    Atmospheric sunlight refraction arguments on the Eratosthenes triangulation method

    DarkStar presented his measurement using the Eratosthenes triangulation method to prove the globe earth model curvature is right. http://flatearthinsanity.blogspot.com/2016/07/simple-proof-for-convexity-of-earth.html Here is the heart of the proof. Simply pick a line of longitude (along which...

    Earth curvature refraction experiments - debunking flat/concave Earth

    I keep being presented with 'earth curvature experiment' videos recently, by flat/concave earth advocates. It seems to be their new favorite "evidence" that Earth is not spherical. Debunking this gets into math which I stink at, regarding refraction. I would like to be sure I have considered...
