  We suggest that a satellite with a stable atomic clock on board be sent
through the Earth-Sun gravitational saddle point to experimentally determine
whether Nature prefers static solutions of the field equations of General
Relativity, such as the standard Schwarzschild solution, or whether Nature
prefers equivalent non-static solutions. This is a test of the boundary
conditions of General Relativity rather than of the field equations. The
fractional difference in clock rates between the two possibilities is a part in
a hundred million. This is a large and easily measurable effect.
