[The Epoch Times, April 10, 2024] (Lolembedwa ndi mtolankhani wa Epoch Times, Li Yan) Asayansi anachenjeza m’kafukufuku watsopano kuti pulaneti lathu lidzamezedwa ndi dzuŵa lomwe likukula. Panthawi imodzimodziyo, mapulaneti ena ozungulira dzuwa "adzaphwanyidwa kukhala fumbi." Mwamwayi, palibe chifukwa chochitira mantha. Asayansi amati izi zitha kuchitika pafupifupi zaka 6 biliyoni.
Malinga ndi lipoti la "Daily Mail", kafukufuku wochokera ku yunivesite ya Warwick ku UK anafotokoza kuti nyenyezi ngati dzuŵa zimafinya maatomu a haidrojeni mu helium mothandizidwa ndi mphamvu yokoka yaikulu, motero imatulutsa kuwala ndi kutentha. Komabe, nyenyezi zonse zili ndi hydrogen yambiri. Mafuta a haidrojeni akayamba kutha, mphamvu zimene zimachititsa kuti nyenyeziyo isasunthike, zimachotsedwa.
Kuyambira m’zaka pafupifupi mabiliyoni 5, dzuŵa lathu lidzapsereza hydrogen yomwe ili m’kati mwake ndiyeno idzayamba kuyaka helium m’zigawo zake zakunja, kutukuka kuŵirikiza kuŵirikiza ka 200 kukula kwake koyambirira.
Nyenyezi zina zazikuluzikulu zimaphulika ngati supernova zikakomoka, koma zathu zimakhala zazing'ono moti zimatha kufa mwachindunji pambuyo pomeza mafuta ake omaliza.
Izi zidzachitika pafupifupi zaka 6 biliyoni. Panthawiyo, zotsalira zowundana kwambiri za pakatikati pa Dzuwa ndizomwe zidzasiyidwe, kukhala nyenyezi yaying'ono yoyera yomwe imatulutsa kutentha kotsalira pamene ikuzizira pang'onopang'ono. Itha kukhala yayikulu ngati Dzuwa, koma osati yayikulu kuposa Dziko Lapansi, motero ili ndi gawo lamphamvu yokoka.
Pulofesa Boris Gaensicke wa ku yunivesite ya Warwick anati: “Chomvetsa chisoni n’chakuti Dziko lapansi likhoza kumezedwa ndi dzuŵa lomwe likukulirakulirali lisanasinthe n’kukhala duwa loyera.
Komabe, sizidziwika bwino zomwe zimachitika kumadera ena onse ozungulira dzuwa dzuŵa likasandulika kukhala loyera.
Tsoka losadziwika bwino
Mu kafukufuku wawo watsopano, ofufuzawo adawunika kuwala kwa ma dwarfs atatu oyera pazaka 17.
Poona kukwera ndi kutsika kwa kuwala, asayansi amatha kudziwa nthawi yomwe zinthu zimadutsa kutsogolo kwa dzuwa ndi mtundu wa zinthu zomwe ziri.
Kwa nyenyezi zambiri, kusintha kwa kuwala kapena kayendedwe ndikodziwikiratu kwambiri chifukwa planeti limayenda mokhazikika m'njira yake.
Koma pozungulira ma dwarfs oyera, ofufuza adapeza kuti zodutsa zimakhala zosokoneza komanso zosakhazikika. Izi zikusonyeza kuti tsogolo la zinthu zozungulira white dwarfs zikhoza kukhala zoopsa kwambiri.
Mapulaneti, ma asteroids ndi ma satellites omwe amayandikira pakati pa nyenyezi yofiira yoyera adzang'ambika chifukwa cha mphamvu yokoka. Pambuyo pake, zidutswazo zimaphwanyidwa kukhala fumbi pamene zikuwombana.
Fumbi limeneli likupitirizabe kuzungulira nyenyezi yakufayo mpaka kenako n’kusakira m’chilengedwe chonse.
M’dongosolo lathu la dzuŵa, ichi chidzakhala tsogolo la zinthu zambiri zotsalira zomwe sizimezedwa kapena kuwonongedwa ndi kufutukuka kwa dzuŵa. Komabe, kusadziŵika kwa machitidwe a white dwarf kumapangitsa kuwaphunzira kukhala kovuta kwambiri.
Gaineske ananena kuti: “N’zomvetsa chisoni kuti tikupeza zidutswa za nyenyezi, mwezi ngakhalenso mapulaneti amene akudutsa m’maola ochepa chabe. "Koma kafukufuku wathu akuwonetsa kuti machitidwewa ndi Makhalidwe amatha kusinthika mwachangu."
"Kusadziŵika bwino kwa maulendowa kumachititsa misala akatswiri a zakuthambo-mphindi imodzi iwo ali pamenepo, yotsatira achoka. Ichi ndi chisonyezero cha chipwirikiti cha chilengedwe chomwe iwo ali."
Mtengo wa magawo Xuange Electronicsyadzipereka kukhala mtsogoleri wotsogola padziko lonse lapansi wa zigawo za maginito, osapereka zinthu zokhazokha komanso ntchito zopangira makonda kuti makasitomala athe kupeza zotsatira zabwino. Zida zonse zomwe zimagwiritsidwa ntchito pazinthuzo zadutsa chiphaso cha UL / CE ndipo zayesedwa kwambiri ndikuwunika musanatumizidwe kuti zitsimikizire kukhazikika komanso kutsimikizira makasitomala. Ndi bwenzi lodalirika lanthawi yayitali la opanga magetsi odziwika bwino!
Pamafunso azinthu, chonde onanitsamba mankhwala, nanunso mwalandiridwaLumikizanani nafekudzera muzomwe zili pansipa, tidzakuyankhani mkati mwa 24.
