摘要

It is generally assumed that any discrepancy between an object’s inertial and gravitational masses, leading to a violation of the equivalence principle, arises from the nature of its internal constituents and their interactions. We show here that the difference can instead be a function of its distance from a gravitating object. We suggest ways of testing this and provide a covariant framework for our proposal.
