First Acoustic Black Hole Created 165

Posted by Soulskill from the for-music-that-really-sucks dept.
KentuckyFC writes "One of the many curious properties of Bose Einstein Condensates (BECs) is that the flow of sound through them is governed by the same equations that describe how light is bent by a gravitational field. Now, a group of Israeli physicists have exploited this idea to create an acoustic black hole in a BEC. The team created a supersonic flow of atoms within the BEC, a flow that prevents any phonon caught in it from making headway. The region where the flow changes from subsonic to supersonic is an event horizon, because any phonon unlucky enough to stray into the supersonic region can never escape. The real prize is not the acoustic black hole itself but what it makes possible: the first observation of Hawking radiation. Quantum mechanics predicts that pairs of phonons with opposite momentum ought to be constantly springing in and out of existence in a BEC. Were one of the pair to stray across the event horizon into the supersonic region, it could never escape. However, the other would be free to go on its way. This stream of phononic radiation away from an acoustic black hole would be the first observation of Hawking radiation. The team hasn't gotten that far yet, but it can't be long now before either they or their numerous competitors make this leap."

The Sims 3 Racks Up Over 180,000 Downloads Prior To Release 187

Posted by Soulskill from the big-spenders dept.
Bloomberg reports that pirated versions of EA's The Sims 3 were downloaded over 180,000 times between May 18 and May 21. The game will not be officially released until June 2nd, and it does not make use of SecuROM for DRM. Quoting: "That outpaces the 400,000 downloads over three weeks for Electronic Arts' Spore, the most-pirated game of 2008. ... Copies of the game available on file-sharing Web sites aren't the full version, Electronic Arts said. 'The pirated version is a buggy, pre-final build of the game,' Holly Rockwood, a company spokeswoman, said in an e-mailed statement. 'It's not the full game. Half the world — an entire city — is missing from the pirated copy.'"

Judge In Pirate Bay Trial Biased 415

Posted by CmdrTaco from the aren't-we-all dept.
maglo writes "The judge who handed down the harsh sentence to the four accused in the The Pirate Bay trial was biased, writes Sveriges Radio (Sweden Public Radio): sr.se (swedish). Google translation. The judge is member of two copyright lobby organizations, something he shares with several of the prosecutor attorneys (Monique Wadsted, Henrik Pontén and Peter Danowsky). The organizations in question are Svenska Föreningen för Upphovsrätt (SFU) and Svenska föreningen för industriellt rättsskydd (SFIR)."
