Document Summary
Neutrinos are produced in the weak interaction , for example . Detecting neutrinos requires a different kind of detector. This works out to about 330 neutrinos in every centimeter cubed of the. By comparison there are about . 0000005 protons per centimeter cubed in universe the universe. Your own body emits about 340 million neutrinos per day from 40k. Neutrinos don"t do much when passing through matter, thus it is very difficult to observe neutrinos. Neutrinos are observed by detecting the product of their interaction with matter. Neutrinos reveal information about the sun"s core- and have surprises of their own. Neutrinos emitted in thermonuclear reactions in the sun"s core were detected, but. Recent neutrino experiments explain why this is so smaller numbers ( ) than expected. Galileo tried unsuccessfully to determine the speed of light using an assistant with a lantern on a distant hilltop.
