Around a million, billion neutrinos from the Sun will pass through your body while you read this sentence.
A nutrino is a neutral sub-atomic particle of such small mass that it passes through matter undisturbed.
Its mass has never before been measured accurately and this picture is a device that was set up to detect nutrinos, as VERY ocasionaly they will colide with matter producing energy in the form of light/heat. but this energy is so small that it is virtually undetectable.
Nutrinos are formed from redioactive decay, or nuclear reactions, which is why the sun gives of so many.
The globe of the CERN laboratory shines outside Geneva. A team of experimental physicists there says it has recorded neutrinos traveling 60 nanoseconds faster than the speed of light. (Anja Niedringhaus, Associated Press / September23, 2011)
