A trillion seconds is equal to 31,700 years.
A trillion inches is equal to 15,800,000 miles.
In other words, a trillion seconds ago, Stone Age man lived in caves, and mastodons roamed Europe and North America.
Or, a trillion-inch journey will carry you 600 times around the Earth, and leave more than enough distance to carry you to the moon and back.

Isaac Asimov is curious about nearly everything, and he has made it his business to share whatever he learns with us-there are few people as good at it as he is.
