Hmm, I think we may be on to something here. He have already proven that the buttered-cat will not land, but instead will float. Well since the cat exists in all dimensions simultaneously, it follows that the buttered cat must 'float without landing' in all dimensions. In other words, we have unlocked the secret of time travel!
Also upon observing a cat walking into a beam of sunlight, it is immediatly rendered helpless, and unable to move. It is clear from Darwin that such an characteristic could not have evolved in a light filled environment, so the cat must have evolved before light existed. Therefore I propose that naturally-occuring buttered cats existed before the big-bang.
