Theories on the Formation of the Moon According to Astronomy
Wata, tauraron dan adam na duniya kaɗai, ya kasance abin mamaki da hasashe a tsawon tarihin ɗan adam. Masana ilmin taurari da masana kimiyya sun daɗe suna ƙoƙarin gano asalinsa, wanda ya haifar da ka'idoji daban-daban waɗanda ke ƙoƙarin bayyana yadda wannan jikin sama ya samo asali. A nan, mun zurfafa cikin wasu daga cikin ka'idoji mafi jan hankali game da samuwar Wata, waɗanda suka samo asali daga fannin ilmin taurari da ilmin taurari.
1. The Giant Impact Hypothesis
Ka'idar da ta fi shahara kuma wacce aka fi yarda da ita a fannin ilmin taurari ta zamani ita ce Hasashe Mai Girma na Tasirin Giant. A cewar wannan ka'idar, an samar da Wata ne bayan wani gagarumin karo tsakanin Duniya ta farko da wata duniyar Mars mai girman Mars mai suna Theia kimanin shekaru biliyan 4.5 da suka gabata.
Fundamentals of the Giant Impact Hypothesis
- Hatsarin Karo: Theia, wanda wani ɓangare ne na tsarin hasken rana na zamani, ya yi karo da Duniyar da ke kewaye da ita a kusurwa. Wannan tasirin ya fitar da tarkace mai yawa zuwa cikin kewayar Duniya.
- Samuwar Faifan Ɓacewa: Ɓacewar da ta faru sakamakon karo, wadda ta ƙunshi abubuwa daga Theia da Duniya, ta haɗu ta samar da faifan diski a kewayen Duniya.
- Haɗawa: Bayan lokaci, kayan da ke cikin wannan faifai sun haɗu ta hanyar haɗawa, daga ƙarshe suka samar da Wata.
Babban goyon bayan wannan ka'idar ya fito ne daga nazarin samfuran duwatsun wata da ayyukan Apollo suka dawo da su, wanda ya nuna kamanceceniya mai ban mamaki a cikin tsarin isotopic tsakanin Duniya da Wata. Wannan yana nuna cewa an yi Watan wani ɓangare ne daga kayan Duniya.
2. The Fission Theory
Wata tsohuwar hasashe, Ka'idar Fission, ta nuna cewa Wata a da yana cikin Duniya kuma ya rabu saboda saurin juyawar duniyar da ta fara.
Core Ideas of the Fission Theory
- Juyawa Mai Sauri: A farkon matakai, Duniya tana juyawa da sauri har aka jefa wani ɓangare na nauyinta cikin sararin samaniya.
- Samuwar Wata: Wannan taro da aka fitar daga jikin wata ya haɗu ya samar da wata.
George Darwin, ɗan Charles Darwin, ne ya gabatar da wannan ka'ida a ƙarshen ƙarni na 19. Duk da haka, tana fama da yin bayani game da yanayin kusurwa na tsarin Duniya-Wata kuma ba ta da kyau idan aka kwatanta da Babban Hasashe na Tasirin.
3. The Capture Theory
Ka'idar Kamawa ta yi hasashen cewa Wata wani jiki ne mai zaman kansa na sama wanda tasirin Duniya ya kama shi da ƙarfi.
Principles of the Capture Theory
- Tsarin Duniya Mai Yawo: Wata ya samo asali ne daga wani wuri a cikin tsarin hasken rana.
- Kama Nauyi: Yayin da Wata ke wucewa kusa da Duniya, nauyin Duniya ya kama shi ya kuma zauna a cikin kewayar sararin samaniya.
Duk da cewa wannan ka'ida ta yi bayani game da bambance-bambancen da ke tsakanin tsarin Duniya da Wata, tana buƙatar jerin abubuwan da ba za a iya tsammani ba. Misali, za a buƙaci jiki na uku don wargaza kuzarin motsi da kuma sauƙaƙe kamawa, wanda hakan ya sa wannan yanayin ba zai yiwu ba.
4. The Double Planet Hypothesis
Hasashe Biyu na Duniya ya nuna cewa Duniya da Wata sun haɗu a matsayin tsarin binary daga faifan accretion na farko na nebula na hasken rana.
Concepts of the Double Planet Hypothesis
- Haɗakarwa: Duniya da Wata sun haɗu a lokaci guda gefe da gefe daga yanki ɗaya na nebula na hasken rana.
- Haɗawa: Jiki biyu sun tara nauyi daga kayan da ke kewaye kuma suka girma a lokaci guda.
Wannan ka'ida ta nuna alaƙar da ke tsakanin Duniya da Wata. Duk da haka, ta kasa bayyana wasu halaye masu ƙarfi na tsarin Duniya da Wata na yanzu, kamar takamaiman motsin kusurwarsu.
5. The Synestia Theory
Wani sabon ra'ayi kuma mai cike da sabbin abubuwa shine Ka'idar Synestia, wacce ke nuna cewa Duniya da Wata sun samo asali ne daga wani dutse mai tururi wanda aka saba da shi wanda yake da siffar donut.
Details of the Synestia Theory
- Samuwar Synestia: Wani abu mai ƙarfi tsakanin Duniya da wani jiki ya haifar da synestia, wani tsari na ɗan gajeren lokaci wanda ya ƙunshi dutse mai tururi da narke.
- Samuwar Wata: Wata ya samo asali ne a cikin wannan haɗin gwiwa sannan daga baya ya bayyana yayin da tsarin ya yi sanyi ya kuma yi laushi.
Wannan ka'ida ta sauya daga ra'ayoyin gargajiya na tara da kamawa, maimakon haka ta mayar da hankali kan hanyoyin aiki masu ƙarfi da na thermodynamic bayan manyan karo. Tsarin ya sami karɓuwa saboda yuwuwarta ta bayyana kamanceceniya tsakanin isotopic da yanayin saurin kusurwa na tsarin Duniya-Wata.
Conclusion
Samuwar Wata ya kasance ɗaya daga cikin tambayoyin da suka fi jan hankali a kimiyyar taurari. Duk da cewa Hasashe Mai Girma na Tasirin Giant a halin yanzu yana kan gaba, wasu ka'idoji kamar Ka'idar Fission, Ka'idar Kamawa, Hasashe Mai Sauƙi na Duniya, da Ka'idar Synestia suna ba da gudummawa mai mahimmanci kuma suna nuna sarkakiyar abubuwan da ke faruwa a sama.
Kowace ka'ida tana kawo ra'ayoyi da ƙalubale na musamman, suna nuna yanayin binciken kimiyya da ke ci gaba. Yayin da fasaharmu da fahimtar sararin samaniya ke inganta yarjejeniya, ayyukan da za a yi nan gaba da bincike na iya samar da sabbin bayanai, wanda hakan zai iya haifar da fitowar sabbin ka'idoji gaba ɗaya. Duk da haka, neman fahimtar Watanmu yana ci gaba da ƙarfafawa da kuma jagorantar fannin ilmin taurari.
