Light-year
From Slackerpedia Galactica
(Redirected from Light Year)
Dude, that's a long time... oops, I mean, distance.
Turns out, it's the distance light travels through a vacuum in one year- about 6 trillion miles, 9.5 trillion kilometers, 90,000 AUs or 0.3 parsecs. I understand, I don't really know what any of those numbers mean either. Let's just agree that it's a really long way, and it's handy because it allows us to convert 17,952,134,005,919 miles to "about 3 light-years (ly)".
Related terms like light-second, light-hours, light-houses, etc, have similar defintions.
Also, a light-year is just like a regular year, only with fewer calories.
Wikipedia seems to think different.
