Great post Mr Gamb00ler. Even at my age I'm still willing to learn.
For me, this topic is somewhat a barometer. I started off thinking that the earth could be round, and then, I read @rattlesnakeand because he certainly knows his stuff, the pendulum swung; and I was 50/50. Then @richard_smith237posts. His arguments were/are very convincing and I went 60/40. in favour of a round earth. But!! The pics Rattles put up are the nuts. So I'm now 40/60.
If someone could tell me why a plane can't fly round the coast of Antarctica, it might sort it for me. Or/and, if we drilled a hole through one ocean, say the Atlantic, would all the water pour through it? Into where? Outer space? Maybe inner space!
It's a complicated subject alright.
