Neutrino

Neutrino : is a type of strange, weird, tiny, energetic particle, with neither mass nor electric charge, it is virtually an undetectable particle and one of the most illusive in the universe.

Scientists now believe that neutrinos fill our universe and rough calculations suggest that a hundred trillion neutrinos pass through our bodies every second. Some can even pass unchanged pass right through the Earth and through giant clouds of interstellar gas and dust, without leaving a trace.

This unique ability allows neutrinos to carry messages from the far reaches of the universe. Indeed some neutrinos are so fantastically energetic, 'they carry a bigger punch than even the most intense gamma ray.' For this reason it is thought that neutrinos may originate from places such as neutron stars, active galactic centers and exploding stars, or supernovas. Some scientists even believe that the lower-energy neutrinos may comprise a large proportion of the mass in the universe.
