Tsis muaj tus lej macroscopic ntawm cov tshuaj tiv thaiv puas tau sib sau ua ke vim yog tus nqi siab thiab nyuaj ntawm kev tsim khoom thiab tuav. Raws li txoj cai, ib qho particle thiab nws cov anti-particle (piv txwv li, ib tug proton thiab ib tug antiproton) muaj tib lub loj, tab sis opposite hluav taws xob nqi, thiab lwm yam sib txawv nyob rau hauv quantum tooj.
Puas muaj tshuaj tiv thaiv kab mob?
Antimatter detectives
Rau txhua qhov tseem ceeb ntawm qhov teeb meem, muaj ib qho tshuaj tiv thaiv nrog tib pawg, tab sis qhov hluav taws xob rov qab. Piv txwv li, cov hluav taws xob tsis zoo, muaj cov tshuaj tiv thaiv zoo hu ua positron.
tib neeg puas muaj tshuaj tiv thaiv?
Tib neeg tau tsim ib qho me me ntawm cov tshuaj tiv thaiv xwb . Cov tshuaj tiv thaiv tsis zoo muaj peev xwm tso tawm ntau lub zog. … Txawm li cas los xij, tib neeg tau tsim ib qho me me ntawm cov tshuaj tiv thaiv. Tag nrho cov antiprotons tsim ntawm Fermilab's Tevatron particle accelerator ntxiv txog li 15 nanograms.
Pob antineutrinos muaj nyob?
Antieutrinos. Rau txhua tus neutrino, tseem muaj cov tshuaj tiv thaiv sib raug, hu ua antineutrino, uas tseem tsis muaj hluav taws xob thiab ib nrab-tus lej tig. Lawv txawv ntawm cov neutrinos los ntawm kev muaj cov cim qhia ntawm tus lej lepton thiab cov chirality opposite (thiab yog li ntawd rov qab-kos npe tsis muaj zog isospin).
Yuav nrhiav tau dab tsi nyob qhov twg?
Hnub no, cov tshuaj tiv thaiv feem ntau pom hauvcosmic rays – extraterrestrial high-zog particles uas tsim cov khoom tshiab thaum lawv zip rau hauv lub ntiaj teb cua.
