Still waiting on any links to flat earth material on "light bending" or "light bending due to magnetism"? I think i've shown in this post that i'm willing to put the effort in to research flat earth publications, and I've tried searching for info on light bending, but not had any luck.
Without light bending, there's no explanation for the sun setting at different distances. I'm not expecting there to be a fully fleshed out scientific study on flat earth light bending, but at least a vague hypothesis.
