Chess VS universe.
Have you ever heard of the number novemtrigintillion? Most likely not. It's a one followed by one hundred and twenty zeros. And it is this number (also called the Shannon number) that reflects the number of possible moves in a chess game.
In 1950, the American engineer, cryptanalyst and mathematician Claude Shannon calculated that the number of possible variations (complete sequences of moves) in a chess game is estimated at about 10¹²⁰.
This is such a large value that it exceeds many times not only the number of stars in the observable universe, but also the number of atoms in this universe, which is estimated at about 10⁸⁰.
Chess to you, great cosmos!
