This write-up is as old as job with a few additions by Moses.
Typos are no extra charge.
Imagine that the sun were the size of a softball. If you began unrolling a roll of toilet paper next to the softball-sized sun, you would have to unroll 36 sheets before you came to Mercury, the first planet in the solar system. Mercury would be the size of a hole made by a thin staple. Had you started out at the sun and traveled at the speed of light, it would take three minutes to reach Mercury. Continue unrolling toilet paper until you reach 57 sheets.
