Jedidiah Becker for redOrbit.com — Your Universe Online Over the years, the British cosmologist and theoretical physicist extraordinaire Stephen Hawking has become as well known for his ability to translate mind-boggling research about the universe into language that´s accessible to the layman as he is for his groundbreaking theoretical work in gravitational singularities and black hole radiation. This month, Cambridge´s wheelchair-bound conqueror of the cosmos turns 71....

A team of UBC physicists and engineers have designed an experiment featuring a trough of flowing water to help bolster a 35-year-old theory proposed by eminent physicist Stephen Hawking. In 1974, Hawking predicted that black holes--often thought of having gravitational pulls so strong that nothing escapes from them--emit a very weak level of radiation. According to the theory, pairs of photons are torn apart by a black hole's gravitational field--one photon falls into the black hole, but the...

Physicists at Penn State have provided a mechanism by which information can be recovered from black holes, those regions of space where gravity is so strong that, according to Einstein's theory of general relativity, not even light can escape. The team's findings pave the way toward ending a decades-long debate sparked by renowned physicist Steven Hawking. The team's work will be published in the 20 May 2008 issue of the journal Physical Review Letters.In the 1970s, Hawking showed that black...

Professor Sam Braunstein, of the University of York's Department of Computer Science, and Dr Arun Pati, of the Institute of Physics, Sainik School, Bhubaneswar, India, have established that quantum information cannot be "Ëœhidden' in conventional ways, or in Braunstein's words, "quantum information can run but it can't hide." This result gives a surprising new twist to one of the great mysteries about black holes. Conventional (classical) information can vanish in two ways, either...
