Report on this has been circulating the news wire for a few days ever since the silly editors at New Scientists proclaimed that it can happen (shall I mention for the gazillion'th time why I consider New Scientist as the science's supermarket tabloid?). I suppose when colliders like RHIC didn't actually produce blackholes, some people need to come up with other more creative ways to get them free publicity. So why not a wormhole?
We finally have a sensible article that discusses this. Still, the crackpots of the world are already rejoicing and jumping all over this.
