Kuyimitsa pamalo opanda mpweya

Malinga ndi wasayansi James Franson wa pa yunivesite ya Maryland, amene anaphunzira supernova SN 1987A, liwiro la kuwala amachepetsa mu vacuum. Malingaliro ake adasindikizidwa mu nyuzipepala yotchuka ya sayansi "Journal of Physics", kotero ndi yodalirika. Ngati atatsimikiziridwa, zikutanthawuza kusintha kwakukulu kwa sayansi, kuchitira liwiro la kuwala mu vacuum (299792,458 km / h) ngati imodzi mwazinthu zazikulu.

Franson anaona kuti pali kusiyana kwa liwiro limene ma neutrinos ndi photon ochokera ku supernova amatifikira. Neutrinos amafika maola angapo kale kuposa ma photon. Malinga ndi katswiri wa sayansi, izi zikhoza kukhala chifukwa chakuti mu vacuum, ma photons amatha kugawidwa kukhala ma electron ndi positrons, omwe amaphatikizanso kukhala ma photons. Pamene tinthu tating'onoting'ono timapatukana, mphamvu yokoka imatha kuchitika pakati pawo, zomwe zimathandizira kutsika.

Izi zikutanthauza kuti kuwala kumachepetsa kuthamanga komwe kumayenera kuyenda, chifukwa mwayi wotsatizana pang'ono ukuwonjezeka. Pa mtunda woyezedwa mu zaka mamiliyoni a kuwala, kuchedwa kwa kuwala kwa photon kungakhale masabata.
