If neutrinos don't interact with anything and they just pass straight through everything then does that mean that they just last forever or what? What happens to them?

Hi Yunus,

Your premise that neutrinos don't interact with anything is not correct.  Although their interaction probability is quite small it is not zero.  In fact many experiments at high energy accelerators such as the Tevatron at Fermilab and the LHC at CERN study these interactions.  

I suggest that you take a look at for an update on the wily neutrino.
