100cm Mabowo Aakulu Mabere Zidole Zachikondi Zochepa

Zircons ndi mchere wokondedwa kwambiri pakati pa asayansi chifukwa ndi olimba. Izi micrometer kukula makhiristo amatha kupirira nyengo kwa zaka mabiliyoni ambiri kuti asunge zinsinsi za geochemical za kubadwa kwawo. Amagwiranso ma isotopu a uranium kuchokera ku chilengedwe momwe amapangidwira, omwe amagwira ntchito ngati timer yomwe imayambira kuyambira pomwe zirkoni zimawonekera.

Uranium isotopes amawola kukhala mtovu pamlingo wodziwikiratu. Powerengera kuchuluka kwa maatomu amtovu omwe amapanga ndi maatomu a uranium omwe atsala, ofufuza amatha kudziwa kuti padutsa nthawi yochuluka bwanji kuchokera pamene zirkoni zawumitsidwa kuchokera ku zinthu zosungunuka.

Olembawo adafufuza ma zirconi omwe adayikidwa mumwala wamwezi womwe adasonkhanitsidwa pa Apollo 17 mu 1972, ndipo adapanga mapu a 3D a maatomu. Kuwerengera ma isotopu otsogola kudapangitsa zaka 4.46 biliyoni, zaka zakale kwambiri zomwe kutumphuka kwa mwezi kudayamba.

M'badwo uwu udatsimikiziridwa kale ndi ogwira nawo ntchito a Greer motsogozedwa ndi Bidong Zhang ndi Audrey Bouvier mu 2021, koma lipotilo lidayambitsa kukayikira. Otsutsa adanenanso kuti maatomu amtovu amakonda kusamuka ndikupanga matumba okwera kwambiri kapena otsika pamwala wonsewo. Kutengera komwe munthu adayang'ana, panali mwayi woti atha kukumana ndi malo otsogola ogawidwa mosagwirizana ndikusokoneza zaka za zircon.

Kuti achepetse nkhawazi, Bouvier adayandikira gulu la Greer kuti awerengenso maatomu, nthawi ino ndi kafukufuku wa ion womwe ungathe kuyesa thanthwelo pamtunda wapamwamba kwambiri womwe unagwiritsidwa ntchito mu phunziro lapitalo. Kufufuza kwabwinoko kungalole gulu kuti lizindikire zigawo za nanosized za maatomu amtovu olemetsedwa kapena otha, ngati alipo. Koma sanapeze chilichonse.Melina Elden Ring Sex Doll

"Mu zircon iyi, chilichonse chinali chofanana, kotero sitinadandaule nazo," akutero wolemba kafukufuku Philipp Heck, katswiri wa cosmochemist ku Field Museum ndi University of Chicago. Zotsatira zake zidatsimikizira kuti zaka zomwe zidayesedwa kale zaka 4.46 biliyoni zinali zolondola.

"Ndi kafukufuku wabwino kwambiri," akutero Melanie Barboni, katswiri wa geochemist ku Arizona State University yemwe sanachite nawo kafukufukuyu. Barboni adaphunziranso ma isotopu ena mu zirconi za mwezi kuti azindikire kuti mkati mwa mwezi udakhazikika m'magulu osiyanasiyana zaka 4.51 biliyoni zapitazo, gawo lomwe lidatsogola magawo omaliza a kutumphuka omwe adatengedwa mu kafukufuku watsopano.

Barboni akuti kafukufuku watsopanoyu ndi wogwirizana ndi zomwe wapeza. “Mapepala ambiri amanena kuti mwezi unapangidwa mochedwa kwambiri, mwachitsanzo, zaka 4.3 biliyoni,” akuwonjezera motero. "Zikuwoneka kuti sizingatheke ndi datayo."
