Lunar Orientation
Q: Why does the orientation of the moon look the same to everyone one earth regardless of where they are?
A: It doesn't. The orientation varies depending on your location on earth. In FET this is explained by the different observers standing on either side of the moon. On one side it is right-side up, and on the other side it is upside down.
Imagine a green arrow suspended horizontally above your head pointing to the North. Standing 50 feet to the South of the arrow it is pointing "downwards" towards the Northern horizon. Standing 50 feet to the North of the arrow, looking back at it, it points "upwards" above your head to the North. The arrow flip-flops, pointing down or away from the horizon depending on which side you stand.
The lunar orientation varies depending on where you stand on a Round Earth as well. Here is the RET explanation for why the moon turns upside down when you stand on either side of it: http://web.archive.org/web/20070218184023/http://www.seed.slb.com/qa2/FAQView.cfm?ID=1137
This is a quote from the wiki about how we experience moon phases.
https://wiki.tfes.org/The_Phases_of_the_MoonFirst off, I think there should be a way to empirically test this theory by having two people stand several thousands miles apart, on the north and south sides of the earth and observe a crescent moon. According to FET, if you observe the moon from the north, it will be flipped in the south and vice versa. Please read the wiki for an explanation.
FET backs up this claim by suggesting that you would notice a similar effect in RET. I propose this to be false. I do not believe there would be enough difference on a RE for the human eye to notice the angular change from standing on one side or the other.
In fact, (in theory) if you have someone standing exactly on the North pole, and someone else standing exactly on the south pole, the angular difference in their perspective of the moon would be the diameter of the earth (7,917.5 miles), and this angle works out to be about 1.9 degrees difference when the moon is 238,900 miles away. If the two people are standing closer together (which is more realistic), the angle gets even smaller.
Would the human eye actually notice this difference?
If the earth is flat, and two people stand the same distance apart as in RE (7,917.5 miles), and you assume the sun to be 3000 miles high, the angular difference between the observers becomes 105.68 degrees.
Would the human eye notice this difference? You'd have to be blind to not notice. That's enough of a difference that each observer would be looking at different sides of the moon. Which is why the wiki explanation says the crescent moon should flip when being on one side compared to the other.
This should be a testable, and verifiable theory. Does the reflection of the sun off the moon flip when standing on one side or the other?
