Just a quote from one of my favourite episodes of Star Trek, 'Is There in Truth No Beauty?' from 1968... So poetic and beautiful. Sometimes, the quality of the dialogues are just beyond belief on this show.

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.
