I mean continuous in the calculus sense, as in it doesn't have discontinuities, not as in continuous VS discrete. > Given that physics seems to be discrete at the low level, this suggests to me they don't, but I don't know enough to be sure. This is a misunderstanding of quantum mechanics. Only certain specific quantities come in discrete quanta (spin, charge, certain energy levels, etc). Other physical quantities are very much continuous - notably time and space. In fact, much of the mathematics of QM is not discretizable, it won't work if you try to make time or space discrete.
