Responding to the OP:
I believe this an entirely reasonable request. In my time here I have had no one tell me any valid experiments to validate FEH (I have already posted my critique of EnaG, and my main point went completely unchallenged even by the likes of Bishop), and so it should remain under that name until the requisite experimentation has been performed.
I know Lord Willmore often says that he believe in Flat Earth because of the observations he has made, which is completely sufficient for an hypothesis, but I believe that a variety of rigorous tests must occur before the evidence of an hypothesis can be integrated into a theory. Even if the experiments mentioned are to be considered valid, they are not nearly enough to make Flat Earth a legitimate theory, especially because I read none which investigated into such things a Bendy Light, the EA, the nature of Dark Matter, or any of the other vastly important tenets of the hypothesis.
In short, I agree that Flat Earth is a hypothesis, and that the FE'ers would do well to design and perform experiments not just to re-validate those already done but to discover the true nature of the many unobserved parts of the Flat Earth assembly.
