Higher mountains can appear lower because of a such well documented and easily verifiable phenomena as perspective. Objects appear smaller the further away they are situated. The fact that we can see a mountain as far away as 443km on the original photo suggests that there is no 5km tall obstruction created by the supposed physical horizon.
Your claim is - air layers of different temperature, pressure, humidity bend light around the supposed Earth’s curvature. To provide proper evidence of it, one needs to visually showcase it and include measurements of air layers through which the light passes. All the documents you sent me objectively lack the needed air layers measurements. That is not debatable. It is you yourself who has a strongly held belief and disregards the fact that there seems to be no real world evidence proving your belief correct.
In my book, any theory that cannot be proven to exist in the real world is just a wet dream of whoever came up with it. People are free to believe in fairies, unicorns and whatever they wish, but I will not consider them to have anything in common with real life unless I see properly documented evidence.
Thank you for the link and your continued desire to help me look into things, I truly appreciate it. However, this link as well provides exclusively theoretical suppositions and completely lacks all the relevant air layers measurements needed to prove refraction can visually bring objects up in the air to the tunes of many kilometres.
