The “Flat Earth” Theory

This issue was solved long before our journeys into space began 65 years ago.  Yes, the spherical shape of the Earth was proved 2000+ years ago by the ancient Greeks, but understanding that requires some fluency with high school math, which many Americans lack.

I’m referring to telephony, that spread around the globe in the late 19th Century.  Someone in say, South Carolina, can call a friend who lives on the West Coast and ask about the sun’s position in the sky.  Try to explain the discrepancy if you believe the Earth is flat.

Why would we need 24 different time zones, each 15 degrees apart?
