Yes, but no one here is claiming to do science, in the opposite they have strong objections against science and scientific argumentation.
Could some bona fide Flatearther confirm this please? The objections in question are not against the claims of established science themselves, but rather scientific methodology itself, i.e. the method science uses to confirm or disconfirm truth claims. That's pretty important.
I thought that FE did use the scientific methodology, except they come up with different answers.
Let's say they accept science where it is not in contradiction to the "obvious truth that the earth is flat". They throw away many areas of optics, gravity, the whole physics about planetary motion, the mechanism how the sun produces its energy, basically everything in astrophysics and geophysics. There are contradictions to quantum mechanics, the standard model in particle physics, electrodynamics, optics.
Roughly you can say, its a scientific picture like in the early 19th century. With some selective exceptions, e.g. there affinity to the equivalence principle.
Methodically they claim to be empiricists, which they call zetetics. Basically, that means draw conclusions only from direct observations with a minimum of tools and assumptions, just by your senses. Like looking out of the window or jumping from a chair to see how the earth is approaching you. And believe it only, if you tried and experienced yourself.
