I recently talked to a sailor who had spent 18 years working on ships during that time he became very good at spoting ships on the horizon when I explaind the flat earth perspective on how ships diminish in size he told me "No matter how much you magnify the ship it will be blocked out by the curviture of the earth."
It is called atmospheric magnification / refraction. The moisture above the water acts as a lens. As the object on the water recedes it will begin to "sink" from the bottom up. This is elementary science that a sailor will not get from "spotting ships" and not knowing a thing about atmospheric magnification / refraction. For you to cite that reference really is ludicrous. You eyes are lenses. The atmosphere is another lens you are looking through. That's two lenses to view an actual object.
The video aptly explains this phenomena quite well and nothing more needs to be said about such simplicity.
Well I contacted the "Simple sailor" NOT only did he know what Atmospheric Magnification/Refraction was(which by the way he learnt what it was during his time on ships) he also explaind that what you are referring to is NOT in fact atmospheric Magnification/Refraction but in fact Thermal Inversion due to the fact it is over water it is reflected on the water as well as naturaly being a phenomenon that acts at
short range only .
In terms of your video it dose not explain anything thought the guy has some good video splicing skills maybe link the source videos next time.
Also I looked up Atmospheric Magnification/Refraction and Guess what it works on a ROUND EARTH AS WELL hear is a site i found this information on
https://aty.sdsu.edu/explain/atmos_refr/magnification.htmlThe only ludicrous thing here is that YOU assumed someone's level of education by there career.
