Can it possible a piece of paper reach the moon?
Well, the answer may surprise you. You would need to fold the
piece of paper 42 times for it to be thick enough to reach
the moon.
Reality:
It is impractical to get a long enough piece of paper to fold
it 42 times. Paper will not exceed its maximum dimension in
its unfolded state, clearly a good theory would not allow for
unbounded streching of paper, when the paper is simply
folded.
The correct mathematics of paper folding includes a term for
the initial length of the paper and how it folds. So a piece
of paper reaching the earth must be at least as long as that
distance before folding.
So you can, in theory , fold a long 1mm thick sheet of paper
in half 42 times to reach the moon by thickness, but the
length of the sheet to begin is with is: L = 1.012*10^21 m.
That's just under 107,000 light years. And our galaxy is
about 100,000 light years across.
Fact:
The current world paper-folding record belong to
California high school student Britney Gallivan, who in 2002
managed to fold a 1.2km-long piece of tissue paper 12 times.
