Anyone hear about this?

My girlfriend's uncle who lives in Puerto Rico is on this team of scientists in Switzerland right now.

Pretty cool stuff.

PASADENA, Calif. — After 16 years and $10 billion — and a long morning of electrical groaning and sweating — there was joy in the meadows and tunnels of the Swiss-French countryside Tuesday: the world’s biggest physics machine, the Large Hadron Collider, finally began to collide subatomic particles.

Following two false starts due to electrical failures, protons whipped to more than 99 percent of the speed of light and to energy levels of 3.5 trillion electron volts apiece around a 17-mile underground magnetic racetrack outside of Geneva a little after 1 p.m. local time. They crashed together inside apartment-building sized detectors designed to capture every evanescent flash and fragment from microscopic fireballs thought to hold insights into the beginning of the world.

The soundless blooming of proton explosions was accompanied by the hoots and applause of scientists crowded into control rooms at CERN, the European Organization for Nuclear Research, which built the collider. The relief spread to bleary gatherings of particle physicists all around the world, who have collectively staked the future of their profession on the idea that the new collider will eventually reveal new secrets of the universe, like the identity of the dark matter that shapes the visible cosmos and the strange particle known as the “Higgs,” which is thought to imbue other particles with mass. Until now, these have been tantalizingly out of reach.

“We’re expecting some answers,” said David Politzer, a Nobel laureate at the California Institute of Technology, where refreshments in a conference room overflowing with Los Angeles-area physicists attending a midnight remote viewing included matzos, chips and pizza.

Rolf Heuer, director general of CERN, speaking from Japan, said the new collider “opens a new window of discovery and it brings, with patience, new knowledge of the universe and the microcosm. It shows what one can do in bringing forward knowledge.” He added: “It will also bring out an army of children and young people who will get into the private sector and academia.”

“We are all proud and so happy,” Fabiola Gianotti, a spokeswoman for CERN, said of one of the giant particle detectors at the collider, known as Atlas. Guido Tonelli, leader of a rival detector called C.M.S. said, “We are really starting physics.”

The success in colliding protons marks a remarkable comeback for CERN, but the lab is still only halfway back to where it wanted to be: Only a year and a half ago, the first attempt to start the collider ended with an explosion that left part of its tunnel enveloped in frigid helium gas and soot when an electrical connection between two of the powerful magnets that steer the protons vaporized. A subsequent investigation revealed that the collider is riddled with thousands of such joints, the result of what Lucio Rossi, head of magnets at CERN, said stemmed from a “lack of adequate risk analysis” in a recent report in the online journal Superconductor Science and Technology.

As a result, the collider, which was designed to accelerate protons to 7 trillion electron volts and then smash them together to reveal particles and forces that reigned during the first trillionth of a second of time as we know it, can only be safely run for now at half power. CERN physicists say that operating the collider for a year and a half at this energy level should allow them to gather enough data to start catching up with its American rival, the trillion-volt Tevatron at the Fermi National Accelerator Laboratory in Illinois, which is smaller but has been running for years and thus has a head start in data. After that, the CERN machine will shut down for a year so that the connections can be rebuilt.

Particle colliders get their oomph from Einstein’s equation of mass and energy. The more energy — denoted in the physicists’ currency of choice, electron volts — that these machines can pack into their little fireballs, the further back in time they can go, closer and closer to the Big Bang, and the smaller and smaller things they can see.

The first modern accelerator was the cyclotron, built by Ernest Lawrence at the University of California, Berkeley, in 1932. It was a foot in diameter and boosted protons to energies of 1.25 million electron volts, the unit of choice for mass and energy in physics. By comparison, an electron, the lightest well-known particle, is about half a million electron volts, and a proton about a billion.

Over the last century, universities and then nations leapfrogged each other, building bigger machines to peer deeper into the origins of the universe. But the end was decreed in 1993, the U.S. Congress canceled the Superconducting Supercollider, a 54-mile 20-trillion-electron-volt machine being built underneath Waxahachie, Texas, after its projected cost ballooned to $11 billion.

Pocket change these days. 

I bet the house rep for the district in which Waxahachie is located could have gotten an $11 billion earmark for voting for the health care bill.  Some people just don't know how to negotiate.
