Kutheni umhlaba ngeenxa zonke? gravitation

Akukho mntu uya entandabuzo kunye uyazibuza ukuba kutheni umhlaba ngeenxa zonke. Ngapha koko, sonke ngoku kumnandi ukuva amabali indlela abantu bamandulo fanekisela isixhobo kunye nokumila umhlaba abahlala kuwo. Flat Umhlaba, iindlovu, ufudo kunye neelwandle ... Ngoku ukususela ebuntwaneni wazi yonke into malunga ungqukuva nokumila Umhlaba. Kodwa yintoni na ayimangalisi: achaze isizathu uya kukwazi kuphela nje ezimbalwa. Abanye ukuthatha ingxelo yokuba "umhlaba unjikelo", njengoko i saziwe. Ngethamsanqa, abantu abanjalo unyaka wonke ziba ezincinane: ukwazi zendalo kunye nokufumaneka benza umsebenzi wabo.

Ngoko ke, kutheni umhlaba ngeenxa zonke? Ukuze siphendule lo mbuzo, simele sikhumbule ukuba into esiyaziyo ukuyilwa kwenkqubo elanga. Hypothesis ukusebenza, nto leyo kwabelwana akhona ezininzi, uthi ekuqaleni a batshintshana ilifu gas-uthuli akhiwa inkwenkwezi central - ilanga, waza ke ihlabathi. Zonke yamasuntswana kwamaphiko kwindawo yazo setyhula, amandla omxhuzulane ebambeleyo, ukuqokelela nabo iqumrhu elinye yasezulwini. Noko ke, oku akuthethi achaze isizathu sokuba umhlaba ngeenxa zonke, hayi naluphi na olunye uhlobo. Isibakala sokuba omnye imithetho angundoqo indalo umnqweno ngokupheleleyo zonke imizimba eziphathekayo lokusebenzisa amandla kancinci kangangoko kunokwenzeka. Ngamanye amazwi, yonke iphela izimisele uxolo. Kunjalo shape ukulenza. Zithwala ngobunzulu yasendle omxhuzulane ukusasaza kuzo zonke izalathiso ukusuka kumthombo (kulo mzekelo - embindini planethi). Ekubeni makhulu bayalingana, umphumo Ukwakheka komzimba ungqukuva, ingongoma nganye apho asuka kuyo equidistant ukusuka kwiziko eqhelekileyo. Naluphi na utshintsho kwakukude (umzekelo, imbonakalo kwentaba) kwaye ephazamisana alinganayo ukutshintsha kwesimo kumda wesangqa yentsimi omxhuzulane. Emva kwexesha elithile, ukungalingani yona iza kupheliswa, kwaye intsalela ubuyiselwa ngandlela ithile (yemozulu, uphazamiseko mechanical). Ngoko ke, esinye sezizathu ezingundoqo sokuba umhlaba ngeenxa - isenzo imikhosi omxhuzulane. Bonke bephela, omkhulu ngakumbi ucaca ngakumbi umzimba yasezulwini. Ukongeza, ukuyilwa kwemilo ungqukuva kungenxa yemeko ulwelo lwe ezingundoqo komhlaba. Njengoko yaziwa, imilo ibhola kulula kakhulu ukuba irhasi kunye engamanzi. I Umhlaba umaleko obhityileyo ngokwentelekiso uthinte (qha kumphezulu okubonakala) yi ulwandle iziqina ulwelo ebomvu-eshushu. Xa mlilo iqhuma oko iphalale iqina. Kukho ingcamango yokuba naye engundoqo ulwelo embindini planethi. Ezi zinto zifuneka kuqala ukuze le ngqikelelo imizamo ukucacisa imbonakalo lo mhlaba otsalayo okuvelisa imisinga amandla amakhulu embindini Yomhlaba.

Ngendlela, ukuba ukhangela imilo imizimba yasezulwini enkulu kwinkqubo solar, ngoko kuba kucacile ukuba zonke neeplaneti ukulenza. Maxa wambi kukho zityediwe omncinane imilo ngenxa flattening kwi zezibonda. imvelaphi yakhe inyanzelekile ukuba ukujikeleza umhlaba ehlabathini axis yayo. Kodwa inkqubo yomzimba amancinci - izijikelezi - unokuba phantse nayiphi na imilo. Isizathu soku ukunqongophala massiveness kwaye, ngenxa yoko, imikhosi ezincinane omxhuzulane. Ukongeza, ujikelezo, ikhuthaza ukuyilwa amanqanaba, njengoko ezisenokungafumaneki okanye ayanelanga.

Ngamanye amaxesha le foram ingafunyanwa umbuzo wokuba yintoni njengeenkwenkwezi langa. Kude kube kutshanje bekucingelwa ukuba inkqubo nkwenkwezi enye kuphela - ilanga. Iya isanda, Noko ke, wakhalisa kwinkolelo yokuba inkqubo yethu - i kabini. Ngaphandle Ilanga yeyona nkwenkwezi yesibini, busaqhubeka kuze kube ngokungangqalanga kuphela, kodwa gama sele unikwe - Nemesis. Ngenxa orbit indlela yayo evuthelweyo uMhlaba lungenzeki ngaphezu kweminyaka kanye amawaka ambalwa.
