(PhysOrg.com) -- While physicist Robert Dicke is probably most famous for his work on the cosmic microwave background (CMB) – and being "scooped" while attempting to be the first to detect it – he also performed ...
Space is a violent place. If a star explodes or black holes collide anywhere in our part of the Milky Way, they'd give off colossal blasts of lethal gamma-rays, X-rays and cosmic rays and it's perfectly reasonable to expect ...
