# Cards shuffle

If you correctly shuffle a deck of cards, you'll create a configuration that has never existed, and likely never will again. This is because there are 8.1x10^67 possible arrangements for fifty-two cards, and getting through each of them would take longer than the lifespan of the universe. It also turns out that the above statistics are a little bit scarier than many people realize. According to the mathematics of the situation, as many as 91.5% of Solitaire games should be winnable... and yet, in spite of this, people who have actually played the game report that only 8% of games result in a win. Given that shuffling a deck of cards almost always results in a new configuration, and given that approximately 90% of those configurations should result in a winning game of Solitaire, we're forced to conclude that somehow, we're seeing less than 5% of the available configurations for a deck of cards. By a strange coincidence, it turns out that less than 5% of the universe comprises normal matter and energy. The rest of it is dark matter and dark energy. What does this mean? It means that when you shuffle a deck of cards, you're only going to wind up with observable configurations. 95% of that 8.1x10^67 can be classified as "dark configurations." However, mathematically speaking, the more you shuffle a deck of cards, the more likely it is that you'll stumble on one of those "dark configurations." In other words, it's only a matter of time before someone answers some major astrophysics questions using only a deck of cards.
