Last year August, Stephen Hawking announced he had been working with Malcom Perry and Andrew Strominger on a solution to the black hole information loss problem, and they were closing in on a solution. But little was explained other than that this solution rests on a symmetry group by name of supertranslations.
Interstellar is one of the best sci-fi movies of the last decade, imagining a post-apocalyptic human population that needs to be saved from a dying Earth. A nearby black hole has the answers to humanity’s problems, and the brilliant script tells us we can enter a black hole and then use it to transcend space and time. In the film, the black hole also leaks out information that can save us, and it is captured by a complex computer as it’s being entered. That might seem implausible, but since we don’t know a lot about how black holes work, we can certainly accept such an outlandish proposition in the context of the movie.
In real life, however, physicists are trying to figure out how to access the secrets of a black hole. And it looks like some researchers have a theory to retrieve information from it, though it’s not quite as exciting as the complex bookcase that Interstellar proposes.

Interesting, but older…
Two separate research groups, one of which is from MIT, have presented evidence that wormholes — tunnels that may allow us to travel through time and space — are “powered” by quantum entanglement. Furthermore, one of the research groups also postulates the reverse — that quantum entangled particles are connected by miniature wormholes.
A wormhole, or Einstein-Rosen bridge to give its formal name, is a hypothetical feature of spacetime that exists in four dimensions, and somehow connects to another wormhole that’s located elsewhere in both space and time. The theory, essentially, is that a wormhole is a tunnel that isn’t restricted by the normal limitations of 3D Cartesian space and the speed of light, allowing you to travel from one point in space and time, to another point in space and time — theoretically allowing you to traverse huge portions of the universe, and travel in time.

Physicists think they’ve come up with a way to learn a bit about the interior of a black hole — an impossible procedure that shows the insanity of studying the heart of a singularity.
Is it possible that our universe is but one of many, with laws that mean nothing in the “pocket universes” that co-exist all around, and through, us? Robert Lawrence Kuhn explores the multiverse with the help of the world’s leading experts on these theori.
Older, but interesting idea—
Warp drive and stargate wormholes could be used for time travel to the past. That’s the surprising conclusion that controversial theoretical physicist and author Dr. Jack Sarfatti has reached from his research into dark energy and dark matter.

Awe inspiring stuff, this.
Black holes are some of the strangest objects in the universe. But, just as impenetrable a mystery? The heavy cloud cover encircling some black holes. Now, for the first time, researchers say they’ve managed to get a glimpse inside of one of those clouds. And what they found has some serious implications for our most basic understanding of black holes.
Some black holes are shielded by heavy clouds of gas and dust that are so thick that they’re impossible to see through with our telescopes. The reasons why have plagued scientists. But a brand new X-ray view taken by a joint team from NASA and the European Space Agency of galaxy NGC 1068, and the black hole that lies at its center, just changed all that.

“The detector could help to clear up some mysteries. In 2013, the AMS announced it had seen hints of dark matter but so far it has detected too few high-energy particles to say for sure. Though DAMPE lacks the equipment to resolve the conundrum directly, it could reveal if the signal is caused by a different astrophysical source, such as pulsars, says Capell.
Although it will collect fewer incoming photons, DAMPE is better at pinpointing their energy than are existing γ-ray telescopes, such as NASA’s Fermi-LAT, says Miguel Sanchez-Conde, a physicist at the Oskar Klein Centre for Cosmoparticle Physics in Stockholm. This capability should allow DAMPE to see sharp spikes in radiation predicted by some dark-matter models.”
LEAD, S.D. [Brown University] — The Large Underground Xenon (LUX) dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility (Sanford Lab) in the Black Hills of South Dakota, has already proven itself to be the most sensitive dark matter detector in the world. Now, a new set of calibration techniques employed by LUX scientists has again dramatically improved its sensitivity.
Researchers with LUX are looking for WIMPs, weakly interacting massive particles, which are among the leading candidates for dark matter. “It is vital that we continue to push the capabilities of our detector in the search for the elusive dark matter particles,” said Rick Gaitskell, professor of physics at Brown University and co-spokesperson for the LUX experiment. “We have improved the sensitivity of LUX by more than a factor of 20 for low-mass dark matter particles, significantly enhancing our ability to look for WIMPs.”
The new research is described in a paper submitted to Physical Review Letters and posted to ArXiv. The work re-examines data collected during LUX’s first three-month run in 2013, and helps to rule out the possibility of dark matter detections at low-mass ranges where other experiments had previously reported potential detections.
