Using computers they borrowed from Google, an international team of mathematicians has discovered that every Rubik's Cube can be solved in 20 moves or less.

Related Fact: The fastest anyone has solved a Rubik's Cube blindfolded is 30.94 seconds. Haiyan Zhuang of China set this record at the Xi'an Spring 2010 Rubik's Cube competition.
