Friday's Fact

There is one particular area of study that is a part of all others, what is it? It is the base for everything else. I mean consider physics, chemistry, math, biology, medicine, astronomy, psychology, or whatever you can dream up and you will find this as the root. Can you name it?

Last weeks fact is “about 13 billion light years thick.” It was very closely approximated by pogofrog, who within minutes of my posting made a rough guess of ten thousand million light years. Good Job. Loy said, “It is impossible to fold a piece of paper over itself more than seven times.” Literally correct but assuming you can then:

After 6 folds and compressing it as best I could I measured approximately ¼ of an inch thick. Continuing using that measurement you get 7 folds at ½ inch, 8 folds is 1 inch etc.

14 folds is about 5.3 feet thick.

24 folds is about 1 mile thick.

51 folds is about equal the distance to the sun. (from earth)

66 folds is about one light year thick.

73 folds is about as thick as light would travel in a long lifetime. (99 years)

100 folds is about 13.3 billion light years….thick.

Amazing…don’t you think?
