Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.

Being a geek is all about your own personal level of enthusiasm, not how your level of enthusiasm measures up to others. If you like something so much that a casual mention of it makes your whole being light up like a halogen lamp, if hearing a stranger fondly mention your favorite book or game is instant grounds for friendship, if you have ever found yourself bouncing out of your chair because something you learned blew your mind so hard that you physically could not contain yourself — you are a geek.

And as someone who writes about movies, and who cares about the big, flawed thing we call fandom, I’m saddened by someone turning that shared enthusiasm into a weapon. And even if this tragedy hadn’t happened at the premiere of one of a dwindling number of genuinely mass cultural events, I hate the idea of using an audience’s suspension of disbelief, their openness to and absorption in the spectacle unfolding before them, as cover—the gunman reportedly started shooting during a sequence involving gunfire, meaning the audience was slower to react. We are vulnerable when we go to the movies, open to fear, and love, and disgust, and rapture, surrendering our brains and hearts to someone else’s vision of the world. We don’t expect to surrender our bodies, too.
