Fun Fact: Any Rubik's Cube Combination Can Be Solved In 20 Moves.

You tellin' me that this whole time it only takes 20 moves?!
In case you didn't already know, it took the brilliant minds of researchers to finally crack the codes on how many moves it takes to solve the mighty Rubik's Cube. I believe the real story here is that there are researchers being paid to figure this stuff out..... Who's funding these guys? Seriously!?
The international team used a bank of computers at Google to help crank through the solutions. The figure is known as "God's number" because an all-knowing entity would know the optimal number of steps needed to solve the puzzle. "We now know for certain that the magic number is 20," Professor Morley Davidson, a mathematician from Kent State University, told BBC News. The results suggest that there are more than 100,000 starting positions - of a possible 43 billion billion - that can be solved in exactly 20 moves. However, the majority of solutions take between 15 and 19 moves to solve.
 ...or, you can remove the stickers and re-stick them back to......Nevermind.
