    Hello,

    A couple questions on neutrinos:

    1) do they travel like photons? That is to say, as waves?

    2) do they influence/interact with each other like charged particles do? For example, two electrons will repel each other due to their mutual negative charge. Do neutrinos affect each other in some way like this?

    All particles (photons, electrons, neutrinos) can be treated as waves, when appropriate, or as particles, when appropriate. It is more a function of what you are measuring as to which view is more appropriate; e.g. energy of a particle is equivalent to frequency of the waves.

    2) do they influence/interact with each other like charged particles do? For example, two electrons will repel each other due to their mutual negative charge. Do neutrinos affect each other in some way like this?
    Neutrinos do not interact like electrons because they have no charge. In fact they hardly interact with anything at all. This is why they can travel through solid rock - in fact a neutrino could travel through light-years of lead without noticing.

    Quite. This is what makes them so hard to detect. In the recent "are neutrinos faster than light?" experiment, they generated something like 100,000,000,000,000,000,000 neutrinos and detected 16000.
