Assuming that a planck length is the smallest unit of distance, I propose this: Assume there was a circle of radius r and had an area of A. If I would increase this circle's area by 1 planck length^2, would the radius change? The radius would theoretically change by less than a planck length, but would the radius actually change? Another would be if I increased this circle's diameter by 1 planck length. Would the radius increase? Are these true paradoxes, something that just happens at this level or do they not hold any water?
