Superposition in Modern Classical Mechanics and General Relativity

Abstract

For evaluating the macroscopicity of superposition states in classic mechanical systems, we suggest an objective measure that is accessible through experimentation. One can measure the level of macroscopicity attained in various experiments based on the observable results of a minimum, macrorealist extension of modern classical mechanics. Numerous experiments have widely and independently supported general relativity. The interaction of the two theories has never been tested, though, as all tests that examined how gravity affects classic mechanical systems are compatible with Newtonian, non-relativistic gravity.
