500 years ago it was well known that the Earth was not flat. Indeed it was known 2000 years and Eratosthenes (another name perhaps not well known to youngsters here) measured its circumference.with surprising accuracy. > > About 500 years ago the Earth was flat and stand in the center of our sol= ar > system.
