Commissar SFLUFAN Posted July 13, 2018 Share Posted July 13, 2018 In a cosmic first, scientists detect ‘ghost particles’ from a distant galaxy When the sun was young and faint and the Earth was barely formed, a gigantic black hole in a distant, brilliant galaxy spat out a powerful jet of radiation. That jet contained neutrinos — subatomic particles so tiny and difficult to detect they are nicknamed “ghost particles.” Four billion years later, at Earth’s South Pole, 5,160 sensors buried more than a mile beneath the ice detected a single ghostly neutrino as it interacted with an atom. Scientists then traced the particle back to the galaxy that created it. Quote Link to comment Share on other sites More sharing options...
