FASTER THAN LIGHT SPEED OF GRAVITY
Einstein’s postulate that nothing can go faster than the speed of
light causes severe problems for current cosmology’s concept of gravity,
for gravity must then travel at the same speed, or a speed less than that of
light. But a gravitational force that is limited to the speed of light will
cause enormous problems for the vast distances it must travel in the
universe. For example, considering that the distance between the sun and
Earth is 143 million kilometers, light from the sun takes 8.5 minutes to
reach Earth. We on Earth don’t notice this travel time because light is
continually being discharged from the sun, but if the sun were to stop
shinning, we wouldn’t notice the absence of light until 8.5 minutes later
(at least according to presently accepted theory about light). Now,
imagine gravity working the same way. Since, as Newton’s laws require,
the sun, in the heliocentric model, is continually tugging at the Earth so
that the Earth does not go flying off into space, then the force of gravity
must be absolutely constant. Current science believes that the force of
gravity travels from the sun to the Earth in 8.5 minutes or more. But this
slow speed of gravity is not said to be a problem because, as is the case
for light from the sun, the gravity sent from the sun to the Earth has been
undisturbed for thousands of years. Its slow speed will not cause any
problems because it already has an established connection between the
sun and the Earth.
Although this may solve one problem, it creates another. By the
same theoretical principle, if the sun were suddenly to stop issuing the
force of gravity, the Earth would immediately depart from its orbit, the
same as when we cut the string from a ball being twirled around in a
circle. Once the string is cut, the ball will depart its orbit. Conversely,
light doesn’t need an anchor in order to propagate. But since gravity is a
radial force in Newtonian physics, it must operate under different laws.
If not, then Newton’s laws cannot be applied to the orbits of planets. The
question remaining is:
what principle of physics would account for the
immediate reaction of the Earth if the gravitational “string” between
them were suddenly cut?(from Galileo Was Wrong)
The effect of aberration on orbits is not seenAs viewed from the Earth’s frame, light from the Sun has aberration. Light requires about 8.3 minutes to arrive from the Sun, during which time the Sun seems to move through an angle of 20 arc seconds. The arriving sunlight shows us where the Sun was 8.3 minutes ago. The true, instantaneous position of the Sun is about 20 arcs seconds east of its visible position, and we will see the Sun in its true present position about 8.3 minutes into the future. In the same way, star positions are displaced from their average position by up to 20 arcs seconds, depending on the relative direction of the Earth’s motion around the Sun. This well-known phenomenon is classical aberration, and was discovered by the astronomer Bradley in 1728.
Orbit computations must use true, instantaneous positions of all masses when computing accelerations due to gravity for the reason given by Eddington. When orbits are complete, the visible position of any mass can be computed by allowing for the delay of light traveling from that mass to Earth. This difference between true and apparent positions of bodies is not merely an optical illusion, but is a physical difference due to transit delay that can alter an observer’s momentum. For example, small bodies such as dust particles in circular orbit around the Sun experience a mostly radial force due to the radiation pressure of sunlight. But because of the finite speed of light, a portion of that radial force acts in a transverse direction, like a drag, slowing the orbital speed of the dust particles and causing them to eventually spiral into the Sun. This phenomenon is known as the Poynting-Robertson effect.
If gravity were a simple force that propagated outward from the Sun at the speed of light, as radiation pressure does, its mostly radial effect would also have a small transverse component because of the motion of the target. Analogous to the Poynting-Robertson effect, the magnitude of that tangential force acting on the Earth would be 0.0001 of the Sun’s radial force, which is the ratio of the Earth’s orbital speed (30 km/sec) to the speed of this hypothetical force of gravity moving at light-speed (300,000 km/sec). It would act continuously, but would tend to speed the Earth up rather than slow it down because gravity is attractive and radiation pressure is repulsive. Nonetheless, the net effect of such a force would be to double the Earth’s distance from the Sun in 1200 years. There can be no doubt from astronomical observations that no such force is acting. The computation using the instantaneous positions of Sun and Earth is the correct one. The computation using retarded positions is in conflict with observations. From the absence of such an effect, Laplace set a lower limit to the speed of propagation of classical gravity of about 10
8c, where c is the speed of light.

"In the geocentric model the ether moves against a fixed-Earth, and the aberration angle of the star is a consequence of the ether’s pressure on the travel of light, which is
opposed to Fresnel’s model that ascribed aberration to the relative motion of the star. "
Relativists cannot make use of Gravitoelectromagnetism Theory, since it is based on the MODIFIED Heaviside-Lorentz equations, and NOT on the original J.C. Maxwell set of equations.
http://sergf.ru/Heavisid.htm (Heaviside attempts to prove that the speed of gravity is the same as that of light, and amazingly presents to the reader the MODIFIED version of the Maxwell equations, and not the original equations which are invariant under Galilean transformations thus permitting faster than light signals to be propagated)
https://www.theflatearthsociety.org/forum/index.php?topic=30499.msg1918701#msg1918701 (velocity vectors are additive, which means that the speed of light can be exceeded)
Nor can the failed Lorentz theory of gravitation based on the MODIFIED set of Maxwell equations be brought into play: the calculations attributed to Laplace stand correct.
Nor can the failed concept of Lorentz transformations be used as any kind of argument against Laplace's calculations:
The colossal mistakes committed by Lorentz and Einstein in deriving the Lorentz transformation/factor:

A sharp analysis of S. Carlip's attempt to prove that the speed of gravity is equal to the speed of light:
"Now let us look at Steve Carlip's paper. His second sentence is this:
The "speed of gravity" must be deduced from astronomical observations, and the answer depends on what model of gravity one uses to describe those observations.This is an unpropitious start. Why? Because it tells us Carlip is misdirecting from the get-go. He is telling us that physicists should and do fit observations to models, rather than models to observations. They do, but they shouldn't. As Karl Popper showed us years ago, science consists of fitting models to observations, not the reverse. Yes, there is some amount of hermeneutics involved, by which previous models may suggest future research; but the current method of jamming all new data into old models by main force and computers is not scientific.
For a start, notice his use of the word “deduced.” That is not only sloppy but false. If your answer depends on your model, it is clear you are inducing your answer, not deducing it. Something that is deduced is a necessary outcome. It couldn't be otherwise because it is logically contained in the data. That is what deduced means. So if various models are giving us vastly different answers, only one can be deduced. The others are induced. More rigorously, they are all induced, but only one is correct.
Carlip's third paragraph starts with this:
In general relativity, on the other hand, gravity propagates at the speed of light.He has just assumed what he is expected to prove here. That is called begging the question. This is typical of the standard model people, who tend to argue in very heavy-handed ways, using all the old tricks. They don't feel they have to convince you of anything, because you are supposed to already be bowing to them. They are certain you are so stupid they can lead with obvious fallacies and fool you anyway. They don't think you will know what begging the question is, or what a red herring is, or what a strawman is, or what a gambler's fallacy is. Most of all, they think you won't be able to spot misdirection, as they slide off the subject and begin discussing things they think you don't understand, like higher math or esoterica.
After that, Carlip begins, yes, misdirecting. Rather than address the question at hand, he tells his reader that the force in GR is not exactly central. What does that have to do with it? He talks about the propagation delay being cancelled, then diverts us into E/M by paragraph 4. But that isn't enough. He then diverts into the second and then the third derivative (of the mass quadrupole moment!), assuming that any mention of a third derivative will scare most readers into silence and acquiescence. Finally, in paragraph 8, he mentions some data, the decay of the orbits of the binary pulsar PSR 1913+16. But once again he just tells us that this is “attributed to the loss of energy due to escaping gravitational radiation.” Since he gives us no data to back that up, he is beggin the question again. We would need to detect escaping gravitational radiation to confirm that, and we haven't detected it. Instead, we have detected photonic and other E/M radiation, which should have decided the question. But Carlip continues to assume what he is expected to prove. He simply calls this decay of orbit a “gravitational damping,” and then says,
The rate of this damping can be computed, and one finds that it depends sensitively on the speed of gravity. The fact that gravitational damping is measured at all is a strong indication that the propagation speed of gravity is not infinite.
But wait, it hasn't been measured at all! It has been “computed.” A computation is not a measurement! Carlip isn't presenting an argument here, he is massaging your brain. He is just calling the real data “gravitational damping,” and then claiming that is proof of something. He might as well say, “The fact that we gave it a name proves it exists in the form we named it.” he deflects us into a short assurance that the decay is due to gravitational damping. And why should we believe that? Because a computer model matched the amount seen to one set of equations in GR. It wasn't even predicted, as he almost admits. Notice his language: the rate can be computed. Yes, but anything can be computed. IF GR had predicted a rate of decay before it was measured, and IF the measurement were made without using the assumptions of GR, THEN he might have something. As it is, he has nothing."
