It is claimed by one Fe'er, Tom Bishop, that this is simply a natural illusion derived from Snell's law.
Mr. Ireland, I appreciate you standing in for Tom Bishop.
Well, I know Snell's Law really well. And unless Tom knows about a medium other than air that I was looking through, I'm not buying that explanation. Oh, and Tom, would you mail me a piece of this special glass or plastic or whatever that has these amazing adaptive, even predictive, diffraction indexes? I'll file all the paperwork and share all the patent rights. I'll give you 99.99% of the net and retain .01%. I'll be rich.
Oh and I thought Tom recently chimed in that it's the curved edge of the Sun's spotlight that accounts for the apparent curvature of the Earth. I didn't buy that one either.
It seems a theory as old as FE would have a consistent answer to basic questions like this. Any word on the FAQ update, folks?
Inquisitively,
Gulliver
