Abstract

Aims. We investigate in detail two physical properties of the metric theory developed by Sobouti (2007, A&A, 464, 921). We first look for the possibility of producing gravitational waves which travel at the speed of light. We then check the possibility of producing extra bending in the lenses produced by the theory.
