Ah, the classics.

There are so many ways to approach this one, but at the end of the day it is all a red herring predicated upon a widely educated mistake.

The horizon does not curve at any altitude, because the horizon is not a physical location but an optical illusion. It is the limit of our vision, and presents as a perfectly flat horizontal line that surrounds us 360 degrees. The apparent curve seen in videos/pictures like this is always due to distortion (though the lens itself is only one source).

Because it is not (as we are mistaught) the “edge of the world”, it does not pertain to the shape of it - regardless of what that shape is. It’s as silly as saying that rainbows prove the curved shape of the world (or dome), and for very similar reasons.

The earth and its shape are down here! There is no sense (or science) in trying to get further away from it in order to measure that shape! That literally makes the shape harder to measure and science requires measurement (empiricism) not merely looking! There is very good reason for this - because what we see is often not what is. In the words of obi wan, “Your eyes can deceive you; don’t trust them”.

It’s all red herring and distraction. It’s something you have to get beyond if you want to earnestly penetrate the subject.
