Something else that occurred to me just now! Well, they say that the Earth is an oblate spheroid which means that the polar regions are literally flat. Have they tested the horizon visibility distance there? There is virtually zero humidity(it's the driest place on Earth), so a perfect place for long distance observations. They claim that if the Earth were flat you would be able to see stuff very far away. It is actually given as evidence that the Earth is not flat, because supposedly objects sink below the horizon. There is even a formula which calculates this. Can you see 1000 km away in Antarctica then? It is flat, right? Even they say so If you can't see so far away, doesn't it mean that the reason objects sink below the horizon has nothing to do with the curvature whatsoever? The shape of planet EarthOblate spheroid

The shape of planet EarthOblate spheroidThe earth bulges at the equator by 26miles which by definition means it is an oblate spheroid. I was just reading an article that says it bulges by 21km though so even less. I am assuming i do not have to explain further why the polar regions are not flat?

I guess it is a general misconception that the polar regions are generally flat.

I have been moving a huge amount of granite from my place and it often comes to my mind that i am creating a distortion in the local gravity field. One of the reasons i am here on this forum is i am totally knackered by this work. It is probably an obvious thing but Granite is very hard and very heavy. It can also be dangerously sharp. Almost beginning to hate the stuff!
