Stephen Hawking just published a new solution to the black hole information paradox
Last year, British theoretical physicist Stephen Hawking hinted at research he and a couple of colleagues were working on that could solve the infamous black hole information paradox, which states that information about matter that gets destroyed by a black hole, according to Einstein’s general theory of relativity, is supposed to be fundamentally conserved, according to our understanding of quantum mechanics.
Now, that paper has finally been posted online, and as hinted by Hawking back in August, the solution to this paradox could be black hole ‘hairs’ that form on the event horizon, making a kind of two-dimensional holographic imprint of whatever’s been sucked in. He says the existence of these hairs is provable, and their existence could win him a Nobel Prize.
How to deal with a medical emergency on the Space Station
When Tim Peake blasted into orbit in December, he knew that the 40 hours of medical training he’d received would prepare him for most health problems during his six-month stay on the International Space Station.
In addition to life-saving skills, he had been taught how to stitch a wound, give an injection and even extract a tooth.
According to Nasa, this training would prepare him and his crew members for the most common medical problems faced on the ISS – like motion sickness, headaches, back pain, skin conditions, burns and dental emergencies.
NASA office to coordinate asteroid detection and hazard mitigation
NASA has formalised its ongoing program for detecting and tracking near-Earth objects (NEOs) as the Planetary Defense Coordination Office (PDCO). The office remains within NASA’s Planetary Science Division, in the agency’s Science Mission Directorate in Washington. The office will be responsible for supervision of all NASA-funded projects to find and characterise asteroids and comets that pass near Earth’s orbit around the Sun. It will also take a leading role in coordinating interagency and intergovernmental efforts in response to any potential impact threats.
More than 13,500 near-Earth objects of all sizes have been discovered to date — more than 95 percent of them since NASA-funded surveys began in 1998. About 1,500 NEOs are now detected each year.
