In modern physics, antimatter is defined as a material composed of the antiparticles of the corresponding particles of ordinary matter. Microscopic numbers of antiparticles are generated daily at particle accelerators and in natural processes like cosmic ray collisions and some types of radioactive decay, but only a tiny fraction of these have successfully been bound together in experiments to form anti-atoms. No macroscopic amount of antimatter has ever been assembled due to the extreme cost and difficulty of production and handling. . In theory, a particle and its anti-particle have the same mass as one another, but opposite electric chargeand other differences in quantum numbers. For example, a proton has positive charge while an antiproton has negative charge. . A collision between any particle and its anti-particle partner is known to lead to their mutual annihilation, giving rise to various proportions of intense photons , neutrinos, and sometimes less-massive particle–antiparticle pairs. Annihilation usually results in a release of energy that becomes available for heat or work. The amount of the released energy is usually proportional to the total mass of the collided matter and antimatter, in accordance with the mass–energy equivalence equation, E=mc^2. . . . . . . #physics #physists #sciencefacts #scientistlife #science #scientificmethod #scientifictheory #sciencememes #scientificresearch #photon #radiation #universe #cosmos #nightsky #galaxy #planets #space #astronomer #beautiful #stars #chandra #hubblephotography #neildegrassetyson #elonmusk #nasa #spacex #kepler #photography #hd #wallpaper https://www.instagram.com/p/BtfrliQh8ek/?utm_source=ig_tumblr_share&igshid=1jl7q2h2z2cac
