I should point out that the positing of irreducible atoms of time and space, while it may solve Zeno’s paradox, introduces a rather serious problem of its own, which I will now endeavor to explain.
If t and d are irreducible atoms of time and space, all ordinarily used units of time and distance must be multiples of t and d. However, it is the ratio of t to d that determines actual speed, not the multiples of t and d. By definition, neither t nor d may be decreased, since they are indivisible. Yet, both may be increased. The important point is this: an increase in d increases speed, but an increase in t lessens speed. Thus, xd/t=d/xt, where x is any number. Therefore, whether d or t is irreducibly multiplied for any given speed, depends entirely on whether the matter is conceptually taken from the point of view of time or distance. This would seem to deny ontological footing to both t and d. Indeed, the ideality of these “atoms” seems inescapable in the light of these observations.
