Folding a piece of paper 42 times would reach the Moon
Each fold doubles the paper's thickness. Starting at 0.1mm, after 10 folds it's about 10cm thick, after 20 folds it's 100 metres, after 30 folds it's 107km (reaching the stratosphere), after 42 folds it's approximately 440,000km — the distance to the Moon. After 51 folds it would reach the Sun. The reason you can't actually fold paper more than 7-8 times is that the number of layers doubles each time, requiring exponentially more force. The theoretical calculation is perfectly sound.
Exponential growth is deeply unintuitive — the human brain tends to assume linear progression. That a mundane object like paper could theoretically touch the Moon through simple doubling seems like a mathematical trick, not a physical reality.
