I would like to have this discussion, but we seem to be drifting. I think we should establish each point to a certain degree - to certainity if possible - before moving to a new point. Otherwise, we risk a sort of gish gallop.
It was posited that shadows do not shrink. When I saw this, I said, aha! I've done this exact experiment! I was able to find a link that shows how to do the experiment; it's simple and quick. Given there are variables of light source size and distance between bodies, can we agree that shadows can be smaller than the object throwing them?
Next, we are considering ethos, or credibility. I believe you are advancing that a gentleman on Youtube has more credibility than Aristotle, or anyone else in the last 2,000 years (no astronomer in that time, regardless of civilization-to my knowledge-has posited a flat earth...unless we credit Samuel Rowbotham). And it seems that you are denying that there is technology that has entered and explored space or the moon--claims which I find credible. So, due to this great gulf between us, what is our criteria for ethos? I have begun the discussion by removing ethos insofar as I am offering that we do experiments we can verify ourselves such as shadows and observing the lunar eclipse. Here, we stand on our own ethos and can share results, if we decide to trust each other.
Regarding the "black sun", I have heard this offered before and done experiments to replicate the effect, but have seen no success. I have neither read nor seen demonstrable evidence (we are speaking of a lunar eclipse here, but, if I understand Matthew correctly, he posits that same body causes the solar eclipse as well). Please, I am open-explain how the black sun works. Is there a way of demonstrating it? Perhaps we can then develop an experiment.
