A Rubik's cube has 43,252,003,274,489,856,000 possible configurations.
With 6 colored sides, 21 pieces and 54 outer surfaces, there's a combined total of over 43 quintillion different possible configurations. To put that into perspective: if you turned the Rubik's cube once every second it would take you 1400 trillion years to finish to go through all the configurations. If you had started this project during the Big Bang, you still wouldn't be done yet.
Can you believe that?
