If the discussion regarding the shape of the Earth interests you, today I present an experiment of which the results would vary widely depending on if we are living on a flat Earth or a spherical Earth. In the spherical model, the Moon is ~238,000 miles away and over 2,000 miles in diameter. In the flat model, the moon is 3,000 miles away and 32 miles wide. I misquote these numbers in the following video, but the point of the experiment stands nonetheless. Enjoy.
I still believe the Earth is almost 100 million miles from a ball of hydrogen fusing into helium, but I would not lose sleep if this experiment proves to me a flat Earth. If the moon is 3,000 miles away, somebody standing under the moon would perceive it twice as large as somebody 6,000 miles away. If it is 238,000 miles away, it will appear the same size everywhere on Earth to our eyes.PS Jeff, Anarchapulco was a great experience this year and I will definitely be attending in 2018. Thanks for everything!
