Ad copy - "Nights you'll remember for light years."
(ad includes outer space characters)
Seriously? A billion dollar corporation can't hire someone to check on these things? Even fucking Wikipedia knows that a light year is a measure of distance. Even better than the sometimes dubious (but always loved) Wikipedia is Phil Plait's Bad Astronomy page on light years.
And while we're here, be sure to visit his site for loads of awesome shit regarding astronomy (includes movie breakdowns!). Even if you're not an armchair astrophysicist* like me there's still tons of good stuff to be found on Bad Astronomy!
*didja even know these existed? armchair quarterbacks yes but astrophysicists? I know! I'm so geeked out for science!
ETA: Turns out the BA blog has a nice video up today. The camera work is terrible (and I think I hear a baby crying in the background) but the message is solid. I'll embed it below so hat tip BA blog.
