Neutrinos—The Ghost Particle


A neutrino is a subatomic particle that found its similarities with that of an electron. But unlike electron, it has no electrical charge and negligibly small mass, which can also be considered zero. It is one of the fundamental particles which make up the entire universe.

Neutrinos are the most abundant particles in the universe still they are difficult to detect because they interact with matter in least possible circumstances.

They are almost nothing at all, because they have almost no mass and no electric charge. They are just little wisps of almost nothing because of which they are also referred to as ghost particles.
