The universe is awash with strange radio signals, but astronomers have now detected a really bizarre one that repeats every hour, cycling through three different states. While they have some ideas about its origin it can’t be explained by our current understanding of physics.
Well, if it’s been running for a long time, it’s up to some random point in pi and we missed the start. But we can still try to interpret the signal as digits, and check if this sequence appears anywhere in pi… Well what do you know, it does!
(disclaimer: it has never been proven that π has this property, but it is suspected)
Don’t worry we can check the library of babel for the answer.
