The physics and mathematics for both equations is *completely* different but relativists have mixed both without sound basis. I remember a funny discusion in this newsgroup with 'expertise' Steve Carlip about those issues. For instance, Carlip confounded the selection of physical boundaries for the PHI^* potential with the selection of energy scale for the PHI_0 potential. And then Carlip started to claim that the problem of unphysical boundaries of the GR potential was also present on the Newtonian term. But that was plain wrong. From a mathematical point of view Carlip confounds solutions for the Poisson equation (time implicit dependence) with solutions for the stationary D'alembert equation (time explicit dependence). Carlip makes this mistake for both electromagnetism and gravity. I tried to correct him several times but...

Professor Carlip's suggestion of including the aberration into the
effect of gravity can be refute by the mathematics of vector additions and the Galilean transform. After all, GR must degenerate into the Newtonian law of gravity at low gravitation and low speed such as the solar system and the binary stars. Consider two objects orbiting each other. Let the following be the position vectors of interest. ** [s] = Position vector form the common center to the unprimed NOW ** [s'] = Position vector from the common center to the primed NOW ** [s'_-T] = Position vector of the primed THEN (retarded position) ** T = Retarded time [s] and [s'] should then form a straight line through their common center at the moment NOW. If the speed of gravity is finite (say V), the retarded position of the primed becomes the gravitating distance for the unprimed to feel the effect in gravitation of the primed. The position vector of the primed as observed by the unprimed becomes the following. [s''] = [s'_-T] - [s] If the speed of the primed has not changed much from THEN to NOW, then we have the following simplification. [s'_-T] = [s'] - T d[s'_-T]/dt Where ** T = s'' / V ** V = Speed of gravity The effective gravitating distance [s''] becomes the following. [s''] = [s'] - [s] - T d[s'_-T]/dt With the effective gravitating distance of [s''] and V = c, the solar system would fly apart in a few short centuries. Yet, it does not. That enabled Laplace to calculate V to be several million times c. All of a sudden, Professor Carlip came along and suggested that gravitational effect is subject to aberration. According to him, the effect of aberration will nullify the effect of the retarded position up to the first few orders. So, applying the effect of aberration to the effective gravitating distance [s''], we have the following under the Galilean transform. [s'''] = [s''] + [v] T Where ** [v] = Velocity of the primed THEN as observed by the unprimed So, this velocity is [v] = d[s'_-T]/dt - d[s]/dt The effective gravitating distance with aberration correction [s'''] become the following. [s'''] = [s'_-T] - [s] + T (d[s'_-T]/dt - d[s]/dt) Or [s'''] = [s'] - [s] - T d[s]/dt Comparing the effective gravitating distances [s''] and [s'''], the effect of [s'''] is more dramatic if the mass of the primed the mass of the unprimed. This is obvious not according to observation. Thus, Professor Carlip's suggestion of aberration in gravity is only a myth. This is a fine example where mysticism plays a major role in GR. shrug On Apr 3, 10:59 am, Koobee Wublee wrote: On Apr 2, 10:13 pm, Tom Roberts wrote: For those unwilling to wade through the umpteenth time this has been discussed, here is the bottom line: Scientists TEST THEORIES.

Physicists are able to play shaman by turning an ordinary matrix into a tensor just saying 'abracadabra'. Binary pulsars are an obvious example, as I demonstrated (without any dissent) in Reference B below. To claim you demonstrated it is wrong, and to claim "without dissent" is a bald-faced lie. You even published a comment on the major dissenting paper. With the mysticism in aberration of gravitational effect fails miserably, the anomaly in the orbit of a binary system can be interpreted that the propagating speed of gravitational effect is much higher than committee-accepted. This is scientific discussion not a sermon. shrug No, it is not. But to understand this one must actually use GR, which you quite clearly do not understand (more on this below). But even the simplest orbit computation program can show the same thing. If you use light-time-retarded positions of bodies to compute orbits, the computed orbits are open spirals, in contradiction to observations. How silly can you get???? The subject here is GR and its relation to experiments. To address that you must use GR, and not whatever it is you have cobbled together with "light-time-retarded positions". I repeat: In the model of GR, gravity does not propagate at all, but changes in gravity propagate with speed c. You have said NOTHING that addresses this, much less refutes it as you claim. So, through your own interpretation of GR, you do not allow gravity to propagate. What you are saying is the-speed-of-gravity-is-infinite in disguise. Nor do the field equations describe ordinary orbital motion. You need to LEARN what GR actually is. Yes indeed, the field equation of GR does describe "ordinary orbital motions". You are still making the same mistake again. You are confusing the Einstein field equations with geodesic equations. These two sets of equations are independent from each other. For instance, any GR textbook will derive the equations of orbits in Schwarzschild spacetime. Yes, you need to read these GR textbooks more carefully, and understanding the mathematics also helps. The solutions to the field equations are the elements to the metric. That is all. It does not tell you how an object is going to behave in motion. HINT: the field equation is G=T; the covariant divergence of G is identically 0, and the equation obtained from setting the covariant divergence of T to zero does indeed yield the equations of motion. You don't know what you are talking about. Setting G to zero, allowing you to solve for spacetime in free space. It is equivalent to the Laplace equation or the Poisson equation setting to zero. These equations do not tell you the geodesic motion. When T describes objects orbiting, those equations describe the orbits. Yes, nobody knows how to solve those equations analytically, but various approximations are applicable, and numerical solutions have been performed; both are in excellent agreement with observations. Here is mysticism talking, on the contrary, yours truly have gone through several metric derived from the field equations personally. You can solve them. one must take a gradient of the potential (or its equivalent) to get what you like to call an "approximation" theory. The approximation is MUCH more involved than that. I repeat: you REALLY need to learn what GR actually is, and how it is applied -- your guesses are just plain wrong. To derive the geodesic equations, you must define your mathematical model of motion. All motions obey the principle of stationary action. In doing so, if you decide the only path through spacetime from one fixed point to another is the one path that would allow you to accumulate the least amount of spacetime, you have a set of geodesic equations based on this mathematical model of motion. Also, I have been telling you this model of motion is utterly absurd because it would not allow photons to propagate. This is because for a photon every single path always accumulate an amount in spacetime of exactly zero. This was a mistake carried over from the Goettingen group of mathematicians including Hilbert, Klein, Schwarzschild, and Minkowski. They did not think properly applying the mathematics to real life. They just extended what Christoffel did. The "speed of gravity" is not a model-dependent concept except at the level of parts per 100 million, any more than "perihelion motion" is model-dependent. NONSENSE. None of the experiments you cite actually measure any speed (see above). And to relate their measurements to speed requires EXPLICIT model dependence. GR does not fit that model, and does explain those measurements without any "propagation of gravity", at any "speed". You have basically decided that the speed of gravity is infinite by your own interpretation of gravity-never-moves-nonsense. In doing so, you are not either reading and comprehending the opposing point of view or just being unreasonable. As I have said befo scientists TEST THEORIES. Let engineers measure things. None of the experiments you cite refute GR -- THAT is what is important, not the fact that you can use other models to interpret them as measuring "speed of gravity". So, engineers are mere technicians for your disposal. You are the smart one able to understand the physics. Well, the GPS episode shows that you are utterly wrong here. Relativists like to redefine the concept to refer to the speed of changes in the gravitational potential field, which everyone agrees is c. But that refers to gravitational waves, and avoids the issue of the propagation speed of gravitational force for determining the ordinary orbital motion of two masses around a common center of mass. One must either give up the causal link to a source mass, or agree that the force propagates from the source mass to the target body faster than c. Not true -- there is a third possibility, the one the usual approximation to GR uses: propagation is at c, but the force at distant locations depends on position, velocity, and acceleration of the source mass. They combine to make the gravitational force not be central, and to point approximately to where the source mass is located at the time of observation (and for many cases the approximation is excellent). Here is another myth. The field equations do not tell you about gravitational waves propagate. Let alone the myth about the field equations tell you how fast gravity should propagate. Regardless of how you may personally feel about it, GR is the mainstream theory of gravitation today. It is ridiculous that you attempt to write about gravity without understanding the first thing about GR. And it's even sillier that you attempt to "describe" what GR says or how it applies. Yes, GR is a main stream conjecture in understanding how gravity behaves. The notion is not much better than Christianity is the main stream religion in the western civilization. shrug Bottom line: scientists TEST THEORIES. Let engineers measure things. None of the experiments you cite refute GR -- THAT is what is important, not the fact that you can use other models to interpret them as measuring "speed of gravity". Here we go again about you being the king of wisdom. Yet, you do not even understand the difference between the field and the geodesic equations. shrug |

I said was: {BLOCKQUOTE This confusion is also characteristic for gravitation.

My work also proves that the geometric formulation of GR holds only limited applicabiltiy. I have been also formally invited by one of organizers to explain my GR work in a recent cosmology conference. A similar confusion on electromagnetism have been recently corrected in top journals like Physical Review, see cited references. In all published papers and my recent work the conclusion is that interactions are not retarded by c.

Hi Juan, understood. Doesn't seem. In the notation of Chubykalo and Smirnov-Rueda [1], they may be rewritten like a = - GRAD PHI^* and a = - GRAD PHI_0 And then one can easily see they are not the same equation. I can do that, 1 = 5-4 1 = 6-5 are NOT the same equations. But in you above trivial equations the right hand sides are equivalent 5-4 = 6-5 However the righ hand sides of the recently derived equations of motion verify PHI^* =/= PHI_0 The first is a local time explicit potential (with usual retardation t_0). The second is a nonlocal time implicit potential (without retardation). The physics and the math are different for both equations. That is the reason they (and me) use a different notation for both potentials. Relativist literature confound both. Mistakes have been recently corrected in literature. In one of papers cited (the Physical Review paper) the authors mathematically proved that four-vectors A^*b and A_0^b are irreducible forms. They are components of a more general representation contains a complete solution for the combined Poisson and D´alembert mathematical problems with *continuous* transition between steady and nonsteady solutions. You also failed to understand that the new *instantaneous* potentials PHI_0 and A_0 cannot be derived from relativistic electrodynamics. Relativistic electrodynamics only accounts for the retarded component of the interactions. That is reason that everyone relativist will say you that the speed of EM is c. But that is not longer true. Science advances. I remark again the new theory contains relativistic electrodynamics and special relativity as a particular case. As said before their work have been generalized to gravitation by me. The new instantaneous gravitational tensor h_0^ab (in Chubykalo and Smirnov-Rueda notation) cannot be obtained from General Relativity. General Relativity only can explain the h^*ab tensor. It is this term which is retarded by c. That is reason that general relativists will say you that the speed of gravity is c. But that is not longer true in the light of recent advances. Moreover, we know that the h^*ab = h^ab term has geometric interpretation g^ab = n^ab + h^ab And this gives the geometric formulation of General Relativity. Interestingly the new term h_0^ab has no geometric interpretation as i have proven in my last work. Geometry (and the own concept of spacetime) may be derived as a special case. We start from the first-order extension of a Liouville space extension of classical dynamics. When one applies a pure state approximation in the (+) semigroup one derives spacetime, geometry, Maxwell electrodynamics... after some pages of nontrivial computations. Since the new theory reduces to the former theories on the local limit, the new theory also explains all the experimental results were well- explained by former theories. One big advantage of the new theory is that eliminates traditional difficulties and paradoxes of relativistic formulations. E.g. the traditional inconsistencies of Maxwell electrodynamics were eliminated in the Physical Review paper cited, take a look. Another big advantage of the new theory is that can explain phenomena cannot be explained by usual relativistic theories (SR, relativistic electrodynamics, GR...). For instance my work on gravitation eliminates several known difficulties with General Relativity regarding the role of cosmological boundaries. Probably that was the reason which people who read the draft invited me to explain my recent research work on the international conference on experimental cosmology i cited in another part. The techniques i have developed are completely general and can be also applied to other formulations as 8N StuckÍlberg mechanics. See Ken again you failed to understand everything: potentials, equations of motion, retardation, speed of interactions, radars, geometry... I have learn the lesson; I have decided i am not good explaining stuff on 'plain' terms. Also i will not waste time replying trivial questions as that of RADARS. Here in thereafter i will restrict to academic/research postings. The below guidelines will be updated, eliminating the point "use a plain language". -- http://canonicalscience.org/en/misce...guidelines.txt |
