Basic science and astronomy knowledge can actually save your life. Let's say you were lost, all you'd have to do is find the North star to guide your way. Sure, there are millions of stars, so it makes it a little hard, but no one should die just because they can't point one out. Even better yet, that same astrological knowledge can prevent you from looking like a total idiot.
There's nothing spectacular about this picture to me, but this guy sure thought it was something special. His "new favorite picture" is a result of the serendipitous sun showing up at just the right time.... Or is it? If the sun is in his eyes, why is his shadow in front of him? BOOM. He's caught in the lie, but why? I could see if this picture made him look like Brad Pitt, but I think it would have been better off in the computer trash folder.
