I was just out for a bike ride, during which an idle thought came to me about a rule of thumb that might deserve publicity. This rule of thumb is that the mention of wormholes in a popular science book, TV program, etc., indicates that real science is not what’s being discussed. When I got back to my office, I found that USA Today has a new story: String theorists suggest space wormholes possible. The source of the story is this preprint.
Via Twitter, the story’s author did get the obvious response to this claim: this isn’t news since everything is possible in string theory.
