Interestingly, the (so-called) "many worlds" interpretation of quantum theory
both supports and denies the existence of physical randomness.  It supports
it in that its (appropriate) observables are indistinguishable from random,
by you, the observer there.  But denies it in that all possible outcomes
(along with all possible sequents and parallel cases) do actually really
physically occur, here in our own piece of space-time, but indetectable
by us once sufficiently de-cohered.  And OC there are other versions of
all of "us" in those other "worlds" who see it exactly the reverse.

Whether or how this blends in with whatever Kreinovich and others adduce
to be the effect of physical randomness on abstract math, is unclear,
but might well lead to some interesting insights.
