Nyob hauv qab no, kuv yuav sib cav (raws li Feynman) tias ob qho xwm txheej yuav tsum muaj rau cov tshuaj tiv thaiv kom muaj nyob hauv Xwm: thawj yog tias lub zog ntawm ib qho khoom ib txwm zoo, thiab qhov thib ob yog qhov xwm txheej ua raws li cov hauv paus ntsiab lus ntawm kev sib txheeb.
Lub hom phiaj ntawm kev tawm tsam yog dab tsi?
Antimatter yog siv tshuaj . Cov no tau txhaj rau hauv cov hlab ntsha, qhov chaw uas lawv tau tawg lawm, tso cov positrons uas ntsib cov electrons hauv lub cev thiab rhuav tshem.. Cov kev puas tsuaj tsim gamma rays uas yog siv los tsim cov duab.
Vim li cas peb thiaj muaj tshuaj tiv thaiv?
Antiparticles yog tsim nyob txhua qhov chaw hauv lub qab ntuj khwb qhov chaw muaj zog particle sib tsoo. … Antimatter tej zaum yuav muaj nyob rau hauv cov loj heev nyob deb galaxies vim cosmic inflation nyob rau hauv lub primordial lub sij hawm ntawm lub ntug.
Vim li cas cov tshuaj tiv thaiv tsim?
Thaum lub zog txaus yog nyem rau hauv qhov chaw me me, xws li thaum lub sij hawm muaj zog sib tsoo ntawm CERN, particle-antiparticle khub yog tsim los ntawm tus kheej. … Thaum lub zog hloov mus rau hauv pawg, ob qho tib si teeb meem thiab cov tshuaj tiv thaiv raug tsim los sib npaug.
Vim li cas positrons muaj?
Qee cov positrons yog tsim los ntawm ib hom tsis tshua muaj radioactive decays, beta-plus decays. Lub positron yog tsim ua ke nrog ib qho tsis pom neutrino-electron uas khiav tawm kom pom. Lub zog yog muab los ntawm lub zog tso rau hauv kev lwj.

Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv thiab tshuaj tiv thaiv?
Raws li nouns qhov txawv ntawm antitype thiab hom yog hais tias antitype yog ib yam dab tsi uas yog cim los yog sawv cev los ntawm ib homthaum hom yog ib pab pawg raws li cov yam ntxwv sib koom; ib hoob . Antitype txhais li cas? 1a:
Cov tshuaj tiv thaiv puas tiv thaiv kab mob?
Cov ntaub ntawv tshiab kawg qhia tau tias kev txhaj tshuaj tsis yog tiv thaiv tib neeg cov tshuaj tiv thaiv xwb, nws txo qis txoj hauv kev uas lawv tuaj yeem kis tus kabmob mus rau lwm tus. Cov tshuaj tiv thaiv COVID-19 puas tiv thaiv kev sib kis?
Cov tshuaj tiv thaiv puas muaj txiaj ntsig tiv thaiv delta variant?
Cov tshuaj tiv thaiv Delta muaj txiaj ntsig zoo li cas ntawm cov tshuaj tiv thaiv COVID-19? Hais txog Delta Variant: Cov tshuaj tiv thaiv muaj txiaj ntsig zoo rau kev mob hnyav, tab sis Delta variant ua rau ntau dua Kev kis kab mob thiab kis tau sai dua li cov qauv ua ntej ntawm tus kab mob uas ua rau COVID-19.
Cov neeg mob tiv thaiv kab mob yuav tsum tau txais cov tshuaj tiv thaiv?
Vim li cas CDC thiaj pom zoo tias cov neeg uas muaj kev tiv thaiv kab mob tiv thaiv kab mob tau txais koob tshuaj mRNA COVID-19 ntxiv los ntxiv rau 2-dose thawj koob tshuaj tiv thaiv kab mob mRNA COVID-19? Cov neeg uas muaj kev tiv thaiv kab mob los yog cov neeg siv tshuaj tiv thaiv kab mob yog nyob ntawm muaj kev pheej hmoo ntau rau tus kab mob COVID-19 hnyav .
Cov tshuaj tiv thaiv kab mob puas muaj kev tiv thaiv kab mob?
Nws yuav siv sijhawm ntev npaum li cas txhawm rau txhim kho kev tiv thaiv kab mob COVID-19 tom qab tau txais cov tshuaj tiv thaiv? tshuaj tiv thaiv COVID-19 qhia peb lub cev tiv thaiv kab mob kom paub txog thiab tawm tsam tus kab mob uas ua rau COVID-19.
