Kungani singavele kabusha emkhathini izilwane nabantu?

Kungani singavele kabusha emkhathini? Lo mbuzo ekhathaza ososayensi iminyaka leminyenti. Siyini isizathu? izifundo eziningi sezenziwe, eyaqinisekisa ukuthi ukukhiqizwa emkhathini akunakwenzeka. Yiqiniso, umcabango singenzeka. Kodwa uma ingane ozozalwa okunempilo?

Izifundo zokuqala

Ngakho kungani akukwazi yokuzalanisa isikhala? Izifundo zokuqala Kwakuseshwa phakathi nenkathi yamaSoviet. Abahlanganyeli kuqala ukuhlola kwakungamadodana rat. Manje-ke ukuthi lezi zilwane baba amaphayona. Amagundane wakhulelwa emkhathini, wanika inzalo iphila ngokuphelele. Nokho, abantu abadala sifo iyafa ngokushesha kakhulu lapho kuqala namazinyane azo ozalwa. Emuva Emhlabeni, amagundane nobunzima. Okokuqala, Young wayengasakwazi ukunyakazisa evamile, ngoba akhiwa nemibandela weightlessness.

Emkhathini, wavakashelwa izilwane eziningi. Kwenzeka isimanga, ukuthi abe uhlobo lwenkawu olungavamile nezinja wabona umhlaba wethu uzungeza emzileni kuneNingizimu abantu. The French kwathunyelwa emkhathini, ngisho namakati. Izilwane yokuqala wandizela phezu inyanga, babe izimfudu.

Zonke ucwaningo Kwakuseshwa ukuze uthole izimpendulo zemibuzo eminingi. Futhi kwakungeyona nje kungenzeka indiza zero amandla adonsela phansi. I ucwaningo kwadingeka ukuba uphendule umbuzo othi kungani akunakwenzeka ukukhiqizwa kabusha emkhathini.

Kushisa bhé kule ndawo emkhathini

Ongoti NASA olwenziwa eziningi ukuhlolwa futhi wafakazela ukuthi akunakwenzeka ukuba ukukhiqizwa kabusha emkhathini. Izilwane ezikhulisela kubumbi zero amandla adonsela phansi, hhayi kuphela wayengasakwazi ukunyakazisa evamile, babengakwazi zikwazi ukuveza inzalo. Lokhu kwabonisa ukuthi iphupho komnikazi nokunqoba amaplanethi ezikude futhi ahlale amaphupho nje isintu akusho usungula ukuvikelwa anti-emisebeni for mkhathi.

Ucwaningo luye lwabonisa ukuthi i-proton izinhlayiya njalo kuthinte ntu emkhathini. Kwaphawulwa ukuthi emisebeni ukwazi "abilayo" imibungu owakhulela ngaphandle emkhathini woMhlaba. Izizukulwane ngeke bamane nje abakwazi nokuzala.

Kuzokwenzekani izingane zicatshangwe isikhala

Ososayensi baye baphetha ngokuthi intombazane, ngubani unina amkhulelwe isikhala, ezikhiqiza amaqanda bayabulawa wonke amaqanda esimeni abonisa ukungavuthwa. Kodwa akhiwa kule fetus ezinhlanu ngikhulelwe kakade. Leli qiniso kuyabacasula. Ngamanye amazwi, la mantombazane zimane ezingenalusizo. Ngaphezu kwalokho, emisebeni emkhathini futhi kakhulu kuthuntubeza ikhono lomuntu izinga isidoda. Kwaphawulwa ukuthi emisebeni ephezulu amandla futhi umonakalo kuyizinhlayiyana isidoda kakhulu. Ngenxa yalokho lezi zinguquko endaweni yonke kungenziwa wakhulelwa izingane ukukhubazeka kwezakhi zofuzo. Yingakho kuyinto engenakwenzeka ukuba ukukhiqizwa kabusha emkhathini.

izinhlayiya Kuyingozi nemisebe

Esikhaleni we yonke enkulukazi, kukhona izinto eziningi okuphazamisayo. Phakathi kwabo ivelele emisebeni cosmic, okuvela kwimithombo ehlukahlukene, kanye izinhlayiya ezindiza ukusuka elangeni. Mhlawumbe abaningi benu bazi ukuthi emkhathini ngaphandle emkhathini zabiwa proton ephezulu amandla, futhi ion libe nzima ngokwengeziwe, okuyinto kalula kungalimaza i-DNA. Maye, ngisho nobuchwepheshe yesimanje ungavumeli ukudala mkhathi ezazizovikela umzimba womuntu kusuka imiphumela emibi radiations ahlukahlukene nezinhlayiyana.

Ososayensi bathi kwakheka yimuphi uhambo ekujuleni yonke iphela emuva ekuqaleni. Lokuzaliswa emkhathini akunakwenzeka kuze kungabikho ekhethekile Ukuvikelwa emisebeni. Mhlawumbe, lobu buchwepheshe kuyoba esikhathini esizayo. Okwamanje, i-DNA ezidingekayo sokuthuthukisa omzimba womuntu, iyashesha ukuzwela uma ngemisebe, okuyinto emkhathini. Ukuhlolwa kwenziwa izilwane luye lwabonisa ukuthi inzalo owakhulela ngaphandle emkhathini akububonisi amaqanda bukhoma. Ukubhujiswa kwayo kwenzeka engxenyeni yezinyanga ezintathu 2nd noma 3rd yokukhulelwa.
