Twb tau nyob rau lub Plaub Hlis 1, lub sijhawm ntev tom ntej ntawm kev soj ntsuam pib, tsom mus rau kev tshawb nrhiav thiab kawm cov nthwv dej gravitational - kev hloov pauv hauv thaj av gravitational uas nthuav tawm zoo li nthwv dej.
Cov kws tshaj lij los ntawm LIGO thiab Virgo observatories yuav koom nrog rau theem tshiab ntawm kev ua haujlwm. Cia peb nco qab tias LIGO (Laser Interferometer Gravitational-Wave Observatory) yog laser interferometer gravitational-wave observatory. Nws muaj ob lub blocks, uas nyob hauv Tebchaws Meskas hauv Livingston (Louisiana) thiab Hanford (Washington State) - nyob deb li ntawm 3 txhiab kilometers ntawm ib leeg. Txij li qhov ceev ntawm propagation ntawm gravitational nthwv dej yog supposedly sib npaug zos rau qhov ceev ntawm lub teeb, qhov kev ncua deb no muab ib tug sib txawv ntawm 10 milliseconds, uas tso cai rau peb los txiav txim cov kev taw qhia ntawm qhov chaw ntawm lub kaw lus kaw.
Raws li rau Virgo, qhov no Fabkis-Italian gravitational yoj ntes tau nyob ntawm European Gravitational Observatory (EGO). Nws cov khoom tseem ceeb yog Michelson laser interferometer.
Cov theem tom ntej ntawm kev soj ntsuam yuav kav ib xyoos. Nws tau tshaj tawm tias kev sib txuas lub peev xwm ntawm LIGO thiab Virgo yuav tsim cov cuab yeej rhiab tshaj plaws rau hnub no rau kev kuaj xyuas cov nthwv dej gravitational. Nws xav tias, tshwj xeeb, cov kws tshaj lij yuav tuaj yeem ntes cov cim ntawm hom tshiab los ntawm ntau qhov chaw hauv ntiaj teb.
Peb ntxiv hais tias thawj qhov kev tshawb pom ntawm gravitational nthwv dej tau tshaj tawm thaum Lub Ob Hlis 11, 2016 - lawv qhov chaw yog kev sib koom ua ke ntawm ob qhov dub.
