Black Hole vs Wormhole
Lub qhov dub tsuas yog lub hnub qub tuag, uas yog compacted rau thaj tsam me me hauv qhov chaw. Ib tug wormhole yog ib qho hypothetical topological feature nyob rau hauv qhov chaw uas yuav tsim ib lub qhov ntawm ob lub ntsiab lus, tsim ib tug shortcut. Cov qhov dub thiab cov wormholes muaj keeb kwm lej loj heev thiab tseem ceeb heev hauv kev kawm txog cov yam ntxwv ntawm lub ntiaj teb. Cov kev ua tau zoo thiab kev suav hais txog qhov dub thiab lub qhov worm yog ib qho tseem ceeb hauv kev ua haujlwm xws li astrophysics, cosmology, theoretical physics thiab ntau yam haujlwm. Txawm hais tias qhov dub thiab qhov wormholes tsis to taub tag nrho lawv yog qhov tseem ceeb hauv kev nkag siab txog cov txheej txheem ntawm lub ntiaj teb tag nrho. Nyob rau hauv tsab xov xwm no, peb yuav tham txog dab tsi lub qhov dub thiab wormholes yog, lawv cov ntsiab lus, ib co ntsiab lus tseem ceeb tom qab qhov dub thiab wormholes, lawv zoo sib xws, thiab thaum kawg qhov txawv ntawm qhov dub thiab wormholes.
Dab qhov qhov dub yog dab tsi?
Astonishingly, thawj lub tswv yim ntawm lub qhov dub yog thawj zaug muab tso rau ntawm ib tug geologist. Nws yog John Michell uas tau piav qhia lub cev loj nrog lub siab ceev uas yuav tsis cia lub teeb khiav tawm ntawm qhov chaw. Nws tau thov qhov no rau ntawm tsab ntawv mus rau Henry Cavendish hauv 1783. Lub qhov dub yog lub hnub qub tuag, uas muaj ntau tshaj 3 hnub ci. Txoj kev xav dav dav tom qab qhov dub yog tias qhov kev khiav tawm ntawm qhov chaw ntawm lub qhov dub lossis qhov chaw saum npoo av yog ntau dua qhov ceev ntawm lub teeb. Qhov kev txwv qhov twg qhov kev khiav tawm yog sib npaug ntawm qhov ceev ntawm lub teeb yog lub npe hu ua qhov xwm txheej qab ntug. Qhov kev tshwm sim qab ntug yog qhov txwv qhov twg txawm lub teeb tsis tuaj yeem khiav tawm ntawm lub qhov dub. Sab hauv ntawm lub qhov dub feem ntau yog hu ua singularity. Ib tug singularity yog qhov chaw uas qhov ceev yog infinite, thiab lub ntim yog xoom. Dab tsi tshwm sim hauv qhov xwm txheej qab ntug tsis tuaj yeem ntes tau los ntawm kev txhais tau tias. Hauv qee qhov dub, muaj ib qho kev sib tw disc sab nraum qhov kev tshwm sim qab ntug. Cov discs no feem ntau yog tsim los ntawm kev nyiam huab hwm coj los ntawm lub hnub qub nyob ze hauv qhov system binary.
Dab tsi yog Wormhole?
A wormhole yog ib qho khoom siv dag zog lossis qhov tshwm sim uas yuav fold qhov peb seem ntawm qhov loj dua. Qhov no txhais tau hais tias ib qho shortcut yog tsim los ntawm qhov loj dua nyob rau hauv qhov chaw lub sij hawm nkhaus peb paub. Txawm li cas los xij, wormholes tsuas yog qhov tshwm sim theoretical xwb. Cov no tseem tsis tau pom los yog tsim nyob rau hauv kev xyaum. Einstein - Rosen Choj yog ib qho zoo tshaj plaws uas twb muaj lawm daim ntawv thov ntawm wormholes yog tias lawv puas tau kuaj pom. Lub Einstein - Rosen Choj tshaj tawm txoj kev luv los ntawm qhov chaw uas twb muaj lawm - lub sijhawm nkhaus.
Dab tsi yog qhov txawv ntawm Qhov Dub thiab Kab Mob?
• Cov qhov dub tau pom thiab kuaj pom hauv qhov chaw. Wormholes tsuas yog qhov tshwm sim hypothetical xwb.
• Lub qhov dub muaj lub hnub qub tuag, tab sis wormhole tuaj yeem ua qhov txawv txav ntawm qhov chaw lub sijhawm nkhaus lossis "twist" hauv qhov chaw lub sijhawm nkhaus hla qhov dav dua.
• Lub tswv yim ntawm wormholes tau qhia lub sijhawm ntev tom qab lub tswv yim ntawm qhov dub tau qhia.
