Antimatter

Antimatter is a very strange concept in physics. Antimatter consists of anti particles that have the same size and mass as their corresponding ‘regular matter’ but opposite charge. For instance a positron is the size of an electron but contains a positive charge. The current theory for the universe, the Big Bang Theory, predicts that an equal amount of matter and anti matter were present at the beginning of the universe. But today, anti matter occupies a negligible amount of the universe’s composure. So physicists have been stumped as to where all the antimatter has gone. Probably the biggest issue with studying antimatter is the fact that antimatter tends to be destroyed and converted to energy a very short time after its creation, because if a particle and its corresponding anti particle collide, the two particles will annihilate and be converted to energy. This poses a problem to physicists as any anti matter created artificially or naturally will very quickly annihilate preventing physicists from studying them. Moments after the big bang, matter and anti-matter were continually colliding and annihilate and then reforming from the energy released. How the universe has become dominated by antimatter is one of science greatest unanswered questions. Antimatter tends to form nuclear decay of atoms, the antimatter then annihilates, producing gamma rays. This is how we know that portions of the universe aren’t ‘dominated’ by anti matter because large amounts of gamma rays would be produced where the matter and antimatter sections intersect.
