Might Higgs boson be a time-traveling ne'er do well out to destroy the LHC?


We've certainly seen our fair share of crackpot theories regarding the Large Hadron Collider, and quite frankly the whole thing is becoming rather old hat. That said, when the New York Times comes up with something as far out as this, we most certainly have to share it with you. It seems that way back in July, 2007 two theoretical physicists (Danish string theory pioneer Holger Bech Nielsen and the Japanese physicist Masao Ninomiya), proposed an unlikely explanation as to why the LHC and the Superconducting Supercollider before it seem to be particularly accident prone. According to science writer Dennis Overbye, the Higgs boson (which the collider has been designed to observe) "might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather." Makes sense, right? Of course, we don't have any idea how these elementary particles might actually conduct the business of destroying equipment, but that hasn't stopped the duo from proposing a novel way to test this theory.

According to a paper published earlier this month, a simple deck of cards could be made, either out of construction paper or, if you're feeling high tech, simulated on a computer. The deck would have one card indicating that the LHC should be shut down, and a much larger number of cards (maybe 100 million or so) that indicate that everything is good to go. If you draw the death card, as it were, you can bet that the shadowy hand of the Higgs boson is stretching back in time, telling you to halt the operation. Between all this and the proposed hyperdrive propulsion tests we came across a couple days ago, things are starting to get very Philip K. Dick over at CERN. Can we make one suggestion? Instead of a random number generator, why not Tarot cards? Or a Ouija board? You know, go for a Halloween vibe.

Physicist wants to test Hyperdrive Propulsion in Large Hadron Collider

How come news can never come out of the Large Hadron Collider that doesn't remind us of our planet's impending SciFi Techno-Apocalypse(tm)? When not busy being called a doomsday machine, being bedeviled by hackers and Chuck Norris (yuck!), or just plain failing, the facility could be used to test "hyperdrive" spacecraft propulsion. Seriously! And you know what that means -- someone is planning on escaping the planet, and fast. A physicist named Franklin Felber has been musing over a little known German paper from the 1920s ("The Foundations of Physics" by David Hilbert) which states, in part, that under certain conditions a stationary mass should repel a relativistic particle. If this is true, Felber, concludes, then shouldn't a relativistic particle repel a stationary mass? According to MIT's Technology Review, the LHC would be the perfect place to test this idea: Felber could "set up a test mass next to the beam line and measure the forces on it as the particles whiz past." The experiment could be run in tandem with the collider's other work -- and who knows? Mankind may soon be on its way to the stars at near-light speeds. Let's just hope we figure this out before the robots take over.

Large Hadron Collider restart, end of the world pushed back to mid-November


Still undecided about what to do with those precious few months before the biggest doomsday since Y2K? Then you're in luck, 'cause the much anticipated / feared restart of the Large Hadron Collider has now been delayed yet again, almost exactly a month after the last delay. This time it looks like a couple of vacuum leaks are the culprit, and CERN says that the collider is now unlikely to restart before mid-November, which just so happens to coincide with the peak of the Leonids meteor shower. Coincidence? Yes, yes it is.

Acoustic superlens could mask ships from sonar... in theory, anyway

Man, the mad scientists are really on a roll of late. First we hear that Li-ion cells are set to magically double in capacity, and now we're learning that a new form of invisibility cloak is totally gearing up for its Target debut. As the seemingly endless quest to bend light in such a way as to create a sheath of invisibility continues, the University of Illinois at Urbana-Champaign's Nicholas Fang has reportedly developed a metamaterial that acts as a type of acoustic superlens. In theory, at least, this approach would rely on phreaking with sound rather than light in order to intensely focus ultrasound waves; by doing so, one could hypothetically "hide ships from sonar." To be fair, this all sounds entirely more believable than hiding massive vessels from human sight, but we're still not taking our skeptic hat off until we see (er, don't see?) a little proof.

AlloSphere three story virtual environment not available for birthday parties, Bat Mitzvahs


Researchers at UC Santa Barbara are developing an immense, wholly immersive VR environment that would allow groups of researchers the opportunity to explore their data aurally and visually on a scale never before seen. The AlloSphere is a three story metal sphere housed in an echo-free chamber, large enough that twenty researchers can stand on a bridge and take a walk through an atom, for instance, or a human brain. The project relies on a supercomputer for generating real-time, high-res 3D video and audio streams from a mountain of scientific data, and currently the team is hard at work building the bad boy's computing platform and interactive display. The project leader JoAnn Kuchera-Morin has yet to state whether or not the sense of smell would be incorporated into the finished product, but we sure hope not -- that would be rather distracting, don't you think? Check it out on video after the break.

NVIDIA licenses PhysX technology for Sony's PlayStation 3


After being on the tip of gamers' tongues last summer, NVIDIA's PhysX technology has cooled a bit in terms of sheer popularity. That said, we've no doubt that the buzz will be back in force after this one clears the airwaves. NVIDIA has just announced that it has nailed down a tools and middleware license agreement for Sony's PlayStation 3, effectively bringing the aforesaid physics tech to what's arguably the most potent game console on the market today. As a result of the deal, a PhysX software development kit (SDK) is now available to registered PS3 developers as a free download for use on the SCEI Developer Network. What exactly this means for future PS3 games remains to be seen, but one's things for sure: it's only up from here.

World's largest computing grid lives to go live


Contrary to popular belief, the world as we know it didn't implode after the Large Hadron Collider was flipped on. Sure -- someone, somewhere is growing a ninth arm and trying desperately to land a cameo on Fringe, but the planet at large is still humming along just fine. Now, the world's most ginormous computing grid (the Worldwide LHC Computing Grid, or WLCG) has gone live, and the gurus behind it are celebrating the beginning of its momentous data challenge: to analyze and manage over 15 million gigabytes of data each year. The Grid combines the IT power of over 140 computer centers, 100,000 processors and the collaborative efforts of 33 countries. Unfortunately, there's no word on when the official WLCG-based Call of Duty 4 server will be green-lit for action, but we hear it's pretty high on the priorities list.

Physicists develop microlens with earth-shatteringly short focal length

It's hard to say when we, the consumers, will actually see any real benefit from the latest noteworthy discovery from Northeastern University, but we can only imagine that Srinivas Sridhar and team aren't wasting any time moving things forward. Said crew has recently created a "new microlens that focuses infrared light at telecommunication frequencies," and if you're looking for specifics, it can focus an infrared beam to a spot just 12-micrometers away from the surface. The science behind the discovery is probably only digestible by those that understand rocket science, but the long of short of it is this: the "research shows that it is possible to create smaller, ultra-compact infrared optical components that can be integrated into existing semiconductor technologies while not sacrificing image quality." Now that's something even the layman can appreciate.

Researchers fire most powerful antimatter beam ever

Scientists at North Carolina's PULSTAR nuclear reactor facility fired a positron bean five times stronger than any other ever created earlier this month, breaking a record previously held by a team in Germany. The antimatter device -- which apparently looks like a Star Trek warp reactor -- was developed as part of a two year project by NC State, the University of Michigan, and Oak Ridge National Labs. Now that the device is working, the team is looking for practical applications for the tech, including building an "antimatter telescope," which would allow even closer observations of atomic interactions. Or they could use it to blow up the universe. You know, whatever.

German scientists claim to have broken speed of light

We're almost terrified to hear what the physicists in the crowd have to say about this one, but a duo of German scientists have reportedly broken the speed of light. To do so, the two "set up an experiment in which microwave photons, energetic packets of light, appeared to travel instantaneously between two prisms forming the halves of a cube placed a meter apart." According to them, they were able to force light to overcome its own speed limit by utilizing a "strange phenomenon known as quantum tunneling." Dr. Gunter Nimtz was even quoted as saying that for the time being, it was the "only violation of special relativity that he knew of," and while it does indeed sound (way) too good to be true, we'll step aside and let the experts battle it out.

: As predicted, there's a high probability that these claims aren't exactly, shall we say, infallibly correct -- but at least someone's giving it a go, eh?

John Carmack doesn't believe in dedicated PPUs

John Carmack has always been vocally opposed to the concept of dedicated Physics processors for gaming PCs, but his latest statement on the topic really hammers the nail in. Talking to Boot Daily on the topic of Intel's QX6850 CPU, Carmack states that future multiple core CPUs will be able to take the strain of physics processing. Carmack does have a fair degree of interest in this area, with Ageia's PhysX card being supported on the Unreal Engine 3 platform, which happens to be developed by iD software's rival, Epic Games. If there's one thing we can be sure to garner out of this statement, it's that iD software's new gaming platform iD Tech 5 won't be one that favors dedicated physics processors.

Pierre-Gilles de Gennes, father of LCDs, passes away

We'll admit, Pierre-Gilles de Gennes didn't exactly get the ongoing credit he deserved for spearheading discoveries that gave us the liquid crystal display, and it's with regret that we convey the news that he has indeed passed away at 74. Pierre-Gilles was born in Paris where he graduated from the elite Ecole Normale Superieure school after working in "neutron scattering and magnetism before moving to the realm of supraconductors and later to liquid crystals." He went on to take home the Nobel Prize for Physics in 1991, and was even dubbed the "Isaac Newton of our time" by some of the judges. Thankfully, much of his brilliance can still be enjoyed via his 1974 book "The Physics of Liquid Crystals," and while we're sure the context is way over our heads, we can certainly appreciate the end results of his unwearying work.

Mini-Z T-ray imaging device takes home the gold

We're all about giving golf claps where they're due, and a healthy round is certainly in order for Mr. Brian Schulkin. The doctoral student in physics developed a breakthrough terahertz imaging device, dubbed a T-ray, that has already demonstrated its ability to "detect cracks in space shuttle foam, image tumors in breast tissue, and spot counterfeit watermarks on paper currency." The Mini-Z marks the first time such a powerful device has become portable in nature, weighing just five pounds and taking up about as much space as your average laptop. Taking home the first Lemelson-Rensselaer Student Prize ($30,000), Schulkin explained that this device didn't pose the same health risks as typical X-rays, and unlike ultrasound, terahertz waves can provide images and spectroscopic information without contacting an object. As expected, the patent-pending technology is already up for licensing, and has already received quite a bit of fanfare and commercial interest from larger companies. So while you may never personally encounter Brian's earth-shattering invention, we're fairly sure this young lad's working days are already drawing nigh if he so chooses.

Nanomagnetic vortices could lead to bigger hard drives, faster RAM

You know, we were sitting in our editors' meeting the other day, and we all came to a very serious consensus about our reportage these days. There's been a serious dearth of vortices in our articles, and so we're going to do our darndest to bring you more coverage of these truly awesome swirling clouds. Fortunately for us, those egghead physicists down at Rice University know how to read our minds. A team over in Houston used a scanning ion microscope to create and measure "ultra-thin circular disks of soft magnetic cobalt" ranging in diameter from one micron to 38 microns. According to a press release issued by the university, the six micron wide (about the size of a red blood cell) magnetic vortex is "a cone-like structure that's created in the magnetic field at the disk when all the magnetic moments of the atoms in the disk align into uniform concentric circles." (Whatever that means.) Lead researcher Carl Rau, professor of physics and astronomy at Rice University, said that this new advance may lead to storage densities "in the range of terabits per square inch," and went on to say that "magnetic processors" and "high-speed magnetic RAM" may also be in the works. Now that we think about it, this is probably what would happen to the offspring of Storm and Magneto too.

ATI announces CrossFire physics platform

Today ATI says Ageia's PhysX engine be damned, as they're about to spit some new competition in the burgeoning hardware physics engine market. When you take that newish Radeon X1900 XTX physics adapter and combine it all Voltron-like with twin SLI graphics adapters -- and then throw in Havok Physics API support, which they announced today at Computex -- you get what they're calling CrossFire, a 2+1 graphics configuration bent on pushing more pixels and polygons than any of us sad little Engadget editors would ever know what to do with. Being that few motherboards would support this triple PCI-E configuration (and the fact that ATI is pimping Intel's forthcoming Core 2 Duo processor platform, which is expected to be announced in the very near future), it seems like you might not yet have to worry about whether the 10,000 in-game object boost this rig will provide is actually worth handing over your hard-earned bucks for.
