Untutored imbecile. The advance is a textbook exercise. That may be so, but what's your point? Any text book exercise can be based on dubious logic. Anyway I really don't need to know how GR explains the advance because it's fairly inconsequential to the gravity anisotropy. Regardless of how Einstein chose to explain the advance, this is obviously how it actually works. http://members.optusnet.com.au/maxkeon/sun-merc.html The following two paragraphs are an update on the web page. The original was very poorly worded. The wording didn't match the results. ----------- The 80 second time shortfall difference between the aphelion and perihelion radii was determined assuming that time measurements can be determined as they are in the realm of matter, which is wrong. Converting the time measurements to the realm of matter by taking the square root of (aphelion radius divided by the speed of light) and subtracting from it the square root of (perihelion radius divided by the speed of light), results in a time shortfall equivalent in the realm of matter of 2.89 seconds. With the average radial velocity set at 5000 m/sec; 5000 * 2.89 * 2 = 28900 meters is the advance per orbit cycle, which is 42.63 arcseconds per century. Mercury's average radial velocity is (aphelion radius-perihelion radius (2.4e+10)) divided by the half cycle time of 3801600 sec = 6313 m/sec. But that isn't correct for the above purpose because the maximum velocity occurs when Mercury is aligned with the Sun along a line which is perpendicular to the line through the aphelion and perihelion. Most of its time is spent in the lower velocity zone, where the time delay is greatest. ----------- Now that I have your attention, perhaps you would like to comment on what you think these two paragraphs imply. This was a reply to Robert Kolker, from Ian Parker: --------- The GR correction is on top of all other perturbations. I don't know anything about elasticity, the simple fact of the matter is that Mercury is determined by the Scwartzchild metric, that is to say it is attracted not to the center of the Sun but a point some distance away - the Schwarzchild radius. ----------- That is similar to this excerpt from Britannica: ----- The general theory of relativity, however, accounts exactly for this discrepancy. In 1967 Dickeu and more recently Henry Allen Hill, also of the United States suggested that a small part of Mercury's perihelion advance may be caused by the slight flattening of the Sun at its poles, thus opening the way for possible modification of general relativity. ---------- ??? Only idiots who can't even handle basic calculus seem to think they can sniff at GR and not be called stupid for their troubles. And perhaps you would now like to list the fundamental elements involved in the GR calculation, and demonstrate the means by which they are applied to achieve the final result. I've already shown you how mine works. ----- Max Keon |

The Schwarzschild radius is a locus of points that form a SPHERE of radius 2GM/c^2. The center of attraction is the CENTER OF THE SPHERE. How stupid can you possibly be? Reply and we'll find out.

The untutored idiot realizes his status. The technical term is oblateness, which gives the sun a quadrupole moment. Classical pertrubation theory is quite explicit regarding the effects of quadrupole [and higher] on perihelia advances. Again, another textbook exercise in another textbook that I have studied which you have never opened. Observation violently excludes the required solar quadrupole moment. This was known decades before Dickeu and Hill uttered those stupidities. Furthermore, the "possible modification" assumes unwarranted intelligence on the person who wrote it [you]. Schwarzschild assumes spherical symmetry. Only idiots who can't even handle basic calculus seem to think they can sniff at GR and not be called stupid for their troubles. And perhaps you would now like to list the fundamental elements involved in the GR calculation, and demonstrate the means by which they are applied to achieve the final result. I've already shown you how mine works. Yours is incoherent numerology that has no theoretical basis which does not work for any other planet, asteroid, or orbiting floatsam. That it even works for Mercury is an assumption I generously grant because I don't feel like pulling out the calculator and checking your numbers. The derivation of the perihelion precession of Mercury is available in any textbook on the subject, derivable by any student well versed in classical mechanics and perturbation theory, or in the original goddamn article in 1916. What's your excuse, untutored idiot? Demonstrate an understanding of something beyond middle school algebra, or go away. ----- Max Keon- Hide quoted text - - Show quoted text -- Hide quoted text - - Show quoted text - Its not an advance.

I'm not going to get involved in your silly little game of trading insults. I'll just stick to the facts. GR has predicted an anomalous perihelion advance that was not anomalous in the first place, IN YOUR UNIVERSE. A time delay in the gravity link between the Sun and Mercury obviously exists, and that delay just as obviously varies as Mercury moves between the aphelion and perihelion of its orbit. When Mercury is at its perihelion radius, the time delay is r/c. 4.6e10 / 3e8 = 153 seconds. At the aphelion the delay is 233 seconds. 80 seconds in the gravity link has been lost during the journey. That means, for 80 seconds, Mercury is free of the pull to the Sun (and vice versa of course). Its outward motion is not restrained for that time. With the pull of gravity at the mean radius, .039m/sec^2, and an average radial velocity of 6313m/sec; ..039 * 80 * 6313 = 19697 meters. Mercury will overshoot what would have normally been its aphelion by almost that amount. On the downward leg the pull to the Sun has gained an extra 80 seconds and Mercury will bypass its normal perihelion radius by a similar amount. The orbit eccentricity is no longer naturally flowing in the Sun's inertial frame. This secondary system is exactly the same as that generated by the anisotropy, but much amplified. This is what will happen to the eccentricity if nothing changes. http://members.optusnet.com.au/maxkeon/mercad1.jpg As you can no doubt see, maintaining a circular orbit would be almost impossible because the slightest eccentricity would generate a small time delay which would add to the orbit eccentricity, and that condition would develop exponentially until the orbiting components completely fly apart. But the system has been evolving for millions of years and it will be nothing like what is shown. It's all explained on the newly updated web page. http://members.optusnet.com.au/maxkeon/sun-merc.html --- And perhaps you would now like to list the fundamental elements involved in the GR calculation, and demonstrate the means by which they are applied to achieve the final result. I've already shown you how mine works. Yours is incoherent numerology that has no theoretical basis which does not work for any other planet, asteroid, or orbiting floatsam. It gives an "anomalous" orbit eccentricity advance rate at the mean radius for Pluto of 50000 meters per orbit. I'll post the program I'm using when it's more user friendly. ----- Max Keon |

The anomalous perihelion advance is called such because it predates GR and was the remainder when all known Newtonian effects were taken into consideration. [snip remaining idiotic numerology] The truth will always be our master, Eric. It may not set us free but at least we'll be on the right tram. Here are some excerpts from the last two updates to the web page http://members.optusnet.com.au/maxkeon/sun-merc.html Mercury's average radial velocity is, (aphelion radius - perihelion radius) 2.4e+10 divided by the half cycle time of 3801600 sec = 6313 m/sec. But that isn't correct for the above purpose because 100% of the radial velocity is not effective in advancing the eccentricity. The 100% only occurs when Mercury is aligned with the Sun along a line which is perpendicular to the line through the aphelion and perihelion. I don't know what the true balance is, but 5000 m/sec was chosen because it gave the correct result, and it wasn't going to be too far out. 5000 m/sec is 79% of the average. http://members.optusnet.com.au/maxkeon/rvel.jpg 15-11-2008 I'm now using a coordinate system to generate the results, and that's resulting in a greater degree of advance than before. For the 100% effective radial velocity, the advance is 41690 meters per orbit, requiring only 70% of the total radial velocity to be active to achieve the correct result. (6313 * .7) * 2.89 * 2 = 25542 meters is the simple advance, which is too little, but that's not what eventuates when the orbit cycle is indexed around in discrete steps. The final result, 46190, multiplied by .7 is 29183, which is near enough for the purpose. The .7 figure may seem a little low perhaps, but there will be a reason for that, as there always is. The result is almost identical using more conventional logic. For the missing 80 seconds in the Sun-Mercury gravity link enroute to the aphelion, where the Sun and Mercury have been further separated in time, with the average Newtonian gravity rate for the orbit cycle of .04m/sec^2 and an average radial velocity of 6313m/sec, the advance per half orbit is ..04 * 80 * 6313 = 20202 meters, or 40404 meters for the complete orbit. 40404 * .7 = 28283 meters. The results are similar because each system tells much the same story. 18-11-2008 The program now addresses the radial velocity per angle problem and the results are better than expected. The orbit eccentricity advance at the mean orbit radius in the Sun's frame is 31637 meters per orbit, which is 46.67 arc-seconds per century. That's around 4 arc-seconds more than is predicted by conventional logic, which doesn't address the time delay problem at all. What other effects might the time delay have? -------------- This is the attached program. Try not to word-wrap any lines.
