Oh come on ... the right question is http://www.wolframalpha.com/input/?i=ceil%28log2+%28+%28dist... , to which the answer is of course: 42

...in other words: fold a paper 42 times and you reach the moon.

but you can't fold a paper more than 8 times

And only 8 more folds to reach the sun!

Ain't exponentiality awesome?

And only 41.46 more folds to reach the size of the observable universe! :)

... requiring about 4 trillion sheets:

... or 2.586 trillion square feet of paper:

This makes me wish wolfram alpha were social. I'd love to be able to have a conversation about interesting formula and results.

That's a great idea. You can share interesting results with @WolframFunFacts.

What is the meaning of life, the universe, and everything...?
