Why does paper tear easily when folded?
When you fold a piece of paper hard enough there is a permanent elongation along the line of fold. So now this region has a lesser yield point ( i.e. can take lesser amount of stress). It thus forms the line of least resistance and the paper is torn along that line.

What would happen if you folded a paper 100 times?
With just over 100 folds, the thickness of the paper would be equal to 93 billion light-years. The reason for this is exponential growth. When you perfectly fold the paper in half, you will double its thickness. Folding the paper in half a third time will get you about the thickness of a nail.

What happens when you fold a paper 42 times?
Given a paper large enough—and enough energy—you can fold it as many times as you want . Problem: If you fold it 103 times (only if you could ) , the thickness of your paper will be larger than the observable Universe: 93 billion light-years. Yes,on folding the paper 42 times ,it would reach the moon.
