I make no claim whatsoever about how these distances are determined, I'm just pointing out that this flat map from Bing has a built in measurement tool which purports to tell you accurate distances between any two points.
Purports being the operative word.
The fact you cannot confirm it is a measuring tool based on linear measurement might be a good clue...
I don't really care how it works or what it's based on so long as it is accurate. Since I'm on the RE side of the fence, if I'm to believe the tool is accurate, I'm not inclined to believe it's based on a linear scale, but however it works, it's a built in tool being used on an indisputably flat map, which is what you want me to use surely.
What I have shown you is that using this tool in combination with the map gives you paradoxical distances which are impossible to reconcile if you believe this flat map is an accurate representation of reality.
No you haven't.
You said you did, but did that:
1. using lines representing distances that no one would ever be able to independently confirm as they don't represent actual routes of travel; and,
2. personally failing to confirm the type of measuring tool you purport represents reality.
I don't purport or claim anything here. Bing's tool claims accuracy and therefore purports to represent reality. You keep pushing this back onto me and what I claim and make out this is somehow just down to my opinion. I'm just reporting what I find here, if you don't like it then either I've made a mistake and reported falsely what I've found (certainly possible, although I assure you if that's the case, no deliberate intent on my part), or perhaps you don't believe Bing's tool is reporting correct distances, I'm not really sure quite what your position is to be honest.
If you doubt these distances, then you are not doubting me, you are doubting Bing's ability to measure accurately.
Oh no...make no mistake...
I am clearly doubting you also.
Fair enough, can you separate out for me where you doubt me? Have I misreported the distances from Bing? Is my mathematical analysis faulty? Something else?
Then why did you start?
I started because you made a generic claim about all flat maps and their accuracy. You added the requirement for this to be "an actual journey" afterwards. Part of the problem with this is that "an actual journey" is a very vague term and only you really know what you mean by it, I can only guess. Some examples would help.
Examples of what?
8000 km air routes?
8000 km shipping routes?
You definitely know these things to exist.
Sure. OK then, if I can find 4 airports, each with a direct flight to all the other 3 airports and 8000+ km apart, that satisfies the requirement does it?
Next problem is how to find the distances between the airports. I can just use Bing maps or Google maps, presumably that's out of the question, so what's your solution?
It's not my opinion at all. Opinion doesn't come into it, this is maths, pure and simple. The figures coming from Bing unambiguously show an 18% difference between Bing's measured distances and a calculated distance on an assumed flat earth, using pythagoras.
Nah...still just your opinion.
No sorry, not following you. I've reported some findings, no opinions involved. I've applied some mathematical reasoning to demonstrate that these findings lead to a paradox. That's just maths. What opinion(s) do you think am I expressing here?
The logical argument I'm putting forward here is simply this: If the measured distances are accurate then the surface cannot be a flat plane. The proposition (the measured distances are accurate) is either true or false. If it is true and the argument is valid, then the conclusion (the surface cannot be a flat plane) is also true. How is this my opinion?
