if you travel along a line of latitude of some angle above the equator and then the corresponding line south of the equator between two separate and fixed lines of longitude, then on the globe you travel the same distance but on a flat earth the path along the southern line of latitude is necessarily longer. This is verifiable with renaissance era technology, so this experiment can easily be done. Do FE adherents think that navies and coast guards prevent this experiment from being conducted and reported on? Do they think there is some contraction of space that happens outside the ring of the so-called equator if you will that accounts for this? Thanks, not sure how to post the image I drew of my question.
