The title of the article and the claim it was from Cornell.
I dont feel like a martyr.
Let me ask a question. What would you think the article was implying if you saw it for the first time?
Better yet Whats the title of this thread? Why do you think the thread is titled the way it is? are we done now?

Hello Uncinus. Let me ask you an honest simple question. Its not a trick question. It a question of honesty i.e. requires the same fairness given to the possibilities of the subject matter, regardless of a persons conclusions
I hope you give the fairness to my question. For example you say a person can check an ephemeris and it will give the EXACT location for the past 100 years. Personally I can't disagree with that. I dont even want to disagree with that. In fact I think at leaste I hope that those are correct calculations I believe they are but, would I stake my life on the bet that the sun or moon will always be where the calculations say it will be 100 years from now? No I wouldnt , would you? Lets not argue about the few inches or several feet that is updated annually for the the next years point of reference. Im talking about unforseen and possibly unknown, undetected possibilities that will make the calculatiions conclusions become errant. ( Incorrect and way off ) Would you agree that this is a possibility? Period..You dont have to defend or explain your answer I just need a yes or a no. thx
Then DOCUMENT the rise and setting, record it with photographs. Come back in one year and if the photo you took a year ago does not match up then we will talk. Give me visual proof that should be easy enough for anyone to understand.
This tool provides a web-based limited interface to JPL's HORIZONS system which can be used to generate ephemerides for solar-system bodies. Full access to HORIZONS features is available via the primary telnet interface.
Direct measurements of the acceleration have been only been possible since 1969 using the Apollo retro-reflectors left on the Moon.
The results from Lunar Laser Ranging show that the Moon's mean distance from Earth is increasing by 3.8 cm per year (Dickey, et al., 1994).
The corresponding acceleration in the Moon's ecliptic longitude is -25.858 "/cy^2 (Chapront, Chapront-Touze, and Francou, 2002). This is the value we have adopted in our lunar ephemeris calculations.
Laskar's results still have to be confirmed by integrating the full equations of motion, but this will have to wait until the next generation of supercomputers arrives.
Using this interface, the moon will always be exactly where it is supposed to be because it is a constantly updating system.

So the construction and maintenance of ephemerides which show the position of objects in space for past, present and future have come a long way from the days of a hard-copy look-it-up reference not to even mention a figure-it-out-for-yourself type deal.
Ephemerides or at least the day to day or second to second or even fractional second to fractional second need algorithms and super computers to generate their numbers.
And so it finally comes to a situation where

If you are saying that the orbital parameters are continually updated you are in error.
Continually update and improve the accuracy of the ephemerides using new data and new data types.
We must conclude that not even the hypothesis of Planet X is a viable one to explain the anomalous increase of the lunar eccentricity of eq.
Actually, the values for its mass and distance needed to explain the empirically determined increase of the lunar eccentricity would be highly unrealistic and in
contrast with the most recent viable theoretical scenarios for the existence of such a body.

There is no problem or virus in the link I gave.
As far as your personal computer goes and your "math" comments - read the article. Your questions will be answered.
The link is actually the fascinating story of how our solar system went from being stable to being chaotic. And how now for any final word on anything, we need to wait for the next generation of super computers.
To me, of course, there are and have been easily observable changes in the moon from whatever viewpoints on earth I found myself in. The only difficulty has been in explaining those observations and so thanks OP because this brings a lot of information.

Oh you mean Tycho Crater, and yeah, nice ejecta rays, not exactly the south pole. Now I have an image of a peeled naval orange stuck in my head.
