Big Bang Machine



Big Bang "machine is set to yield surprises


Scientists could begin to store information about the origins of the universe in the coming months, as well as the world's largest particle collider moving in full force next year, said Monday the project manager.
But it May not be until 2011 that what is called "Big Bang Machine - Large Hadron Collider (LHC) - straddling the French-Swiss border at CERN research center will hit its top speed, physicist Steve Myers added.
LHC - almost 10 billion U.S. dollars experiment scientists around the world - was relaunched at the weekend after a technical accident 14 months before they brought them to stop just nine days after the start-up.
Myers, CERN Director for Accelerators, told Reuters Television that the particle beams were connected to about 27 km (17-mile tunnel) on Friday, and all went smoothly.
"Everyone is very confident, because it was a tremendous start-up. We're making measurements on this machine now, it's usually just make one or two years in the business accelerator," he said.
BEGINNING OF LIFE
The main objective is to discover how the shape of the universe after the Big Bang 13.7 billion years ago that spilled regardless of the huge speed and energy that later became the sun, stars, planets, and then life itself.
But what Myers called "new surprises in physics that we can really measure" will probably have to wait until the particle beam can be a collision in the LHC maximum power.
"We will be looking to achieve ultimate power in 2011," he said.
Experiments in the previous Collider at CERN - European Organization for Nuclear Research near Geneva, at the foot of Jura Mountains in France - staged collisions of particles of energy production close to the Big Bang.
But in its full LHC should create the conditions for just one billionth of a second after the explosion of primordial be captured by a series of super-computers that will transmit data to scientists in 33 countries.
Among the permanent mysteries researchers hope to unravel the black holes in space, as anti-matter and whether there is Higgs boson
Boson is a theoretical particle thought to thing its mass, allowing it to come together. It was first advanced by Edinburgh University scientist Peter Higgs in 1964 as an explanation of how the universe was created.

















Earlier efforts to catch him at CERN and similar laboratory in the U.S. are not.
LHC relaunch was lower than the critical first attempt on September 10, 2008, where a small technical errors culminating in a massive explosion.
The blast damaged the huge magnets that pull the particles around the tunnel and smash them together. However, Myers said all precautions have been taken to ensure that it can not happen again.
He said the first collisions will be set at low power within two weeks. After two weeks break at Christmas time, the energy will increase, and then maybe again in the spring.

Scientists at CERN have tested the LHC's mettle by circulating a low-energy beam of protons


Large Hadron Collider, collider particles in the Swiss and French border that is not recreated Big Bang, but they are less ping.

Scientists in the home of the LHC at the European Organization for Nuclear Research (CERN) announced today that they sent low-energy beam of protons around the track almost every way for particle subatomic. In all directions. But it shows that the race track. approximately 17 miles around, ready for next step - the beam of protons fully expected next month.

Test out the statement last week by CERN.

LHC offline for years, following failed power between the two magnets. The failure led to the catastrophic leak of liquid helium.

Liquid helium is essential. It cools the collider's superconducting magnets where they lose all resistance to electricity. This helps to create a magnetic field more powerful than common magnets same size.

Magnetic particles using focused beams in opposite directions in the collider will be reunited until the collision. Magnets to focus the light, quiet enough to increase the likelihood that the number of collisions will occur.

Collisions are expected to show evidence of a particle called the Higgs boson - the manufacturer and white theorists Council expressed the mass to other particles. And a team of physics that they hope to find other evidence that the particles are fantastic. help explain the strange things people see the world view. things like dark energy and dark matter, such as.



Physicists hope to other areas surveyed by LHC: Special size in some theoretical universe that more than four small projects can directly experience - time and three-dimensional object physical possession and to show that the theory that four basic force of nature - electromagnetism force strong (. bound particles in the nucleus of an atom) weak force (which controls radioactive decay), and gravity - are chilled by the enforcement of all relevant events prevailed dawn of the universe.

Scientists have already shown that the first three of these forces may actually be settled. Counterweight remains unique holdout.
