It is shown that, when the length scales are of the order of Plank length, the concept of q unique distance between point cases to exist. It is also shown that the quantum expectations value of the proper length is bounded from below by Plank length in any space-time.enPhysical length scalesQuantum fluctuations of gravityPlanck lengthArticle
