MY POST WITH THE ALTERNATE NEWTONIAN VERSION WAS TO PROVE THAT RELATIVITY IS AN ABSOLUTE PILE OF CRAP! THE KINK CONTAIN INFORMATION ABOUT THE DERIVATION OF "A CASSINI'S DELAY FORMULA CLONE", BUT IT'S BASED ON BLACK HOLES AND PHOTONS, AND IS A SAMPLE ABOUT THAT ANY IMBECILE WITH SOME MATH SKILLS CAN DERIVE THE SAME RESULTS AS PURE BREED GR RELATIVISTS. THE DISMISSAL OF THE IMPACT OF OPTICAL PHENOMENA LIKE REFRACTION IS NOTABLE. PLUS, ANY OF THESE FORMULAE CONTAIN FOUR ASTRONOMICAL DISTANCES TO VENUS OR MERCURY, DATA THAT (STILL TODAY) CONTAIN IMPORTANT UNCERTAINTIES, BEYOND ERROR BARS. ADD TO THE ABOVE THAT c IS FIXED BY INTERNATIONAL CONVENTIONS, DUE TO THE DIFFERENCES BETWEEN LABS WORLDWIDE MOUNTING UP TO +/- 200 KM/SEC, AND YOU HAVE AN INTERESTING CONTEXT OPEN TO FRAUD, FUDGING AND COOKING DATA. NOT TO MENTION THE HUGE AMOUNT OF PERTURBATIONS, NOISE AND PULSE DISTORTIONS THAT REQUIRE COLLECTING DATA BY THE THOUSAND AND POST-PROCESSING IT WITH DUBIOUS ALGORITHMS. GO BACK TO YOUR GARDENING HOBBY. IT SUITS BETTER FOR YOUR MELTED BRAIN.
