ITT: I hate narcberry so much.
This is a completely valid argument against FE. The refraction has nothing to do with it because even without it in the equation, the direct result is that the Earth is round (but with a different diameter). As I have said numerous times before, FE defies the commonly accepted models for physics and geometry (i.e. perspective). Is it really so much to demand that some FEer stops arguing about the accuracy of the website's calculations and simply explains why we see such an effect at all?
