The aim of /r/Physics is to build a subreddit frequented by physicists, scientists, and those with a passion for physics. Papers from physics journals (free or otherwise) are encouraged. Posts should be pertinent, meme-free, and generate a discussion about physics. Please report trolls and intentionally misleading comments.
**A place to discuss published SF**—novels, short stories, comics, images, and more. Not sure if a book is SF? Then post it! Science Fiction, Fantasy, Alt. History, Postmodern Lit., and more are all welcome here. **The key is that it be speculative, not that it fit some arbitrary genre guidelines**. Any sort of link or text post is welcome as long as it is about printed / text / static SF material.
This reddit is for fans and creators of Science Fiction and related media in any form. SF topics should involve plausible ideas reached through the rational application of science. General speculative fiction posts are fine as long as they involve Science Fiction.
