An interesting video about the stars slowing down as they approach the horizon. At the 1:15 mark the author states that "the stars get significantly closer together as they get closer to the horizon."
This contradicts the Round Earth Theory that says that the celestial bodies move at a constant speed across the sky as the earth rotates.
Please show where "Round Earth Theory that says that the celestial bodies move at a"
precisely "constant speed across the sky as the earth rotates."
Now read and study all of
Lecture 1: Introduction to Astronomy 250. Especially the section that starts with:
When making precise measurements of stellar positions, various effects must be taken into account:
- Aberration -- an object's position will be shifted slightly because of the finite speed of light and the observer's motion
- Refraction -- light gets bent (refracted) by the Earth's atmosphere, a star's altitude is increased by refraction. When the Sun is setting, it is actually beneath the horizon when its lower limb just appears to touch the horizon -- in other words, the refraction amounts to ~35', the apparent diameter of the Sun. Refraction depends on your altitude, the atmospheric conditions, and the wavelength of the observation.
The official Round Earth excuse is, of course, that there is a permanent mirage effect that slows down the stars, and which also reverses any observation that suggests a Flat Earth.
Sure, you call it an excuse but the deflection of objection near horizon has been observed for around 2 millennia.
Abstract
Astronomical refraction has had a long and fascinating history. Cleomedes (100 A.D.) and Ptolemy (200 A.D.) were aware of its existence and understood in a qualitative way some of its properties. Alhazen (1100 A.D.) quite correctly suggested that the flattening of the sun’s disk near the horizon was due to astronomical refraction. Tycho Brahe in 1587, however, was the first to make direct measurements of the magnitude of the refraction.

So I would say that your claim that this slight variation due to long known refraction "contradicts the Round Earth Theory" is totally without foundation.
Not only that, but you claim "The official Round Earth excuse is, of course, that there is a permanent
mirage effect
<< emotive term for 'slight refraction' >>" yet your own "Flat Earth Society Wiki" uses
refraction to explain "Horizon Limits".
Horizon Limits with Refraction and Opacity
Horizon limits are easily explained by the fact that air is not transparent and refraction. As light travels through a denser medium, the object will appear to be smaller because light is refracted towards the normal. Furthermore, air is not transparent so it is not possible to see past a certain distance.
So this seems just another "strawman augment" from someone who has an imperfect and incomplete knowledge of so-called "Round Earth Theory".
