well, the universe is 45 billion light years in all directions and the earth measures 24,000 miles around.


A light year is 5,878,499,810,000 miles. Now multiply that by 45 billion which equals about 270,000,000,000,000,000,000,000. I doubt there is even a word for that number. Put 24,000 over that number and you will have a reasonable answer, in theory only of course.
