It's terrifying that people take edge-of-model science, like tachyons and then turn them into weird mystical pseudoscience (which I hate). Tachyon Healing and the Physics of Love has a title like an Upsideclown article, and says that these superluminal particles give you superpowers. Relatively tame, compared to the insiduous nature of Tachyon Field Theory which starts off in solid physics then collapses into unsupported declarations of biologic energy and so on and so forth.
