Neutrinos: A Fast Trip Here from the Sun
Neutrinos: From the center of the Sun to the Earth
This video covers the 93 million mile journey that a neutrino takes from the center of the Sun to the Earth, and how we detect them. Our initial attempts to detect them were ineffective. There were way too few neutrinos, causing scientists much concern. However later things were made right when it was determined that there were three kinds of neutrinos and our detectors only detected one kind, the electron neutrino.
In addition to the electron neutrino there is a meuon neutrino and a tauon neutrino. These almost massless super fast particles normally zip right through the earth direct from the heart of the sun. It is very difficult to detect them since they pass through all matter easily.
