@justin_danger_nunley: If you could fold a standard piece of paper (about 0.1 mm thick) in half 42 times, the stack would reach about 440,000 kilometers, which is past the average 384,400 km distance to the Moon. Why The Math Works Exponential growth: Each fold doubles the thickness of the paper. Double trouble: 10 folds: About the size of a note pad (10 cm).20 folds: Over 100 meters high (taller than a big building). 30 folds: Reaches 100 kilometers high (into space). 42 folds: Reaches the Moon. Why It Is Physically Impossible The physical limit: You cannot actually do this in real life.Too thick to bend: The paper gets too hard to fold after 7 or 8 tries. World record: The highest number of times anyone has folded a single piece of paper in half is 12 times (achieved using a very long sheet of thin toilet paper).
