Myth: No sheet of paper can be folded in half more than 8 times. (On the in fact, the current record is already 12 times, it belongs Britney Gallivan). Reality: If You Will Be Big Enough a piece of paper – and enough energy to fold it – you can fold it as many times as you like. However, there is one problem: If you fold it 103 times, the thickness of the stack of paper will exceed the dimensions of the known universe – 93 billion light years. Seriously.

But how can a tenth of a millimeter thick sheet become more than the universe?
The answer is simple: exponential growth. Middle sheet thickness paper is 1/10 millimeter. If you fold it perfectly in half, its thickness will double. But then things become really interesting.
A third folding will give you the thickness of a human nail.
Seven folds – and you get a notebook thickness of 128 pages.
10 – and the thickness of the paper will be approximately the width of the palm.
23 – and you get a stack of paper a kilometer high.
30 foldings will take you into space. At this point, your leaflet will have a height of 100 kilometers.
Keep folding. 42 folding will bring you to the moon. 51 – and you will find yourself in the sun.
Now quickly scroll to the 81st folding and get a stack paper with a thickness of 127.786 light years – this is almost equal the diameter of the Andromeda Nebula (which is approximately 141,000 light years).
90 folds will give 130.8 million light years – that’s more than Virgo Supercluster, which has a diameter of approximately 110 million years. The Virgo supercluster contains a local galactic a group that includes the Andromeda Nebula, our own The Milky Way, and about a hundred other galaxies.
And finally, at 103 folding, you go beyond the observed The universe, whose diameter is estimated to be 93 billion light years.
The math is amazing, friends. Just like ours Universe.
