Quantum mechanics defines physical size as the probability distribution of finding a particle over a small area of space. While electrons and quarks are considered fundamental and do not have physical dimensions by themselves, when the probability distribution is mapped out over a specific area, we get the familiar notion of physical size(keeping in mind that quantum objects do not have well defined boundaries).
Now, if i were able(at least theoretically) to snap a picture of my Civic in exactly one Planck time unit -- 10^-43sec, quantum mechanics predicts that the picture will not contain anything physical(disregrading for this thought experiment the speed of light). While it's relatively certain that the picture will not contain the Civic the camera was pointed at, my question is what 'pattern'(if any) would at least theoretically emerge in the picture taken?
My opinion would be total blackness, since there are no superpositional electrons to reflect light waves back onto the camera lens.
