If you could fold the paper 42 times, it would have reached the moon

It sounds strange, but the way it is. Let proizvedёm calculations: Moon from Earth of about 384 000 km. The thickness of the piece of paper - 0, 01 cm. So, if you add pages to each other, we need 3 840 000 000 000 000 pages to stack grown to the moon.

But if you fold the paper in half, and then another half, and then more, then it comes in exponential growth. For any exponentially growing quantities greater than the value it receives, the more rapidly growing. 1 again folded page will have a thickness of 2 times as large as the original. Folded 3 times - 8 times the original. If we could put down the page 20 times, it would exceed the Everest. Folded 42 times - reached the moon. A 94-fold would give us something about the size of the visible universe.

The only problem is that the paper sheet of any size can not be folded more than 7 times.
