You would think, wouldn't you, Mr Red, that I hadn't mentioned caveats re wobbles and topography in my post. Clearly, you've been taking lessons from Donuel in fanciful obfuscation (though not in science). Perhaps you could explain why predictions of future eclipses have been so devilishly accurate for many decades, if not longer. Then work back and tell me how "chaos theory" might have confounded calculations of past eclipses. Plenty of very sound science is possible without your "having to have been there." I thought you might have known that, or did Donuel tell you different?
