Based on the fact that torsion is related to fundamental unit of spin h,defects in space-time topology should occur in multiples of Planck length that follows from the intrinsic defect built into the structure of space-time,implying a minimal fundamental length which,in turn,implies a maximal curvature.This results has some physical consequences:entropy do not become infinite as the collapsing object approaches the Schwarzschild radius and moreover we have also a minimal mass(≠0 and =Mpl) of black holes that could form in the early universe or survive as a remnant in the evaporation of larger black holes.
