Fold Paper to the Moon

Can Folding Paper Really Reach the Moon?

Yes, and that's the terrifying beauty of exponential growth. A sheet of paper is about 0.1 millimeters thick. Fold it once and it's 0.2mm. Every fold doubles the thickness, and doubling is a monster: 10 folds is thicker than your hand, 23 folds clears the Burj Khalifa, 30 folds passes the edge of space, and at fold 42 your paper stack stretches past the moon, 384,400 kilometers away.

Why Can't You Actually Do This?

Physics, rudely. Each fold halves the paper's length while doubling its thickness, and around 7 or 8 folds a normal sheet becomes too small and stiff to bend. The world record is 12 folds, set by Britney Gallivan in 2002 using a 1.2-kilometer roll of toilet paper and a formula she derived herself. In this game, though, your paper is infinitely foldable and the doubling never stops.

The Point of the Game

This is exponential growth made physical. The same math explains compound interest, viral spread, and why chess-board rice legends bankrupt kings. Nothing much seems to happen for the first 15 folds, and then suddenly you're passing Everest between two taps. That feeling of it sneaking up on you? That's exactly why humans are so bad at intuiting exponentials.
