People have known earth was a globe for 2500 + years , not sure where your coming up with 500.
Just because Eratosthenes said the earth was a globe in 350 bc doesn't mean the entire world believed it or knew it.
Second of all lf there was no twitter or published newspapers back then, and the Library at Alexandria was destroyed and there is no surviving copy of any of his assumptions.
Thirdly if everyone knew the earth was a ball of 25,000 miles 2500 years ago - then why did it take them 2000 years to go a find it? Its a nice story but i wouldn't put my absolute faith in like you do.

Still waiting for him to tell me how much an object would be obscured over a 90 foot distance if it were seen at an angle parallel to the ground, from ground level.
Since the pythagorean theorem for the supposed curve of the ear is 8 inches per mile squared but since this is actually the amount our perspective is affected - i'm guessing since 90 feet is .017th of a mile - the answer would probably be in the thousandths of an inch.
Still waiting for your joke of an experiment though, im sure whatever you do will be wrong.
