Colliding Particles Can Make Black Holes After All 269

cremeglace writes with this excerpt from ScienceNOW: "You've heard the controversy. Particle physicists predict the world's new highest-energy atom smasher, the Large Hadron Collider (LHC) near Geneva, Switzerland, might create tiny black holes, which they say would be a fantastic discovery. Some doomsayers fear those black holes might gobble up the Earth — physicists say that's impossible — and have petitioned the United Nations to stop the $5.5 billion LHC. Curiously, though, nobody had ever shown that the prevailing theory of gravity, Einstein's theory of general relativity, actually predicts that a black hole can be made this way. Now a computer model shows conclusively for the first time that a particle collision really can make a black hole." That said, they estimate the required energy for creating a black hole this way to be roughly "a quintillion times higher than the LHC's maximum"; though if one of the theories requiring compact extra dimensions is true, the energy could be lower.

PlayStation Network Expanding To Involve Other Devices 63

At CES, Sony's Kaz Hirai confirmed that the company will build out its PlayStation Network for use with other devices, such as televisions, Blu-ray players, and PCs. Quoting: "... the expansion starts next month with the availability of the PSN video store on these other devices, and Hirai explained they are constructing a mechanism to create a single user ID across the entire network (if you have a PSN account, it's good to go on any other applicable Sony device, and if you create one on another device, it'll work on PSN). And finally, Hirai also announced the formation of a new Sony division — called Sony Network Entertainment, Inc. — to drive this expansion of the PSN service into a Sony-wide network."
