What is the Velocity of Gravitational Waves?

We present a new field theory of gravity. It incorporates a great part of General Relativity (GR) and can be interpreted in the standard geometrical way like GR as far as the interaction of matter to gravity is concerned. However, it differs from GR when treating gravity to gravity interaction. The most crucial distinction concerns the velocity of propagation of gravitational waves. Since there is a large expectation that the detection of gravitational waves will occur in the near future the question of which theory describes Nature better will probably be settled soon.
