Ghost Particles - New Limits On Extremely Rare Neutrino Decay

Neutrinos are the second most abundant particles in the Universe, after photons, but when it comes to being elusive they can compete with anything. That's due to their having extremely weak interactions with all other particles, which leads to them being called  'ghost particles’. Neutrinos are invisible but could carry as much mass as all other known forms of matter, traveling almost at the speed of light over fantastic distances. Their tiny masses have  important consequences for the structures in the Universe and they are the driving element in the explosion of Supernovae. read more
