subreddits related to r/astrophysics
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.
Engineers apply the knowledge of math & science to build maintainable systems designed to solve problems. AskEngineers is a forum for questions about the processes and standards used to build these systems, as well as for questions about the engineering profession and its many disciplines.
