Summary: One of the fundamental predictions of the Big Bang is the present day existence of relic neutrino produced less than one second after the event. Join Christopher Tully, professor of physics at Princeton University, as he discusses a new experiment called PTOLEMY (Princeton Tritium Observatory for Light, Early-Universe, Massive-Neutrino Yield) and its potential to challenge this core prediction, as well as uncover new properties of neutrinos themselves. This lecture took place at the Hayden Planetarium on June 8, 2015.
