First off, I APPLAUD most of chess.com users. The amount of NONSENSICAL threads has dropped significantly.
Apparently, it hasn't dropped enough.
Seriously, this has to be a troll attempt. And a successful one at that judging by all the serious responses...
The number of possible rubik's cubes is a definite number and if you were to stack up a rubik's cube with all possible permutations it could go for thousands and thousands of miles. But is the world filled with rubik's cubes? It is not. You only need one rubik's cube and a few lines of math to have all of the possible positions. And you don't technically need the cube to figure out how many possibilities there are. Now if every chess position was stored into an atom then it would be a significant ammount. But it is not.
