Yog tias thaj chaw tiv thaiv tsis muaj teeb meem ntawm qhov chaw muaj, gamma rays uas tsim tawm hauv kev cuam tshuam kev puas tsuaj raws tus ciam teb ntawm thaj chaw teeb meem thiab thaj chaw antimatter yuav ntes tau. … Lub xub ntiag ntawm qhov tshwm sim antimatter yog kuaj pom los ntawm ob lub gamma rays tsim txhua zaus positrons rhuav tshem nrog cov teeb meem nyob ze.
Yuav ua li cas cov tshuaj tiv thaiv raug tsim?
Particle thiab antiparticle khub yog tsim los ntawm cov khoom loj ntawm lub zog … Hloov pauv, thaum cov khoom sib ntsib nrog cov tshuaj tiv thaiv, lawv rhuav tshem mus rau hauv qhov tawg ntawm lub zog. Thaum lub sij hawm ntawm qhov loj bang, lub siab zog ceev ntawm lub ntug yuav tsum tau tsim ib tug sib npaug npaum li cas ntawm hais thiab antiparticles.
Peb puas tuaj yeem pom cov tshuaj tiv thaiv hauv ntiaj teb?
Tus antimatter ploj lawm - tsis yog los ntawm CERN, tab sis los ntawm Lub Ntiaj Teb! Tsawg kawg yog qhov peb tuaj yeem txiav txim siab kom deb li deb ntawm kev ua tib zoo tshuaj xyuas cov pov thawj. Rau txhua qhov tseem ceeb ntawm cov teeb meem, muaj ib qho antiparticle nrog tib lub zog, tab sis tus nqi hluav taws xob rov qab.
Paul Dirac nrhiav tau cov tshuaj tiv thaiv li cas?
Paul Dirac xyoo 1928. … Tsuas yog ob peb xyoos tom qab ntawd, kev soj ntsuam ntawm cosmic rays nyob rau hauv cov huab cua sab saud nrhiav pom thawj cov tshuaj tiv thaiv kab mob, lees paub Dirac qhov kev xav. Nws tau qhia tias kev sib txheeb thiab quantum mechanics tuaj yeem ua ke tom qab tag nrho, tsim kom muaj ib ceg tshiab ntawm physics: quantum field theory.
Vim li cas antimatter thiaj kim?
Vim nws qhov xwm txheej tawg (nws rhuav tshem thaum sib cuag nrog cov teeb meem ib txwm muaj) thiab cov khoom siv hluav taws xob ntau, tus nqi ntawm kev ua cov tshuaj tiv thaiv yog hnub qub. CERN tsim tawm txog 1x10^15 antiprotons txhua xyoo, tab sis qhov ntawd tsuas yog 1.67 nanograms.
