The argument that gravity must travel faster than light goes like this. If its speed limit is that of light, there must be an appreciable delay in its action. By the time the Sun’s “pull” reaches us, the Earth will have “moved on” for another 8.3 minutes (the time of light travel). But by then the Sun’s pull on the Earth will not be in the same straight line as the Earth’s pull on the Sun. The effect of these misaligned forces “would be to double the Earth’s distance from the Sun in 1200 years.” Obviously, this is not happening. The stability of planetary orbits tells us that gravity must propagate much faster than light. Accepting this reasoning, Isaac Newton assumed that the force of gravity must be instantaneous.
Astronomical data support this conclusion. We know, for example, that the Earth accelerates toward a point 20 arc-seconds in front of the visible Sun—that is, toward the true, instantaneous direction of the Sun. Its light comes to us from one direction, its “pull” from a slightly different direction. This implies different propagation speeds for light and gravity.
Wouldn't it be ironic if we reverted to the horse and buggy technology of the 19th century only to learn that the climate on the planet (as well as Mars, where warming is also occurring) is overwhelmingly influenced by the sun's cyclical activity? In other words: "I sacrificed my favorite goat (the technological ability to adapt to natural forces) to the warmista gods only to learn that it was all a scam by the witch doctors (politicians) to increase their power". Two U.S. Senators (Snowe (R) Maine Rockefeller (D) W. Virginia) have issued veiled threats to at least one of those who support the skeptics financially.
