At first the title of this post might seem ridiculous but its true. If it was possible to fold a sheet of paper 42 times it would be thick enough to reach the moon. Here is the explanation Each time you fold a paper it doubles in thickness. Zero folds=1 sheets tick, one fold=2 sheets thick, two folds=4 sheets thick. This follows the rule where the thickness (in sheets) is equal to two raised to the number of folds or t(sheets)=2#folds To convert from number of sheets thick to a dimension we just multiply by the thickness of one sheet (varies by type but .1mm is a good average). Where .1mm is 10-4 meters. So thickness in meters is given by the equation T(m)=(10-4)*2#folds So if we want the thickness to be the distance to the moon (3.939*108 meters) we plug that into the equation and solve for # of folds 3.939*108=(10-4)*2#folds 3.939*1012=2#folds ... read more
