This sentence is also wrong in mathematics! There is indeed a distance between any infinitely approaching zero bullets, to be exact, infinitely many, which is called infinitesimal in higher mathematics, but the accumulation of infinitesimal is not necessarily infinitesimal, that is, the sum of all infinitely approaching zero distances is not infinitesimal distance! For example, the distance from 0 to 1 is 1, which is the accumulation of the lengths of all points between 0 and 1, but in fact these points have no length. Philosophically, quantitative change causes qualitative change!
