Part 8/12:
Polaris and Star Positions: If the Earth is truly flat and connected via a 4D loop, Polaris should be visible from the south, but observations show it is not. If the Earth were cylindrical, Polaris would appear on the horizon for all observers, which is not the case.
Flight Paths and Distances: The model suggests that flights across the Southern Hemisphere would require speeds beyond current aircraft capabilities if the Earth were truly flat and circular. The looping dimension attempts to explain this but introduces further complications when considering North-South travel.
Physical Limitations: The model admits flaws, such as why certain star patterns appear rotated or why star speeds vary between hemispheres—all unresolved by the 4D looping hypothesis.
