Just a thought experiment, let’s say the earth is flat, looks like many professionals would know, including

  • Pilots/ATC/sea captain

  • Land surveyor and civil engineers

  • Astronomers and Geologists, at least the one dealing with experimental data

  • Militaries, at least radar operator and artillery

Just these categories are already a lot of persons, I assume I miss a lot of others. So how many person does it make in total ? 10 % of the population ?

    Anybody who has ever flown far enough Eastwards or Westwards and saw how the time of day changed either much faster or slower than the time their clock said it was.

    (Which can’t be mathematically explained for a flat Earth but is a pretty simple effect to explain with a round Earth)

      Forget that. It’s even simpler. Phone someone in a different time zone around sunset. If they say the sun isn’t setting where they are, either the earth is a sphere, or they’re lying and part of the conspiracy.

        If I understand correctly they have some kind of explanation where the sun works like a spotlight or something. But it also requires light to curve in weird ways to make any damn sense, soooo…

          I’m just not quite sure I understand what the point of the conspiracy would be. If it turned out that the earth really was flat, how would it be worth it to lie and say it was round?

          I can’t see any reason for anyone to lie about it.

          Anyway, we know the earth isn’t flat because if it was Trump would have tweeted about it.
