Abstract

Neutrinos are very peculiar particles. About 610 trillion neutrinos produced by the sun are passing through your body in the second it takes to read this line. If it is night where you are, the neutrinos from the sun are passing through the earth in order to reach you. Because neutrinos have no electric charge and little or no mass, they interact with matter only through the two weakest forces, gravity and the weak interaction. They can pass through solid matter almost as freely as through vacuum, and light years of lead would be needed to absorb them
