Into the science fiction event horizon

James Wallace Harris has been on a roll lately with his blog. Following up on his recent Science Fiction Short Stories State of the Union, he now offers the fascinating Science Fiction Event Horizon. Just as the event horizon of a black hole traps everything which enters it, Harris states that believing in certain science fiction cliches can trap a believer in a genre-created event horizon. To quote Harris:

"What we know about physics and astronomy puts nearly all speculative fiction about space travel inside the SF Event Horizon. If you are a true believer in Star Wars, then you are trapped inside and can’t see out. Is it any wonder that the generation after the Star Wars generation embraced Tolkien mythology and Harry Potter?

"Science fiction as true speculative fiction is going through a morbid period right now. Has science thrown most of science fiction or speculative fiction into the gravity well of fantasy?"
