Scientists Say They Can Now Test String Theory

The idea of the “Theory of Everything” is enticing – that we could somehow explain all that is. String theory has been proposed since the 1960’s as a way to reconcile quantum mechanics and general relativity into such an explanation. However, the biggest criticism of String Theory is that it isn't testable. But now, a research team led by scientists from the Imperial College London unexpectedly discovered that that string theory also seems to predict the behavior of entangled quantum particles. As this prediction can be tested in the laboratory, the researchers say they can now test string theory. “If experiments prove that our predictions about quantum entanglement are correct, this will demonstrate that string theory 'works' to predict the behavior of entangled quantum systems,” said Professor Mike Duff, lead author of the study. String theory was originally developed to describe the fundamental particles and forces that make up our universe, and has a been a favorite contender among physicists to allow us to reconcile what we know about the incredibly small from particle physics with our understanding of the very large from our studies of cosmology. Using the theory to predict how entangled quantum particles behave provides the first opportunity to test string theory by experiment. But – at least for now – the scientists won’t be able to confirm that String Theory is actually the way to explain all that is, just if it actually works.” This will not be proof that string theory is the right 'theory of everything' that is being sought by cosmologists and particle physicists,” said Duff. “However, it will be very important to theoreticians because it will demonstrate whether or not string theory works, even if its application is in an unexpected and unrelated area of physics. “String theory is a theory of gravity, an extension of General Relativity, and the classical interpretation of strings and branes is that they are quantum mechanical vibrating, extended charged black holes.The theory hypothesizes that the electrons and quarks within an atom are not 0-dimensional objects, but 1-dimensional strings. These strings can move and vibrate, giving the observed particles their flavor, charge, mass and spin. The strings make closed loops unless they encounter surfaces, called D-branes, where they can open up into 1-dimensional lines. The endpoints of the string cannot break off the D-brane, but they can slide around on it. Duff said he was sitting in a conference in Tasmania where a colleague was presenting the mathematical formulae that describe quantum entanglement when he realized something. “I suddenly recognized his formulae as similar to some I had developed a few years earlier while using string theory to describe black holes. When I returned to the UK I checked my notebooks and confirmed that the maths from these very different areas was indeed identical. “Duff and his colleagues realized that the mathematical description of the pattern of entanglement between three qubits resembles the mathematical description, in string theory, of a particular class of black holes. Thus, by combining their knowledge of two of the strangest phenomena in the universe, black holes and quantum entanglement, they realized they could use string theory to produce a prediction that could be tested. Using the string theory mathematics that describes black holes, they predicted the pattern of entanglement that will occur when four qubits are entangled with one another. (The answer to this problem has not been calculated before.) Although it is technically difficult to do, the pattern of entanglement between four entangled qubits could be measured in the laboratory and the accuracy of this prediction tested. The discovery that string theory seems to make predictions about quantum entanglement is completely unexpected, but because quantum entanglement can be measured in the lab, it does mean that there is way – finally – researchers can test predictions based on string theory. But, Duff said, there is no obvious connection to explain why a theory that is being developed to describe the fundamental workings of our universe is useful for predicting the behavior of entangled quantum systems. “This may be telling us something very deep about the world we live in, or it may be no more than a quirky coincidence”, said Duff. “Either way, it's useful.” http://www.universetoday.com/72531/scientists-say-they-can-now-test-string-theor… added by: pjacobs51

A Tribe Called Quest Applaud Success Of Drake, Lupe, Kid Cudi

‘We knocked down the door,’ Phife Dawg tells MTV News at Rock the Bells stop. By Jayson Rodriguez, with reporting by Sway Calloway and Shaheem Reid Q-Tip and Phife Dawg perform at Rock the Bells Sunday Photo: Getty Images Making The Moment: Midnight Marauders A Tribe Called Quest pulled off the rare feat of dropping back-to-back-to-back classic albums in the early 1990s, with People’s Instinctive Travels and the Paths of Rhythm, The Low End Theory, and Midnight Mauraders. But while they were creating those masterpieces, they were fully unaware of the impact the group was having on hip-hop. According to Phife Dawg, ATCQ were just concerned with keeping the momentum going from one project to the next. “Gotta keep it coming,” he told MTV News. ” People’s Instinctive, we knocked down the door. Low End Theory, we knocked it off the hinges. And we just had to skyrocket after that. I don’t think we thought about it that much; we just decided to be ourselves and have fun with it. But I remember us saying to each other, ‘Let’s not make this a conceptual album — let’s just have fun. Rhyme over these beats and do what we do.’ But one important thing that we always had in mind was how the album would be sequenced, and I think that’s what really made the album banging.” While the four-man collective — Q-Tip, Phife Dawg, Ali Shaheem Muhammad and Jarobi — didn’t realize yet the place they were carving out in music history, as they reflected on their careers, Tribe, touring this month on the Rock the Bells trek, said they understand the benchmarks they’ve achieved. And in particular, the influence they’ve had on a bevy of MCs, from Lupe Fiasco to J.Cole to Kid Cudi, all whom have burrowed from Tribe’s rythmic sound and everyman raps. Tribe’s DJ and one of the group’s core producers, Ali Shaheed, said he wished there were even more room for acts with that kind of artistic slant. “There are a lot of people who are bringing a lot of technique and style out there,” he said. “Hip-hop is different these days. One thing that’s missing is that there used to be a plethora [of diverse acts]. It only feels like just a handful on the mainstream level that’s impacting, like Drake, Lupe, Kid Cudi. They each have their own fanbase, which says a lot, that people are opening their minds to follow artists like that. But I would like to see a whole lot more. There was dozens of dozens of groups making an impact when we were out there. It’d be nice to see that again on a mainstream level.” Which up-and-coming MCs most remind you of A Tribe Called Quest?

Mosque Controversy- Boyd’s Local Holy War Continues

No matter which religions are fighting, Boyd loves his country. added by: Progresshiv

Americans do be dumber.

Chances are that by now you've heard about the Aug. 19, 2010, Pew poll that found that nearly one fifth of Americans (mistakenly) believe that President Obama is a Muslim. Perhaps you think that a terrifying outlier; or perhaps you're a believer, and then you are in good company. Either way, you're wrong: in fact, remarkably high numbers of Americans believe the most unusual things. Although the portion of poll respondents who believe Obama is a Muslim has risen recently, some of these oddball opinions contain more consistent numbers of believers. Here's a sampling of the nuttiest. EVOLUTION vs CREATIONISM To mark the 200th anniversary of Charles Darwin's birth, Gallup thought it might be a good idea to poll Americans on their beliefs of the British naturalist's theory. But the results must have had Darwin spinning in his grave, since only 39 percent of Americans believed in the theory. The good news: only a quarter said they didn't believe it; the remaining portion either didn't have an opinion or didn't answer. (Also, only 55 percent correctly linked Darwin's name with the theory.) However, it appears that views may, um, evolve: younger people believe in evolution at far higher rates than older ones. WITCHCRAFT It seems obvious that it's not a good idea to put too much stock in withcraft. But it turns out that 21 percent of Americans believe there are real sorcerors, conjurers, and warlocks out there. And that's just one of the several paranormal beliefs common among Americans, according to Gallup: 41 percent believe in ESP, 32 percent in ghosts, and a quarter in astrology. In fairness, the numbers in this poll are a little old—they date back to 2005. But then again, if people haven't changed their mind since the Enlightenment, it's not clear another half decade would make much difference. DEATH PANELS From Facebook to faith: that's how a spurious rumor became part of the national dialogue. On Facebook, Sarah Palin wrote in August 2009 that Obama would institute a “death panel” as part of health-care reform. Soon pundits and politicians were demagoguing the issue into common currency. Even in August 2010, one year after the initial burst and five months after health reform was signed into law, the belief lingers. According to the Kaiser Family Foundation, four in 10 Americans mistakenly believe the Patient Protection and Affordable Care Act creates a panel that makes decisions about end-of-life care. SADDAM'S WMDs AND 9/11 INVOLVEMENT Even years after claims that Saddam Hussein had weapons of mass destruction or had links to the September 11 attacks had been debunked, not all Americans were convinced. In a June 2007 NEWSWEEK poll, four years after the invasion of Iraq, 41 percent believed Saddam was involved in 9/11—even though President Bush had said otherwise as early as September 2003. Wild views on 9/11 are in fact still rampant. In September 2009, Public Policy Polling found that a quarter of Democrats suspected Bush had something to do with the attacks. Meanwhile, many Americans also remain convinced that Saddam had WMDs, even though inspectors haven't found any in the seven years since the invasion. Still, as of 2006, half of Americans believed that, according to Harris. Who knows where they got that idea? HELIOCENTRISM Didn't we clear this one up in the 16th century? Copernicus be damned, 20 percent of Americans were still sure in 1999 that the sun revolved around the Earth. Gallup, the pollster that conducted the study, gamely tried to dress it up by celebrating the fact that “four out of five Americans know Earth revolves around the sun,” but we're not buying. HISTORY OF RELIGION If mutual understanding is the key to tolerance, we're in trouble. According to NEWSWEEK's 2007 What You Need to Know poll, barely half of Americans were correctly able to state that Judaism was older than both Christianity and Islam. Another 41 percent weren't sure; in case you're in that group, here goes: Judaism is the oldest of the Abrahamic faiths, followed by Christianity—which reveres the Jewish prophets (including Moses, above)—and then Islam, which reveres the Jewish prophets and also hails Jesus as a prophet. Supreme Court vs. Seven Dwarfs It's hard to imagine what inspired the pollsters at Zogby to ask the question, but the answer is striking: in a 2006 poll, more than three quarters of Americans could name at least two of the seven dwarfs, while not quite a quarter could name two members of the Supreme Court. NEWSWEEK's response is a split decision, if you will: on the one hand, Disney is as much a symbol of America as the high court, and those dwarfs are adorable. On the other hand, it should be easy to name only two out of a pool of nine options. Objection sustained! WORLD GEOGRAPHY Lost? Don't ask an American. Sixty-three percent of young Americans can't find Iraq on a map, despite the ongoing U.S involvement there. Nine out of 10 can't find Afghanistan—even if you give them the advantage of a map limited to Asia. And more than a third of Americans of any age can't identify the continent that's home to the Amazon River (above), the world's largest. Three Stooges vs. Three Branches What a bunch of knuckleheads: according to Zogby, the majority of Americans—three in four—can correctly identify Larry, Curly, and Moe as the Three Stooges. Only two out of five respondents, however, can correctly identify the executive, legislative, and judicial branches as the three wings of government. FREEDOM OF RELIGION Who needs constitutional constructionism? Not one in three Americans, apparently: that's the proportion that said in a 2008 First Amendment Center poll that the constitutional right to freedom of religion was never meant to apply to groups most folks think are extreme or fringe—a 10 percent increase from 2000. In 2007, two out of five Americans told the FAC that teachers should be allowed to lead prayers in public schools. You can see several years of the reports here. PRESIDENT OBAMA'S RELIGION Opponents of President Obama have been spreading false rumors about his religion for quite some time. Recently, however, it seems that the number of Americans who believe these untruths is on the rise. Among respondents to a Pew poll, 18 percent believed Obama was a Muslim, up from 11 percent in March 2009. A Time magazine poll last week found similar results: 24 percent believed he was a Muslim, while only 47 percent correctly identified him as a Christian. There's some evidence that the best indicator of belief that Obama is a Muslim is opposing him politically, casting doubt on the accuracy of the results. Then again, it wouldn't be the craziest thing Americans believe, would it? added by: UtopianSky

Linkin Park’s ‘The Catalyst’ Video: Kiss The Past Goodbye

New clip sees LP pushing the envelope even further. By James Montgomery Photo: Warner Bros. Records Linkin Park are probably one of the 10 biggest rock acts on the planet. I mention this mostly because: A) It’s true, and B) It makes everything they’ve done post- Hybrid Theory (their big breakout album) all the more admirable. They have never been afraid to push the envelope and try new things. This is easy to do if you are a band that has nothing to lose, but in LP’s case, it borders on insanity. Their albums are the kinds of things labels schedule their financial quarters around. They’re tent poles (or life preservers) meant to keep things from sagging too low or sinking too deep. The danger of alienating their fanbase is very real, and the results could be catastrophic. Still, with each successive album, Linkin Park push even further into the void, and, in the process, they leave their n

Linkin Park Get Pushed To The Limit In ‘The Catalyst’ Video

‘I think this is a little bit more of an abstract piece than what we’ve done before,’ says Mike Shinoda. By James Montgomery Mike Shinoda on the set of “The Catalyst” Photo: MTV News Linkin Park’s videos have run the gamut from the massive (the wide-screen visuals of “What I’ve Done,” the exploding soundscapes of “New Divide”) to the minimal (the dream-like macro focus of “Somewhere I Belong,” the jittery animated world of “Breaking the Habit”), but the majority of them have one thing in common: the dude sitting in the director’s chair. Since their breakout 2000 album Hybrid Theory, Linkin Park DJ Joseph Hahn has also served as the band’s primary video director. And that’s very much the case with their upcoming video for “The Catalyst,” the first single off their much-anticipated A Thousand Suns album (due September 14). But unlike previous efforts, Hahn seemed determined to push his bandmates to the limit this time around, as MTV News found out when we visited the set of the video back in June. “I think this is a little bit more of an abstract piece than what we’ve done before,” Linkin Park’s Mike Shinoda told us. “My voice is a little tired because I’m singing on this one. And it’s a lot of singing, it’s been a long day, a lot of smoke [being used]. Once again, Mr. Hahn is in the driver’s seat, and we have faith in where he’ll take us.” And judging from what we saw, Shinoda wasn’t exaggerating. Hahn filled “The Catalyst” set with enough smoke to give Cypress Hill pause, and that was just the beginning. Over the course of the day, we watched as he dunked frontman Chester Bennington in a pool of water, bounced his bandmates off trampolines and covered them in layers of multihued dust. It was a pretty grueling — not to mention messy — day … the kind of thing that required more than a little faith to get through. Then again, one of the benefits of working with a director who also plays in your band is that you know he’s got your best interests in mind. Even if it seems like he doesn’t. “Joe has directed all of our videos since, I think, the second or third one, so he’s been doing almost all the videos for our entire career,” Shinoda said. “And if it goes well, we pat him on the back, and if it’s a pain in the butt, we blame him.” “The Catalyst” video premieres at midnight August 25 (technically, the 26th) on MTV.com and VH1.com , and then on MTV, VH1, MTV2, mtvU, MTV Hits, MTV Tr3s and all MTV international territories at 8 p.m. ET/PT on August 26.

Linkin Park Say New Single ‘The Catalyst’ Is ‘A Risk, But Worth It’

‘We wanted a track that represented where the album was going to be and how it was going to work,’ says bassist Phoenix Farrell. By James Montgomery Linkin Park Photo: James Minchin Last week, gamers everywhere thrilled to the new trailer for the upcoming “Medal of Honor,” which was directed by Linkin Park ‘s Joseph Hahn and features the band’s brand-new single, “The Catalyst.” And while the trailer no doubt had “MOH” fanatics going crazy, it may have left LP fans feeling a bit confused. Because “The Catalyst” is undoubtedly unlike any song the band has ever released. A moody, synth-heavy, decidedly doomy rumination on the broken times in which we live, it seems to back up the group’s claims that their new album, A Thousand Suns, will be a drastic departure from anything they’ve done in the past. And that, according to LP bassist Dave “Phoenix” Farrell, was precisely the point. “We wanted a track that represented where the album was going to be and how it was going to work, and this was really the track to do that. … It’s a risk, but [it’s] worth it,” he told MTV News earlier this week. “We’ve known [the album is] going to be different, and if fans were expecting Hybrid Theory or Meteora, they’re going to be surprised. It’s going to take people some time to figure it out and know what to do with it.” Farrell wouldn’t go into greater detail about just how the new album, due September 14, will differ from Linkin Park’s previous efforts, but any fan with a pair of ears should be able to tell based on “The Catalyst” alone. The songs are bigger, deeper, decidedly weirder. And while Farrell didn’t exactly back up frontman Chester Bennington’s earlier claims that A Thousand Suns is a full-blown “concept” album, he didn’t really deny them either. “I’ve never liked the title ‘concept record,’ to me that holds up the idea of Tommy or The Wall. And I love those records, but this is not that,” he said. “There are a couple threads that run throughout it, but, for us, the only concept is that it’s not intended to be a collection of individual songs. It’s constructed in a way and thought of in terms of ‘How will it flow?’ I would love … in this day and age, for our fans just once to sit down and listen to it from front to back. We want it to work as an experience.” And to that end, Farrell said the band always wanted to tie “The Catalyst” into a video game of some sort. The way they see it, it only adds another layer to the experience. So when the “Medal of Honor” folks approached them, they leapt at the opportunity. Though, sadly, working with Electronic Arts — the publisher and developer of the “MOH” series — hasn’t improved their gaming skills any. But you can’t really blame LP for that. After all, they’ve been working on A Thousand Suns for a long time now. “I loved the old ‘Medal of Honor’ games, but since we’ve been working on the new album — and really, since I had kids — I’ve kind of hung it up for a while,” Farrell laughed. “It sucks because now I have a younger brother who’s 15 and when we play against each other, it’s not even competitive. It’s ridiculous. And it pisses me off. He’s laughing and sh–. He’s killing me with his knife.” Related Artists Linkin Park

Kanye West Reveals Album, Single Details During Live Chat

Yet-untitled LP is coming ‘sometime in November,’ and next single will be ‘Lost in the World’ or ‘All of the Lights.’ By Jayson Rodriguez Kanye West Photo: Getty Images A mere 140 characters can’t contain Kanye West . The Twitter newcomer took to another digital medium Friday afternoon (August 6) when he broadcast his first Ustream session from Korea, during which he spoke from a hotel balcony as the sun rose behind him. “I’m bout to get on to answer questions and chip away at my mystique one humanizing question at a time,” he tweeted before going live. West was particularly open during the 25-minute chat, revealing tentative dates for the release of his forthcoming album (“sometime in November,” he said) and the follow-up single to “Power” (either “Lost in the World” or “All of the Lights,” which he said could arrive in 20 days). The Chicago MC was killing time until he had to depart for the airport. He was upbeat throughout the chat and displayed his wacky humor, especially when he alerted his viewers that his outfit was the same one he wore in his “Flashing Lights” clip. He also touched on his latest video, the brief 90-second clip for “Power.” West said his initial plans were to create a 30- to 40-minute mini-film. But once the song leaked, he had to move fast on a new treatment. “We vibed out in my house, and I had all these references of Renaissance paintings,” he told his followers. “I always wanted to re-create the Sistine Chapel. This is not the full re-creation [though]. I still might want to do that.” What do think about Kanye West’s social-media conquests? Let us know in the comments!

Travis Barker And Fat Joe Freestyle On MTV’s ‘RapFix Live’

The Blink-182 drummer teams up with Joey Crack for an impromptu session. By Mawuse Ziegbe, with reporting by Sway Calloway Travis Barker and Fat Joe Photo: MTV News Fat Joe’s “RapFix Live” interview on Friday (August 6) was heavy on highlights. The Bronx lyricist talked about confronting hip-hop nemesis 50 Cent, his memories of the late Big Pun and his strained relationship with Remy Ma. However, one of the more surprising moments arose when rocker Travis Barker joined the Terror Squad rapper’s sit-down. Barker — at the MTV News offices for a separate interview — warmly greeted Joe, who recalled fond times with Barker’s late pals DJ AM and Lil Chris. While Travis may be best known as the drummer for rock outfits Blink-182 and +44, he’s since branched out, becoming a familiar figure in the hip-hop scene. Barker has remixed songs by stars like Soulja Boy and hit the stage with the likes of Jamie Foxx and T-Pain . Joe even dubbed him “our hip-hop drummer. He gets it in. Ain’t nobody like him.” Barker said that he’s been inspired by both rap and rock for a long time. “Ten years ago … I’d be on tour with Blink or [his band] Transplants, one of my punk rock bands, and they’d be like, ‘What are you listening to?’ They’d be expecting me to say [something] like, ‘I’m listening to Minor Threat or Sex Pistols,’ and I would say … I can’t stop listening to Low End Theory [by] Tribe Called Quest, and they’d be bummed,” Barker revealed. “That stuff changed my life when I was a kid. I’d always be real honest and upfront about it. I listen to everything. I listen to Minor Threat just as much as I listen to Tribe.” In fact, Barker is working on the solo project Give the Drummer Some, which features a major cast of hip-hop talent, including Game, Lil Wayne, Swizz Beatz, Rick Ross and Beanie Sigel. Joe said MCs respect the drummer because he’s blurring the boundaries of hip-hop and rock by bringing the two genres together. “For somebody like Travis to tell Rick Ross or Game, ‘Yo, get in the studio,’ and they get in like this [snaps fingers], it just shows how much they appreciate what he’s doing towards the culture of hip-hop or rock or whatever you wanna call it,” Joe, who recently dropped his The Darkside, Vol. 1, said. Then, the two stars demonstrated what a hip-hop and rock collabo looks like with an impromptu performance. Barker brandished the drumsticks he always keeps on hand and took it back to the schoolyard, thumping out an uptempo beat on a stiff notebook. Joe leaned back in his chair, and with casual swagger, began to rattle off a swift freestyle. “This that genocide talk/ They killing babies again/ And there’s lines around the block/ Like it’s the ’80s again/ Yeah, the dark side and you don’t wanna go to this place/ Where I got special powers/ I could punch a hole through your face,” he rhymed.
