POPSTime to test time Yet if Hogan's ideas are right, noise associated with this fundamental fuzziness should be prominent at GEO600, a joint British and German machine operating near Hannover, Germany, that is searching for gravitational waves. These waves are thought to arise during events such as the massive cosmic collisions of black holes and neutron stars. Confirmation of the idea — which could come as experimental upgrades to GEO600 are put in place over the coming year — would be a big step towards a verifiable quantum theory of gravity, a long-sought unification of quantum mechanics (the physics of the very small) with general relativity (the physics of the very big). Hogan outlines his predictions in a paper published on 30 October in Physical Review D1.

POPSHas new physics been found at the ageing Tevatron? The CDF muons appear to have come from the decay of a particle with a mass of about 1 GeV. So could they be a signature of dark matter? "We are trying to figure that out," says Weiner. "But I would be excited by the CDF data regardless."

POPSDiscovery Of 'Broken Symmetry' At Subatomic Level Earns 2008 Nobel Prize In Physics
It has proved to be extremely useful, and Nambu’s theories permeate the Standard Model of elementary particle physics. The Model unifies the smallest building blocks of all matter and three of nature’s four forces in one single theory. The spontaneous broken symmetries that Nambu studied, differ from the broken symmetries described by Makoto Kobayashi and Toshihide Maskawa. These spontaneous occurrences seem to have existed in nature since the very beginning of the universe and came as a complete surprise when they first appeared in particle experiments in 1964. It is only in recent years that scientists have come to fully confirm the explanations that Kobayashi and Maskawa made in 1972. It is for this work that they are now awarded the Nobel Prize in Physics. They explained broken symmetry within the framework of the Standard Model, but required that the Model be extended to three families of quarks. These predicted, hypothetical new quarks have recently appeared in physics expe

POPSThe big bounce vs Big Bang Edwin Hubble and Stephen Hawking, and the discovery of Cosmic background radiation amongst other contributers drafted the Big Bang Theory, but Each knew it was a theory, and destined to be qualified significantly as our our technology and depth of understanding progresses. Big bang is a Theory, not a conclusion. Ask Stephen Hawking to consider any new theories, and evidence, and he would be delighted to consider the evidence. He's a scientist, and a Mathematician, who knows how limited our theories can be with what we know. He is looking for what happened, not what may have happened,.

POPSLarge Hadron Collider Stalled till Spring '09 This must be frustrating for physicists who have waited decades to smash particles together in exciting new ways. But those of us with (scientifically debunked) fears of being swallowed by an LHC-triggered black hole can breathe a sigh of relief. For now.

POPSFermilab Looks for Visitors from Another Dimension The prospect of extra dimensions is fascinating. ET might already be here in a neighbour dimension. :-) Estimated to cost about $15 million, the MicroBooNE tank would be located near the MiniBooNE detector at Fermilab so that it could observe the same beam of neutrinos. This past June the lab’s physics advisory committee approved the design phase for the project; if all goes well, the detector could begin operating as soon as 2011.
