Zingaki izinkanyezi esimisweni sonozungezilanga? Ngo sanda kukora namuhla, ukuthandwa zokuxhumana nezinye izingxenye zombuso Runet ungakwazi ngokuvamile ukuthola efanayo umbuzo / poll. Ngokuvamile, kuhambisana amazwana mayelana Bakwethu nomqondo ubani ngokuyinhloko abaqondi isakhiwo ikhaya lethu cosmic. Yebo, zingaphezu bangaki izinkanyezi esimisweni sonozungezilanga? Yeka umbuzo engenangqondo? Lokho umsebenzi mayelana izinkanyezi eziningi kanjani emthaleni wethu, futhi kwakuyoba nzima kakhulu, futhi kunengqondo ukusetha. Kodwa hhayi konke ngakho elula! Ugxile inhliziyo le ndaba, ungakwazi bethola izinto ngokuphelele emangalisayo. It kuvela ukuthi phakathi kwezazi yesimanje sina umbuzo uwukuthi kufanele kwenziwe kanjani izinkanyezi eziningi zesimiso sonozungezilanga. Futhi manje umbuzo akuyona mayelana ethandwa abafuna ukuzwa nemibono pseudoscientific ngemvelaphi emhlabeni, ukuvakasha alien noma ukwenza itulo global, kodwa isazi sezindikimba ezisemkhathini ihlonishwe ngempela.
Kuiper Belt kanye Oort ifu
Uma kungenjalo wonke umuntu, khona-ke ngokuqinisekile iningi lezakhamuzi is Ukwakheka kwamaplanethi yethu eyaziwa : wesimiso sikanozungezilanga amaplanethi eliwumhlaba, ehlukanisiwe lonke le nguzunga ibhande igesi amakhulu i-Jupiter, sizungezwe amasongo Saturn, i-Neptune ezikude nokunye. abantu Kuyaphawuleka ezimbalwa, uma akusiyo unesithakazelo esikhethekile ku lesi sihloko, kuyaziwa ukuphuca i-Pluto kusukela isimo iplanethi. Iqiniso liwukuthi eminyakeni emibili senkulungwane izidumbu zitholwe ngaphandle kwe-umzila wokuzungeza kwalo, Pluto akuyona eliphansi in ubukhulu. Ngokokuqala ngqá kusukela ezinsukwini ngezikhwepha yaseGrisi yasendulo, kwaphakama umbuzo ngaphambi izazi zezinkanyezi: "Futhi, empeleni, ngokufanele ngokuthi iplanethi?" Ngenxa yalokho we ukuvumelana owamukelwa futhi ukwamukelwa of inombolo ngemibandela Pluto yakhethwa iplanethi yemifino, njengoba svezheotkrytye Eris, Sedna, nabanye. Lezi izinto amehlo eziningi futhi njalo evulekile ososayensi nomzimba ngaphezulu. Basuke bagxila izikhathi ezimbili ezikude elangeni kuka emzileni Neptune, futhi waziwa ngokuthi Kuiper Belt. Nokho, ukucwaninga kanzulu njalo engena isimiso sonozungezilanga lezinkanyezi ezinomsila uyaqiniseka izazi zezinkanyezi ukuthi avelaphi - hhayi Kuiper Belt. Ngokusho imiqondo yesimanje, namanje izikhathi eziyizinkulungwane, at ibanga unyaka owodwa ukukhanya kungenye disc of lokuhlushwa okuqinile izindikimba zasezulwini. Kwaba yokucasukela yakhe futhi kuholela nsada gqwa ku engaba engaphakathi isimiso sonozungezilanga lezinkanyezi ezinomsila bombardment ongokoqobo amaplanethi efana Saturn, Mars ne-Earth. Kucatshangwa izinto ku -Oort ifu, kudala kwamiswa eduze Sun, kodwa kamuva bahlakazeka kwi-space, ukuphotha manje emzileni kude. Kodwa yini ebangela ukuba ngesiphazamiso kwalezi futhi ebangela ukuba ngezikhathi phindela ilanga?
Nemesis
Futhi lapha umbuzo mayelana izinkanyezi eziningi kanjani isimiso sonozungezilanga uzuza kungukuthi bebahleka, kodwa okubi ngempela. Phakathi nawo-80s ngu kwezazi Jack Sepkoski noDavide Raup sekuthiwe umqondo wokuthi ukuphila eMhlabeni ezithi azifane, yabekwa a nokuqothulwa njalo enviable - e iminyaka eyinkulungwane 26-30. Nokho, izimbangela zezinkumbulo lezi ukuqothulwa, kwezazi bahluleka ukufaka. Kulesi sisekelo ke wazalwa imfundiso yokuziphendukela umsuka ezisemkhathini kwethuba lokuba kwenzeke inhlekelele - noma kunalokho, meteorite. Ososayensi abaningana kuze kube manje zisikisela ukuthi Sun angase abe inkanyezi-double, okuyinto yemifino dim obomvu (ngoba namanje akekho oqaphelile), kanye perturbs ngefu i-Oort esikhathini esibekiwe, okuholela bombardment cosmic Zomhlaba ubhubhise konke ukuphila . yemifino yezinto obomvu okuthiwa Nemesis. Uzokwenza kufanele kuphawulwe ukuthi kucatshangwa zangempela Nemesis kulezi zinsuku kakhudlwana futhi obuthaka ngaphezulu. Lokhu kunomthelela yokuntuleka impumelelo emkhankasweni wakhe, futhi ukwehluleka ukufakazela bombardment gqwa, futhi ekugcineni zokungabaza version yalesi yokuqothulwa njalo zezinto eziphilayo ophilayo Emhlabeni. Ngakolunye uhlangothi, izinkanyezi eziningi abadumile nje abalingani efanayo. Ngokwesibonelo, Galactic Umakhelwane wethu wavele - kanambambili inkanyezi simiso Alpha ne Proxima Centauri. Futhi mingaki iminyaka izinkanyezi, njengoba orbit emhlabeni isikhungo ezivamile gravity.
