Large Hadron Collider generates a ’Mini Big Bang’
2010 11 09

The Large Hadron Collider has successfully created a "mini-Big Bang" by smashing together lead ions instead of protons.
The scientists working at the enormous machine on Franco-Swiss border achieved the unique conditions on 7 November.
The experiment created temperatures a million times hotter than the centre of the Sun.
The LHC is housed in a 27km-long circular tunnel under the French-Swiss border near Geneva.
Up until now, the world’s highest-energy particle accelerator - which is run by the European Organization for Nuclear Research (Cern) - has been colliding protons, in a bid to uncover mysteries of the Universe’s formation.
Proton collisions could help spot the elusive Higgs boson particle and signs of new physical laws, such as a framework called supersymmetry.
But for the next four weeks, scientists at the LHC will concentrate on analysing the data obtained from the lead ion collisions.
This way, they hope to learn more about the plasma the Universe was made of a millionth of a second after the Big Bang, 13.7 billion years ago.
One of the accelerator’s experiments, ALICE, has been specifically designed to smash together lead ions, but the ATLAS and Compact Muon Solenoid (CMS) experiments have also switched to the new mode.
David Evans from the University of Birmingham, UK, is one of the researchers working at ALICE.
He said that the collisions obtained were able to generate the highest temperatures and densities ever produced in an experiment.
"We are thrilled with the achievement," said Dr Evans.

"This process took place in a safe, controlled environment, generating incredibly hot and dense sub-atomic fireballs with temperatures of over ten trillion degrees, a million times hotter than the centre of the Sun.
"At these temperatures even protons and neutrons, which make up the nuclei of atoms, melt resulting in a hot dense soup of quarks and gluons known as a quark-gluon plasma."
Quarks and gluons are sub-atomic particles - some of the building blocks of matter. In the state known as quark-gluon plasma, they are freed of their attraction to one another. This plasma is believed to have existed just after the Big Bang.
He explained that by studying the plasma, physicists hoped to learn more about the so-called strong force - the force that binds the nuclei of atoms together and that is responsible for 98% of their mass.
After the LHC finishes colliding lead ions, it will go back to smashing together protons once again.

Former New York Mayor Michael Bloomberg ramped up his efforts to fight gun violence on Wednesday with a plan to spend $50 million on a grassroots network to organize voters on gun control.
The initiative’s political target is the powerful pro-gun lobby, including the National Rifle Association, that spends millions of dollars each year to back gun-rights supporters.
Bloomberg’s group, called Everytown ...
