Could either of these Rubik’s Cube prodigies solve the cube in 26 moves?

Since the early 1980s, when I got my first Rubik’s Cube, I’ve never been able to solve it. Oh, sure, I got one side done, and maybe even two. Or, I could break the thing open and put it back together in its original, solved, position.

But now, according to the BBC, a supercomputer has determined that a Rubik’s Cube is solvable in less than 26 moves, regardless of the starting position. So, boy, don’t I feel dumb?

It turns out, thanks to research done by Northeastern University graduate students Daniel Kunkle and Gene Cooperman that that’s all it takes to solve one of the famous toys. Duh.

Yet, I wonder: Could the computer that proved this beat the likes of Leyton Lo, who last year set the world’s record of 11.13 seconds? I sort of doubt it. After all, have you ever seen a supercomputer try to turn a Rubik’s Cube?
