If we take a segment of length, we can divide it in half. We can take one of the remaining halves, and we can divide it in half again. We naturally assume that this can go on forever. We assume that no matter how small a length we end up dealing with, we can always - at least conceptually - divide any remainder in half. It turns out that this is not true. There is a length known as the Planck length, 10-33 centimeters, that is indivisible. At that point is loses locality.. so its either there or not.. so to speak it becomes a 1 or a none if you will. A digital signal is a 1 or a 0... So is it completely wrong to say all matter is digital?
