Folding a Piece of Paper More than Seven Times
If you could somehow fold a piece of paper in half 103 times, the paper would be as thick as the observable universe.
Such is the power (*cough*) of exponential growth, but of course you’d never get anywhere close to that many folds. The theoretical limit for folding paper was long thought to be seven or eight folds. You can see why watching this hydraulic press attempt the 7th fold…the paper basically turns to dust.
But in 2002, high school student Britney Gallivan proved that you could fold a piece of paper 12 times. Here’s Gallivan explaining the math involved and where the limits come in when folding:
