Quantum gravity and the zero point length

Abstract In this paper, we present an overview of some the existing issues research in quantum gravity. We also introduce basic ideas that led Padmanabhan to consider a duality property path integrals. Such is consistent with T-duality string theory. More importantly, integral discloses universal feature any geometry, namely existence zero point length $$L_0$$ L 0 . comment about recent developments aiming expose effects strong electrodynamics and black holes. There are reasons believe main characters phenomenology gravity may be described by means single parameter like
