ahhhhh universe!
It is temendously large. While the outer limits have not been measured, it is estimated to be as much as 20 billion light years in diameter (at speed of 186 miles per second). there are an estimate one billion galaxies in the universe and an estimate 25 sextillion stars. The Milky Way in which we live contains over 100 billion stars and is so large that even traveling at speed of light would require 100,000 years to cross its diameter. Light travels in one year approximately 5.87 x 10,000,000,000,000 miles; in 100,000 years that would be 5.87 x 1,000,000,000,000,000,000 miles or 587 guadrillion miles to get across the diameter of a single galaxy. If we drew a map of the Milky Way galaxy, and represented the earth and sun as two dots one inch apart (thus a scale of one inch equals 93 million miles, the distance between sun and earth), we would need a map at least four miles wide to locate the next nearest star, and map 25,000 miles wide to reach the center of our galaxy. without doubt this is a rather impressive universe!
