GENEVA: The Large Hadron Collider has been stepped up to energy levels of 7 TeV per collision, half the maximum energy of the atom-smasher, opening a new era in the quest for the universe's deepest secrets, scientist said.
The European Organisation for Nuclear Research (CERN) said it had unleashed the unprecedented bursts of energy on the third attempt, as beams of protons thrust around the 27-kilometre-long accelerator collided at close to the speed of light.
"This is physics in the making, the beginning of a new era, we have collisions at 7 TeV (teralectronvolts)," said Paola Catapano, a CERN scientist and spokeswoman, referring to the record energy levels achieved.
Faltering start
CERN director-general Rolf Heuer could barely contain his excitement by video conference from Japan: "It is a fantastic moment for science."
Within an hour, physicists from dozens of countries around the world were marvelling at their initial observations, rendered graphically as colourful bursts of energy.
"What we saw within the detector was really a firework, a lot of energy, something completely different from what we have seen until now," said Fabiola Gianotti, spokeswoman for one of the biggest parts of the experiment.
The success came after a faltering start at the giant 3.9 billion euro (A$5.7 billion) machine under the Franco-Swiss border near Geneva, which is aimed at unravelling some of the outstanding secrets of the universe.
New era: 'First Physics'
But collisions among the 20 billion protons emerged in the Large Hadron Collider (LHC) at 1:06 pm local time, creating powerful but microscopic bursts of energy mimicking conditions close to the Big Bang that created the universe.
"We're within a billionth of a second of the Big Bang," CERN spokesman James Gillies said.
Cheers and applause erupted in separate control rooms as the detectors recorded the collisions of sub atomic particles on computer screen graphs.
"We're certainly going to do the same thing several times over the coming week and hundreds of times over the year," said Steve Myers, CERN's director for accelerators and technology.
Myers had likened the attempt to firing needles from either side of the Atlantic and getting them to collide half way, while the particles sped around the ring more than 5,000 times a second.
The new stage, dubbed 'First Physics', marks only the beginning of an initial 18- to 24-month series of billions of such collisions.
general re large Hadron Collider
Any tests planned with increased, untested power etc. set for "end of days" as per Mayans, Nostradamus etc just in case Murphy's law trumps scientific predictions? (Dec, 2012)

Whatever, even if they miss the date I'm sure they can wait till the next faux doomsday prediction. Since there is one every few years and guess what, were still here.
Here's one -
Fire and Ash,
As continents clash,
Instead of on Earth,
Mushrooms grow in the sky,
Then a new birth,
The people will try.
Wow, I'm a prophet.
And it only took me 10 seconds at staring into my magic computer screen.
