Submission + - Einstein's 'Lost' Model Of the Universe Discovered 'Hiding in Plain Sight'

Hugh Pickens DOT Com writes: Dick Ahlstrom reports that Irish researchers have discovered a previously unknown model of the universe written in 1931 by physicist Albert Einstein that had been misfiled and effectively “lost” until its discovery last August while researchers been searching through a collection of Einstein’s papers put online by the Hebrew University in Jerusalem. “I was looking through drafts, but then slowly realised it was a draft of something very different,” says Dr O’Raifeartaigh. “I nearly fell off my chair. It was hidden in perfect plain sight. This particular manuscript was misfiled as a draft of something else.” In his paper, radically different from his previously known models of the universe, Einstein speculated the expanding universe could remain unchanged and in a “ steady state” because new matter was being continuously created from space. “It is what Einstein is attempting to do that would surprise most historians, because nobody had known this idea. It was later proposed by Fred Hoyle in 1948 and became controversial in the 1950s, the steady state model of the cosmos,” says O’Raifeartaigh. Hoyle argued that space could be expanding eternally and keeping a roughly constant density. It could do this by continually adding new matter, with elementary particles spontaneously popping up from space. Particles would then coalesce to form galaxies and stars, and these would appear at just the right rate to take up the extra room created by the expansion of space. Hoyle’s Universe was always infinite, so its size did not change as it expanded. It was in a ‘steady state’. “This finding confirms that Hoyle was not a crank,” says Simon Mitton. “If only Hoyle had known, he would certainly have used it to punch his opponents." Although Hoyle’s model was eventually ruled out by astronomical observations, it was at least mathematically consistent, tweaking the equations of Einstein’s general theory of relativity to provide a possible mechanism for the spontaneous generation of matter. Einstein's paper attracted no attention because Einstein abandoned it after he spotted a mistake and then didn’t publish it but the fact that Einstein experimented with the steady-state concept demonstrates Einstein's continued resistance to the idea of a Big Bang, which he at first found “abominable”, even though other theoreticians had shown it to be a natural consequence of his general theory of relativity.

Now, assume the bullet hits the ceiling and almost immediately the aircraft will start de-pressurizing (venting oxygen too) which is a very bad thing (read Hypoxia). In general, commercial aircraft are pressurized at a maximum cabin altitude equivalent to about 8,000 feet, where it is possible to breathe normally without an oxygen mask. This is when the oxygen masks come in handy as you are venting oxygen into the atmosphere.
An aircraft fuselage is not a completely sealed tank, pressurization happens by either drawing air from one or more of the engines or a separate compressor. Putting more holes in it will not suddenly stop the plane from bleeding air into the cabin.

Submission + - Big 'Ocean' Discovered Beneath Asia

anthemaniac writes: Seismic observations reveal a huge reservoir of water in Earth's mantle beneath Asia. It's actually rock saturated with water, but it's an ocean's worth of water ... as much as is in the whole Arctic Ocean. How did it get there? A slab of water-laden crust sank, and the water evaporated out when it was heated, and then it was trapped, the thinking goes. The discovery fits neatly with the region's heavy seismic activity and fits neatly with the idea that the planet's moving crustal plates are lubricated with water.

Submission + - XBOX360 Hypervisor Security Protection hacked

ACTRAiSER writes: "A recent Post on Bugtraq claims the hack of the XBOX360 Security Protection Hypervisor. It includes sample code as well. "We have discovered a vulnerability in the Xbox 360 hypervisor that allows privilege escalation into hypervisor mode. Together with a method to inject data into non-privileged memory areas, this vulnerability allows an attacker with physical access to an Xbox 360 to run arbitrary code such as alternative operating systems with full privileges and full hardware access.""

Submission + - MPAA Fires Back at AACS Decryption Utility

RulerOf writes: The AACS Decryption utility released this past December known as BackupHDDVD originally authored by Muslix64 of the Doom9 forums has received its first official DMCA Takedown Notice. It has been widely speculated that the utility itself was not an infringing piece of software due to the fact that it is merely "a textbook implementation of AACS," written with the help of documents publicly available at the AACS LA's website, and that the AACS Volume Unique Keys that the end user isn't supposed to have access to are in fact the infringing content, but it appears that such is not the case. From the thread:

"...you must input keys and then it will decrypt the encrypted content. If this is the case, than according to the language of the DMCA it does sound like it is infringing. Section 1201(a) says that it is an infringement to "circumvent a technological measure." The phrase, "circumvent a technological measure" is defined as "descramb(ling) a scrambled work or decrypt(ing) an encrypted work, ... without the authority of the copyright owner." If BackupHDDVD does in fact decrypt encrypted content than per the DMCA it needs a license to do that.

Golf-Ball Sized Hail Damages Shuttle 118

MattSparkes writes "The Shuttles March launch has been delayed to late April after golf-ball sized hail caused 7000 pits and divots in the foam that shields the fuel tank. NASA say it's the worst damage of its kind that they have ever seen, but hail is not a new problem for the agency. In 1982, a hailstorm damaged the sensitive heat shield tiles on the Columbia's wings. The damaged tiles then absorbed about 540 kilograms of rain. Once in space, the orbiter faced the Sun to allow the tiles to dry out."

Submission + - CompUSA Closing More Than 50 Percent of Stores

Zurbrick writes: "CompUSA, the computer and gadget retailer owned by Mexican billionaire Carlos Slim, said on Tuesday it would close more than half of its U.S. retail locations over the next two to three months to focus on top performing locations.

CompUSA said in a statement it would close 126 of its stores and would receive a $440 million cash capital infusion, but it was not specific as to the source of the cash. The company also said it would cut costs and restructure.

Submission + - New technique for recycling PCBs

MattSparkes writes: "PCBs from discarded computers, cellphones and other devices could be recycled less harmfully using a technique developed by researchers in China. Unlike current methods, it can be used to reclaim metals such as copper without releasing toxic fumes into the air. Only a small numbers of PCBs are currently recycled."
