Antmatter ina nguvu mara 1000 zaidi ya nuclia na inahitaji uangalifu wa hali ya juu zaidi sasa sijui kama tutahitaji shirika la Atomic au antmatter For other uses, see Antimatter (disambiguation).

For example, a positron (the antiparticle of the electron or e+ ) and an antiproton (p) can form an antihydrogen atom in the same way that an electron and a proton form a "normal matter" hydrogen atom. Furthermore, mixing matter and antimatter can lead to the annihilation of both, in the same way that mixing antiparticles and particles does, thus giving rise to high-energy photons (gamma rays) or other particleantiparticle pairs. The result of antimatter meeting matter is an explosion.[SUP][/SUP] There is considerable speculation as to why the observable universe is apparently composed almost entirely of matter (as opposed to a mixture of matter and antimatter), whether there exist other places that are almost entirely composed of antimatter instead, and what sorts of technology might be possible if antimatter could be harnessed. At this time, the apparent asymmetry of matter and antimatter in the visible universe is one of the greatest unsolved problems in physics. The process by which this asymmetry between particles and antiparticles developed is called baryogenesis.
