Hawking offers new solution to ‘black hole information paradox’

Addressing a current controversy in physics about information in black holes, “I propose that the information is stored not in the interior of the black hole as one might expect, but on its boundary, the event horizon.”

The event horizon is a boundary around a black hole beyond which events cannot affect an outside observer, also known as “the point of no return” — where gravitational pull becomes so great as to make escape impossible.

Hawking is now suggesting that the information about any incoming particles passing through this event horizon is translated into a 2D hologram. “The idea is the super-translations are a hologram of the ingoing particles,” he said. “Thus they contain all the information that would otherwise be lost.”

New imagery of NASA’s asteroid mission released

This concept image shows an astronaut preparing to take samples from the captured asteroid after it has been relocated to a stable orbit in the Earth-moon system. Hundreds of rings are affixed to the asteroid capture bag, helping the astronaut carefully navigate the surface.

NASA spacecraft reactivated to hunt for asteroids

This artist’s concept shows the Wide-field Infrared Survey Explorer, or WISE spacecraft, in its orbit around Earth. In September of 2013, engineers will attempt to bring the mission out of hibernation to hunt for more asteroids and comets in a project called NEOWISE. (Credit: NASA/JPL-Caltech) NASA will revive the Wide-field Infrared Survey Explorer (WISE) next month with the goal of […]

Is faster-than-light travel possible?

Alcubierre warp drive (credit: Anderson Institute) Engineers at NASA Johnson Space Center are designing instruments to find out, by slightly warping the trajectory of a photon and measuring the distance it travels, The New York Times reports. Inspiration for the research came from Mexican physicist Miguel Alcubierre, who proposed in 1994 a method of stretching space in […]

Detecting DNA in space

Gene-sequencing chip can survive space radiation on Mars, MIT scientist finds Is there DNA on Mars? (credit: NASA) If there is life on Mars, it’s not too farfetched to believe that such Martian species may share genetic roots with life on Earth, based on RNA or DNA. That’s because more than 3.5 billion years ago, […]

Robot ape to colonize the Moon?

iStruct Demonstrator, space robot (credit: DFKI) The German Research Center for Artificial Intelligence (DFKI) and the University of Bremen are working on an ape-like robot called the iStruct Demonstrator that they classify as a “Space Robot.” Lately the mechanical monkey has been practicing how to walk and balance in the center’s mock lunar landscape, Gizmag reports. An ape-like body […]

Revolutionary space engine turns an airplane into a spaceplane

How Skylon will look as it takes off bound for Earth orbit (credit: Reaction Engines) A revolutionary engine that can turn an aircraft into an orbiting spaceplane has won fresh backing from the British Government. The hybrid engine called Skylon (Synergistic Air-Breathing Rocket Engine) — is currently being developed by Reaction Engines, SEN reports. Until now, spacecraft heading […]

UltraRope could make kilometer-high elevators possible

(Credit: Kone) With a new lightweight material known as UltraRope, however, elevators should now be able to travel up to one kilometer (3,281 ft) continuously, Gizmag reports. Using traditional steel lifting cables, they can’t go farther than 500 meters (1,640 ft) in one vertical run. UltraRope from Finnish elevator manufacturer Kone, unveiled this Monday in London, is ribbon- or […]
