Paper folding math

I hesitate to even ask this due to the source (quora), but they claim that: “2. If you could fold a piece of paper in half on itself 100 times, the height of the resulting folded paper would not fit within the current known universe.” That seems incredible. Is it even remotely true? Link: https://www.quora.com/?digest_story=1287380

Folding paper in half

I was always lead to believe that it was impossible to fold paper in half more than 7 times but a friend of mine maintains that some girl has managed to fold it 12 times. I can’t find anything about this, anyone any knowledge?

Or maybe this column by Cecil.

Can a piece of paper be folded in half no more than seven times?
