Quantum black hole study opens bridge to another universe
Physicists have long thought that the singularities associated with gravity (like the inside of a black hole) should vanish in a quantum theory of gravity. It now appears that this may indeed be the case. Researchers in Uruguay and Louisiana have just published a description of a quantum black hole using loop quantum gravity in which the predictions of physics-ending singularities vanish, and are replaced by bridges to another universe.Singularities, such as the infinitely strong crushing forces at the center of a black hole, in a physical theory are bad. What they tell you is that your description of the universe fails miserably to explain what happens as you approach the singularity. Tricks can sometimes resolve what appears to be singular behavior, but essential singularities are signs of a failure of the physical description itself.

The Raspberry Pi, which was launched last year, was originally made in China to help keep costs down, but in September 2012 the Foundation started moving manufacture to a plant owned by Sony in South Wales. Today, the Pencoed factory has made its millionth British Raspberry Pi, which together with the existing Chinese units adds up to 1.75 million Raspberry Pis worldwide. Raspberry Pi founder Eben Upton told the BBC that the device has already surpassed the sales of the BBC Micro, proving that there is “a latent need for something like this”.
