The Novello-De Lorenci-Luciane (NDL) field theory of gravitation predicts that gravitational waves (GWs) follow geodesics of a modified (effective) geometry with a speed lower than the velocity of light. The theory also demonstrates that GWs exhibit the phenomenon of birefringence, formerly believed to be exclusive of electromagnetic waves. Here prospective astrophysical tests of these predictions are proposed. We point out that future measurements of gravitational waves in coincidence with a non-gravitational process such as a neutrino burst, and more likely an accompanying burst of gamma-rays, may lead to discriminate among all the existing theories of gravity. We also point out that prospective observations of microlensing events of GWs by galactic black holes (MACHOs Collaboration's) may prove useful in this respect.
