I have been wondering why photons can't go through matter and electromagnetic fields mostly unaffected while neutrinos can. Neither of them have an electric charge as a particle, and the basic description I see about neutrinos is always that "they are unaffected because they have zero electric charge". I understand, on a basic level, that the photons are gauge bosons and they mediate the electromagnetic force, but I could not quite find a clear description as to how this leads to EM fields interacting with photons but not interacting with neutrinos. Any (also short) replies or links will be appreciated. Thanks in advance.
