"most people "know" the earth is round only because their teachers told them so, and they believed it!"

Wow, Jim!!! THAT is exactly the point I was trying to make in several of my posts on this thread...good stuff!

Now you've got me wondering if the guy at U. of T. was part of such a put-on. If so, he was willing to keep at it for lengthy periods of time.

If it is a well-organized put-on they ought to get a gold medal award for creative humour. I can readily see how the concept of a flat circular Earth can be used to glibly explain sunrise, sunset, orbital paths of satellites, etc...one wonders what is on the bottom of said flat Earth? Fascinating! We must get Captain Kirk and Spock to investigate this matter and deliver the definitive word on it. :-)
