Science shows make the most ridiculous comparisons. Imagine if we all talked like that: "I walked 11 football fields to work today because I missed the subway by the width of a human hair."
Having said that they do come up with the coolest stuff - like this:
If you cut a piece of paper in two, pile the two halves, then cut the pile in two and stack those together... and repeat that 100 times, how tall would the stack be?
More than 13 billion light years tall - about as far as the most distant galaxy we have seen.
Proof: Two to the 100th Power
Nerd awesomeness FTW.
