Abahanga bahagarariye Kaminuza ya Harvard bavuga ko "umwicanyi" wa Dinosaurs yari mu majose yavutse ku nkombe y'izuba. Ingoma ya cosmic yari igice cyikintu cyashyizwemo rumaze kuri jupiter kumutwe.
Nk'uko ubushakashatsi bushya, umubiri w'ingano nini, wateje urupfu rw'ibinyabuzima binini, ntabwo yari asteroid hagati ya Jupiter na Mars, nk'uko abahanga mu bya simwe bamwe bemeza. Ukurikije abanditsi b'umurimo wa siyansi, ikintu cyo mu ijuru cyari igice cy'ingoma zo mu gicu cya oort. Kwiga IJAMBO RYIZA RY'UMUGORE MU MYAKA IZINA. Ibisubizo byubushakashatsi bwabanjirije byerekana ko amahirwe yo kwambuka inzira yubutaka bwizara ni gito.
Mu rwego rw'akazi gakorerwa, ibisubizo byatanzwe mu ngingo n'ibinyamakuru bya siyansi, bashoboye kumenya: rukuruzi rwa Jupiter rushobora gusunika abantu bagera kuri 20%. Ibice bitandukanijwe birashoboka cyane, bitandukanye nizindi joro igicu cya oort, utangara igihugu. Abashakashatsi bahagarariye kaminuza ya Texas muri Austin bashoboraga kumenya ko umushyitsi wo mwijuru yashoboraga kumenya ubugari bwa km 9.6 hanyuma akubite umubumbe ku muvuduko wa 71.840 km / h. Kugwa mu kintu cyinkoko kumpera yigihe cya chalk cyatumye habaho ikibaya, diameter yari kilometero 180. Inzira nini yavumbuwe iruhande rw'umujyi wa chiksulub (Mexico).
Inkomoko y'ingaruka Ikigo, cyasize inzira nini ku butaka bw'umunsi wa Yucatan, ntikiramenyekana. Dukurikije uburyo bumwe na bumwe, miliyoni 160 ishize, kubera kugongana asteroide, intera ya intera, yatumye dinosaur yazamutse. Nyuma isesengura utu ya Crater, mu Chiksulub basanze ko umubiri kirere ni carbonal chondrite - ubwoko kirere, bikaba bituma gusa 10% ya umubare asteroids y'ivy'isi y'izuba byagaragajwe mu umukandara nyamukuru. Abanditsi b'akazi, inyenyeri Arimo Leb na Amir Siraj bemeza ko bishoboka ko ibintu byinshi bivuye mu gicu cya oort gifite ibigize.
