Using 35 yr of Google - donated processor time , a squad of researchers found that every possible form of the Rubik ’s Cube can be solved in 20 moves or less . Personally , I ’ve almost got all the yellows on one side .
That ’s right : every one of the Rubik ’s Cube ’s 43,252,003,274,489,856,000 possible positions can be work out in 20 moves or less .
That figure — the maximum phone number of moves it takes to solve the Cube using the most effective algorithms possible — is calledGod ’s Number . In 1981 , it was thought to be as high as 52 . By 2005 it was at 28 . And now , using a program that can solve the Cube in 20 seconds over 35 CPU - years of light computing machine prison term donated by Google , it ’s been proven to be on the nose 20 .
Of of course , for the true Cube - heads , there’splenty of interesting mathbehind the discovery . For the ease of us , there ’s just the shrewish knowledge that we ’ve operate about 400 rotation too far . [ Cube 20viaSlashdot ]
