anonymous, the rate of change in amplitude at a location depends only on the derivatives at that location (and the derivative of a function at a point depends only on the values near that point).
Eliezer, I am on the whole inclined to agree with Psy-Kosh, but I sometimes suspect (wild unsupported speculation) that perhaps a locality rule is fundamental and spacetime itself is not, but derived from the locality.
