It may seem like obvious common sense, but in the world of science, there is no such thing. I mean, its obvious that the sun, moon and stars revolve around the flat earth, right? This is what we see every day. This "common sense" doesn't fall apart until someone starts doing the calculations.

I could well be wrong in my assertion that Stuart originally had the causation backwards, but unless someone runs the numbers, there's no way to be sure. Personally, I'd rather see the numbers and know for certain I was wrong, than proceed forward without certainty that I'm heading the right direction.

aaaaaa-men.
