Antimatter

Kev sib sau ntawm teeb meem thiab antimatter

Thaum koj hnov ​​lo lus antimatter Nws zoo li qee yam tshwj xeeb ntawm zaj yeeb yaj kiab. Txawm li cas los xij, nws yog ib yam dab tsi tag nrho tiag tiag thiab peb txawm emit nws hauv peb lub cev. Antimatter tau dhau los ua ib qho tseem ceeb rau kev tshawb fawb vim nws pab peb nkag siab ntau yam ntawm lub ntiaj teb, nws txoj kev tsim thiab kev hloov pauv. Ib qho ntxiv, nws tau piav qhia ntau yam tshwm sim uas tshwm sim hauv kev muaj tiag.

Koj puas xav paub dab tsi muaj antimatter thiab yog vim li cas nws thiaj li tseem ceeb? Ntawm no peb piav txhua yam rau koj.

Antimatter yog dab tsi

Antimatter lus

Antimatter tshwm sim los ntawm ib qho ntawm cov sib npaug loj heev uas muaj hom lus uas tsuas yog cov kws tshaj lij ntawm lub cev thiab cov kws tshaj lij muaj peev xwm decipher. Cov kev sib npaug no zoo li qee yam tsis raug thiab uas, ib txwm dhau, tom qab muaj ntau qhov sib npaug, nws yog ib qho ib txwm muaj qee qhov ua yuam kev. Txawm li cas los, qhov no yog qhov tseeb tag nrho thiab antimatter muaj tseeb.

Nws yog ib yam khoom tsim ua ntawm lub npe hu ua antiparticles. Cov xaj no yog qhov zoo ib yam li peb paub tab sis nrog hluav taws xob sib tshooj lig. Piv txwv li, antiparticle ntawm ib qho hluav taws xob uas nws lub luag haujlwm tsis zoo yog ib qho zooCov. Nws yog cov sib npaug nrog cov sib xyaw ua ke, tab sis muaj lub luag haujlwm zoo. Nov yog qhov yooj yooj yim no thiab yog leej twg xav ua kom nyuaj tshaj no nws tsis yog lawm.

Cov ntawv particle thiab antiparticle mus rau hauv khub. Thaum ob leeg sib tsoo, lawv rhuav tshem ib leeg thiab ploj tag nrho. Raws li qhov tshwm sim ntawm qhov sib tsoo no, lub teeb ci ci tau tsim. Cov thooj uas tsis muaj nqi, xws li neutrinos, yog lawv tus kheej xav tias yog lawv tus kheej antiparticle.

Muaj qee qhov theories uas xav txog cov lus hais hauv qab ntawm Majorana lub npe thiab nws ua raws tias cov teeb meem tsaus kuj tseem tuaj yeem yog Majorana hais, uas yog hais tias lawv tus kheej yog lawv cov tshuaj tiv thaiv thiab cov khoom tawg thaum tib lub sijhawm.

Dirac kev sib npaug

Antimatter yog dab tsi

Raws li peb tau tham txog, antimatter tshwm sim los ntawm kev kawm txog zauv thiab kev sib npaug ntawm lub cev ntev. Kws kho mob Paul Dirac, kawm txhua yam no hauv xyoo 1930. Nws sim ua ke los ua kom muaj zog ntawm lub cev tam sim no hauv ib qho: tshwj xeeb kev sib raug zoo thiab kev teeb meem ntawm ib lub tshuab. Ob qhov tam sim no sib koom ua ke nyob rau hauv ib qho kev sib kho theoretical kuj pab tau kev nkag siab ntawm lub ntiaj teb.

Niaj hnub no peb paub qhov no raws li Dirac kab zauv. Qhov no yog qhov sib luag kom yooj yim, tab sis ib qho uas cuam tshuam tag nrho cov kws tshawb fawb thaum lub sijhawm. Qhov sib npaug kwv yees ib yam dab tsi uas zoo li tsis yooj yim sua, tawg nrog lub zog tsis zoo. Dirac cov kab zauv hais tias qee qhov lus tuaj yeem muaj zog qis dua li so. Ntawd yog, lawv tuaj yeem muaj lub zog tsawg dua li lawv muaj thaum lawv ua tsis muaj dab tsi kiag liCov. Cov lus hais no nyuaj rau cov kws tshaj lij to taub. Yuav ua li cas koj lub zog tsawg dua li koj tsis tau ua dab tsi, yog tias koj tsis ua dab tsi los ntawm koj tus kheej?

Los ntawm qhov no nws tau pom tias cov hais tawm tau muaj lub zog tsis zoo. Tag nrho cov teeb meem no qhov kev muaj tiag uas muaj ib lub hiav txwv ntawm cov zog uas muaj lub zog tsis zoo thiab uas tsis tau pom los ntawm physics. Thaum ib qho qub particle jumps los ntawm qis zog hluav taws xob theem mus rau qhov siab dua, nws tawm qhov sib txawv hauv qhov qis zog theem nws los ntawm. Tam sim no, yog tias qhov me me muaj qhov tsis zoo, lub qhov yuav muaj qhov tsis zoo lossis lub qub yog dab tsi, kev them nyiaj zoo, uas yog, positron. Nov yog qhov tswv yim ntawm antiparticle tau yug los.

Antimatter nyob qhov twg?

Cov yam ntxwv ntawm antimatter

Thawj antimatter hais kom tau ntes yog cov neeg los ntawm cosmic rays siv huab huab. Cov koob yees duab no tau siv txhawm rau txhawm rau txhawm rau pom cov kab ntawv. Lawv tawm cov roj uas tom qab tso cai, koj tuaj yeem paub txoj hauv kev lawv muaj. Tus kws tshawb fawb Carl D. Anderson muaj peev xwm siv magnetic teb li, Thaum cov xaim hluav taws xob hla hauv chav, txoj kev yuav khoov rau nws cov nqi hluav taws xob. Nyob rau hauv txoj kev no nws tau ua tiav tias qhov particle mus rau ib sab thiab antiparticle mus rau lwm yam.

Tom qab ntawd, cov kab mob tawm tsam thiab cov antineutrons tau tshawb pom thiab txij thaum ntawd los, cov kev tshawb pom muaj ntau dua thiab ntau dua. Antimatter tau paub zoo dua. Peb lub ntiaj teb yog tas li tau bombarded nrog antiparticles uas yog ib feem ntawm cosmic rays. Dab tsi yog qhov ze tshaj rau peb yog dab tsi cuam tshuam rau peb.

Peb tuaj yeem hais tias peb tus kheej emit antimatter vim muaj tus qauv ntawm lub cev. Piv txwv li, yog tias peb noj cov txiv tsawb, vim yog zom ntawm poov tshuaj -40, yuav muab ib daim ntawv tshaj tawm txhua txhua 75 feebCov. Qhov no txhais tau tias yog tias peb pom cov poov tshuaj -40 nyob rau hauv peb lub cev, nws yuav yog qhov peb tus kheej yog qhov chaw los ntawm antiparticles.

Dab tsi yog nws rau

Antimatter

Muaj tseeb koj yuav hais tias dab tsi yog qhov kev siv ntawm kev paub tias muaj antimatter. Zoo, ua tsaug rau nws, peb muaj ntau yam kev txhim kho hauv daim teb tshuaj. Piv txwv li, nws yog dav siv nyob rau hauv positron emission tomography. Cov lus hais no tau siv los ua kom muaj peev xwm tsim qee cov duab ntawm tib neeg lub cev ntawm kev daws teeb meem siab. Cov duab no muaj txiaj ntsig zoo rau kev kuaj xyuas kom paub yog tias peb muaj qog loj dua lossis nthuav dav nws qhov kev hloov pauv. Kev siv cov tshuaj tua kabmob los kho mob cancer kuj tseem kawm.

Nyob rau hauv lub neej yav tom ntej, antimatter tuaj yeem ua qhov tseem ceeb hauv kev tsim hluav taws xob. Thaum teeb meem thiab antimatter annihilate, lawv tawm hauv lub zog hauv daim ntawv zoo ntawm lub teeb. Ib gram ntawm antimatter ib leeg yuav tso tawm lub zog sib npaug rau lub foob pob nuclear. Qhov no yog txaus ntshai.

Qhov teeb meem niaj hnub no nrog kev siv dag zog ntawm antimatter rau lub zog yog nws qhov chaw cia. Yog ib yam dab tsi uas peb nyob deb heev los ntawm kev daws. Txhua txhua gram ntawm antimatter nws xav tau txog 25.000 trillion kilowatt teev zog.

Nws tseem ua haujlwm los piav qhia tias vim li cas peb muaj nyob. Pib, raws li Big Bang Tswv Yim, lub hauv paus pib ntawm ob qho teeb meem thiab antimatter yuav tsum tau tshwm sim los ntawm tus qauv ntawm tag nrho cov kev ntsuas. Yog tias muaj li no tiag, peb yuav ploj mus. Yog li, nws yog qhov tsim nyog yuav tsum muaj tsawg kawg 1 ntu ntawm teeb meem rau txhua yam kev ua yeeb yam.

Kuv vam tias cov ntaub ntawv no tau qhia meej koj tsis ntseeg siab txog antimatter.
