Proof that space has concave curvature...
Photoshop!!!
No, just not letting you stroke your own egos by passing off bad evidence as though it's unquestionable.
The fact that there are good arguments for FET does not mean you have to defend every random thing that gets thrown out. I haven't even mentioned the issues most FEers have, from lens distortion to questioned sources, though the latter at least doesn't seem to be relevant in this case.
The curvature is six pixels worth of cloud. Compressing it isn't going to change that. All that does is give you more freedom with where you put your line with reference to the edges. Look at the right hand side of the compressed image; it's all cloud, no clear view of the Earth. And the left is pretty indistinct too. This is not a good photo of curvature.
Fod god's sake. There are good arguments out there. All you do when you spend all your energy defending nonsense like this is discredit us in the eyes of FEers.
If it's bad evidence then prove it. Prove that clouds are conspiring to cause the curve.
You're the math wiz, show that clouds can vary in altitude by 6 pixels at 650km with a 35mm lens. Spoiler: they don't.
Just because this isn't the greatest image doesn't make it bad evidence.
Neither does your nitpicking about clouds.
While clouds, atmosphere, and space can be blurred in a high altitude image one thing is not. Their colors.
Those of us with programs more advanced than mspaint can adjust color levels, brightness, and contrast to make things clearer.
It puts the one pixel variance on the ends in perspective.
Simple color brightness and contrast adjustment.
Of course this makes
horizontally compressed images clearer and shows the curve to be more than 6 pixels.
The image shows a slight curve as it should.
There doesn't seem to be any barrel distortion but that can be checked and I imagine soon will be.
So unless you can prove that the clouds are going to amazing heights
in a conspiracy to make the earth look round, I'd say this is not bad evidence.
Not the best but it shouldn't be so blindly dismissed.
It also shows that a little kid can do what no flatter on this forum has the balls to do.
