We're living in a Simulated Universe? Are you sure?

Pondering about the nature of the universe is always fun, isn't it? It's one of the cool things science fiction writers get to do.

So, this Oxford philosopher "proves," mathematically, that either you're living in a simulated universe, or else the world is going to end soon. Wow, that's bleak, no? Fortunately there are some flaws in his logic, leading to some even more fascinating ideas, which I've played with for fun in an article that was originally printed in the Bulletin of the Science Fiction and Fantasy Writers of America.

Enjoy it before the universe ends! :)
