*It is possible to cut of one of the hairs on your head and make it as long as it's width by cutting it. If you did that, then the hair that is as long as it's width would be 500 novemvigintillion times smaller than the observable universe.1.3 Sizes of the -illions - Pointless Large Number Stuff#One trigintillion
