Hello,

I have recently heard about tfes and have one key question if I may and it's to do with the curvature of the earth.

If you stand in say Africa or Ireland or anywhere in the world where there is an opposite continent; if one were to use an accurate and powerful telescope, you should be able to see the coastline of the opposite continent.

If the earth was flat, then a telescope observation between continents would surely prove flat earth.

If the earth was round, then the opposite continent would not be observable due to the curvature of the earth; hence why we observe a horizon when looking out to see.

Why can't we conclude this entire theory with one single telescope looking east to west or west to east across a straight line ?

Best wishes,
