CERN scientists say particle is no "super-Higgs" 2013-03-13T21:33:15Z It’s true; string theory is at the forefront of resolving numerous mysteries in physics, even though it has little empirical evidence to support it. The Ocarina of Time Travel, Extra Dimensions, And Branching Universes 2013-03-03T19:15:00.217Z Things get even more interesting if Einstein’s theory is only an approximation to a deeper theory, as string theory holds. Physicists Find a Backdoor Way to Do Experiments on Exotic Gravitational Physics 2012-12-18T18:15:02.807Z But some observers complained that the awards went to people who were already relatively famous and overemphasized the accomplishments of string theory, which remains experimentally untested. Stephen Hawking, CERN Physicists Receive Millions in Prize Money 2012-12-11T23:05:00Z But it would find its place in New Physics, which includes science fiction-like constructs including dark matter, dark energy, string theory and extra dimensions. Particle change hailed as major find by CERN 2012-11-12T22:42:58Z The desire to escape the mathematical headaches caused by such transformations is one motivation for string theory, which allows smooth changes in the topology of space-time, says Greene. Fairly Simple Math Could Bridge Quantum Mechanics and General Relativity 2012-11-05T19:49:46.627Z According to the math, and in order to jive with quantum mechanics, string theory asserts that we live in a universe of many dimensions, not just four. The Ocarina of Time Travel, Extra Dimensions, And Branching Universes 2013-03-03T19:15:00.217Z For example, Dr. Pretorius said, in one painting of twine segments elegantly and symmetrically looped across the black, a clear reference to string theory, one string seems to be misbehaving.

Physicists At CERN Confirm Discovery Of Elusive Higgs Particle Essential To Understanding The Universe 2012-07-04T08:37:28Z Theorists have drawn on ideas from string theory, of all places, to help explain these transitions. Quantum Horse Races and Crystals of Light 2012-06-25T17:45:03.767Z One of the problems that I consider fundamentally important is the study of thermodynamics in the extreme high temperature regime, within the framework of an ultraviolet-complete theory that contains gravity, such as string theory. 30 under 30: Exploring String Theory to Figure Out How Things Work 2012-06-19T12:45:04.337Z And now — as a reader of Professor Orzel’s blog recently suggested — on to string theory. Books on Science: ‘How to Teach Relativity to Your Dog’- Book Review - Raise a Paw if You Understand Einstein 2012-05-21T20:15:50Z At first glance, string theory, the leading candidate for a fully unified theory of nature, runs afoul of this principle. Where Do Space and Time Come From? New Theory Offers Answers, If Only Physicists Can Figure It Out 2012-04-12T21:15:02.897Z It actually goes back to the 1990s and the ferment within string theory back then, although it languished until fairly recently. The Emperor, Darth Vader, and the Ultimate Ultimate Theory of Physics 2012-04-02T22:45:02.557Z He is a proponent not just of string theory but superstring theory, and in his lecture he advanced his notion that instead of a universe we have a multiverse. Segways, String Theory and Snacks: A Report From TED 2012-02-29T14:00:42Z Evidence of supersymmetry would support M-theory, the 11-dimensional version of string theory that is the best stab so far at a “theory of everything”, uniting gravity with the other forces of nature. - The Washington Post 2012-01-17T03:55:40Z The trouble is, there wasn’t one string theory, but at least five different theories. The Courage to Be Wrong: Reading the Biography of Stephen Hawking 2012-01-08T21:45:00.227Z In fact, string theory allows for a vast number—10500—of possible “worlds” with different self-consistent sets of laws and con- stants. Inconstant Constants 2011-12-31T05:15:18.567Z Wertheim calls a 2003 conference on string theory and cosmology “by far the most surreal physics event I have ever been to.” In Physics, Telling Cranks from Experts Ain't Easy 2011-12-12T14:15:02.113Z The trouble with supersymmetry is—sort of like string theory—that there’s a thousand different ways to dice it and slice it. Where's My Higgs? LHC Physicist Joe Lykken Speaks 2011-12-08T23:15:07.953Z "The trouble is, for all we know, there might be 10,000 other ways of starting with string theory and getting the same Higgs mass, and they may differ in other respects," Lykken cautions. Has the Higgs Been Discovered? Physicists Gear Up for Watershed Announcement 2011-12-08T18:15:00.360Z And yes, he specializes in string theory, which uses such advanced and difficult math that even many physicists can't follow it. The fabric of the Cosmos 2011-12-01T09:00:00Z Yet so far string theory offers no explanation for the observed values of the constants. Inconstant Constants 2011-12-31T05:15:18.567Z An internationally renowned expert in string theory, a press release issued by IAS today says Dijkgraaf "found surprising and deep connections between matrix models, string theory, topological string theory and supersymmetric quantum field theory."

Where's My Higgs? LHC Physicist Joe Lykken Speaks 2011-12-08T23:15:07.953Z In a paper posted to the physics preprint site arXiv.org on December 5, he and his collaborators work not from supersymmetry but from an even more radical overhaul of physics: string theory. Has the Higgs Been Discovered? Physicists Gear Up for Watershed Announcement 2011-12-08T18:15:00.360Z Brian Greene, a theoretical physicist at Columbia University, is known for his popular books, which have exposed the complex ideas of string theory and to a wide audience.

Believing in Cold Fusion and the E-Cat 2011-10-30T19:18:26Z And there is also the possibility, in some versions of string theory, of particles’ taking a shortcut through another dimension. Neutrinos Find a Place in Debate and in Pop Culture 2011-10-24T19:42:47Z And condensed-matter physics, never the media darling that string theory has been, gets a new mathematical tool — and a chance to bask in new-found glamour. A meeting of disciplines: String theory finds a bench mate 2011-10-19T17:20:28.410Z "If it's in that range it's an incredible success for connecting string theory to the real world," Kane says. Has the Higgs Been Discovered? Physicists Gear Up for Watershed Announcement 2011-12-08T18:15:00.360Z The best candidate for such a unifying framework seems to be string theory.

Live Chat: Have Neutrinos Broken the Speed Limit of Light? 2011-09-28T15:24:18Z But in 1999, Son got a job at Columbia University in New York City, and heard that Starinets was doing a PhD in string theory just a few kilometres away at New York University. A meeting of disciplines: String theory finds a bench mate 2011-10-19T17:20:28.410Z He says he is confident that the upcoming LHC announcements, if they pan out as predicted, will constitute evidence for string theory. Has the Higgs Been Discovered? Physicists Gear Up for Watershed Announcement 2011-12-08T18:15:00.360Z The problem is that many sciences are nonfalsifiable, such as string theory, the neuroscience surrounding consciousness, grand economic models and the extraterrestrial hypothesis. What Is Pseudoscience? 2011-09-15T11:15:05.180Z In string theory there is a 10-dimensional “landscape” of an almost incalculable number of different universes, each of which is a solution to the basic string equations with different properties and perhaps even dimensions. On View: It?s Fashionable to Take a Trip to Another Universe 2011-07-25T21:49:47Z His publications span a broad range of topics in particle physics, gravitation, string theory, mathematical physics, and atomic physics. Live Chat: Have Neutrinos Broken the Speed Limit of Light? 2011-09-28T15:24:18Z Maldacena, now at the Institute for Advanced Study in Princeton, New Jersey, had realized that string theory predicts a mathematical equivalence between two hypothetical universes, one of which would be similar to our own. A meeting of disciplines: String theory finds a bench mate 2011-10-19T17:20:28.410Z Moreover, whether string theory can make testable predictions at all has often been the subject of debate. Has the Higgs Been Discovered? Physicists Gear Up for Watershed Announcement 2011-12-08T18:15:00.360Z Another key aspect of the new worldview derives from string theory, which is at present our best candidate for the fundamental theory of nature. The Case for Parallel Universe 2011-07-19T15:45:00.317Z This interplay has been especially spectacular in recent decades, with some of the most sophisticated mathematical advances being inspired by physics, and by string theory in particular. When Math(s) Turns Out To Be Useful 2011-07-19T11:15:04.210Z Forty years ago he co-founded string theory, which was initially derided but eventually became the leading candidate for a unified theory of nature. Leonard Susskind: The Bad Boy of Physics (preview) 2011-06-22T11:15:05.573Z "A friend of mine in nuclear physics joked that ours was the first useful paper to come out of string theory," he says. A meeting of disciplines: String theory finds a bench mate 2011-10-19T17:20:28.410Z As the name of the article implies, interest in the octonions has been rekindled by their surprising relationship to recent developments in theoretical physics, including supersymmetry, string theory and M-theory. Why 5, 8 and 24 Are the Strangest Numbers in the Universe 2011-05-04T11:15:01.927Z Inflation naturally produces the Level I multiverse, and if you add in string theory with a landscape of possible solutions, you get Level II, too. The Case for Parallel Universe 2011-07-19T15:45:00.317Z We did so in the spirit of presenting fresh ideas that are illuminating if admittedly tentative—one notable example being Scientific American’s articles on string theory in its early days. Readers Respond to "A Geometric Theory of Everything" and Other Articles 2011-04-08T13:15:02.110Z But SUSY, if its existence is established, could also offer backup for the often-contested ideas of string theory which allows for at least six more dimensions than the known four -- length, breadth, depth and time. CERN particle collisions resume 2011-03-14T15:46:56Z They have also mapped the behaviour of four-dimensional black holes in string theory to the conditions at which many materials will change phase into states other than the familiar solid, liquid and gas. A meeting of disciplines: String theory finds a bench mate 2011-10-19T17:20:28.410Z "If you asked me, 'Do I believe in string theory?'" began Greene, one of string theory's most famous proponents. String Query: Physicists Prove to Be of Many Minds about a Unified Theory of the Universe 2011-03-09T21:15:05.273Z He and his brother Herman, a Princeton professor, are celebrated twins known more for their mastery of the mathematics of hard-core string theory than for philosophic flights.

A Scientist Takes on Newton 2010-07-12T19:54:00Z The choreographer has created the piece, which takes on relativity, quantum mechanics and string theory as part of the 2010 World Science Festival this week in New York. On Dance: A Physics Lesson From Karole Armitage 2010-06-03T19:00:00Z According to even the most speculative string theory variations on black holes, the Large Hadron Collider is not strong enough to produce a black hole. A Primer on the Large Hadron Collider and Particle Physics 2010-04-04T04:10:00Z And at least part of the reason, he suspects, was a bias against sullying string theory's purity. A meeting of disciplines: String theory finds a bench mate 2011-10-19T17:20:28.410Z They fear that they will need to learn string theory to talk to them. A meeting of disciplines: String theory finds a bench mate 2011-10-19T17:20:28.410Z Similarly, experimental verification of string theory's predictions about condensed matter will not prove that strings themselves are an accurate description of reality. A meeting of disciplines: String theory finds a bench mate 2011-10-19T17:20:28.410Z But perhaps, Green argues, the connection to materials will show that people have fundamentally misunderstood what string theory is. A meeting of disciplines: String theory finds a bench mate 2011-10-19T17:20:28.410Z "Maybe string theory is not a unique theory of reality, but something deeper — a set of mathematical principles that can be used to relate all physical theories," says Green.
