Maximal Proper Acceleration and the Quantum-to-Classical Transition

I first review the physical basis for the universal maximal proper acceleration. Next, I introduce a new formulation for a relativistic scalar quantum field which generalizes the canonical theory to include the limiting proper acceleration. This field is then used to construct a simple model of an uncorrelated many-body system. I next argue that for a macroscopic object consisting of more than Avogadro's number of atoms, any supposed quantum state of the object is negligibly small, so that for all practical purposes, the object is best described by classical mechanics. Thus, a new explanation is offered for the quantum-to-classical transition and the absence of quantum superposition of macroscopic objects in the everyday world.
