Think Rubik’s cubes are child’s play? Maybe so, but they’re also an obsession for computer scientists who specialize in so-called “search and enumeration” problems. In 2007, researchers at Northeastern University proved that no matter what its initial configuration, any Rubik’s cube could be solved in 26 moves.
Of course, how long it takes to make those moves—or to solve a Rubik’s cube using any number of moves—depends on who’s holding the colorful cube. And at the World Cube Association’s Zonhoven Open, held on Feb. 25 and 26 in Zonhoven, Belgium, Marcell Endrey set a new world record for cube-solving. The young Hungarian solved the cube in 28.8 seconds.
That’s pretty fast—especially since he was blindfolded at the time.
Don’t believe such a feat is really possible? Have a look at the video:
