralized and annihilated. After all, all elements have atoms, and they are all composed of electrons and protons.

No Antimatter storage refers to a technique for storing antimatter, based on the principle that an electromagnetic field can store dark matter by keeping it away from the inner wall of the so-called "penning trap". In September 2008, Greene Air Force Base in the United States claimed to have invented a container that can effectively store antimatter for a long time, that is, it claimed to have solved the problem of antimatter storage.

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. It has not yet been manufactured, and some believe in its existence, but no convincing evidence can be found. And the question you asked, scientists don't know, they are still **, very advanced questions.

If antimatter exists, there must be a container for preservation, at least the universe is.

Antimatter is the opposite of ordinary matter (positive matter), its electrons are positive, protons are negative, and the opposite positive matter will be annihilated, producing pure energy. It's real.

On the first floor, except for the first sentence, there is nothing wrong with it.

Antimatter is not imaginary, but can exist.

Antimatter is the opposite of the nature of matter that we usually see. For example, electrons are negatively charged, but antielectrons are positively charged. Every elementary particle corresponds to a kind of antimatter, and we call our matter positive matter to distinguish it from antimatter, and you can of course call our matter antimatter and antimatter positive matter.

It's like the relationship between inside the mirror and outside the mirror.

When antimatter encounters positive matter, it will be annihilated, that is, it will all become energy and radiate out in the form of photons. But this process must be of equal mass, and 1 catty of antimatter can only annihilate 1 catty of positive matter. Therefore, a few tens of grams of antimatter cannot destroy the planet.

You may be confused with another substance, which is the miniature black hole, which can be created at the world's largest proton accelerator, LHC. However, you don't have to worry, these black holes are extremely small and have an extremely short existence, and they will not destroy the Earth.

The first floor is basically correct. But it needs to be partially supplemented.

The destruction of the planet on the first floor means the complete destruction of the entire planet. This is absolutely impossible to do with a small amount of antimatter. But the destruction that the landlord refers to should mean the destruction of the vast majority of life on the planet.

Antimatter should be the smallest amount known to humans to be able to do this.

Antimatter is difficult to produce in large quantities, so don't worry. Even if it can be produced in large quantities, storage is a problem, because antimatter is annihilated when it encounters matter, which is equivalent to putting a positive charge in a bottle made with a negative charge. I don't know if this is the right understanding, but I welcome correction.

The opposite of the positive matter, which is manifested in the distribution of electric charges, has been successfully produced in the laboratory. It's just that it's very difficult to make it at the moment.

When positive matter and antimatter meet, they will destroy each other, and 100% of them will be converted into energy, which is the maximization mode of mass-energy conversion.

Contrary only relative to our own"Positive"That's it, if there is no corresponding reference between positive and negative, then they are meaningless.

Just like light and heavy, big and small, saying that something is big or small, there needs to be a corresponding thing to compare.

For example, we often say that the earth is very large, which is generally compared to people or vehicles. If it is replaced by the sun, then the earth is "very small".

The same goes for positive matter and antimatter.

Of course, if you are more serious, the antimatter world and the positive matter world will still be different, and the positive and antimatter will not be a complete mirror image, because when the energy generates positive and antimatter pairs, there will be symmetry breaks, which leads to the fact that our universe has a little more positive matter than antimatter, so that after all the antimatter is nirvanaized by the positive matter, the remaining point is all positive matter, thus constituting the world we see.

Antimatter is mostly the same as matter, that is, the charge is opposite, and as long as it touches matter, it will be annihilated, releasing great energy. According to Einstein's mass-energy conversion equation, the energy is 100%, which is many times greater than the energy produced by nuclear fusion and nuclear fission. It's just dangerous.

However, if the antimatter pusher is successfully developed, it can fly out of the solar system with a little antimatter. However, particle accelerators around the world can only produce 3 micrograms of antimatter in a year.

Yes, you can use positive matter and annihilate it, and you can go to another world, and that's beautiful.

Against what? Anti-hydrogen atoms? Anti-helium atom?

Scientists believe that there are two symmetrical worlds in the universe – one is our positive matter world (as we define it) and another world is made up entirely of antielements, and the water in that world is anti-water – two anti-hydrogen atoms and one anti-oxygen atom will define the matter of their world as positive matter and the matter of our world as antimatter. They can't see our positive photons, we can't see their reflectors, so we can't see them, they can't see us. Everything is the opposite.

But our scientists have already made anti-hydrogen atoms. Do you know what happens if it hits a hydrogen atom? They will annihilate, emitting positive and negative photons while emitting a terrifying energy.

There is no loss of energy in this energy, it will be completely released, do you know how big this energy is? It's simply too small to describe it as an atomic bomb. According to the theory of relativity, the collision of positive and negative ions will release the maximum energy they can emit e=mc 2

m is both mass and quality. It's okay to bring it in, the unit is kilograms, (don't use the relative molecular mass, use the actual one!) If you have 500 grams of antimatter and you have 500 grams of positive matter, e=mc 2, you multiply the square of the speed of light by one, and the answer is this.

Tell me, how many atomic bombs are this number like? The hydrogen bomb is not comparable! At present, it seems that seven anti-hydrogen molecules have been collected, and it seems that they are preserved with special materials (if they are not sealed, they will kill people) There are no five hundred grams of anti-matter on the earth, as long as one anti-hydrogen atom collides with a positive hydrogen atom, it is enough to destroy the earth!

By the way, anti-world people are also afraid that our positive hydrogen atoms will collide with their anti-hydrogen atoms)

It is equivalent to the most powerful nuclear bomb available today, provided that it is completely converted into energy.
