light

a comment on digg:

"had to look it up, but light travels about 186,282 miles per second (yeah outrun that). There are 31,536,000 seconds in a 365 day year. If you multiply that together you get about 5,874,589,152,000 miles light would travel per year in a straight line! (a light year)

Now if you REALLY wanna get into it, multiply 5,874,589,152,000 miles a year by 230,000,000 (light years away) and you have the distance to that image: 1,351,155,504,960,000,000,000 miles away"
