Bad Astronomy is a really amusing site that talks about all of the bad astronomy that can be found on TV, in movies, on the news, and so on. It seems like they could dedicate a whole site to bad astronomy in just Star Trek... And thanks to the Astronomy class I'm currently taking, I appreciate this all the more.
Next, we need a badmedicine.com or something to cover ER and also Star Trek. Or maybe there should just be a badstartrekscience.com. Wait, who am I kidding? No one in their right mind would tackle a project that gigantic.
