>>1470448Well for the first question, I'm not even sure what you're talking about? Eclipses are a result of moon and sun orbit, how is the earth's shape supposed to come into play?
Secondly, it's been known for a long time that gravity bends light to an observer. Earth actually has a rotating gravity well from the back protruding across the rim, which on one hand alternates at the center between "sucking in" and "pushing away" light, for lack of a better word. This results in alternating dark and light periods at the center (which you call the northern hemisphere). On the other hand, because this gravity well protrudes across the rim, it also curves the view of an observer, resulting in what you call the horizon. We see it that way because we can't escape our sense of human perception
