There is strong evidence that the universe is made up of almost ordinary matter, in contrast to a similar mixture of matter and matter. The asymmetry of matter and antimatter in the universe is still a major mystery in physics.  Our galaxy produces 9 trillion kilograms of antimatter a per second. But no one knows where they are in the universe.

What is Antimatter?

Simply put, an antimatter is made up of matter with negatively charged protons and positively charged electrons. But there is an Antimatter in the universe. Anti-particles have formed everywhere in the universe where high energy particle collisions occur. Remote galaxies may have relatively large amounts of antimatter due to global inflation.

In modern physics, antimatter is defined as the substance that contains antimatter particles corresponding to “normal” matter. Due to the high cost and difficulty of production and storage, making 1 gram of Antimatter is also very difficult. Also, if someone makes an antimatter artificially, it can be sold at a higher price. Antimatter is the most expensive substance in the world. The existence of the antimatter was confirmed experimentally in 1955 by the University of California, Berkeley physicists Emilio Segre and Owen Chamberlain, and in 1959 they were awarded the Nobel Prize in Physics. For the first time in the world, the CERN research institute in Switzerland was able to produce a very small amount of antimatter at a high cost.



Positrons (an antimatter species) are naturally produced by the interaction of β+ decay with naturally occurring radioactive isotopes.  Different types of living particles are also produced by cosmic rays. In January 2011, research by the American Astronomical Society discovered material (positrons) above thunderstorm clouds. Antiprotons have been discovered by the Pamela module in the Van Allen belt around the Earth. Anti-particles are also produced in any environment with a sufficiently high temperature.

Satellite experiments have shown that less than 1% of the particles in the primordial cosmic rayons contain several positrons and protiprotons. All of these antimatter cannot be created in the Big Bang, but are instead considered to be produced by cyclic processes of high energy.


In 1956, at Lawrence Berkeley National Laboratory, Barbuscock and colleagues discovered the formation of antineutrons (Antimatter species) during proton-proton collisions. Minuscule numbers of antiparticles are generated daily at particle accelerators total antimatter artificial production has been only a few nanograms.

Scientists claim that antimatter is the costliest material to make. In 2006, Gerald Smith estimated that it would cost $250 million to produce 10 milligrams of 1999, NASA gave a figure of $62.5 trillion per gram of antihydrogen (Antimatter species). This is due to the difficulty of production and the high demand for other uses of the antimatter. According to CERN, it has cost a few hundred million Swiss francs to produce about 1 billionth of a gram (the amount used so far for particle/antiparticle collisions).
