IMisa Zomhlaba. I indaba ecatshangwe inkolelo-mbono yokuziphendukela i iplanethi ekwandiseni

Ngokusho kathisha yamuva lomkhathi, mass emhlabeni kuyinto 5,97 × ^{24 Okthoba} kilogram. izilinganiso Lonyaka lokhu ezidlula ibonisa ngokucacile ukuthi akusiyo ngokuphelele njalo. idatha yayo isukela kuze ku amathani ngonyaka izinkulungwane 50. Umhlaba iyona enkulu kunazo zonke ngobukhulu ubukhulu, mass kanye kwabantu phakathi amaplanethi okuqondene nakho kukodwa. Phakathi nesimiso sikanozungezilanga, iplanethi yethu yesithathu eLangeni eyesihlanu ngobukhulu phakathi kwabo bonke abanye. Iya ku-orbit okweqanda emhlabeni Sun at ibanga isilinganiso kwezigidi ezingu 149,6 amakhilomitha away.

Kusukela mass Zomhlaba uyashintsha, kunemibono eminingi phezu izitayela yalezi zinguquko. Ngakolunye uhlangothi, lesi silinganiso ngokuqhubekayo kwandisa ngenxa ukungqubuzana emkhathini ukuthi evutha emoyeni, shiya semali uthuli imali emhlabeni. Ngakolunye uhlangothi, i-ultraviolet emisebeni yelanga njalo ezidabula molecule yamanzi engenhla emkhathini, umoya-mpilo ne-hydrogen. Ingxenye hydrogen ngenxa isisindo sayo ukukhanya wakhipha kusukela emkhakheni okudonsa planethi esithinta ngesisindo sakhe.

Kusukela ekuqaleni kwekhulu le-19 namashumi okugcina eminyaka yawo imfundiso yokuziphendukela kwekhulu lama-20 Zomhlaba ukhulisa khona bekulokhu ethandwa kakhulu phakathi ososayensi emhlabeni wonke. Umbono yokwanda umthamo iplanethi iye yabangela kokuqagela ukuthi kwandisa nenqwaba Earth. Phakathi naso sonke isikhathi sokuba khona inkolelo-mbono yokuziphendukela ososayensi ezinhlanu ezahlukene ukufunda ongakhetha yayo kuye kwasikiselwa. Abacwaningi abaningi abavelele ezifana Kropotkin, Milanovsky, Steiner futhi Schneider, wagomela ukunwetshwa emhlabeni iyehla iyenyuka yayo cyclical. Dakill, Myers, Clube futhi Napier wachaza lokhu nokucabanga is unomphela exhunywe emhlabeni wazo futhi asteroyidi. Imfundiso ethandwa kakhulu wokwanda iye, wasikisela ukuthi umnyombo yokuqala iplanethi yethu lalinabashumayeli ndaba superdense, elisetendeni inqubo yokuziphendukela kwemvelo yaphenduka impahla evamile, okubangela ukunwebeka kancane kancane Earth. Kule minyaka engu-50 edlule ekhulwini elidlule leminyaka, eziningana zesayensi ovelele ezifana Dirac, Jordan, Dicke, Ivanenko futhi Saggitov, waveza umbono wokuthi amandla adonsela phansi incipha nge sikhathi, futhi lokhu kuholela ekuphelelweni ukwanda zemvelo nazo kulo mhlaba. Omunye umbono kwaba umbono Kirillov Neumann Blinov futhi Veselova ukuthi ukunwetshwa Umhlaba kubangelwa izizathu Cosmological ezihlobene wakudala ukwanda obuphathekayo benkolelo yazo ezindaweni isisindo sayo. Namuhla, semali ubufakazi ekuphikiseni la ezizathwini.

Imfundiso ye-elalanda iplanethi, esekelwe yokuthi nenqwaba Umhlaba njalo anda, manje ekugcineni saphuthelwa yiwo sikhalo salo. iqembu International eyayakhiwa ososayensi best in the world, ekugcineni iqinisekise ukuthi, ngakho namuhla, lo mqondo kungaba ngokuthula ukuya ku eshalofini zomlando ngokwesayensi.

Ngokusho isiphelo sesimiso geophysicists iqembu owenza lokhu kuhlola ngosizo isikhala izimoto zanamuhla, nenqwaba iplanethi enguMhlaba kuba kuqhathaniswa njalo. Umsebenzi omunye laboratories zocwaningo W. Xiaoping nozakwabo yashicilela isihloko ngokwengxenye lapho ethi egxilile ukuguquguquka engaba Umhlaba abeqeli ngalé 0.1 mm (ugqinsi unwele lomuntu) ngonyaka. Lezi izibalo zibonisa ukuthi nenqwaba Umhlaba asishintshi amagugu ezivumela ukuba ngikhulume ngokukhululeka ngokukhubazeka nokwanda kwalo.
