Then it's pretty well established that one wouldn't detect the effect from Ulysses. If it is that far away it isn't a fit instrument upon which to base a measurement in the first place. Lack of evidence is not evidence of lack. Illogical argument. The planets lie both both within and beyond 5 AU. A putative gravitational anisotropy which affects the planets will also affect Ulysses. No such effect is seen in Ulysses tracking data. You're being illogical. Ulysses only momentarily (compared to the time it spends outside of the ecliptic) cuts the ecliptic, therefore it is not likely that you'd be able to detect the effect. This claim is unsubstantiated. Radiometric Doppler tracking is extremely sensitive to anomalous accelerations (changes in velocity ~10^{-9} of the Sun's gravity at 1AU over 1 day), and no such latitude-dependent anomalies are detected. You have not provided estimates of the magnitude of the acceleration, or the size of the region around the ecliptic where the putative accleration would apply, so it is indeed *not* "well established that one wouldn't detect the effect from Ulysses." You have provided no basis to say whether it could or could not be. You've provided no basis to say that it would be detected either. I think that the claim is substantiated by data simply because the gravity field is aniostropic and the greatest acceleration would lie along the ecliptic. Most of the bodies of the solar system lie within a few degrees of the ecliptic and that itself is data that suggests that such region is the lowest energy state plane for the solar system. But it isn't really the plane of the ecliptic that is of interest but rather what I'm interested in should be defined as the gravitational plane produced by the anisotropic nature of a monolithic gravtitational source in the first place. There are other bodies whose orbits lie outside of the ecliptic plane, such as Asteroid 9969 Braille (29 deg; 1.33 AU perihelion); 19P/Borrelly (30 deg; 1.36 AU); 5381 Sekhmet (49 deg; 1 AU semi-major axis); 10563 Izhdubar (63 deg; 1.0 AU); and of course Pallas. Mercury's orbit lies 7 degrees of the ecliptic, and Venus's is at 3.4 deg. This is further substantiation that solar system bodies are not constrained to the ecliptic. There you go again erecting straw men. I never once said that the solar system bodies are constrained to the ecliptic. I said that most planets are within a few degrees of the ecliptic. When a planet exlodes as did the planet which now lies as the scattered ruins which compose the asteroid belt some of the components will certainly depart from the elciptic. Not enough time has passed to bring them back. The more closely the angle of their orbit to a normal to the ecliptic the longer it will take. Claims that high latitude asteroids could have come from an exploded planet are unsubstantiated; they are not in the asteroid "belt." There you go with that catchphrase 'unsubstantiated'. 'Substantiation' is related to 'evidence' which is nothing more or less than the subjective interpretation of the data and 'proof' (which you might link to the concept of 'substantiation') is only an arbitrary amount of 'evidence'. Whether or not a thing is 'substantiated' turns out to be a matter of opinion when used in the way that you have been found using it. So, you become like a little child saying with an argumentive companion 'is', 'is not', 'is too', 'is not' and so on and so forth. Perhaps you could restrain yourself from such a puerile argument style and include in your declarations that you don't accept a thing as substantiated instead of you present technique of attempting to tie 'substantiation' to something other than mere opinion which it really rests upon in the way that you use it. Mercury and Venus, which are not asteroids, have the second and third highest planetary inclinations from the ecliptic. In any case, the definition of the ecliptic is a purely imaginary construction, namely the plane of the earth's orbit. Even the sun's rotation axis is inclined with respect to the plane of the ecliptic. The fact that the planets lie primarily in a plane is not an argument for or against a non-spherical mass distribution within the sun. Sure it is. Below you make it an argument for a common origin. Bodies all obtain to the lowest energy state possible; this is an axiom upon which thermodynamics is based. The idea that all of the planetary bodies are occupying a low energy state orbit argues strongly for gravitational anisotropy. Irrelevant, since all planar orbits in a central body system with the same major/minor axes have the same energy, regardless of orientation. Bodies "obtaining" to a different orbital inclination would need to violate the conservation of angular momentum. An example of an irrelevant factoid being used incorrectly. Conservation of angular momentum is not irrelevant. Angular momentum plays a large role in orbital mechanics. And you're busy using it as an irrelant factoid. As I have pointed out before, a significant non-spherical distribution of mass within the sun would indeed affect the orbits of the planets, because there is an additional 1/r^3 term. Radar ranging to Mars alone constrains any non-spherical component to be negligible compared to the total mass of the sun. The point is that it is not negligible unless you are stark raving blind to the idea that the components of the universe do obtain to the lowest energy state possible. This is so obvious I can only wonder what things you did to yourself which so utterly blocks your intuition. This is an unsubstantiated claim. Using Newtonian mechanics I showed that observations of earth and Mars constrain the distribution of mass within the sun, and any anisotropies must be small. However, it is important to note that the Sun's equatorial bulge should slightly affect the orbits of the asteroids and Mercury, which is consistent with both current theories of gravity and observations. CM A beautiful null content catchphrase 'is consistent with' is used in any number of nonsensical papers. Comets emerging from the outer solar system is consistent with the theory that a huge invisible ogre tosses them at the sun for pitching practice, too. "Consistent" and "inconsistent" are mutually exclusive adjectives. Those experiments which are consistent with a theory are distinguished from those which are not. Therefore, "is consistent with" is meaningful. Interesting that your "straw man" is fantastically nonsensical, whereas my counterexamples are based in observational fact. No they are not. Your examples are based upon the subjective interpretation of data which you have confused with the data itself supposing egotistically that you have interpreted the data correctly. Sorry I bothered you, Craig. I thought you were sharper than it now appears that you actually are. Congratulations, you also have also not lived up to my expectations. The difference is that my expectations were low. CM There you go, then. You intepreted the data according to your expectations. When you do science that way it is pseudoscience and apparently this is the process that you have become familiar with over the years. I actually had high expectations from you but once again I see that there is no connection between certain intellectual skill levels and old fashion wisdom. Rarely, it seems, that they may be found residing in a single individual.

You've provided no basis to say that it would be detected either. *You* are the one who has claimed, either directly or indirectly, that relativity tests using solar system bodies are incorrectly interpretted since they do not account for the putative gravitational anisotropy. The effects of relativity are clearly detected in the motions of the planets and asteroids, and in spacecraft tracking data, in some cases with a signal to noise ratio of 10000. Spacecraft tracking is able to detect acceleration of ~one billionth of the standard Newtonian acceleration at 1 AU. I guess one of the requirements of being a relativistic numbskull is actually NOT to read what Newton wrote and especially the Scholium section,where you get this 'Newtonian acceleration' from I do not know,nowhere in the Principia will you find F= ma and as much as he has to say about acceleration is ; "I likewise call attractions and impulses, in the same sense, accelerative, and motive; and use the words attraction, impulse or propensity of any sort towards a centre, promiscuously, and indifferently, one for another; considering those forces not physically, but mathematically: wherefore, the reader is not to imagine, that by those words, I anywhere take upon me to define the kind, or the manner of any action, the causes or the physical reason thereof, or that I attribute forces, in a true and physical sense, to certain centres (which are only mathematical points); when at any time I happen to speak of centres as attracting, or as endued with attractive powers." Principia http://members.tripod.com/~gravitee/...tions.htm#time So the question arises: should the putative anisotropy detectable above the noise with today's technology, or not? If not, then it's irrelevant to the discussion of tests of relativity. You simply can't designate yourself as anything associated with stars,you definitely must be a theorist who knows no better about Newton,astronomy structure and motion of the cosmos otherwise why would you impose a definition on "Newtonian acceleration" when he himself tells you the distinctions between acceleration as he treats it mathematically and acceleration due to Kepler's second law. Are you all entirely silly or is it that you must go through the Scholium of the Principia line by line for the sake of a guy who completely bungled absolute/relative distinctions.You have so much to learn and unlearn that in some ways I pity you. If the anisotropy should be detectable, then why is it not? Bear in mind that none of the model components contain latitude dependent terms, so neither could mask a supposed anisotropy. I think that the claim is substantiated by data simply because the gravity field is anisotropic and the greatest acceleration would lie along the ecliptic. And, spacecraft tracking techniques are most sensitive to forces along the plane of the ecliptic as the spacecraft passes through the plane, since this direction is along the line of sight. You have not provided estimates of the magnitude of the acceleration, or the size of the region around the ecliptic where the putative accleration would apply, so it is indeed *not* "well established that one wouldn't detect the effect from Ulysses."

The ecliptic does define the plane of the solar system quite well. Even Jupiter, with almost all the mass of the solar system, is in an orbit inclined to the Sun's equator. Obvious but probably misleading counter-example - the moons of the gas giants are almost all in equatorial orbits. -- "Roads in space for rockets to travel....four-dimensional roads, curving with relativity" Mail to jsilverlight AT merseia.fsnet.co.uk is welcome.
