The number of possible chess moves has been estimated to be even more than the number of atoms in the universe. The number of atoms in the universe is thought to be as many as 10^{81}, or 10 multiplied by itself 81 times, while the number of possible moves in chess is estimated to be 10^{120}. This calculation for chess movements is known as the Shannon number. The Shannon number includes illegal chess movements and is named after American mathematician Claude Shannon, who calculated this estimation in 1950.

There are 43,768 moves for white and black. Not all are possible at all times; there are only 20 possible moves at first. The combinations of moves would take "forever" to count - any count is a gross estimation. |

Ten to the Eighty-first Power = 8,100 Ten to the One hundred twentieth power = 12,000. These are not brobdignagian numbers, as one might use in quantification of all matter in the universe. Can anyone elaborate? |
