Fluctuational Spacetime

Abstract

Newton's action at a distance gravitational law and Coulomb's action at a distance electrostatic law had to be reexamined in the light of field theories which originated from Maxwell's electrodynamics. These ideas were further modified with the advent of Quantum Theory, even though the differentiable spacetime manifold of Classical Physics was retained. More recent approaches in unifying gravitation with the other fundamental interactions has lead to a spacetime that is not smooth. In this light we examine the nature of spacetime, taking into consideration the role of fluctuations.
