Large Hadron Collider

Large Hadron Collider (LHC)

The LHC is back up and running- sorta! It may take 1-3 years (can you say 2012?) before we know some of the critical information that the LHC, in Cern, can tell us. Evidence of supersymmetry, the idea that every particle has a “super partner” with similar properties in a quantum dimension (according to some physics theories, there are hidden dimensions in the universe), could be discovered one way or the other before 2012.

“The LHC is back,” the European Organization for Nuclear Research announced triumphantly Friday, as the world’s largest particle accelerator resumed operation more than a year after an electrical failure shut it down.

Restarting the Large Hadron Collider — the $10 billion research tool’s full name — has been “a herculean effort,” CERN’s director for accelerators, Steve Myers, said in a statement announcing the success. Experiments at the LHC may help answer fundamental questions such as why Albert Einstein’s theory of relativity — which describes the world on a large scale — doesn’t jibe with quantum mechanics, which deals with matter far too small to see.

Of course, quantum physics is standing most scientists on their heads these days. 🙂

Physicists established a circulating proton beam in the LHC’s 17-mile tunnel at 10 p.m. (4 p.m. ET) Friday, CERN said, a critical step towards getting results from the accelerator. “It’s great to see beam circulating in the LHC again,” said CERN Director General Rolf Heuer. “We’ve still got some way to go before physics can begin, but with this milestone we’re well on the way.”

Located underground on the border of Switzerland and France, the LHC has been inching towards operation since the summer. It reached its operating temperature — 271 degrees below zero Celsius — on October 8 and particles were injected on October 23. Now that a beam is circulating, the next step is low-energy collisions, which should begin in about a week, CERN said. High-energy collisions will follow next year.

Might we create a “black hole” with this monster? Doubtful, but then, who knows anything for sure these days?

Beams collided at 7 TeV in the LHC

Geneva, 30 March 2010. Beams collided at 7 TeV in the LHC at 13:06 CEST, marking the start of the LHC research programme. Particle physicists around the world are looking forward to a potentially rich harvest of new physics as the LHC begins its first long run at an energy three and a half times higher than previously achieved at a particle accelerator.

“It’s a great day to be a particle physicist,” said CERN Director General Rolf Heuer. “A lot of people have waited a long time for this moment, but their patience and dedication is starting to pay dividends.”

The Large Hadron Collider is to close

The Large Hadron Collider is to close for a year to repair mistakes made in construction.

It is the latest in a series of setbacks to hit the atom smasher that scientists hope will re-create the Big Bang and pinpoint the Higgs boson, the so-called ”God particle”.

Scientists have discovered that copper connectors are unlikely to handle the maximum output and so will close the machine at the end of 2011 to fix the connectors.

In the meantime they will run the $A8.16 billion accelerator at half power.

Dr Steve Myers, a director of the European Organisation for Nuclear Research, which built the collider, said: ”We are pushing technologies towards their limits.”

Big Bang Machine – Will the big bang machine or black hole machine destroy the world in 2010?

i mean ive been going crazy about 2012 and this site has helped me a lot about what the calender means so uh well thanks a lot guys but well i searched black hole machine and someone said they will launch next year in 2012 in september? please help me undertsand im so confused and scared all the time.

You’re probably talking about the scare-stories some people are throwing around about the Large Hadron Collider, a new and very high energy accelerator.

That seems to be the latest thing every time there’s a new higher-energy accelerator experiment planned. “OMG OMG they’re going to make a black hole and destroy the earth” or “OMG OMG they’re going to re-create the Big Bang and destroy the earth”. None of this has any actual basis in physics, it’s just half-baked misunderstandings based on misreadings of something from the press releases.

Then the experiment happens and the scare stories subside. Then there’s a new accelerator experiment planned and it starts all over again.

This is all just as unscientific and nonsensical as the 2012 stuff. The difference is that there are a couple of people with scientific background who apparently appear on these scare sites. However, their scientific background tends to be in non-physics fields such as botany. They don’t know any more about the physics than the average layman.

Lhc – Quarks, Big Bang and Large Hadron Collider (LHC)

People are curios. Curiosity is one of the key elements that drives humanity towards the answers about our existence and our future. Since ancient times people have asked themselves about the origins of everything. From universe to the basic elements of the matter. Some people many thousands years ago assumed that if you divide some piece of matter this division must come to an end. This process should end with the basic, indivisible elements that constitute matter–atoms.

In the last centuries many experiments have confirmed that the matter is indeed consisted of some small particles. Scientific approach has contributed to the discovery of various natural and synthetic substances, molecules, chemical elements and atoms. Atoms, once believed to be indivisible, were also found to have some hard nucleus with electrons orbiting around it. Then it was discovered that the atom nucleus is consisted of protons and neutrons. So the atoms are divisible. This fact had many consequences. One of them with the most notable effect is fission nuclear bomb. However, the division story didn’t end there. Protons and neutrons were also found to contain some smaller particles–quarks.

Currently the list of all elementary particles is pretty long. This list is part of the Standard model–a model of how everything exists and interacts. It is believed that this model is not the final picture of the universe. There are still some unanswered questions. On the other hand, the universe itself is a subject of investigation. One of the key discoveries was that the universe is expanding. From this fact we can conclude that in the past the universe was smaller. The more we go into the past, the smaller it was. Sooner or later we come to the moment in time where the universe was infinitely small. This is called the Big Bang–the moment when the universe started to develop as we know it today, some 13.7 billion years ago. This is now the leading theory about the evolution of the universe. It is still unknown what banged, how and why.

The latest project to find some missing answers is the Large Hadron Collider (LHC) in CERN, Geneva. It is a giant ring 100 meters under ground where two beams of particles close to light speed will collide. Each collision will produce an enormous amount of other particles. Analysis of this debris will hopefully answer some questions about the nature of particles or even bring some new ones. Because of enormous collision energy (about 14 TeV) the circumstances will be close to the situation immediately after big bang. The LHC project is currently the largest and the most expensive scientific project.

Answering questions about micro and macro world will not only satisfy our curiosity but will also help us to understand the world. If we understand the world then we can make it better. And better world is a dream of everybody.
