Nyob rau hauv txoj kev xav ntawm quantum gravity, lub graviton yog lub hypothetical quantum ntawm lub ntiajteb txawj nqus, ib qho me me uas nruab nrab lub zog ntawm kev sib cuam tshuam ntawm gravitational. … Nyob rau hauv txoj hlua txoj hlua, ntseeg tau tias yog ib txoj kev xav zoo ib yam ntawm quantum gravity, lub graviton yog lub xeev tsis muaj zog ntawm txoj hlua tseem ceeb.
Dab tsi yog quantum gravity hauv cov ntsiab lus yooj yim?
Quantum gravity yog tag nrho cov ntsiab lus rau txoj kev xav uas sim ua kom sib koom ua ke lub ntiajteb txawj nqus nrog rau lwm qhov tseem ceeb ntawm physics (uas twb tau koom ua ke lawm). Nws feem ntau posits lub theoretical qhov chaw, graviton, uas yog ib tug virtual particle uas mediates lub gravitational quab yuam.
Puas yog quantum gravity tiag?
Muaj ntau lub tswv yim quantum gravity theories. Tam sim no, tseem tsis tau ua tiav quantum txoj kev xav ntawm lub ntiajteb txawj nqus, thiab cov qauv sib tw tseem yuav tsum tau kov yeej cov teeb meem tseem ceeb thiab kev xav.
Dab tsi yog graviton hauv physics?
Graviton, postulated quantum uas xav tias yog tus cab kuj ntawm lub gravitational tebNws yog qhov sib piv rau qhov zoo-tsim photon ntawm electromagnetic teb. Gravitons, zoo li photons, yuav tsis loj, cov khoom siv hluav taws xob tsis muaj hluav taws xob taug kev ntawm lub teeb nrawm.
Lawv puas pom lub graviton?
Hmoov tsis zoo, ob qho tib si tsis zoo. Ib qho laj thawj ntawm qhov ntawd: thaum cov kws tshawb fawb paub txog cov khoom cuam tshuam nrog lub zog muaj zog, tsis muaj zog thiab hluav taws xob, lawv tseem tsis tau pom ib qho me me ntawm lub ntiajteb txawj nqus, lossis graviton.
