    M-theory and dark matter

    Just a quick question, what does M-theory have to say about dark matter? Is it possible that what we are calling dark matter is actually a sort of mass shadow, that is gravity of mass in an adjacent brane leaking over into our brane? If not, what would be the apparent effect of gravity leaking into our brane from other ones?

    I don't think there's much of a direct link, but most versions of M theory posit the existence of a pretty large array of particles that we do not see, presumably because they interact only fairly weakly with normal matter. So it's easy to imagine that some or all of those particles could easily turn out to be the primary constituent of dark matter.
    Conserve energy. Commute with the Hamiltonian.
