Expansion of space in static solutions of general relativity
An interpretation of general relativity is developed in which space expands with gravitational potential in static solutions. This approach is applied to the Schwarzschild and Friedmann-Robertson-Walker metrics. To determine how space expands or contracts, a “physicality conjecture”
is introduced that requires selection of a preferred metric for any boundary condition. This view is incompatible with the prevailing interpretation of general covariance. It is shown that a simple modification to the traditional interpretation of relativity can incorporate the postulated
expansion of space. At present, no known experiment can distinguish between the traditional and proposed interpretations.
