Qee cov txheej txheem tsis tuaj yeem tsim dua tshiab hauv cov chaw kuaj mob, tab sis cov kws tshawb fawb tuaj yeem tsim cov txheej txheem rau kev nkag siab zoo ntawm lub cev thiab lwm yam tshwm sim. Xav pom supernovae tawg? Mus ntsib Georgia lub koom haum thev naus laus zis, lawv nyuam qhuav pib "tshuab" los simulate supernova tawg.
Georgia Tech cov kws tshawb fawb ib lub chaw kuaj kev teeb tsa rau txoj kev tshawb fawb txog kev nthuav tawm tawg ntawm kev sib xyaw ntawm lub teeb thiab hnyav gases. Cov txheej txheem zoo sib xws nrog supernova tawg. Nuclear fusion nyob rau hauv lub cores ntawm cov hnub qub ploj mus, thiab lub ntiajteb txawj nqus yeej kev sib ntaus sib tua nrog cov buoyant rog ntawm fusion. Lub plhaub roj ntawm cov hnub qub tawg yog compressed thiab ib qho supernova tawg tshwm sim nrog kev tawm tsam ntawm cov pa roj thiab teeb meem. Raws li qhov tshwm sim, zoo nkauj nebulae tshwm nyob rau saum ntuj, qhov tshwm sim ntawm qhov tshwm sim ntawm kev sib kis ntawm cov roj sib txawv ntawm qhov sib txawv ntawm lub hnub qub neutron lossis lub qhov dub - txhua yam uas tseem tshuav ntawm lub hnub qub.
Kev teeb tsa lub chaw kuaj sim simulates cov txheej txheem ntawm kev tawg hauv ib qho me me ntawm lub hnub qub qauv. Lub installation zoo ib yam li ib daim ntawm pizza, 1,8 m siab thiab mus txog 1,2 m dav. Nyob rau hauv nruab nrab ntawm lub installation muaj ib lub qhov rais pob tshab los ntawm cov txheej txheem yog kaw siv high-speed photography. Qhov kev teeb tsa tau ntim nrog cov roj sib txawv ntawm qhov sib txawv, zoo ib yam hauv cov khoom sib xyaw thiab lub xeev rau cov uas sau lub hnab ntawv ntawm cov hnub qub. Qhov tawg ntawm cov tub ntxhais yog simulated los ntawm ob qho khoom tawg: lub ntsiab yog hexogen thiab, raws li ib tug detonator, pentaerythritol tetranitrate.
Lub detonation ntawm explosives pushes low-lying heavy gases los ntawm cov khaubncaws sab nraud povtseg ntawm tsawg hnyav gases thiab bizarrely swirls roj sib tov. Raws li cov kws tshawb fawb, qhov no tsis yog tsuas yog zoo nkauj xwb, tab sis kuj tseem siv tau los ntsuas qhov ceev ntawm kev txav ntawm cov pa roj ntawm qhov sib txawv.
Kev sim hauv chav sim nrog "supernova tshuab" tuaj yeem muab cov ntaub ntawv astronomers kom raug xam ntau dua qhov tsim ntawm cosmic khoom xws li nebulae. Thaum kawg, kev nkag siab qee qhov tshwm sim tuaj yeem muab cov lus qhia los tsim lub fusion reactor hauv ntiaj teb.
