Andersen" wrote: This formula looks better since with the melting of the polar ice caps the precession period ought to get longer. shrug This is a phase. This is only valid after 2000 and after for a few centuries. shrug Not at all. The J000 is but a - not entirely arbitrary - chosen reference point. As you possibly know, the equatorial coordinate system is used by astronomers to give the position of stars and other objects. This is a spherical coordinate system with the coordinates declination (Dec) and Right ascension (RA). The Dec is the angle from the equatorial plane, and the RA is the 'horizontal' angle from the vernal equinox. Since the vernal equinox is moving, and it would be very impractical to continuously rework the star charts, it must be specified which year (epoch) a set of coordinates is valid for. Standard years are chosen, usually every 50 years or so. The currently used epoch is J2000. This is the reason why J2000 is used in the Equation for pA above. So when you find the coordinates of the star in a EPOCH2000 star chart, the angle pA for the current year is what you have to add to the charted RA to find its real position. The equation is valid several centuries in both direction. But the _chance_ of the angle of precession per century is: p = dp_A/dt = 5028".796195 + 2".2108696 t + 0".0001302 t^2 + .. This is an angular frequency. So, according to Paul, 230k years ago, the precession was null. shrug No, because then the higher order terms would come into play. The result would be ridiculous, though. It would be equally ridiculous for 230k years in the future. Let’s see if that equation agree with you. Say t is indeed -1.5 (150 years ago when Le Verrier made his final measurement on Mercury’s orbit) and -2.5 (250 years ago when Le Verrier’s data started). pA at -1 .5 = 5028”8 (-1.5) + 1.1 (-1.5)^2 = -7544”5 pA at -2 .5 = 5028”8 (-2.5) + 1.1 (-2.5)^2 = -12578”9 Correct numbers: pA(J1850) = -7540.7074534702 arcsecs pA(J1750) = -12565.0836925488 arcsecs The rate ought to be (12578”9 – 7544”5 = 5034”4) which is not probable. Paul is a joker. Paul is a mathemagician. shrug Correct numbers: pA(J1850)-pA(J1750) = 5024.3762390786 arcsecs per century p(J1800) = 5024.3761718400 arcsecs per century (the two are not exactly equal because the curve isn't linear) What's your problem with this? However, Clemence estimate is based on observations from 1765 to 1940, so 1850 is a more reasonable middle year. http://www.gethome.no/paulba/pdf/Clemence.pdf p(1850) = 5025.4807492700 arcsecs per century And if you wonder if your way of calculating agrees with this: pA(J1900) = -5027.6908636587 arcsecs pA(J1800) = -10053.1716684064 arcsecs pA(1900)- pA(1800) = 5025.4808047477 arcsecs per century Clemence did not understand that the effect on Mercury’s orbit due to other planets would depend on where the planets were during the course of that 100 years. Clemence did not have any justification to place Le Verrier’s numbers within such accuracy. It is almost impossible to calculate, but it is easier (but still no trivial task) to simulate. shrug Conclusion: GR's prediction for the 'anomaly': 42.98 +/- 0.04 is well inside the error bar. Not quite. All these effects on Mercury’s orbit including GR one if indeed exists are not linearly additive. Any parameter will affect the final outcome depending on what other parameters are. You will realize this if you actually study the differential equations involved. Paul Gerber simplified the system as linear, and Koobee Wublee thinks he was wrong. The only way to address this is to do: ** The actual measurement which has more than 100 years of data ** Simulation on the entire system The difference should be the value reflected by the precession of the equinox. shrug Conclusion: the whole of physics came to a standstill 100 years ago because Mercury's orbit was presumed to continuously precess for no apparent reason and a couple of crazed scifi fanatics made wild guesses down to twenty eight decimal places as to how much it did so each century.

His result was a recycle of Le Verrier’s observation about 8 decades prior. Le Verrier was not set out to measure the accuracy down to the last second, but his motivation was to find a sum of anomaly for him to justify whether if there is another planet further inside the orbit of Mercury. He did not find it. Thus, most of astronomers, and perhaps Le Verrier himself, at that time just attributed the lack of the extra planet to Le Verrier’s own observation accuracy. shrug Clemence realized without pinning down Le Verrier’s observation with better accuracy, the confirmation of GR cannot be definitively claimed. The question to ask is what Clemence’s justification is to claim such extreme accuracy on Le Verrier’s observation 8 decades prior. shrug According to this paper: http://syrte.obspm.fr/iau2006/aa03_412_P03.pdf The _accumulated_ precession, that is the angle of the equinoxes with the angle at J2000 as the reference is: pA = 5028".796195 t + 1".1054348 t^2 + 0".00007964 t^3 + .. (up to t^5) Where t is in Julian centuries since J2000. This is only valid after 2000 and after for a few centuries. shrug Not at all. The J[2]000 is but a - not entirely arbitrary - chosen reference point. [... accuracy good for] 50 years or so. The equation is valid several centuries in both direction. According to the paper, it says clearly that: “The parameter t, used in the above expressions as well as in those below, is the elapsed time in Julian centuries sinceJ2000...” There is no indication that the study would cover the past. So, where did you get the information that the equation is valid for several centuries in both directions, and how many centuries? shrug The motivation for the paper is that the authors felt the established precession value then was not adequate to carry forward. The polar ice caps experienced their greatest retreat in the past two decades. Thus, there is no way that the precession would be linear in several centuries. Besides, Le Verrier called out for 5025” per century then with somewhat relatively primitive instrumentations. Koobee Wublee thinks Paul just happens to find an arithmetic sweet spot and tries to take the advantage of arguing for his beloved GR hypothesis. Of course, Paul’s argument has no basis. Even the authors of the paper specifically specified that the information is good from 2000 and on. shrug What supports Koobee Wublee’s interpretation of the author’s intention? Well, the goal of the paper written in 2003 is to replace the accepted model of 2000 where the formula says: ** PA = 5028”797 t – 1”111 t^2 – 0.000 t^3 If Paul bothers to work out the retroactive precession value, it is embarrassingly out of the ball park. Thus, it can only mean that the value is to be carried forward and not backwards. shrug Clemence has also failed to justify why Le Verrier’s numbers are such accurate, and Paul so far has failed to argument for Clemence. So, is Paul disputing that any orbital anomaly is position dependent? shrug Thus, the justification to why Le Verrier’s measurement of 5,600” is actually 5,599”74 +/- 0”5 remains not justified. According to Clemence’s paper, he said: “The contributions of the planets are directly proportional to their several masses, which are NOT ALL KNOWN WITH THE DESIRED ACCURACY. The quantities denoted by m^-1 are the reciprocals of the adopted masses, the sun’s mass being taken as unity, and the attached probable errors give rise to the probable errors associated with the theoretical contributions to the motions. In the case of Mercury each planetary contribution (except that of the Mercury itself) is the sum of three parts: the motion of the perihelion in the plane of the orbit, the contribution arising from the motion of the node, and the contribution from the motion of the ecliptic...” Clemence did not understand that the effect on Mercury’s orbit due to other planets would depend on where the planets were during the course of that 100 years. Clemence did not have any justification to place Le Verrier’s numbers within such accuracy. It is almost impossible to calculate, but it is easier (but still no trivial task) to simulate. shrug Also, all these effects on Mercury’s orbit including GR one if indeed exists are not linearly additive.

As you possibly know, the equatorial coordinate system is used by astronomers to give the position of stars and other objects. This is a spherical coordinate system with the coordinates declination (Dec) and Right ascension (RA). Let me help you out here and correct a mistake that runs through empirical science since the vicious strain of empiricism arose with Newton in the late 17th century. The framework you are trying to describe requires more than a few qualifiers such as the predictive element of Ra/Dec is founded on the 24 hour AM/PM cycle within the 365/366 day format hence the mistake Flamsteed made was assigning significance to stellar circumpolar motion in terms of the Earth planetary dynamics and specifically daily rotation - http://californiamapsociety.org/historic/flamsteed.php "... our clocks kept so good a correspondence with the Heavens that I doubt it not but they would prove the revolutions of the Earth to be isochronical... " Flamsteed to Moore Whereas the great astronomers used the motions of the planets AGAINST the stellar background ,the equatorial coordinate system has the planets move WITH the stellar circumpolar background in a grotesque rotating celestial sphere diorama.The is the first and last time I will capitalize words in any thread in all these years so important is the distinction .When Kepler registered the motion of Mars from a moving Earth,he is using the background constellations as a marker for orbital motions and orbital motions alone - http://en.wikipedia.org/wiki/File:Ke...retrograde.jpg Even to this day empiricists still think it is a geocentric description and the basis for Newton's heliocentric/geocentric equivalency by virtue that he uses the rotating celestial sphere of Ra/ Dec to transfer what he imagines are geocentric observations to heliocentric descriptions without any loss of information - "That the fixed stars being at rest, the periodic times of the five primary planets, and (whether of the sun about the earth, or) of the earth about the sun, are in the sesquiplicate proportion of their mean distances from the sun.This proportion, first observed by Kepler, is now received by all astronomers; for the periodic times are the same, and the dimensions of the orbits are the same, whether the sun revolves about the earth, or the earth about the sun." Newton The guys in the early 20th century couldn't make heads nor tails of Sir Isaac's absolute/relative space and motion backed up by the equatorial coordinate system with its exceptionally flawed conclusion of Flamsteed in jumping the gun with the Ra/Dec framework in that is is great for predicting astronomical events such as eclipses,transits and the time of the Solstices as a time and date within the 24 hour AM/ PM system and the 365/366 day calendar system but useless for proving the Earth's motions which in turn affect observations in the celestial arena. I guess it is too intellectually tough for mathematicians just like Leibniz said it would be - "These are the imaginings of incomplete- notions-philosophers who make space an absolute reality. Such notions are apt to be fudged up by devotees of pure mathematics, whose whole subject- matter is the playthings of imagination, but they are destroyed by higher reasoning" Leibniz I see a lot of people scrambling around with terms they barely comprehend and that is dismaying insofar as empiricists were responsible for this problem they also must be part of the solution. |
