Kungani umhlaba round? adonsela phansi

Akukho muntu noma ibekelwe bazibuze ukuthi kungani umhlaba uyisiyingi. Phela, sonke manje kumnandi ukuzwa izindaba indlela abantu lasendulo emelelwa kudivayisi kanye ukuma iplanethi abahlala kuwo. Flat Earth, izindlovu, ufudu nezilwandlekazi ... Manje kusukela ebuntwaneni wazi konke mayelana eyindilinga ukuma Earth. Kodwa uyini owamangaza abantu: chaza isizathu ambalwa kuphela uzokwazi ke. Konke okunye ukuthatha isitatimende ukuthi "umhlaba uyisiyingi", njengenhlangano Axiom. Ngenhlanhla, abantu abanjalo njalo ngonyaka is lincipha: lukuluku elingokwemvelo nokutholakala kuthiwa zenza umsebenzi wazo.

Ngakho, kungani umhlaba uyisiyingi? Ukuze siphendule lo mbuzo, kumelwe sikhumbule esikwaziyo kumiswa zesimiso sonozungezilanga. Umbono ukusebenza, okuyinto wabe akhona kakhulu, sithi kuyisiqalo ujikelezisa igesi-uthuli ifu ezakhiwe inkanyezi emaphakathi - ilanga, bese izwe. Zonke kuyizinhlayiyana ujikelezisa omise isiyingi amandla elanga adonsela phansi esebenza, lokuqoqa nabo umzimba owodwa, bahlambalaza ubukhosi. Nokho, lokhu akusho ukuthi kungani umhlaba uyisiyingi, hhayi nganoma yisiphi isimo. Iqiniso lokuthi omunye imithetho eyisisekelo yonke yisifiso ngokuphelele zonke izidumbu impahla ukusebenzisa amandla ngangokusemandleni. Ngamanye amazwi, konke endaweni yonke izimisele ukuba ukuthula. Kunjalo ijamo eyindilinga. Zithwala umfutho yasendle okudonsa asakaze kuzo zonke izinhlangothi emthonjeni (kuleli cala - maphakathi iplanethi). Njengoba ziyizidalwa kakhulu alinganayo, umphumela uba ukwakheka komzimba eyindilinga, iphuzu ngalinye elikwazi amaqabunga equidistant kusuka isikhungo ezivamile. Noma yiluphi ushintsho yebanga (isibonelo, ukubukeka entabeni) futhi ephazamisa alinganayo ukungezwani ushintsho Vector yasendle okudonsa izinto. Ngemva kwesikhathi esithile, ukungalingani isazoqhubeka iqedwe, futhi ibhalansi ubuyiselwa emzimbeni ngandlela-thile (weathering, ukuphazamiseka mechanical). Ngakho, esinye sezizathu ezinkulu zokuthi kungani umhlaba uyisiyingi - isenzo ka amandla adonsela phansi. Yonke evelele, ezinkulu ngaphezulu komhlaba nendikimba esemkhathini. Ngaphezu kwalokho, ukwakheka umumo eyindilinga kubangelwa ikakhulu isimo liquid core eMhlabeni. Njengoba yaziwa, ukuma ibhola kuba lula ukunikeza igesi futhi uketshezi. UMhlaba has a ungqimba kuqhathaniswa ezondile cortex (le sobala contact surface) kuyinto olwandle of magma ketshezi red-hot. Lapho ukuqhuma kwentaba -ke lichitheke nezingqalathi yiqhwa. Kukhona umbono ubuye core ketshezi maphakathi planethi. I izimfanelo salokhu nokucabanga iyona Nebalinga ukubukeka kazibuthe odala imisinga amandla amakhulu maphakathi Earth.

By endleleni, uma ubheka ukuma emizimbeni enkulu yasezulwini esimisweni sonozungezilanga, khona-ke kuba sobala ukuthi wonke amaplanethi kukhona eyindilinga. Ngezinye izikhathi kukhona izimisele kancane aphume ukuma ngenxa aba-pole. isiqalo sakhe ke ubophekile ukuba ukujikeleza planethi emhlabeni axis awo. Kodwa ezincane isimiso somzimba semithambo - asteroyidi - ungaba cishe noma yikuphi ukuma. Isizathu salokhu yokuntuleka massiveness futhi, ngenxa yalokho, amabutho amancane okudonsa izinto. Ngaphezu kwalokho, ukujikeleza, Akhuthaza ukwakheka kwe-sphere, njengoba mhlawumbe abekho noma alanele.

Ngezinye izikhathi phezu izinkundla zingatholakala umbuzo yini izinkanyezi sonozungezilanga. Kuze kube muva nje kwathiwa bazitshela ukuthi uhlelo inkanyezi ingenye kuphela - ilanga. Nokho, Bayanda, it kwakuzwakala ngoba kucatshangwa ukuthi uhlelo lwethu - kabili. Ngaphandle Sun isihlabani yesibili, ogama khona kuze kungase kutholakale ngokungaqondile kuphela, kodwa igama isivele inikezwe - Nemesis. Ngenxa side orbit wawusondela Umhlaba ingekho eminyakeni engaphezu kuka kanye njalo eziyizinkulungwane ezimbalwa kuphela.
