You guys and your equations. You guys are happy to follow a lie with complex equations. The whole damn moon landing is a lie. They give you a fairytale, back it up with numbers and equations and you think you understand everything.
Equations bring concrete evidence. If you have a theory, specially a cosmological one, you will pretty sure need equations to support it and make predictions about it. If you as a flat earther are bringing something new to the table that is an alternative to the actual theories and laws about the universe, including physics, chemistry, aeronautic, just to name others... then yes.. you NEED to have equations and math to back it up. Until then, your case is lost frmo the very beginning.
