Getting a glimpse of the big picture.
I've been going to the Hubble Space Telescope Advent Calender 2008 every day this month. And let me tell you-- petty problems melt.
BTW, for those of y'all who don't think about these things a lot, a light year is the distance that light travels in a year.
The speed of light is c, which is 186,000 miles per second.
That's about 5,869,713,600,000 miles. Getting on toward six trillion miles, for just one light year of distance. Makes our little 8.5 light-minute A.U. of 93 million miles seem pretty insignificant, doesn't it?
