Izazinzulu ezimele iYunivesithi yaseHarvard icebisa ukuba "ukubulala" i-dinosausi yayiyinxalenye ye-fat ephakama kwinkqubo yeSolar System. I-Cosmic Drummer yayiyinxalenye yento efakwe kwi-Jupiter kwikhosi enamacala entloko.
Ngokutsho kwesifundo esitsha, umzimba omkhulu, obangele ukusweleka kwe-Giaring, yayingeyonto ephakathi kweJupita kunye neMars, njengoko ezinye izazinzulu zikholelwa. Ngokutsho kwababhali bomsebenzi wesayensi, into yasezulwini yayiyinxalenye ye-bet kwilifu le-OORT. Ukufunda ii-comts zenza isangqa esinye esijikeleze amakhulu eminyaka. Iziphumo zezifundo zangaphambili zibonisa ukuba amathuba okuwela indlela yelizwe lamazwe amancinci kakhulu.
Njengenxalenye yomsebenzi owenziweyo, iziphumo ezazipapashwa kwinqaku lengxelo yesayensi, zikwazile ukufumana: ubuninzi be-jupiter banokutyhala ukuya kwi-20% isondele kwilanga, apho kuyenzeka khona i-gap. Inxalenye ezahluliweyo zizihlandlo ezili-10 ezinokwenzeka, ngokungafaniyo nezinye zegazi le-OORT, ingamangalisa umhlaba. Abaphandi abamele iYunivesithi yaseTexas eTexas e-Austin banokufumanisa ukuba iindwendwe zasezulwini zazinobubanzi be-9.6 km kwaye zabetha iplanethi ngesantya malunga ne-71,840 km / h. Ukuwa kwento ye-cosmic ekupheleni kwexesha le-chalk kukhokelele ekwenzeni i-crater, eyona incinci yayingama-180 yeekhilomitha. I-Gigantic Trail yafunyanwa ecaleni kwedolophu yanamhlanje yeChiklub (Mexico).
Imvelaphi yendawo yempembelelo, eshiye umkhondo omkhulu kwintsimi ye-Yucatan Peninsula, ayaziwa. Ngokutsho kwezinye iinguqulelo, kwiminyaka eli-160 eyadlulayo, ngenxa yokungqubana kwee-asteroids, kwavuka iMetooorite, eyayibangela ukuba idayiri yokupheliswa. Emva kohlalutyo lwejoyini ye-crater, i-chiksulub yafunyanwa ukuba umzimba we-cosmic yi-Carbonal Chondrite - uhlobo lweembono ze-asteroids echongiweyo kwibhanti ephambili. Ababhali bomsebenzi, oosomazisi ngeenkwenkwezi Avi Leb noAmir Siraj bakholelwa ukuba kunokwenzeka ukuba uninzi lwezinto ezivela kwilifu le-OOST linendawo efanayo.
