The Antikythera mechanism — a 2,000-year-old geared sky computer

The claim

“The Antikythera ‘computer’ is fake or a toy — the gears couldn’t really mesh.”

What is true

◆ Refutation It is genuine, raised from a dated shipwreck in 1901 and read today by CT tomography, with about thirty surviving bronze gears whose tooth-counts produce the right astronomical ratios.

What is measured

A corroded lump from a 1901 shipwreck turned out to be a hand-cranked bronze calculator that tracked the Sun, Moon and eclipses with gear-ratios matched to real astronomy, not a toy, not a fake, but proof that predictive, geometric sky-modeling is over two thousand years old.

What would show this is wrong

gear tooth-counts that fail to yield astronomical ratios, or a faithful reconstruction that cannot reproduce the eclipse predictions inscribed on the device. Neither is the case.
