Scientific paper

It is noted that a fundamental weak-field test of a theory of gravitation is that it satisfies the Parameterized Post-Newtonian (PPN) parameters determined by solar system experiments. The production of primordial helium and deuterium in the big bang is seen as a test of a gravitational theory in the strong-field approximation, and it is suggested that this test be used along with the PPN parameters. The test is applied to Rosen's bi-metric theory of gravitation, and for a wide class of models of this theory it is shown that essentially no primordial helium or deuterium is produced.
