Cov anisotropies tshwm rau ntawm daim ntawv qhia ua kom txias dua xiav thiab sov dua thaj ua rau thaj. … Cov anisotropies no nyob rau hauv daim ntawv qhia qhov kub thiab txias sib haum mus rau thaj chaw ntawm varying density fluctuations nyob rau hauv lub ntiaj teb thaum ntxov. Thaum kawg, lub ntiajteb txawj nqus yuav rub tau qhov kev hloov pauv ntawm qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.
Vim li cas CMB thiaj tseem ceeb?
CMB pab tau rau scientists vim nws pab peb kawm seb lub qab ntuj khwb tau tsim li cas. Nws nyob ntawm qhov kub tsis sib xws nrog qhov hloov pauv me me uas pom nrog lub tsom iav kom meej.
Vim li cas thiaj kuaj tau anisotropies hauv microwave keeb kwm tseem ceeb?
Kev ntsuas qhov tseeb ntawm lub zog spectrum ntawm nruab nrab-teev thiab me meCMBR anisotropy yuav qhia peb cov ntsiab lus tseem ceeb txog cov txheej txheem lub cev tshwm sim hauv peb lub ntiaj teb thaum thawj ob peb lab xyoo.
Dab tsi yog qhov tseem ceeb ntawm kev hloov pauv hauv cosmic microwave keeb kwm?
Lub cosmic microwave keeb kwm yav dhau yog cov hluav taws xob tom qab uas tshuav los ntawm qhov kub kub Big Bang. Nws qhov kub thiab txias tsis tshua muaj sib xws thoob plaws lub ntuj. Txawm li cas los xij, qhov hloov pauv me me lossis qhov hloov pauv (ntawm ib feem ntawm ib lab theem) tuaj yeem muab kev pom zoo rau hauv keeb kwm, kev hloov pauv, thiab cov ntsiab lus ntawm lub ntiaj teb.
Vim li cas thiaj muaj anisotropies hauv CMB?
Qhov kub anisotropies ntawm CMB kuaj pom los ntawm COBE yog ntseeg tau los ntawm kev tsis sib xws hauv kev faib cov teeb meem ntawmlub sij hawm ntawm recombination.

Vim li cas cov anisotropies thiaj li tseem ceeb?
Cov anisotropies tshwm rau ntawm daim ntawv qhia ua kom txias dua xiav thiab sov dua thaj ua rau thaj. … Cov anisotropies no nyob rau hauv daim ntawv qhia qhov kub thiab txias sib haum mus rau thaj chaw ntawm varying ceev hloov pauv nyob rau hauvlub ntiaj teb thaum ntxov.
Vim li cas txoj kev tseem ceeb tseem ceeb rau kev tswj xyuas qhov project?
txoj kev tseem ceeb tso cai rau pab pawg txheeb xyuas cov haujlwm tseem ceeb tshaj plaws hauv qhov project. … Qhov no muab kev nkag siab ntau dua rau koj qhov project ncua sij hawm thiab kev sib raug zoo ntawm cov haujlwm, ua rau koj nkag siab ntau ntxiv txog lub sijhawm ua haujlwm twg koj tuaj yeem hloov kho, thiab qhov twg yuav tsum nyob ib yam.
Vim li cas lub ntsiab lus tseem ceeb yog qhov tseem ceeb?
Grand mean centering sub lub ntsiab lus loj ntawm tus kwv yees siv qhov txhais los ntawm tag nrho cov qauv (X).. Vim li cas Grand txhais tau tias qhov chaw tseem ceeb? Lub ntsiab lus tseem ceeb yog qhov siv tau rov ntsuas duauas pab nrog kev txhais cov ntsiab lus cuam tshuam nrog kev cuam tshuam, nws txhais tau li cas, lossis qhov sib txawv ntawm txhua qib;
Dab tsi yog qhov tseem ceeb thiab vim li cas nws tseem ceeb los txheeb xyuas koj qhov tseem ceeb?
Qhov tseem ceeb yuav coj koj hauv kev txiav txim siab hauv lub neej thiab ua rau koj taug qab. Qhov tseem ceeb tshaj plaws, qhov tseem ceeb tshaj plaws yuav ua rau koj ntseeg siab hais tias "tsis yog." Lawv pab koj txheeb xyuas qhov xav tau tiag tiag hauv koj lub neej, piv rau lwm tus xav tias tseem ceeb.
Vim li cas qhov tseem ceeb ntawm qhov muaj zog thiab qhov tsis muaj zog yog qhov tseem ceeb?
Nws yog ib qho tseem ceeb rau qhov tseem ceeb ntawm qhov ua tau zoo thiab qhov tsis muaj zog vim qhov no pab lub tuam txhab txiav txim siab txog thaj chaw uas lawv yuav tsum tau txhim kho ntxiv rau thaj chaw uas lawv ua tau zoo hauv. Vim li cas lub zog thiab qhov tsis muaj zog tseem ceeb?
