Neutrinos very rarely interact with anything and thus are very hardto detect. About 10^14 neutrinos from the sun pass through yourbody every second, even at midnight (the neutrinos easily gothrough the earth), but this is of no concern since only one a dayinteracts with any quark or lepton in your body. In fact, aneutrino would have to pass through several thousand light years ofsolid lead before it would have a 50-50 chance of being absorbed.Given the information in C1.5, see if you can explain why neutrinosso rarely interact with normal matter.\

C1.5 describes interactions (Gravitational, Electromagnetic, Weaknuclear, and strong nuclear), and also includes a table aboutLeptons and Quarks.

I was thinking the answer was that Neutrinos don't react withmatter very frequently because they have little to no mass, and nocharge - thus they can only participate in weak nuclearinteractions or gravitational interactions which are extremelyweak.

Is this the correct line of thinking?
