Riddle of 'God particle' could be solved by 2012: CERN (Update) Physicists said on Tuesday they believed that by the end of 2012 they could determine whether a theorised particle called the Higgs boson, which has unleashed a gruelling decades-long hunt, exists or not.
"I'm pretty confident that towards the end of 2012 we will have an answer to the Shakespeare question for the Higgs boson -- to be, or not to be? " Rolf-Dieter Heuer, director general of the European Organisation for Nuclear Research (CERN), told a press conference at Britain's Royal Society. For the First Time, Humans See Quantum Entanglement With the Naked Eye. Physicists at the University of Geneva in Switzerland have devised a new kind of quantum experiment using humans as photon detectors, and in doing so have made the quantum phenomenon of entanglement visible to the naked eye for the first time.
For those that need a primer, entanglement is that strange quantum phenomenon that links two particles across distances such that any any measurements carried out on one particle immediately changes the properties of the other--even if they are separated by the entire universe. Einstein called it "spooky action at a distance. "
The Resonance Project. Planck time. In physics, the Planck time (tP) is the unit of time in the system of natural units known as Planck units.
It is the time required for light to travel, in a vacuum, a distance of 1 Planck length. The unit is named after Max Planck, who was the first to propose it. The Planck time is defined as: ≈ 5.39106(32) × 10−44 s where: The Mind of God: The Scientific Basis for a Rational World (9780671797188): Paul Davies.

The "theory of everything" is one of the most cherished dreams of science. If it is ever discovered, it will describe the workings of the universe at the most fundamental level and thus encompass our entire understanding of nature. It would also answer such enduring puzzles as what dark matter is, the reason time flows in only one direction and how gravity works. Special relativity. Special relativity implies a wide range of consequences, which have been experimentally verified, including length contraction, time dilation, relativistic mass, mass–energy equivalence, a universal speed limit, and relativity of simultaneity.
It has replaced the conventional notion of an absolute universal time with the notion of a time that is dependent on reference frame and spatial position. Rather than an invariant time interval between two events, there is an invariant spacetime interval. Combined with other laws of physics, the two postulates of special relativity predict the equivalence of mass and energy, as expressed in the mass–energy equivalence formula E = mc2, where c is the speed of light in vacuum.

David Albert: Sure. Subquantum mechanics. The perfect crime tool: Researchers work on ‘event cloak’ By Agence France-PresseMonday, November 15, 2010 22:54 EDT PARIS — Jewelry robbers, magicians, exam cheats and practical jokers everywhere will have an interest in an offbeat idea launched by physicists on Tuesday: to make the passage of time invisible.
The scientists have conceived of a “spacetime cloak” which manipulates light and, in essence, conceals whole events from a viewer. The theory is based on censoring the flow of events, which we perceive as a stream of light particles, also called photons, that strike the retina. Fermilab Experiment Hints At Existence of Brand-New Elementary Particle. Physicists working with a Fermilab neutrino experiment may have found a new elementary particle whose behavior breaks the known laws of physics.
If correct, their results poke holes in the accepted Standard Model of particles and forces, and raise some interesting questions for the Large Hadron Collider and Tevatron experiments. The new particle could even explain the existence of dark matter. Working with Fermilab's MiniBooNE experiment — the first part of the larger planned Booster Neutrino Experiment — physicists found evidence for a fourth flavor of neutrino, according to a new paper published in Physical Review Letters. This means there could be another particle we didn't know about, and that it behaves in a way physicists didn't expect. £2.2bn superlab where scientists are creating a star on Earth.
By Daily Mail Reporter Updated: 20:10 GMT, 17 November 2010 It may look like any average building but behind closed doors could lie the answer to safe renewable energy of the future.
Here at the National Ignition Facility in Livermore California, scientists are aiming to build the world's first sustainable fusion reactor by 'creating a miniature star on Earth'. Following a series of key experiments over the last few weeks, the £2.2 billion project has inched a little closer to its goal of igniting a workable fusion reaction by 2012. Experiment: Scientists hope that their £2.2billion 'miniature star on earth' will become the world's first sustainable fusion reactor by 2012 According to the National Ignition Facility (NIF) team in Livermore, on November 2 they fired up the 192 lasers beams at the centre of the reactor and aimed them at a glass target containing tritium and deuterium gas.
