In July 1518, a woman in Strasbourg began dancing in the street and could not stop. Within a month, by contemporary accounts, hundreds of others had joined her, some dancing for days until they collapsed, and chroniclers reported that a number died. The episode itself is thoroughly documented. What historians still argue over is why it happened.

The most consequential surprise attack in American history, and the one where codebreaking, bureaucratic rivalry and hindsight collide. The mainstream case is intelligence failure, not conspiracy — but the debate has never fully closed.

The claim that a hidden planet, 'Nibiru' or 'Planet X,' is speeding toward a collision with Earth — an idea that began with a single self-described alien contactee, borrowed a real ancient name, folded into the 2012 panic, and has resurfaced under new predicted dates ever since, each one passing without incident.
