Except that it doesn't. You COULD just go take a theodolite app and MEASURE the actual horizon dip... as surveyors have been doing for years, and that you could do for free with an app and a tall building... but you won't.
You do realize that science invented specialized instruments to actually prescisely MEASURE the horizon drop a hundred years ago, right?
And we are so technologically advanced from this SAME science, that you can have a scaled down version of this prescision instrument at your fingertips if you wanted to. For free.
But you obviously are not interested in the reality that anyone can measure the horizon dip and see for themselves. You are more interested in maintaining a ridiculous delusion.
Don't trust those evil technological advances? Hey, you can even use and old school leveling rig and see the horizon dip for yourself.
I'll bet you wont'.
