|    I don't buy into flat earth because:
|    
|    The time it takes to fly from London to New York to Tokyo to London is significantly shorter than the time it
|    takes to fly Dubai to Miami to Hong Kong to Dubai, and that time is longer than the time it takes to fly Sydney
|    to Sao Paolo to Johannesburg to Sydney.
|    
|    This only makes sense if the earth is round and thicker near the equator. If the earth was flat with the north
|    pole in the middle, the Sydney circumnavigation would be the longest, London the shortest. I can't think of any
|    other explanation.

I am a former broadcast engineer. If the Earth were flat, FM radio stations in Oahu could be heard clearly in
Los Angeles 24/7. But they can't be heard there at all. The signals are blocked by the curvature of the Earth.
Radio broadcast and communications engineering coverage calculations have to take that curvature into account in
order to be accurate. The Earth is not flat.

|    Radio signals dissipate per inverse square law, and due to limited permeability & permittivity of free space.
|    
|    Also, radio signals can and often do bend through free space.
|    
|    Signal in Oahu can't be heard in LA because the signal-noise ratio is insufficient for the receiving equipment
|    to be able to filter.

     The celestial theodolite experiment is hard to reconcile.
     
     It eliminates common variables that tend to be disputed.
     
     It is data heavy so feel free to have an llm break it down.
