I suck at Rubik's Cube. Nevertheless, I can solve any possible combination in 20 moves or less.
Yep, that's right.
Well, OK, I can in theory.
Some people over in California did a science and proved that the lowest number of moves in which all possible Rubik's Cube combinations can be solved - the so-called 'God number' - is 20. This loosely means that God is no better than me at Rubik's Cube. He is restricted by the same limitations. Nice to know.
The guys over at Premier are having a wee debate on the implications of this (that God cannot solve all combinations in less moves) if you want to have a look see...
Alternatively...there is always this method:
