From what i saw of the video,
What also is not explained inn the video is why is the sun setting at all?
I see a video of the sun sinking below a horizon( with refracted mountain tops showing, just, and i do mean, just higher than the sea horizon.
Perspective does not explain why you can see the sun clearly sinking further and further down. It is clearly not at any “vanishing” point, more a “sinking point” i.e. Horizon of the GE.
Also not described addressed is why only the very tips of the mountains are seen.
If the mountain is on a flat earth, the mountain will be seen in its entirety. Clearly there is a large amount of magnification used in the video, so why did the magnification not magically “restore” the full mountain? Why is the bottom of the mountain not seen? If the top is not beyond the vanishing point, the base cannot be either.
It cannot be waves either, as there are no waves higher than the observers position.
Refraction is always present, and has been explained, and indeed is even done so in EnaG, but strangely ignored in his New Bedford farce, but addressed in others.
Standard refraction is exactly as it sounds, under normal conditions, it occurs, and is about 45 minutes of arc with the sun at low altitudes.
This is routinely accounted for in navigation as we take the time of sunset to be when the suns Center is on the celestial horizon (note that is different from the visible horizon due to....refraction) and has the hour angle is 90 degrees(or simply put the longitude difference from the observer to the meridian where the sun is) for practical purposes, this is when you can see about 2/3 the diameter clear between the suns lower limb and the visible horizon.
If anyone is interested here is a simple explanation of the way to calculate it, and it would be easy enough to use the example to calculate the bearing of sunset or sunrise from your location on the earth.....
