Grab a piece of paper and fold it in half, it is now twice as thick as it was before. So what happens if you repeat the process? It is now four times as thick as the original piece. Just keep on folding and imagine how thick it would be after 100 folds. Reasonably thick you'd think, and you'd be correct.

At seventeen folds it would be taller than your average house. Three more folds and that sheet of paper is a quarter way up the Sears tower. Ten more folds and it has crossed the outer limits of the atmosphere. Another twenty and it has reached the sun from the earth. At sixty folds it has the diameter of the solar system. At 100 folds it has the radius of the universe.

It seems incredible but it is true, click here to see the table.
