The Paradox of the Surprise Executioner takes the classic 'unexpected event' idea and twists it through the logic of time.

If your fate is sealed and the date is fixed, why can't you figure it out? And if you can figure it out, does that destroy the surprise — or the future itself?

This paradox challenges how we think about determinism, prediction, and the very structure of time.

Sometimes, the scariest thing isn’t what’s coming — it’s knowing you’ll never see it coming.
