>>21570203>I challenged someone to disprove flat earthReciprocal Zenith Angles disprove the flat earth
On a flat earth, the combined measurement of two vertical angles will equal 180 degrees period
When we do this test on the Earth, it is always greater than 180 degrees and the calculations conform to the accepted value for the radius of the Earth
