MYSTERIOUS MATTER IN COSMOS : ANTI-MATTER

In 1939, one of the great scientists and physicists the world has ever seen, Richard Feynman, proposed that the entire universe is made up of a single anti-electron & electron that travels back and forth in time, respectively (electron-positron symmetry). From there, the story of anti-electron (matter) starts.

The problem with anti-electron is that if it comes with the contact of matter, it emits high energy radiation; the amount of energy released is usually proportional to the total mass of the collided matter and anti-matter mass-energy equivalence equation, E=mc².

Many scientists think that when this universe was created, there was an equal amount of matter, and anti-matter was produced, but why did they not collide within billions of years, and if not, then where has all the anti-matter gone?

In addition, scientists also state that matter comprises just 4.9% of the universe, dark matter (mysterious matter that can only be felt by gravity pulls on other objects) makes up 26.8%. Dark energy is composed of 68.3%. We can see dark matter and dark energy everywhere in the universe, but there is no sign of anti-matter.

In Geneva, the European Organization for Nuclear Research (CERN) created the first antiatom, the anti-matter, consisting of a positron in orbit around an antiproton nucleus.

From human observation, it can be said that anti-matter does not really exist except for when it is created by specialized places like the CERN and that too for a temporary period, or when it is rarely produced in some high-energy instances like cosmic rays.

Some scientists believe that the "missing" anti-matter does exist, and it forms antigalaxies made from antistars and antiplanets, which we have not observed yet.
