So i have just read all of this and i still dont have a definitive understanding on how the flight paths work.. between australia and south america... can i have more info and also as a newbee why do we advocate the flat earth and debunk the round earthers but yet they are the only ones that can supply a true map of the earth or at least a satellite image that we say is not true... why dont we provide them with the true satellite image of the word being flat...
I'd start out by saying I don't believe the earth is flat.
But the answer to your question is because, simply, there is no map of a flat earth which corresponds to the world you see around you. No-one in the FE community seems particularly interested in building a model of how the world works which ties in with actual, observable data - such as distances between places, flight times, the shape of places, countries, islands, the length of the day and direction the sun appears to be at any given time of the day etc.
Which is strange because if the world was flat, then creating a map of it would be simple, from a cartographical perspective.
Problems arise when you try and project a 2D image onto a 3D surface, or vice versa. This is why all maps of a spherical earth, when viewed on a bit of paper or a screen, are distorted. Look at Google Maps - countries closer to the poles are stretched and appear far greater in area than they are in reality. Similarly the map on this website of the flat earth is hugely distorted - Australia is stretched out very thin, for example.
If you want an example that's easier to envisage, imagine taking a square bit of paper and wrapping it around an orange. By the time you get to the back, the paper is all crumpled up and distorted. Similarly if you tried to peel the orange and form a flat image, you wouldn't be able to. Gaps would appear where the peel has been split open and laid out flat - or you would have to stretch the skin to make it work.
The only time a map of the world actually appears to correspond with reality is when it is projected onto the outside of a sphere. Then, it ties in with things like flight times.
Now, what does this tell us about the shape of the earth?
