Description
Gravitational waves are not a peculiarity of General Relativity (GR). They also arise in an Effective Vector theory of Gravitation (GEV), corresponding to the weak field limit of GR, which predicts in a parameter free way the gravitational quadrupole radiated power. An additional indirect proof of their presence is given in this approach by linear inertial forces, which can be indeed accounted for by gravitational radiation in the accelerated non inertial system. However due to transversality, their interaction with matter predicted by GEV is much smaller than that asserted by GR, thus questioning the possibility of their detection.
