**The myth**: You can't fold a paper in half more than eight times.*

**The reality**: Given a paper large enough—and enough energy—you can fold it as many times as you want.

**The problem**: If you fold it 103 times, the thickness of your paper will be larger than the observable Universe: 93 billion light-years. Seriously.

**The answer is simple**: Exponential growth. The average paper thickness in 1/10th of a millimeter (0.0039 inches.) If you perfectly fold the paper in half, you will double its thickness. **Things get interesting quickly**.

**Folding the paper** in half a third time will get you about the thickness of a nail. Seven folds will be about the thickness of a notebook of 128 pages.
