Today I encountered a very bizarre web site claiming to explain the extinction of the dinosaurs using a change in the gravitational constant.
LOL Reading that nonsense really brightened my day. I love the Gallimimus weighing 27kg! That's juvenile you fool! The only effect a meteorite would bring is a climate change!? Non-dinosaurian reptiles somehow staying overadapted to gravity for over two million years..... Absolutely no reason the aquatic reptiles would become extinct..... So many errors..... can't insult all.... ;-)
I'd say don't waste your time sending an e-mail critique David, he obviously isn't using logic to support his arguments.
