In particle physics, anti-mass is material composed of antiparticles, which have the same mass as subatomic particles of ordinary matter but have opposite electric charge and quantum spin.Is is also known as Anti Matter.See Antimatter.Antimass - a mirror image of matter - is an idea so revolutionary that even its discoverer initially feared its consequences. It annihilates with ordinary matter, disappearing in a puff of energy - the ultimate scientific experiment.The end result of antimatter meeting matter is a release of energy proportional to the mass as the mass-energy equivalence equation, E =' 'mc'' 2 shows.

History
The history of antimass begins in 1928 with a young physicist named Paul Dirac and a strange mathematical equation...

The equation, in some way, predicted the existence of an anti world identical to ours but made out of antimatter. From 1930, the search For the possible constituents of antimatter, antiparticles, began, and it has been the main influence behind a major scientific and technical evolution over the last 70 years.

Production
They exist as naturally and can also be produced artificially.

Natural existence Positrons are produced naturally in β+ decays of naturally occurring radioactive isotopes (for example, potassium-40) and in interactions of gamma quanta (emitted by radioactive nuclei) with matter. Antineutrinos are another kind of antiparticle created by natural radioactivity (β− decay). Many different kinds of antiparticles are also produced by (and contained in) cosmic rays. Recent (as of January 2011) research by the American Astronomical Society has discovered antimatter (positrons) originating above thunderstorm clouds; positrons are produced in gamma-ray flashes created by electrons accelerated by strong electric fields in the clouds.

Artificial production- Antimass are also produced in any environment with a sufficiently high temperature (mean particle energy greater than the pair production threshold). During the period of baryogenesis, when the universe was extremely hot and dense, matter and antimatter were continually produced and annihilated. The presence of remaining matter, and absence of detectable remaining antimatter.

Positrons can also be produced by radioactive [[beta+ decay]], but this mechanism can occur both naturally and artificially.

Uses
It is generally used for energy production.Now antimatter is used every day in medicine for brain scans. Transforming all its mass into pure energy, antimass is the perfect fuel. Star Trek's faster-than-light science-fiction spaceships use antimatter power, but research projects have also investigated the use of antimatter fuel for real.
