Since you dishonestly "refuted" Black Swan obviously without watching it, repasting the same trash from a previous thread (where, BTW, it's obvious that in the first image, the waves heights are higher and therefore obscuring the bottom of the platform), I post the key images from Dr. John D here. There was lengthy video of the whole thing and all the numbers were given.
This is a view of windmills out at sea between 8 and 11 miles away from the observer.

I'll post the picture in a minute where here he lists the distance of each one.
These get gradually lower and smaller/shorter exactly as one would expect from perspective without any refraction whatsoever. In order for that to happen, every single one of these would have to be refracted at the exact same rate and in the exact same degrees. So 6 would have to refract to 5, which would refract to 4, etc. ... all with IDENTICAL degrees of refraction. So the angle of refraction between 6 and 5 would have to be the same angle as between 5 and 4, and 4 and 3, and so on. If they angles were off, you wouldn't get this perfectly proportional perspective effect. They're all at the same height above sea level. And they're all in the same "atmosphere layer". If a higher layer of atmosphere were hit, and it were less dense, then the light would refract up, and make it LESS possible for the observer to see it than globe curvature would. And, on other pictures, you can see that the different points on the turbine all the way to the top, from the propeller dynamo housing to the tops of the actually blades, are all equally-proportionally smaller / shorter / closer to sea level as they get more distant. So the degree of refraction would have to be perfect from top to bottom. And then also the horizon, which is visible behind the farthest one, from well over 11 miles, that too would have to have been "refracted" over the top.
Globtards pull "refraction" out of their posterior as the gratuitous answer for all such pictures, without doing any math or analysis whatsoever. That's because they simply refuse to consider the possibility with an open mind.
So, again, the two-way laser experiment, which you undoubtedly also didn't bother watching, absolutely devastates refraction. You would have to have a continuously increasing density gradient all the way there. But, then on the way back, you would by definition have a continually DECREASING density gradient, which would not only NOT bend the laser beam down, but would in fact bend it even higher, in the other direction. Two lasers going in opposite directions at the same place and same time cannot both be seen from the other side. That puts the nail into the coffin of your precious
deus ex machina to save the globe earth.
