Just a simple guide on how to test for measurable curvature across earth. Works over land and sea!
Obviously water has never conformed to the exterior of a sphere in our reality (excluding photos/videos from trustworthy government agencies) using the scientific method we all know liquids to seek a flat level.
Please don't get mad and hateful just look at this using the scientific method and try to debunk it or show a better test to prove the earths curvature. Thanksssss
