<prompt> Fingqa isihloko: Kwenzeka kanjani ukuba insimbi ihlakazeke kulo lonke i-mantle yomhlaba engamakhilomitha angu - 3 200 ubude eminyakeni engaphezu kwezigidi eziyizinkulungwane ezine edlule? Lo mbuzo uye wadida ososayensi, abaningi becabanga ukuthi imbangela iwukushayisana kwama-asteroid, kodwa manje kuye kwethulwa inkolelo-mbono entsha - imvula yensimbi. Ngokuhlaziya kabusha iphuzu lokuhwamuka kwensimbi, ucwaningo luye lwathola ukuthi izimo eMhlabeni wasendulo zaziyobangela ukuba insimbi ine emhlabathini. Ososayensi eNew Mexico banombono omusha ngemvelaphi yensimbi yoMhlaba. Ucwaningo lubonisa ukuthi insimbi yayingaphenduka umhwamuko lapho ama - meteorite eshaya uMhlaba osemusha, njengoba kuboniswe emfanekisweni womculi ongenhla. Khona-ke umusi wawuyobe usukhuphukele phezulu njengamafu, uhlanganiswe bese unetha phezu komhlaba wethu. Lolu cwaningo lwenziwa ngomshini i-Z eSandia National Laboratories e-Albuquerque, eNew Mexico. Lo mshini ungumkhiqizi wamandla kagesi anamandla kunawo wonke emhlabeni. Ngokutadisha umfutho odingekayo wokushaya insimbi, bathola ukuthi inani lalingamaphesenti angu-40 ngaphansi kwalokho okwakulindelekile. Izazi ze-astrophysics zithi lokhu kwehla kwengcindezi - ama - gigapascals angu - 507 GPa uma kuqhathaniswa nama - GPa angu - 887 - kwafinyelelwa kalula ezigabeni zokugcina zokwakheka koMhlaba. Ngenxa yokuthi ososayensi bezinkanyezi bebelokhu becabanga ukuthi kunzima ukuhwamula insimbi, abakaze bacabange ngokuhwamuka njengenqubo ebalulekile ngesikhathi kwakhiwa uMhlaba nenhliziyo yawo, kusho umcwaningi oyinhloko uDkt. Rick Kraus. Abacwaningi bakha umgomo - oqukethe ipuleti lensimbi elingamamitha-skwele angu-0.008 5mm nobukhulu obungamamitha-skwele angu-200 - abaqhumisa ngawo amapuleti e-aluminium ahamba ngesivinini esingamakhilomitha angu-25 ngomzuzwana. Kulomfutho wokushayisana, amagagasi anamandla adalwa ensimbi ayibangela ukuba icindezeleke, ishise futhi iphephuke. Imiphumela yabonisa ukuthi umkhawulo wokuhwamuka wensimbi ungaphansi ngamaphesenti angu-40 kunalokho obekucatshangwa ngaphambili. Kodwa ngokuhlola kwethu, siye sabonisa ukuthi kulula kakhulu ukushaya insimbi ibe umusi. Umphumela walokhu wawuyoba ukuthi ucezu lwensimbi oluqinile, ngemva kokushayisa uMhlaba mhlawumbe njenge...  <response>: Ososayensi eNew Mexico banombono omusha ngemvelaphi yensimbi yoMhlaba. Ngaphambili kwakungacaci ukuthi insimbi yayisakazeka kanjani kulo lonke i-mantle. Kodwa ucwaningo lubonisa ukuthi iphuzu lokuhwamuka kwensimbi liphansi kunalokho obekucatshangwa. Lokhu kusho ukuthi kwakufanele iphenduke umhwamuko lapho amatshe eshaya uMhlaba wasekuqaleni. Bekuzokwenyuka kube yizicucu bese kwehla imvula phezu komhlaba.
