The scalar-tensor (ST) gravitational theory of Mbelek and Lachièze-Rey (MLR), allows electromagnetic (EM) fields to modify the space-time metric far more strongly than predicted by General Relativity and standard ST theories.
The theory was applied in cosmological and galactic contexts, and it was used to explain the discordant measurements of Newton gravitational constant as due to the effect of the earth's magnetic field. It was further shown that a ST theory of the MLR type could explain the unusual forces on asymmetric resonant cavities reported at that time. However, in the derivation of the equations from the action principle some inconsistencies were observed, and also the forces obtained, after reconsideration of the experiments originally reported and new results were too high.
