One of the yet unsolved, simplest yet fundamental problems in physics is the question of the speed of gravitational action. It is usually formulated as follows. Suppose that the Sun disappeared suddenly. This would be sensed on Earth as a loss of gravitational pull of the Sun and as a loss of sunlight. Obviously, sunlight would disappear after 8.3 minutes. The question is: will gravitational pull of the Sun on Earth disappear instantaneously or with a delay of the speed of light?The accepted, mainstream understanding is that loss of Sun’s gravity would also be felt on Earth with a delay of the speed of light. However, based on astronomical observations, some experts have argued that the direction of gravitational pull of the Sun on Earth now is directed towards the position of the Sun now, implying instantaneous transmission. Moreover, they have argued that finite speed of gravity will result in instability of planetary systems. However, another line of reasoning has also shown that this literal view of instantaneous transmission is also wrong. This paradox leads us to a profound conclusion that the speed of gravity has dual nature: light speed and instantaneous.How can this be? The new finding is that causality will be (apparently or actually) violated in gravitational phenomenon as follows. Suppose that the Sun disappeared at time t = 0.The strange thing is that the Sun will anticipate its disappearance and will emitzero gravitational field toward the Earth 8.3 minutes before its actual disappearance! This signal travels at the speed of light and reach the Earth after 8.3 minutes. This means that the signal of zero gravitational field will reach the Earth at time t= 0. The arrival of zero gravitational field at the Earth will coincide exactly in time with the disappearance of the Sun, implying instantaneous transmission. Thus, by apparent violation of causality, nature allows the speed of gravity to be both finite (light speed) and infinite.Actually, the discovery of this idea of causality violation did not emerge from investigation of the gravitational phenomenon discussed above. It emerged from a line of reasoning during investigation of quantum phenomena, such as particle interference patterns in double-slit experiments, quantum entanglement, “which way” and quantum erasure experiments.From a new insight about the internal structure and dynamics of quantum particles such as photons and electrons, a conclusion has been reached that the exact point on the detector screen of a double-slit experiment where a photon will land is completely predetermined by fine tuning the initial conditions of the photon and the electron during emission. This means that where exactly a photon lands on the detecting screen is completely predetermined by its initial conditions, just as where exactly a ball lands on the ground is predetermined by its initial conditions. This means that an interference pattern or any arbitrary pattern could be formed on the detector screen by (almost) infinitely fine-tuning the initial conditions of the photon during emission, regardless of whether one or both slits are open, regardless of the distance between the slits, regardless of the distance of the detecting screen. In principle, a mechanical version of particle interference patterns can be created by repeatedly kicking a ball towards a hole (‘slit’ ) in a wall, with a ‘detector’ wall at some arbitrary distance from the hole(s). This would require almost ‘infinite’ fine tuning of the initial conditions of the ball, that is initial velocity, initial direction and other parameters. The interference pattern occurred just because of infinite fine tuning of the initial conditions of the ball and not because the ball ‘interfered’ with itself. We only made a successful simulation, and created the pattern as if the ball interfered with itself. A supernatural football player can create an ‘interference’ pattern on the net by accurately deflecting the ball from either pole. The interference pattern in the photon and electron double-slit experiment is fundamentally the same. The conclusion is that aiming a photon to a particular atom on the screen requires (almost) infinite fine-tuning during emission. This raises the burning question: WHO fine-tunes the photons during emission so that they form an interference pattern or a Gaussian pattern? The emitting atom?The light source conspiring with the detecting screen? Atoms have infinitely small intelligence as to do the infinitely complex task of fine-tuning a photon. The conclusion is that a super natural being is fine-tuning and, literally, aiming each and every photon emitted not only from the light source of a double slit experiment, but also all photons emitted from all light sources in the universe. The overwhelming evidence of divine intervention is that photons and electrons cannot by themselves behave both as waves and as particles simultaneously. LITERALLY, God has been behind all confusing light speed experiments and observations made over centuries. It has been discovered that the correct model of the speed of light is a novel, seamless fusion of ether theory and emission theory ( Apparent Source Theory ). Photons cannot by themselves exhibit this dual nature. Literally, all dualities observed so far in light, electromagnetism and gravity are possible ONLY by DIRECT divine intervention.
