Australian Mathematicians Debunk 'Infinite Monkey Theorem'

(Friday November 01, 2024 @12:41PM (msmash) from the tough-luck dept.)


Australian mathematicians have proven the famous " [1]infinite monkey theorem " impossible within the universe's lifespan. The theorem suggests monkeys typing randomly would eventually produce Shakespeare's complete works. Scientists Stephen Woodcock and Jay Falletta calculated that even 200,000 chimpanzees typing one character per second until the universe's heat death [2]would fail to reproduce Shakespeare's writings .

A single chimp has only a 5% chance of typing "bananas" in its lifetime, with more complex phrases facing astronomically lower odds. "This finding places the theorem among other probability puzzles and paradoxes... where using the idea of infinite resources gives results that don't match up with what we get when we consider the constraints of our universe," Associate Prof Woodcock was quoted as saying by BBC.

You can do it with 1000 moneys in a finite amount of time. It's much, much longer than the lifespan of the universe, but you can pick any probability and number of monkeys and the time will be finite. Presumably they did calculate it and that's what the actual story is about.
