    • @AOMartialArts
      @AOMartialArts 2 ปีที่แล้ว +2

      The measurements Eratosthenes took are based on the assumption that the sun is millions of miles away. (The distance of the sun has changed significantly over the last thousand years, by the way.)
      The flat earth model has the sun close to the earth (about 3000 miles) and smaller (about 33 miles wide). The sun then acts like a "spotlight" more than a giant ball of light, and it produces a finite throw of light. Therefore - going back to Eratosthenes- if the sun were directly above the well at Syene, it *would* cast a shadow on the stick at Alexandria.

      @@AOMartialArts You have a point. This experiment of Eratosthenes was not designed to prove the shape of the Earth, but to measure its size. The shape was already well known to scholars at the time.
      If you reject the spheroid shape, and plug the two measurements into a Flat Earth Model, then yes, you could assume a small local sun.
      It should be noted though, that you will get an arbitrary height for the sun entirely dependent on where your two points of observation are.
      Now, with only a small adjustment, you can repeat this experiment in a way that tests the shape of the planet as well.
      Simply increase the number of points that you measure the angle from.
      This causes no issue on a globe. You can add hundreds of points and get consistent results, all pointing to an angular change of 1 degree for evey 69 miles.
      If you try to make 3 or more observations work under the Flat Earth Assumption it falls apart.
      If you have three different angles and you try to plot the suns height as where a pair of lines intercept, you will find yourself calculating _multiple_ positions for the sun.
      It gets worse, very quickly the more points you add. So, yeah, strictly speaking, Eratosthenes method with two points doesn't prove a globe Earth, but with 3 or more points, it completely contradicts a flat Earth, and fits with a spheroid Earth.
