In the 1800s through the mid 1900s, hollow Earth was taught with greater emphasis than standard solid Earth. Both were global, because science has for a long time known that the Earth isn't flat.

How do explain the fact that you can only see the tops of the buildings? Why can't you see the entire buildings? Could it be that the view is blocked by a curved Earth?

FTFY

Again, you have the effect of refraction backwards. Atmospheric refraction causes objects to appear higher than they are, regardless of flat earth or globe earth. On a globe earth, refraction can make things that are below the horizon appear above the horizon.

Anyway, I don't think refraction would have any effect on the visibility of objects on a flat earth. Why does it?

Also as a side note, I think some people misunderstand what a zoom (or more precisely, a telephoto) lens does. It doesn't allow you to see farther. Rather, it just magnifies the image. Even though they are the same distance away, you don't need a telescope to see the moon but you need a telescope to see a small feature on the moon.

The horizon line is at the vanishing point on a plain.





Get a grip on reality, the Earth is flat.

^^^ The horizon line is comprised of objects on the plain converging at your/camera center of vision, this central point called the vanishing point is where objects are too small to be resolved and vanish (spread out into a line for all objects in the field of view). If the viewers perspective is raised then the viewing angle is increased and objects appear taller and thus can be resolved pushing the vanishing point further off into the distance.

Now what's going on in that image is the atmosphere that's full of atomized water droplets forms a compound magnifying lens and the buildings that normally would be too small to resolve are greatly enlarged so that they are visible, however their vertical position remains unchanged and the bottoms get masked off by the much closer vanishing point forming the horizon in front of the greatly enlarged buildings. Everything below the horizon line is physical water/land and forms an opaque barrier.

This is also the same reason the Sun remains the same size throughout the day, the magnification enlarges the Sun at the same rate as convergence shrinks it where it eventually sets due to perspective. This can be confirmed by filming sunset from atop a very tall mountain during cool dry conditions where, the Sun can be seen shrinking to a point and eventually fading into the haze.

youtube gives so many videos about ppl who believe that ^^
lol,  if you watch few hours from these videos you are near to
an mental breakdown

The sun never shrinks, your brain on the other hand...

Insert quote from notbatman about refraction, reflection, mirage, convergence and other shit mindlessly to argue against literally anything.

Yes they are proof and evidence when you have hundreds of different videos of the same thing from hundreds of different sources and I'm not talking only about videos of the earth from space but also from airplanes, etc etc. You also have 24/7 livestreams of the earth, you can literally see the ISS with your eyes or a camera, etc.
