The number of possible chess games is greater than the number of atoms in the observable universe

🤷 This changes nothingFact Battle

The Shannon number — named after mathematician Claude Shannon — estimates the number of possible distinct chess games at around 10¹²⁰ (a 1 followed by 120 zeros). The number of atoms in the observable universe is estimated at roughly 10⁸⁰. This means there are 10⁴⁰ times more possible chess games than atoms in the known universe. Even if every atom had been playing a unique chess game since the Big Bang, they would not have covered all possibilities.

Why this is surprising

A game played on an 8×8 board with 32 pieces contains more possible states than the universe contains atoms — the complexity of chess is literally astronomical.
