thanks gulliver, i have been looking at the forum for a while and i know that everything he says has been shot down a dozen times. and also, perspective will happen in both a round and flat earth, so it has ne relevence here, and also, the sun doesnt get smaller, it just vanishes below the horizon. either this is because it gets to a certain point and then flies away at the speed of light, or, maybe, just maybe, it disapears beehind the curvature of the earth
