Cosmology Particle physics Physics World As with WMAP, the previous CMB space-based mission, Planck has found almost perfect agreement with inflationary models and the standard model of cosmology Known as "lambda-CMD" (lambda cold dark matter), this model describes a flat, homogenous universe dominated by dark matter and dark energy "There is little doubt that we have now uncovered a fundamental truth of the universe,"says George Efstathiou of the University of Cambridge, speaking at the ESA press conference Planck updates WMAP Cosmology Particle physics Physics World Back in March, the team behind the European Space Agency's Planck telescope released the most accurate map to date of the cosmic microwave background (CMB) – the relic radiation left over from the Big Bang As well as putting tighter constraints on the age of the universe and its contents, the findings also strongly support the idea that the early universe underwent a rapid growth spurt known as inflation In the first tiny fraction of a second, the infant universe swelled by a factor of 1078. Physicists' simplest explanation is that a single field – the inflaton – provided the mechanism for this exponential increase. Natural quantum fluctuations within the inflaton would have been blown up too and are now imprinted as the speckled temperature variations seen in Planck's CMB map Planck telescope Quantum gravity Perimeter Institute Audience night Questions from the audience to various experts This image was computer generated, depicting quantum geometry in loop quantum gravity, from answers by Thomas Thiemann View the video Quantum foundations Physics World David Deutsch's book "The Beginning of Infinity: Explanations that Transform the World" reviewed :  You may need to log in,  According to the quantum-information theorist David Deutsch, our modern understanding of how the world works has provided us with "good explanations" that open up essentially infinite possibilities for future progress. One of these explanations is the idea of the quantum multiverse, which Deutsch discussed in the May 2011 issue of Physics World (pp34–38, print version only) and to which he devotes a chapter in his book "The Beginning of Infinity" The Multiverse Optics Physics World Scientists learn how to twist light : Siyuan Yu of Bristol University and colleagues are working on changing the OAM values associated with a particular wavelength by varying the refractive index of the rings electrically. Indeed, he says that they aim to produce devices that can emit different OAM values at the same time. This, he claims, could enhance telecommunication bandwidth, by increasing the number of channels available, and boost the power of quantum computers – devices, still under development, that promise much faster data crunching by processing multiple quantum states simultaneously. "Currently, quantum computers rely on electron spin or photon spin, which only have two states, whereas OAM has many states," he explains Chip twists light Science - detailed article Particle  Physics Physics World Watch the video of the search for the Higgs particle and other topics at CERN Competing research methods will give a way to verify statistical searches Higgs particle search at CERN Watch Higgs video Perimeter Institute What is next for Higgs Quantum Computing Physics World Error correction technique could make quantum computing a step closer Based on data clusters of 8 highly entangled photons Quantum computing moves closer arXiV.org download Inner space cosmology particle physics CERN Lead ions - latest ALICE / ATLAS programme with heavier, more energetic beams For latest news from Pb ions at CERN,   click the link . . .

From supersymmetric string theory, space is composed of tiny, tiny 10-dimensional strings with our 4D world appearing like ripples on the surface of a pond as viewed from below. The world below is special - curled up in tiny 6-dimensional balls called Calabi-Yau spaces. From loop quantum gravity we have results that length, area, volume and entropy in black holes are discrete - multiples of very small units of each - everything is ultimately constrained by the geometry at small scales as depicted by the image.

First step to transport the state of spin or polarisation of electrons. Then to more complex structures such as 100 atom molecules, then to live objects This sounds like complete science fiction, but is provably possible - along with saving the planet, this will ultimately enable humans to survive and explore the cosmos by using quantum compters like Orac from Blake's seven The main difficulty is to stop the environment from interfering - hence the problems retrieving Captain Kirk at times . .

The image is awesome because it is what it looks like - a star being born Every organic lifeform also starts here because stars provide the heavier than Helium atomic elements required in living systems. Eventually stars die and give back lots of matter and energy.

Wikipedia Hubblesite.org Space cosmology Starburst galaxy M82 Starburst galaxy M82 is remarkable for its bright blue disk, webs of shredded clouds, and fiery-looking plumes of glowing hydrogen blasting out of its central regions. Throughout the galaxy's center, young stars are being born 10 times faster than they are inside our entire Milky Way Galaxy. The resulting huge concentration of young stars carved into the gas and dust at the galaxy's center. The fierce galactic superwind generated from these stars compresses enough gas to make millions of more stars. In M82, young stars are crammed into tiny but massive star clusters. These, in turn, congregate by the dozens to make the bright patches, or "starburst clumps," in the central parts of M82. The clusters in the clumps can only be distinguished in the sharp Hubble images. Most of the pale, white objects sprinkled around the body of M82 that look like fuzzy stars are actually individual star clusters about 20 light-years across and contain up to a million stars.

These Hubble images directly challenge old ideas about the last stages in the lives of stars. By observing Sun-like stars as they approach their deaths, shows that our Sun's fate probably will be more interesting, complex, and striking than astronomers imagined just a few years ago. Though approaching the violence of an explosion, the ejection of gas from the dying star at the center of Mz 3 has intriguing symmetrical patterns unlike the chaotic patterns expected from an ordinary explosion. Scientists using Hubble would like to understand how a spherical star can produce such prominent, non-spherical symmetries in the gas that it ejects. Hubblesite.org Space cosmology astronomy The Little  Ghost Nebula The Little Ghost Nebula resides the constellation Ophiuchus, between 2,000 and 5,000 light-years away. When a star with a mass similar to that of our own Sun nears the end of its lifetime, it expands in size to become a red giant. The red-giant stage ends when the star expels its outer layers into space, producing a faintly glowing nebula. The remnant stellar core in the center is now sending out a flood of ultraviolet (UV) light into the surrounding gas. The prominent blue-green ring, nearly a light-year in diameter, marks the location where the energetic UV light has stripped electrons off of atoms in the gas.
