Re: One of these things is not the same as the other...
Umm. IIRC light can be refracted by gravitational masses, but neutrinos...what path do they take?
Well they have mass so should also be bent by strong gravitational fields en passant, but to the same extent?
My A-level physics gives up at this point.
Also light slows down when passing through matter, but neutrinos do not I believe?
