Physicists have endeavored for decades to ‘reconcile’ Einstein’s theory of relativity and quantum mechanics, and have failed. This paper reveals that this ‘reconciliation’ should have occurred in the genesis of the two theories, not after the two theories have been developed separately and dogmatized. The two theories developed separately from apparently unrelated problems in the behavior of light, namely: 1. The problem of absolute motion and the speed of light 2. Quantum phenomena. The mainstream view is that these two theories have addressed and solved all the puzzles in physics. However, experimental evidences increasingly challenge and disprove this view. I have been searching for an explanation for each of these apparently unrelated problems, by considering them as separate problems, and have gained crucial insights that have eluded physicists for centuries. However, these insights did not lead to a complete solution of the problems. I was finally able to find the missing link for the quantum puzzles and, profoundly, that turned out to be the missing link for the light speed problem also. The mystery is that nature acts as if it had a foreknowledge of the observer’s motions and actions, which is another way of saying that God exists and directly intervenes in the operation of the universe. In the “Which-Way” and Quantum Experiments, God foresees the experimental set up and, literally, aims each photon accordingly. In the case of light speed experiments, from a foreknowledge of the observer’s motion, God emits a photon from the right point in space and time, with the right velocity of the center of the wave fronts , so that the behavior of light speed in the different experiments and observations is the way it is. One of the long standing puzzles in physics is whether the speed of gravity is finite (light speed) or infinite. Suppose that the Sun disappeared suddenly. Will gravity of the Sun on Earth disappear instantaneously or with the delay of the speed of light? Nature emits zero gravitational field towards the Earth 8.3 minutes before the actual disappearance of the Sun. The zero gravitational field travels at the speed of light and reaches the Earth exactly at the instant the Sun disappears. By apparent violation of causality, nature allows the speed of gravity to be both finite and infinite.
