Theoretical frameworks for testing relativistic gravity. 5. Post-Newtonian limit of Rosen's theory
The post-Newtonian limit of Rosen's theory of gravity was evaluated, and was shown to be identical to that of general relativity, except for the parametrized post-Newtonian (PPN) parameter alpha2 (which is related to the difference in propagation speeds for gravitational and electromagnetic waves). Both the value of alpha2 and the value of the Newtonian gravitational constant depend on the present cosmological structure of the universe. If the cosmological structure has a specific (but presumably special) form, the Newtonian gravitational constant assumes its current value, alpha 2 is zero, the post-Newtonian limit of Rosen's theory is identical to that of general relativity, and standard solar system experiments cannot distinguish between the two theories.
