“Chilengedwe Chosaoneka” –Moyo Woyamba Wamaginito’ Kufalikira ku Cosmos

Akatswiri a zakuthambo padziko lapansi akufufuza mochulukira chidwi cha malo omwe mphamvu zazikulu za maginito zomwe zili m'chilengedwe chathu zimachokera -kuchokera ku Earth kupita ku Mars kupita ku Milky Approach kupita ku milalang'amba yambiri komanso kupita kumdima kwambiri., madera akutali a cosmos.

Kuwonongeka kwa Mars

Zaka theka la biliyoni m'mbuyomu, Njira ya maginito ya Mars yomwe imateteza nyanja yakuzama chifukwa Nyanja ya Mediterranean idazimitsidwa. beseni lozama lokwanira kumeza phiri la Everest ku Valles Marineris likuwonetsa zomwe zingakhale zotsatira za mbiri yakale. asteroid kukula kwa Pluto kugundana ndi Crimson Planet kuzimitsa maginito ake, kusamba Crimson Planet mu cheza oopsa, ndi kuwononga chilengedwe chake ndi tinthu ting'onoting'ono tomwe timachokera ku mphepo ya voltaic. Masiku ano, Dziko la Mars ndi dziko lachipululu lozizira kwambiri komanso lokhala ndi mpweya woipa 100 nthawi zowonda kuposa zapadziko lapansi.

Kuwongolera kwamphamvu kwa maginito kunapangitsa kuti pakhale gawo lofunikira poteteza chilengedwe ku mphepo yamkuntho ya voltaic ndikusunga dziko lapansi lonyowa komanso lokhazikika.. "Venus ndi Mars ali ndi maginito ocheperako ndipo sathandiza moyo, pomwe Mphamvu ya magnetic field ndizolimba komanso zimatero,"Wotchulidwa Sarah McIntyre ku Australia Nationwide College. "Tapeza zodziwika kwambiri ma exoplanets ali ndi maginito ofooka kwambiri, kotero iyi ndi nkhani yofunika kwambiri poyesa kupeza mapulaneti omwe mosakayika angakhalemo.”

Chithunzi chatsopano chodziwika bwino cha mtima wachiwawa wa Milky Manner (pamwamba) kuchokera ku Murchison Widefield Array, telesikopu yawayilesi kumadera akumidzi aku Western Australia, amavumbula timizere tagolide tambirimbiri toloza chinthu chofunika kwambiri maginito minda -momwe mlalang'amba wathu ungawonekere ngati maso a anthu angawone mafunde a wailesi.

“Moyo Wamaginito Wosaoneka”

Nthawi iliyonse akatswiri a zakuthambo amapeza njira yatsopano yopezera mphamvu za maginito kumadera akutali a mlengalenga., mosadziwika bwino, amazipeza, amaona Natalie Wolchover mu Quanta za mphamvu ya maginito yosaoneka yomwe imayenda mozungulira ndikuzungulira mozungulira milalang'amba ngati mizere ya chala., mzimu wosawoneka "magnetic soul".

"Maginito ndi chinthu choyambirira,’ akulemba, "kutsata njira yabwino kwambiri yobweretsera chilengedwe. Zikatero, maginito ofooka ayenera kukhalapo paliponse, ngakhale mkati mwa "voids" pa intaneti ya cosmic - yakuda kwambiri, madera opanda kanthu a chilengedwe chonse. Mphamvu ya maginito yopezeka ponseponse ikanamera minda yolimba imene inaphuka mu milalang’amba ndi magulu a milalang’amba.”

Mu 2019, akatswiri a zakuthambo anapeza 10 Kuwala kwa zaka mamiliyoni ambiri a malo okhala ndi maginito okhala ndi kukula konse kwa "filament" ya intaneti ya cosmic, gawo la intaneti yayikulu yomwe imadzaza malo ambiri, kulumikiza magulu awiri a nyenyezi otchedwa Abell 0399 ndi Abele 0401 zomwe zitha kugundana pang'onopang'ono.

Intaneti ya Cosmic

"Tikungofuna nsonga ya iceberg, mwina konse,"Wotchulidwa Federica Govoni a National Institute for Astrophysics ku Cagliari, Italy, omwe adatsogolera kuzindikira koyambirira pogwiritsa ntchito Low-Frequency Array (MALONJEZO) telescope ya wailesi kuti muwone mlatho wa plasma wotulutsa ma radio womwe ukufalikira pakati pa 2 magulu a milalang'amba omwe angakhale akuyandikira kuphatikizika. Zotsatira zikuwonetsa kuti maginito a intergalactic amalumikizana nawo 2 masango ndi zovuta malingaliro a tinthu mathamangitsidwe mkati mwa intergalactic sing'anga.

Intaneti ya cosmic, zatsimikiziridwa pomwe pano mu kayeseleledwe ka pc, ndi mikwingwirima ikuluikulu ya milalang’amba yolekanitsidwa ndi zipsinjo zazikulu.

Primordial magnetism ingathandizenso kuthetsa vuto lina lachilengedwe lomwe nthawi zambiri limatchedwa Hubble pressure, amaona Wolchover, kutchula kuti "mwinamwake ndi nkhani yokondedwa kwambiri mu cosmology."

Zodabwitsa za Hubble - "Constant in Space, Osati Nthawi”

"Pomwe Hubble Fixed imakhazikika pamalo aliwonse amderali panthawi yake, sichinakhazikitsidwe munthawi yake." akufotokoza Chris Fassnacht, pulofesa wa physics ku UC Davis ponena za tsoka lamakono mu cosmology, kapena "pressure", pomvetsetsa liwiro la kukula kwa chilengedwe​—kaŵirikaŵiri amatchedwa “Hubble Fixed”—chifukwa chakuti Large Bang, gawo lapakati pakusaka kuti apeze magwero a chilengedwe.

“Mphamvu Yamdima Ndi Yachilendo Kwambiri”

Akatswiri ena asayansi pakadali pano akuwonetsa kuti mphamvu zakuda ndi mphamvu ya 'chisanu' kuposa mphamvu 4 odziwika kale - yokoka, electromagnetic, ndi mphamvu zanyukiliya zolimba ndi zofooka. Komabe, ofufuza akuganiza kuti mphamvu yachisanu iyi ingathenso 'kuwonetseredwa' kapena 'kubisika' pazinthu zazikulu monga mapulaneti, kukhala kovuta kuzindikira.

"Mphamvu zakuda ndi zachilendo kwambiri, komabe kwenikweni ndizomveka kwa ine kuti sizinawonekere,” anatchulapo wasayansi wopindulitsa wa Noble Prize Adam Riess, poyankhulana ndi The Atlantic. "Sindikudziwa kuti mphamvu yakuda ndi chiyani. Mphamvu zakuda zimawoneka zolimba zokwanira kukakamiza chilengedwe chonse - koma kupezeka kwake sikudziwika, malo ake sakudziwika ndipo physics yake ndi yongopeka kwambiri. "

Mu a pepala idayikidwa pa intaneti mu Epulo ndikuwunika pansipa ndi Bodily Evaluate Letters, akatswiri a zakuthambo Karsten Jedamzik ndi Levon Pogosian, pulofesa wa physics ku Simon Fraser College ku Canada, amanena kuti mphamvu za maginito zopanda mphamvu m'chilengedwe choyambirira zingapangitse kukula kwa cosmic kukula komwe kukuwonekera panthawiyi.

“Monga Chamoyo Chokhazikika”

Akatswiri a zakuthambo ku Johns Hopkins motsogoleredwa ndi Nobel Laureate, Adam Riess, akuti ofufuza akufuna kufunafuna umboni wotsimikizika wa primordial magnetism yomwe ikuwoneka kuti ili pamalo aliwonse., ndi chinthu chosowa chimene chinapanga chilengedwe chonse.

"Aliyense akudziwa kuti ndi mtundu wazithunzi zazikulu,” adatero Pogosian. “Komabe kwa zaka zambiri, panalibe njira yodziwitsa ngati magnetism ili paliponse ndipo motero ndi gawo loyambirira la chilengedwe., chotero akatswiri ofufuza za chilengedwe anasiya kwenikweni kulingalira.”

Magnetism "imangofanana pang'ono ndi chamoyo chokhalamo,” adatero Torsten Enßlin, katswiri wa zakuthambo pa Max Planck Institute for Astrophysics, "Monga zotsatira za maginito amagetsi amawombera mumagetsi aliwonse aulere omwe amawasunga ndikutukuka. Adzafutukuka ndikukhala ndi zotsatira pamadera osiyanasiyana ndi kupezeka kwawo, malo amene amakula bwino.”
