There are quite a few that are out there both in literary sources as well as in real life.
Without diving into a shouting match between proponents I'll give a few popular fictional pseudosciences:- Temporal Mechanics (Time Travel)
- Warp Engineering (Popular Faster-Then-Light Travel)
- Psychic Engineering (Building Mental Constructs such as Telepathic Blocks)
- Planetologist (Keynes from Dune, involves terraforming whole planets and establishing new ecosystems on planets.)
- Robotologist (Building artificial life forms and Artifical Intelligence)
- Xeno\Exo biologist (Study alien (off world) life forms)
- Solar Engineer (Omega from Doctor Who was a Solar Engineer)
From the real world for a few, non-inflammitory sciences that came and went:- Phernology (Studying bumps on the head)
- Eugenics (The science of breeding superior humans. Dangerously close to making a comback with gene therapy.)
- Freudian Psycology (where everything seemed to involve sex at some point. Absorbed into modern psychology).
- Greek Alchemy (Fire, Earth, Air, and Water made up the universe.)
