Physics | The Mysteries of Antimatter
Δημοσιεύτηκε στις 13 Αυγ 2017
In
particle physics, antimatter is a material composed of the antiparticle
"partners" to the corresponding particles of ordinary matter. A
particle and its antiparticle have the same mass as one another, but
opposite electric charge and other quantum numbers. For example, a
proton has positive charge while an antiproton has negative charge. A
collision between any particle and its antiparticle partner leads to
their mutual annihilation, giving rise to various proportions of intense
photons (gamma rays), neutrinos, and sometimes less-massive
particle–antiparticle pairs. The consequence of annihilation is a
release of energy available for heat or work, proportional to the total
matter and antimatter mass, in accord with the mass–energy equivalence
equation, E = mc2.
