Question 1 of 5
What is the estimated number of atoms in the observable universe?
Chess may look like a simple game of 64 squares and 32 pieces, but the mathematical complexity is staggering. The number of possible unique chess games (the Shannon Number) is estimated at 10^120 — that's a 1 followed by 120 zeros. For comparison, there are only an estimated 10^80 atoms in the entire observable universe.
This is why computers took so long to master chess, and why human grandmasters can play for decades without exhausting new possibilities. Every game you play has almost certainly never existed before in exactly that form.
