Through a series of unfortunate events last weekend, I was forced to sit through a viewing of Twilight. In all honesty, it isn't that horrible of a movie. But what I found most entertaining was the abilities of the blood suckers. You can't really critique the physics of vampires, because who can say that their insane abilities wouldn't be made possible by magic or sparkles or something? But either way, I still have questions. In the movie there's a scene where the characters play vampire baseball during a storm, as they need the thunder to camouflage the sounds of them playing. So my question is: how hard would a baseball really need to be hit to create a noise as loud as thunder?
I found that your average clap of thunder registers at about 120 decibels. Some of the loudest cracks of a bat will only come to about 30 decibels. To create that sound, a batter exerts about a 35,000 N force on the bat. Just with that information, one can imagine what an incredible amount of force the characters must be capable of to create such a loud sound with the bat and by running into each other. It sounds like a baseball game I'd actually like to attend, although it'd be impossible for a wooden baseball bat to withstand that kind of force without splintering, regardless of the legitimacy of super strong vampires.
