One gram of antimatter is worth $62.5 trillion. What kind of matter is in the universe?
The the most expensive thing in the world
is both dangerous and destructive. It can destroy the world at the slightest point, and the thrusters made of it can make a qualitative leap. Annihilation and the Big Bang, this is what antimatter looks like in the minds of most people, or in the early days, antimatter was once a god due to various transmissions. Antimatter does hold a lot of energy, but it's not as exaggerated as we think. By comparison, it's the price that's really surprising. At present, the price of a gram of antimatter is about 62.5 trillion US dollars, which is by far the most expensive material on earth. The reason antimatter is so expensive is that it is almost impossible to "catch" in nature, and unlike other man-made matter, the purpose and science of antimatter's capture greatly increases its production cost. So. What is antimatter? The Toroidal Instrument, used to observe high-energy particles In modern physics, antimatter is defined as matter consisting of the antiparticles of the corresponding particles in "ordinary" matter. Particle accelerators, for example, produce tiny amounts of antiparticles every day, with a total artificial output of only a few nanograms. In the universe, antimatter is also produced in natural processes such as cosmic ray collisions and certain types of radioactive decay. So from this perspective, antimatter is not a concept limited to matter itself. Only a small fraction of the many antiparticles can be successfully bound in experiments to form antiatoms. Due to the extremely high production cost and processing difficulty, humans have never achieved a macroscopic amount of antimatter so far. Positrons observed in Wilson's cloud chamber Now we all know that the basic particles that make up matter are protons, electrons and neutrons. In 1930, British physicist Paul Dirac also proposed a similar description of electrons, he predicted Antiparticles without electrons should exist. At the time he wrote an equation that combined quantum theory and special relativity to describe the behavior of electrons moving at relativistic speeds. This equation, which later earned him the Nobel Prize in 1933, explained it as for every particle there is a corresponding antiparticle that exactly matches that particle, but with opposite charges. British physicist Paul Dirac later discovered that other fundamental atomic particles also have antimatter counterparts, namely antiprotons and antineutrons. Annihilation occurs when a particle and its antimatter counterpart meet. This means that the two particles disappear and their masses change according to Einstein's famous equation of mass-energy equivalence. This means that even a small amount of mass can be converted into a large amount of energy, the scientists analyzed computationally. The energy produced by antimatter in the annihilation process is 10,000,000,000,000 times more powerful than a chemical explosion such as trinitrotoluene, and 10,000 times more powerful than a nuclear bomb explosion. This may be the deepest impression that antimatter has left on people's minds. Of course, antimatter is far more than these functions. Antimatter bombs would have no problem destroying EarthScientific research has shown that the observable universe is made almost entirely of ordinary matter, rather than an equal mixture of matter and antimatter. Likewise, most matter observed from Earth appears to be composed of matter rather than antimatter. If only antimatter-dominated regions of space could exist, then gamma rays from annihilation reactions along the boundary between matter and antimatter regions should be detectable. As we said earlier, wherever energetic particle collisions in the universe are, it produces antiparticles. The high-energy cosmic rays that strike Earth's atmosphere or any other matter in the solar system produce particle jets that also produce trace amounts of antiparticles. The eight parts of the toroid instrument, but these antiparticles exist for a very short time, and the antiparticles will immediately annihilate when they come into contact with nearby matter. For astronomers, antiparticle activity can reflect the time of high-energy celestial bodies existing in the universe, mainly in two aspects: relativistic jets and interstellar medium. The European Space Agency's observations of the galactic center using the Gamma-ray Astrophysics Experiment satellite could explain the origin of the giant antimatter cloud that surrounds the center of the Milky Way. The observations show that the clouds are not aligned, and the patterns of the X-ray binaries match each other. When it's mostly on one side of the Milky Way's center, the antimatter cloud picks up the kinetic energy left behind by the stellar remnants. The nebula shown by the Hubble telescope is not impossible to create antimatter in an artificial environment. In order to create real antimatter, scientists focus on the simplest form of matter, hydrogen. The composition of the hydrogen atom is very simple, consisting of only one electron and one proton, which means that its antimatter will be equally simple. Antihydrogen consists of antiprotons and positrons, which are attracted by the antiprotons. The world's first antihydrogen was created at CERN in 1995. Scientists used a supercollider to create it by colliding antiprotons and xenon atoms. The device Alpha Labs uses to capture antihydrogen This collision produces a positron, which is electrically attracted to another antiproton, forming antihydrogen. But unfortunately, the existence of antimatter particles is very short, the annihilation process is very fast, and then the energy is released, and it will disappear in a few millionths of a second. Because of this, scientists have been looking for a way to stabilize antimatter particles. The key to retaining antiparticles is to slow down antiparticles to prevent them from colliding. In theory, antimatter can be stored in a bottle half a degree higher than absolute zero, thereby realizing antimatter preservation. The machine used to produce low-energy antiprotons has retained antihydrogen for 15 minutes in this way as of 2011. It is worth mentioning that antimatter is not as mysterious as we think, it also exists in our life. Although no stable antimatter exists in nature, there are some sources of antimatter. For example, the bananas we usually eat, they also release antimatter. Bananas release a positron, the antimatter equivalent of one electron, about every 75 minutes. "Don't worry, bananas won't explode" This is because bananas contain a small amount of potassium-40, which acts as an isotope of potassium, and as potassium-40 decays, bananas release a positron in the process. In addition, there is potassium 40 in the human body, but why do people not produce annihilation or a large amount of energy release? In fact, although humans can emit positrons, they produce very little antimatter by themselves. If all the antimatter released in one's lifetime were to be annihilated, it would not produce enough energy to heat a glass of water. Antimatter is everywhere The reason antimatter is so expensive today is that, in addition to the cumbersome creation of it, it is also very difficult to preserve, even in a tiny amount. In theory, it would take about 25 million kilowatt-hours of energy to make 1 gram of antimatter, and that would cost $10 billion. For example, the particle accelerator in Fermilab, all the antiprotons it produces add up to only 15 nanograms, and some large underground particle research laboratories in Europe are even less, and the antimatter they produce weighs only 1 nanometer gram. CERN's Antimatter Trap According to CERN, antimatter requires hundreds of millions of grams of energy to make just one billionth of a gram, and the cost of making antimatter looks like $62.5 trillion per gram. In addition to scientific uses, antimatter has very broad prospects for future applications. In medicine, antimatter can help medical devices perform medical imaging. Such as Positron Emission Tomography, or PET for short. Through beta decay, the nuclide emits a positron causing itself to lose its excess positive charge. Antimatter can be used in medicine Nuclides with excess positive charge can be easily fabricated in cyclotrons and are widely used in medicine. At present, the medical community has proved that antimatter therapy has certain medical potential in the treatment of certain cancers. Of course, the most exciting part is interstellar travel. Through the energy emission caused by the collision of matter and antimatter, the entire rest mass of the particle will be converted into kinetic energy. The energy per unit mass is about 10 orders of magnitude greater than chemical energy, while the nuclear energy used today is only 3 orders of magnitude larger. The imaginary antimatter rocket science has calculated and analyzed that if an antimatter rocket can be made, it can reach about 72% of the speed of light. But not all annihilation energies lead to improvements in propulsion technology. Also in the reaction between protons and antiprotons, their energies decay into high-energy photons immediately. Gamma-ray photons generated by the reaction of electrons and positrons are difficult to guide for propulsion, and current research is still in theoretical exploration. Annihilation or creation, this is the thinking that antimatter will bring to scientists.
