The answer is simple: The exponential growth.
The thickness of the middle of the sheet of paper is 1/10 of a millimeter.
If you fold it in half, doubling its thickness.
The third folding will give you a human nail thickness.
Seven folding - and you get a thick notebook of 128 pages.
10 - and the thickness of the paper will be about the width of the palm.
23rd you will receive a paper stack height of a kilometer.
30 folding will take you into space. At this time your piece will have a height of 100 kilometers.
Continue to fold. 42 fold will bring you to the moon. 51 - and you will find yourself in the sun.
Now quickly scroll to the 81-th folding and get a stack of paper as thick as 127,786 light-years - is almost equal to the diameter of the Andromeda Galaxy (which is about 141,000 light-years).
90 folding will give 130.8 million light-years - is more than a supercluster of the Virgin, which has a diameter of about 110 million years. Virgo supercluster contains the local galactic group, which consists of the Andromeda Galaxy, our own Milky Way, and about a hundred other galaxies.
Finally, at 103 folding you go beyond the observable universe, the diameter of which according to rough estimates of 93 billion light-years
