Can a piece of A4 paper be folded so that it's thick enough to reach the moon? While procrastinating around the web I stumbled on a page that contained  the image below, from cracked.com.
I can't help but believe that this is false… Even though the article header says: 

22 Statistics That Will Change The Way You See the World

My question: is what the image below implies a mathematical impossibility? (…Just for procrastination's sake…)


If you could fold a piece of A4 paper just 42 times it would be thick enough to reach the moon


The statement is true in two different senses.  As Sabyasachi shows, the intended sense that $2^{42}$ times the thickness of a sheet of paper is greater than the distance to the moon is correct.  In the spirit of achille hui's comment, the sentence is an implication with a false antecendent, so it is true in that sense as well.  It is also true to say "If you could fold a piece of A4 paper 42 times then the moon is made of green cheese."
