Understanding Gravity on the Microscopic Level

Authors: Alan M. Kadin

Is there a consistent microscopic foundation for both general relativity and quantum mechanics? Both arose early in the 20th century from a background of classical mechanics and special relativity, but they took quite different turns, leading to seemingly incompatible worldviews. A simple picture is presented that may serve as a bridge between the microscopic quantum and macroscopic gravitational worlds. One may regard a relativistic quantum field as a real physical clock, which slows down as it enters a gravitational potential, providing a simple explanation for gravitational time dilation. This picture leads to a semi-classical Hamiltonian, with an orbital trajectory that is examined in the context of the Parameterized Post-Newtonian (PPN) Approximation. Remarkably, this avoids divergences and singularities, including black holes and event horizons.
