What about it? Flat Earth maps are currently under investigation. If you have some data to contribute I would suggest starting a formal thread to collect such information to share. *
The contribution is that the investigation on the Flat Earth maps can conclusively end thanks to the airline data provided here and accessible online. Because of this data, all current Flat Earth map proposals are known to be false. Not slightly off, not an approximate representation, but fundamentally flawed. This is a significant contribution to help the members of this forum and society discover and accept the truth about the shape of the Earth. The data and it's application is not presented to antagonize or mislead, it is presented as factual information that help us accept truth and disregard falsehood.
*emphasis added by myself
Not all map possibilities have been considered. There is no accepted Flat Earth map. There are only proposals which have been made by a few people, with no attempts at accuracy except to show basic features of the model.
In order to prove a Flat Earth wrong you will need to show that it is impossible to make a Flat Earth map. You will need to find logs of all airline flights, map all continental distance and layout possibilities under monopole and bipole models, consider that there are many airports which do not have direct nonstop routes between each other, look into jet streams, and study flight delays which are said to happen to 25% of all flights. And only then, once thoroughly investigated, can you claim that there is no possible Flat Earth map. I expect nothing less from someone who declares any map to be impossible.
OK - so if I did that - you'd believe me?!?!
If you'll promise to accept this as definitive evidence of the impossibility of the Flat Earth - then I'd be more than happy to undertake that work! I already have the means to do it (I write flight simulator software for a living) - and I have nothing else important to do next weekend.
All that is necessary is to produce four cities in a rough square with non stop flights between each one and the other three. This will make up a quadrilateral with two diagonals. If the world is flat then the diagonal distances will be geometrically consistent with the length of the four sides and that fact can be trivially demonstrated with geometry that's been known since the Ancient Greeks.
If the world is round, then the diagonals won't agree.
Would you really accept that evidence?
That sounds like a good project and use of your time, far better than just complaining all of the time.
You just fell short of saying that you'd accept this as evidence.
Will you accept such a demonstration as "proof" - if you will, then I'll do the work. If you won't, then it's a waste of my time.
* I pick four cities.
* I find widely published flight times and distances between them.
* I construct a quadrilateral from those distances.
* I calculate whether the diagonals "fit" to within a reasonable degree of error.
If they do, then I'd be forced to admit that the earth was flat.
If they do not - then you'd be forced to admit that it's not.
So...what's your answer - would you accept this methodology?
