    Quarks and neutrinos (please correct me if I'm wrong here!) are the only particles known to oscillate from one form (flavour) to another.

    Is it possible that they interact? Quarks being static, neutrinos being transient, is it also possible that they exchange information? Hypothetically speaking, of course... I know of no experiments currently tackling it.

    I appreciate this is a wild-card kind of question, but it is one I have pondered for a number of years.

    Neutrino doesn't interact with any other particle, hence the name.

    Here is an article from the Super-K experiment detailing the history of neutrino discoveries http://www.ps.uci.edu/~superk/neutrino.html

    Since neutrinos were the predominant particle during the early history of the Universe, they are clearly important. It cannot be said definitively that they do not interact with any other particle. Their interactions have made the research on them possible and we still know very little about their nature. They have mass, so they have substance, and their forrm (being largely unknown) could have any number of effects on other forms which we do not yet understand.

    These are the speculations I am hoping to draw from this thread, for there must be many people here who have considered the same question.

    Quarks and neutrinos interact indirectly through the weak interaction, which is mediated by by the W and Z bosons. https://en.wikipedia.org/wiki/Weak_interaction

    I don't know what you mean by "exchange information", can you clarify what you are thinking of?
    You can do everything right, strictly according to procedure, on the ocean and it'll still kill you, but if you're a good navigator at least you'll know where you were when you died.

    As you said, 'indirectly via the weak interaction' - a hint at something deeper? Gauge invariance https://physics.stackexchange.com/qu...uge-invariance suggests degrees of freedom which don't have measurable parameters - could it be that information (in our case, of solar origin) reaches the planetary material (quarks) via neutrinos? And if so - bearing in mind that this is a purely investigative question - the oscillatory qualities of both neutrino and quark could have a greater significance than has been considered to date.

    As there is no evidence that neutrinos carry information about their source, and pretty much all of them pass through the Earth as if it weren't there, this seems an implausible hypothesis. But feel free to provide some evidence of this "greater significance". (Or just stop posting made-up nonsense.)

    This post re-presented itself on my tablet so I posted it again erronously, but it is a serious question inviting serious answers. There is room for exploration of such topics as they have potentially serious implicatons.

    As there is no evidence for any such effect, and no known mechanism for it, I'm not sure what sort of "serious discussion" you expect.

    You seem to think that any random thing that occurs to you is worthy of serious discussion. So far, none of it has been.

    Strangely sad, this last reply, sarcasm being the lowest form of wit and all, but then, each to their own I suppose.

    Triplicate oscillation appears to be a quality shared by only two particles, neutrino and quark, so the question is, [I]could[I] there be an element of interaction between them, given this relative quality? Gluons are often said to be 'virtual particles' so even less is known about those - could there be an information exchange between gluons and neutrinos which then affects the oscillation of the quark? I appreciate that experimentation on these scales is virtually impossible, so there can as yet be no evidence, but speculation and ideas are just as useful in discussion, and I promise you, Strange, this is one of the less random things to have occurred to me over the years.

    Only neutrinos oscillate between three types. Quarks can change from one type to another by means of the weak interaction; this means other particles are involved.

    Gluons are often said to be 'virtual particles' so even less is known about those
    It doesn't mean that, at all. All forces are mediated by virtual particles (which are not really particles at all). So, for example, magnetism is mediated by virtual photons - that doesn't mean we know less about photons.

    I appreciate that experimentation on these scales is virtually impossible, so there can as yet be no evidence
    Experimentation on these scales is entirely possible, for example at the LHC. That is how so much is known about quarks, gluons, W and Z bosons, etc.
