There is no pink light
Sep. 27, 2013 — In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice. The achievement was reported today in Nature by a team including scientists from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University. "We still have a number of challenges before this technology becomes practical for real-world use, but eventually it would substantially reduce the size and cost of future high-energy particle colliders for exploring the world of fundamental particles and forces," said Joel England, the SLAC physicist who led the experiments. "It could also help enable compact accelerators and X-ray devices for security scanning, medical therapy and imaging, and research in biology and materials science."

If Time Were 2D… - From Quarks to Quasars Question: There are lots of articles written about trying to imagine a 4th dimension of space, but what would it be like to live in a universe with a 2nd dimension of time? The short answer: We simply don’t know. This question is a bit more complicated than talking about different spacial dimensions because we experience 3 dimensions of space , and so we can use what we know about life in one dimension (and how it changes when you have two dimensions ) to make inferences about what 4 or more dimensions would be like. But it would be extremely difficult to imagine how things behave in 2 or 3 dimensions if we lived in a one dimensional universe (we would have nothing upon which to base our inferences).
Model describes universe with no big bang, no beginning, and no end (PhysOrg.com) -- By suggesting that mass, time, and length can be converted into one another as the universe evolves, Wun-Yi Shu has proposed a new class of cosmological models that may fit observations of the universe better than the current big bang model. What this means specifically is that the new models might explain the increasing acceleration of the universe without relying on a cosmological constant such as dark energy, as well as solve or eliminate other cosmological dilemmas such as the flatness problem and the horizon problem. Shu, an associate professor at National Tsing Hua University in Taiwan, explains in a study posted at arXiv.org that the new models emerge from a new perspective of some of the most basic entities: time, space, mass, and length.
From Quarks to Quasars
Also, to add to what MattMcC1 says, it's also helpful to be clear what scientists mean when they speak of a theory. They do not use the word as lay people do--that is, to indicate an idea that may or may not be well-grounded. Rather, they arrive at a theory only after exhaustive study and experimentation, the results of which can be replicated again and again. In other words, scientific theories are well-grounded in facts and reality. The "scenario" that MattMcM1 speaks of, then, is not one based on willy-nilly calculations and wishful thinking, but on known laws and facts, taking into consideration the known characteristics of the subject at hand. An 'alternative universe' will eventually destroy ours, says Higgs researcher
Physicists have discovered a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality. “This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work. The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions. Interactions that were previously calculated with mathematical formulas thousands of terms long can now be described by computing the volume of the corresponding jewel-like “amplituhedron,” which yields an equivalent one-term expression.
Light completely stopped for a record-breaking minute - physics-math - 25 July 2013 The fastest thing in the universe has come to a complete stop for a record-breaking minute. At full pelt, light would travel about 18 million kilometres in that time – that's more than 20 round trips to the moon. "One minute is extremely, extremely long," says Thomas Krauss at the University of St Andrews, UK. "This is indeed a major milestone." The feat could allow secure quantum communications to work over long distances. While light normally travels at just under 300 million metres per second in a vacuum, physicists managed to slow it down to just 17 metres per second in 1999 and then halt it completely two years later, though only for a fraction of a second.
The Search for Antimatter
Where does the Standard Model of physics come from? Fun fact: If electrons were actually spinning, they would have to spin at a (linear, on the surface) speed that is faster than the speed of light in order to have the amount angular momentum that we call "spin". I love assigning that problem for homework. Also: When I was in graduate school, my quantum mechanics professor was a big fan of symmetry, to the point where he taught almost entirely from a group theory prospective. To this day, my first answer to any unknown question is "Symmetry?"

By Joanne Manaster From Argonne Labs comes this intriguing video demonstrating the acoustic levitation of liquids on a piece of equipment developed for NASA to simulate microgravity conditions. The acoustic levitator uses two small speakers to generate sound waves at frequencies slightly above the audible range – roughly 22 kilohertz. When the top and bottom speakers are precisely aligned, they create two sets of sound waves that perfectly interfere with each other, setting up a phenomenon known as a standing wave. At certain points along a standing wave, known as nodes, there is no net transfer of energy at all. Because the acoustic pressure from the sound waves is sufficient to cancel the effect of gravity, light objects are able to levitate when placed at the nodes.

Hunting the Higgs Now Playing: CERN live webcast. The world’s most ambitious physics endeavor has delivered: On July 4th, officials from the European Organization for Nuclear Research (CERN) announced that two major experiments using the Large Hadron Collider, an enormous circular particle accelerator buried on the border between France and Switzerland, have found preliminary evidence of the long-sought Higgs boson, a subatomic particle at the center of one of the biggest mysteries in physics: What gives matter mass? “It’s hard not to get excited by these results,” said CERN Research Director Sergio Bertolucci. “We stated last year that in 2012 we would either find a new Higgs-like particle or exclude the existence of the Standard Model Higgs. With all the necessary caution, it looks to me that we are at a branching point: the observation of this new particle indicates the path for the future towards a more detailed understanding of what we’re seeing in the data.”

Separate measurements of its properties are showing two slightly different masses, according to scientists who presented their latest data on Dec. 13.

Physicists reveal compelling evidence for the "God Particle"
Let me tell you why it is not possible for Higgs boson to be there, because there cannot be any fields in a realistic understanding of the natural world. Fields were devised in the times of Maxwell to comprehend pre quantum phenomena. Every event has to have a particle/wave explanation, no field would fill in the details where a postulation is weak. It's a non quantum sub ev world out there. Gravitation and mass are due to a very different form of particle or particles, no resemblance with Higgs. Did they really detect the Higgs Boson?

Why can't people realize that we are all subject to Natural Law. That when a physical body dies the energy that animated it leaves for another place in the natural scheme of things known or unknown. That there is no God. That God did not create man in his own image. That man created God in his own image to have dominion over other men. That reincarnation is a fact in that all energy is recycled on the death of a physical body, whatever? Physics News, Videos, Reviews and Gossip - io9
