Dicke was instrumental in proposing extremely sensitive tests of General Relativity. Modern measurements of the various tests, specifically from the Mariner 6 spacecraft in 1969 and the Cassini spacecraft in 2004, show that plain Einsteinian relativity, not the Brans-Dicke theory, agrees with observation<ref name="exper1"/> <ref name="exper2"/> <ref name="exper3"/>. Nevertheless, interest in the Brans-Dicke formulation has recently revived, in the context of dark matter / dark energy investigations. | Dicke was instrumental in proposing extremely sensitive tests of General Relativity.
