Collider team examining possible component flaw that led to superluminal measurements

Scientists working at the super collider that measured neutrinos seeming to beat Einstein’s cosmic light speed barrier a few months ago say they have uncovered at least two issues with the high-tech gear used to clock the speedy particles. It could boil down to faulty wiring:

CERN live: Christmas in Geneva

And now I have to leave this exciting story and sign in to help people fix their damn computers over the phone … if anyone is seasonally inclined, contributions to my Paypal account, [email protected], might someday help free me of this dreary ball and chain. BTW, we’re tweeting up a storm on this, I’m at SAndrewDKos. @CERN: Bottom line from …

All eyes on CERN

The mystery may get a little less mysterious in this afternoon: (BBC) — Prof Stefan Soldner-Rembold, from the University of Manchester, called the quality of the LHC’s results “exceptional”, adding: “Within one year we will probably know whether the Higgs particle exists, but it is likely not going to be a Christmas present.” He told …

CERN announces an upcoming announcement and presser on Higgs

Rumors swirled today that data may have been found that supports the Higgs boson at ~126 GeV. Reliable sources have speculated the data will show a certainty, that something’s there, to about 4.2 sigma, the threshold for official detection is 5 sigma, but that only triggers many rounds of attempted confirmation. I’m told that is probably …

Baffling mystery in the Gobi Desert easily explained?

Baffling structure in the Gobi desert found on Google Maps is one of two or more, click on image for more at the Telegraph including a slideshow

Using Google maps enterprising researchers have found a network of strange grid lines on the Chinese side of the Gobi Desert. They include military vehicles and reflective substances arrayed around one of the patterns. The origin and purpose of these structures are baffling to most onlookers. But there may be a relatively mundane explanation:

The mystery of the cosmic fog

The red speck at the centre of this very deep image from the ESO Very Large Telescope shows the galaxy NTTDF-474, seen when the Universe was only 820 million years old. It is one of the most distant ever to have had its distance measured accurately, and is one of five that have been used to chart the timeline of the reionisation of the Universe about 13 billion years ago. Image: ESO/ L. Pentericci.

There has long been a theory, or perhaps its more of a hypothesis or a conjecture, that the first stars were very different from any class of star we see today. Sci-fi writers and cosmologists wonder if Very Early Massive Objects or VEMO’s might have lit up the early universe and, because of the great …

More on super-luminal neutrinos

Schematic of an early solar neutrino detecter

It appears the articles the broke yesterday about neutrinos breaking the light-speed barrier were based on solid science (I can’t believe I just wrote that!). More here: Over three years, and from 15,000 neutrino “events,” a huge detector at the Italian center deep under mountain rock recorded what OPERA spokesman Antonio Ereditato described as the …
