Trixie frowned slightly. She hadn't actually said a theory was a fact. She had distingushed that bit earlier. "I know sir" she replied with a smile. "I was implying that once a theory had been to a certain extent, proven to be correct, well then could it be considered a fact?" she asked. "Could I use another example? Perhaps that will help me and others understand better?" she asked. "The theory of Evolution" she stated. "It has never been proven to be correct and in fact it probably won't ever be. Science is a complicated matter but even if we are able to provide evidence to this theory, which we can, would it still remain a theory forever? So therefore a theory is basically a scientific explaination and observation that even when provided with evidence, simply cannot be proved?" she asked.
