Which may mean that we just haven't found a "complete" mathematical expression for it. You won't get me denying JC Maxell's work, though.
It isn't just light though. It is *all* quantum particles. We have seen interference effects in *atoms*.
And it isn't just that we see these effects at different times. If you turn down the intensity of the incoming light in the double-slit experiment, you will detect individual photons *and* get an interference pattern building up over time.
The mathematical description we have is quantum mechanics. And the claims that it is incomplete (like those from Einstein) have been observationally shown to be flawed (EPR and Arrow's experiment).
The quantum world simply does not act via classical ideas of 'matter' or 'causality'. Thinking of photons (or electrons, or neutrons) as little balls flying around is just not a good image: it is classical.
