100cm waaweyn oo naaska ah mini jecel caruusadaha

Zirrons waa macdanta ay ugu jecel yihiin saynisyahanada maxaa yeelay way adag yihiin. Cabirradan milica Kiristaalku wuxuu u hor joogsan karaa cimilo badan oo ku saabsan balaayiin sanadood si loo ilaaliyo sirta hubka ah ee dhalashadooda. Waxay sidoo kale ku qabsadaan uranium-ka is-ka-baxa ee deegaanka markay sameeyaan, kuwaas oo u adeegaya sidii jadwal ka bilaabmaya xilligan Zirtrons Crystallizize.ebony galmada Carshiga

Uranium-ka ayaa u qalqal geliya hogaaminta heerarka saadaalinta. Adoo tirinaya tirada atomyada hogaanka ee qaabka iyo atomyada uranium-ka ee hadhay, cilmi-baarayaashu waxay ka shaqeyn karaan inta waqti ee soo maray maadaama zirts ay ka adkaatay in la shubo sheyga la shubay.

Qoradaha daraasadda ayaa baaray in zirgamayaasha lagu soo rogay muunad dhagax dhagax ah oo laga soo ururiyey inta lagu gudajiray Apollo 17 sanadkii 1972, waxayna dhigtay khariidad 3D ah oo ah atomyada. Tijaabinta isotopers hogaanka ayaa sababay in da'deedu tahay 4.46 bilyan sano, da'da ugu da'da weyn ee qaab dhismeedka dayaxa ah weli.

Da'daas waxaa horay loo go'aamiyay iskaashiga GREER ee uu hogaaminayo Binong Zhang iyo Audrey Bouvier sanadkii 2021, laakiin warbixintu waxay gashay shaki. Dadka dhaleeceeya waxay tilmaameen xaqiiqda ah in hogaaminta atoms ay u egtahay inay u haajiraan inay sameeyaan jeebado ka mid ah uruurinta sare ama hoose ee dhagaxa dhagaxa ah. Waxay kuxirantahay halka qof loo eegay, waxaa jiray fursad ay ku soo bandhigi karaan goobahan sunta rasaasta ee aan sinnayn u qaybin oo loo qaybiyo da 'da' yarta.

Si loo helo walaacyadan, Bouvier wuxuu u soo dhowaaday kooxda GREER si uu u tiriyo atomyada mar labaad, waqtigan iyadoo baaritaan lagu qaadanayo qaraarka ugu sarreeya ee loo adeegsaday daraasaddii hore ee loo adeegsaday daraasadda hore. Baadhitaan wanaagsan ayaa u oggolaanaya kooxda inay aqoonsadaan gobollada nanosied ee atomooyin hogaan ah oo hodan ah ama dhameystiran, haddii ay jiraan. Laakiin waxay heleen no.melina Elen gen gen gell galmada

"Zokonn gudaheeda, wax walba waxay ahaayeen isku mid, sidaa darteed xitaa ma ahan inaan ka walwalo arrintaas," ayuu yidhi qoraaga Daraasad Philipp Heck, oo ah Cosmochemist-ka Matxafka garoonka iyo Jaamacadda Chicago. Natiijadu waxay xaqiijisay in markii hore loo cabbiray oo ah 4.46 bilyan sano ay sax ahayd.

"Waa waxbarasho aad u fiican," ayuu yidhi Melanie Barboni, oo ah Geocchemist-ka oo ka dhacay jaamacadda Armona ee Arizona oo aan ku lug lahayn cilmi-baarista. Barboni wuxuu bartay cilmiga kale ee suumanka ee yar yar si uu u ogaado in Dayashadu ay markii ugu horreysay ee ku taal lakab kala duwan oo kala duwan 4.51 bilyan sano ka hor intay ka hor mareennada ah ee lagu qabtay daraasadda cusub.

Barboni wuxuu leeyahay cilmi baarista cusub waxay la jaan qaadanaysaa natiijooyinkeeda. "Waraaqo badan ayaa soo jeedinaya in dayaxu uu sameeyay wax badan intaas ka dib taas, 4.3 bilyan sano, tusaale ahaan," ayay raacisay. "Taasi waxay si cad u suurta gal tahay suuragal xogtaas."
