**Abstract:**

The paper presents a physical model in which mass fields and momentum fields mediate gravitational interactions. The model addresses: Gravitational interaction between masses, between mass and energy, and between photons; Gravity’s effect on spectral lines, time periods of atomic clocks, and lengths of material rods; Gravitational radiation; Mercury’s orbital precession rate; and the Pioneer effect. It reflects upon time. The model rediscovers the initial predictions of general relativity. It makes new predictions: Gravitational interactions can be attractive, repulsive, or zero; Photons gravitationally interact albeit negligibly; the Classical gravitational constant is not a constant; and Accelerating masses generate gravitational radiation, which has a four-lobed quadrupole pattern and propagates at less than the speed of light. The paper puts forward specific suggestions for measuring the model’s constants, including the speed of gravitational radiation, and for detecting gravitational radiation.
