Empirical Earth · The Boomerangs — Flat-Earth Proofs That Backfire
The claim
“Time zones are just a spotlight Sun on a flat disc.”
What is measured
Earth turns 15° per hour, so your antipode is ~12 hours apart. Call them and it’s the dead of their night, on the far side of a ball.
What would show this is wrong
simultaneous daylight at true antipodes, or a lit fraction far from ~50% with no sharp terminator.
