“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.””
It appears that the standard tools used to identify chaotic signatures might be missing lots of hidden chaos — especially in systems that seem like they’re not chaotic at all.
Chaos theory is famously associated with so-called “strange attractors,” marked by a telltale butterfly-wing shape (see above). But according to a new paper by two University of Maryland mathematicians, sometimes chaos looks more like “a strange repeller,” or something else entirely.

Our interstellar challenge is, how do we as a planet confined humans, become an interstellar species? This encompasses all human endeavors, and is vitally dependent upon interstellar propulsion physics to realize our coming of age as an interstellar species.
There are so many competing ideas on how to realize interstellar propulsion. These include chemical rockets, ion propulsion, nuclear engines, solar sails, atomic bomb pulse detonation, antimatter drives, small black holes, warp drives and much more.
How do we sift through all these competing ideas?
For his objectivity and courage in stating that mathematics has become so sophisticated that it can now be used to prove anything, I have named the approach to solving this interstellar challenge the Kline Directive, in honor of the late Prof. Morris Kline.
A team of physicists has taken a step toward making the essential building block of quantum computers out of pure light. Their advance has to do with logic gates that perform operations on input data to create new outputs.
(Phys.org)—A trio of physicists with the Autonomous University of Barcelona has built what they claim is the first artificial magnetic wormhole. In their paper published in the journal Scientific Reports, Jordi Prat-Camps, Carles Navau and Alvaro Sanchez describe how they built the device and why they believe it might prove useful in building a more user-friendly MRI machine.
One of the unsung workhorses of modern technology is the humble interconnect. This is essentially a wire or set of wires that link one part of an electronic system to another. In ordinary silicon chips, interconnect can take up most of the area of a chip; and the speed and efficiency with which information can travel along these interconnects, is a major limiting factor in computing performance.
So it’s no wonder that physicists and engineers are creating new generations of interconnect that will become the backbone of information processing machines of the future.
July, 2015; as you know.. was the all systems go for the CERNs Large Hadron Collider (LHC). On a Saturday evening, proton collisions resumed at the LHC and the experiments began collecting data once again. With the observation of the Higgs already in our back pocket — It was time to turn up the dial and push the LHC into double digit (TeV) energy levels. From a personal standpoint, I didn’t blink an eye hearing that large amounts of Data was being collected at every turn. BUT, I was quite surprised to learn at the ‘Amount’ being collected and processed each day — About One Petabyte.
Approximately 600 million times per second, particles collide within the (LHC). The digitized summary is recorded as a “collision event”. Physicists must then sift through the 30 petabytes or so of data produced annually to determine if the collisions have thrown up any interesting physics. Needless to say — The Hunt is On!
The Data Center processes about one Petabyte of data every day — the equivalent of around 210,000 DVDs. The center hosts 11,000 servers with 100,000 processor cores. Some 6000 changes in the database are performed every second.

Physicists have created a so-called magnetic wormhole that transports a magnetic field from one point to the other without being detected.
Professor Kheifets and Dr. Igor Ivanov, from the ANU Research School of Physics and Engineering, and An international team of scientists studying ultrafast physics have solved a mystery of quantum mechanics, and found that quantum tunneling is an instantaneous process.
From CNN—The universe came in with the biggest bang ever. But now, with a drooping fizzle, it is in its swan song. The conclusion of a new astronomical study pulls no punches on this: “The Universe is slowly dying,” it reads.
Astronomers have believed as much for years, but the new findings establish the cosmos’ decline with unprecedented precision. An international team of 100 scientists used data from the world’s most powerful telescopes — based on land and in space — to study energy coming from more than 200,000 galaxies in a large sliver of the observable universe. [Full story below or at CNN.com]…
Based on those observations, they have confirmed the cosmos is radiating only half as much energy as it was 2 billion years ago. The astronomers published their study on Monday on the website of the European Southern Observatory.
The team checked the energy across a broad spectrum of lightwaves and other electromagnetic radiation and says it is fading through all wavelengths, from ultraviolet to far infrared.
