Hello everyone!
Hi Mr. God Rules (hm?, I never caught your real name, brother)
I could see that you struggle with this issue in few of your videos, even though you talk about optical illusions in most of them.
In my opinion it is impossible to deduce anything from the pictures if we consider that any lens will somewhat distort the real thing. Another thing is that when you look at all these high altitude pictures they all have the fuzz right around horizon line. That makes it impossible to perceive the horizon as a sharp line we can measure. (Known effect in perspective considerations). Measuring the horizon line that is above the mountains should be discarded right away for obvious reasons.
If the Earth WAS flat, the horizon (we perceive) wouldn't be. We would see it as a (inverted) curve. Ancient builders knew this, and thus adjusted the blueprints to compensate for this illusion: Length-long steps leading to (e.g. Greek) temples are not built flat, but curved in such a way that they APPEAR to our eyes to be a perfectly flat line. In a colonnade that is spaced equally (spanning the whole length) the last one on each side looks like it is further away from its neighbouring column. Guess what they did to fix that? Why, yes, they built the last ones in a row to be closer than the rest and giving the ILLUSION of perfectly spaced columns.
And as for the visual proof of the sphere I will be your witness that only after the sun had long set that you can see the actual curvature of the planet, and it is very gentle curve - just about merely perceptible. I am talking 30,000 feet above the ground view point.
Here's what happens: right after the sun sets we can still see some direct sunlight above the horizon, and that will distort our vision of the horizon line. Once the sun has gone way below the horizon, and the only light we can see (above the horizon) is the narrow strip of the bent sun rays we can finally see the sharp edge that strip of light makes against dark horizon. That is when we can see that gentle curve with a naked eye. Unfortunately, my (old) camera could not capture this scene for the lack of usable light... I wish it could...
Cheers!
