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 subreddit to draw simple physics questions away from /r/physics. No real rules; ask away. If your basic physics question isn't answered in a day, you can post it to /r/physics if you mention that you didn't get an answer on /r/AskPhysics (unless it's a homework-related physics question).
Science Fiction, or Speculative Fiction if you prefer. Fantasy too. Asimov, Bradbury, Clarke, Dick, Heinlein and other SF books. SF movies and TV shows. Fantasy stuff like Tolkien and Game of Thrones. Laser guns, space ships, and time travel. etc. Star Trek, Battlestar, Star Wars, etc.
A subreddit for really great, insightful articles and discussion. Please follow reddiquette, and READ THE ARTICLE before voting or discussing. Downvotes should only be used if something doesn’t contribute to intelligent discussion, not just because you disagree. Please use the report button if you see something that doesn’t belong.
/r/EverythingScience is the sister subreddit to /r/science. With a broader rule set than /r/science, it is the place for high quality scientific content that doesn't necessarily reference a peer-reviewed paper from the last 6 months.
A very active subreddit to debate and pose arguments to atheists, people who lack a belief in any of the gods that other people have proposed exist. Post your best arguments for the supernatural, discuss why your faith is true, and tell us how your reasoning led you to a belief in the supernatural. r/DebateAnAtheist is dedicated to discovering what is true and real and useful and using debate to ascertain beliefs we can be confident about. Remember to upvote comments with solid effort.
