Abstract: By introducing torsion in general relativity - that is physically considering the effect of the spin and linking the torsion to defects in the space-time topology - a minimum unit of time can be obtained. In this context the possibility exists of identifying the defects in space-time topology induced by torsion as behaving like a string so that the minimum length, derived by treating the spin as an extra dimension, is related with string tension. Physical implications are considered for field theory (the divergence of self-energy integral is eliminated without introducing any ad hoc cut-off), particle decay, evaporation of black holes, and information theory.
