Eli5: Why can you only fold a paper in half seven times, no matter the size ?
In: 4
As you fold paper its thickness increases exponentially. In other words every time you fold it, it gets twice as thick. After the 6th fold its the equivalent of having 64 pieces of paper stacked on top of each other. Folding it a 7th time results in a stack 128 which is just too much to reasonable fold.
