Globe Vs. Flat Earth
Greek philosopher Eratosthenes seemingly debunked the flat-earth theory with his sticks and shadows experiment in 250 B.C. Celebrated astronomer and cosmologist Carl Sagan endorsed his work many centuries later, proving it was impossible the Earth was flat.
But has their work stood the test of time and advancements in technology? Eric Dubay thinks not. He says Eratosthenes’ calculations were made assuming the Sun to be millions of miles away, but claims we have a “local sun” that is less than a few thousands miles from Earth. Check out his compelling argument on the Eric Dubay channel.
