Neutrinos,Obey Inverse Square Law???

They stream our of the Sun,and the Fermi lab. They jump out of a
neutron the moment it decays into a hydrogen atom.They must go at 'c'
Are they weakining the square of the distance? Do they react with
space. Do they bend with gravity? Do they get to A and B faster than
light? Since the hydrogen atom is 90% of the universe does this mean
the neutrino is the universe's most popular particle wave action.
@What is the reason given they miss atoms even going through LY of
lead? I know they say its because an atom is just about all
space.Could there be yet another answer ?Bert+ Sunbeam
