I have a query about this picture.
Ok, as we can see, half the buildings disappear and this is attributed to the curvature of the earth, right?
Well here's my problem with this.
If that is the case, we also are told that the earth is round, so it should curve from right to left but that line looks perfectly straight, yet my real query is.
If the buildings disappear by half, over that distance, then they should also angle away from each other, for instance, they should be slightly leaning left and right from that distance, also.
They may be spirit level straight up when your a mile away or a bit more, but not from that distance. Any reason why they are bolt upright, if the earth is a globe?
The buildings are leaning but not to the left or right. They are leaning away from you. But of course we cannot see that from a 2-dimensional picture.
And also, a lens does not have the same angle of view as your eyes. While your eyes can see horizontally with an angle of view of 180°, a zoom lens can only see a smaller portion of that. The more powerful its zoom factor, the smaller its angle of view will be. Assuming that you reach an altitude high enough to see the below curvature, your lens still cannot see the same curvature. You need to go much higher for your lens to be able to see what your eyes can see at a lower altitude.
