CERN Scientists Back Alternative Climate Change Theory

File-CERN_logoFor those of you who think that all scientists subscribe to the “global warning is caused by humans” theory, some very prominent exceptions are making some noise, now led by the boffins at CERN, reports Anne Jolis in the Wall Street Journal:

In April 1990, Al Gore published an open letter in the New York Times “To Skeptics on Global Warming” in which he compared them to medieval flat-Earthers. He soon became vice president and his conviction that climate change was dominated by man-made emissions went mainstream. Western governments embarked on a new era of anti-emission regulation and poured billions into research that might justify it. As far as the average Western politician was concerned, the debate was over.

But a few physicists weren’t worrying about Al Gore in the 1990s. They were theorizing about another possible factor in climate change: charged subatomic particles from outer space, or “cosmic rays,” whose atmospheric levels appear to rise and fall with the weakness or strength of solar winds that deflect them from the earth.

Is This What God Sounds Like?

Higgs-BosonFascinating developments from the Large Hadron Collider, as the BBC reports that the so-called “God particle” has been simulated as sound:

Scientists have simulated the sounds set to be made by sub-atomic particles such as the Higgs boson when they are produced at the Large Hadron Collider.

Their aim is to develop a means for physicists at Cern to “listen to the data” and pick out the Higgs particle if and when they finally detect it.

Dr Lily Asquith modelled data from the giant Atlas experiment at the LHC. She worked with sound engineers to convert data expected from collisions at the LHC into sounds.

“If the energy is close to you, you will hear a low pitch and if it’s further away you hear a higher pitch,” the particle physicist told BBC News. “If it’s lots of energy it will be louder and if it’s just a bit of energy it will be quieter.”

The £6bn LHC machine on the Swiss-French border is designed to shed light on fundamental questions in physics.

Laser War In Space To Prove Einstein’s Theory Of Relativity

This is pretty cool science! From PopSci:

CERN’s Large Hadron Collider is currently the biggest science experiment in operation, but it may have to pass that mantle on soon enough. A collaboration between NASA and the ESA plans to launch three spacecraft into orbit around the sun 3 million miles apart, then have them shoot lasers at each other, all in the name of proving the existence of gravitational waves, the last piece of Einstein’s relativity theory that is as yet unproved.

LISA

Einstein’s general relativity predicts several things, such as gravity’s ability to bend time light and the constant speed at which gravity travels. But a means to prove the existence of gravitational waves — huge ripples in time and space that flow outwards from the collision of huge celestial bodies like black holes — has eluded scientists for years.

The Laser Interferometer Space Antenna, or LISA, aims to do just that.

CERN And The Vatican Will Study Origins Of The Universe Together

If you're among the millions of people who read Dan Brown's Illuminati-vs.-Catholic Church thriller Angels & Demons, you'll feel that the idea of the Vatican collaborating with CERN on the Large Hadron Collider project is more than a little unlikely; nonetheless, the Catholic Spirit is reporting that it's going to happen:
The Geneva-based laboratory would like to invite an astronomer from the Vatican Observatory to collaborate on studies concerning the origin of the universe, said Ugo Amaldi, a professor of medical physics and president of the TERA Foundation, which works closely with CERN in finding ways to apply atomic research in treating cancer. CERN, the European Organization for Nuclear Research, "is an international and European (facility), and to have the Vatican Observatory send some or one of its young scientists will be something that is extremely important," he said. He made his comments during a Dec. 10 Vatican press conference launching the Italian-language version of "The Heavens Proclaim," a book about the history of the Vatican and astronomy. The head of the Vatican Observatory, Jesuit Father Jose Funes, said during the book presentation that he hopes Gabriele Gionti, a young Vatican astronomer who will be ordained in June, will be involved in the CERN collaboration...

CERN’s Large Hadron Collider Making Massive Progress

The BBC reports:

Researchers working on the Large Hadron Collider (LHC) say they are delighted with the progress made since the machine restarted on Friday.

One official said the collider had done more in a few hours than it did in five days of operations last year.

The LHC is being used to smash together beams of protons in a bid to shed light on the nature of the Universe.

Housed in a 27km-long circular tunnel under the Franco-Swiss border, it is the world’s largest machine.

During the experiment, scientists will search for signs of the Higgs boson, a sub-atomic particle that is crucial to our current understanding of physics. Although it is predicted to exist, scientists have never found it.

Nuclear Engineer from CERN lab arrested for Al-Qaeda links

Adam Sage reports for The Times:

Fears that al-Qaeda is planning an attack on the nuclear industry in Europe were renewed yesterday after French secret agents arrested a physicist working at an atomic research centre.

The 32-year-old man, who was detained with his brother, 25, is suspected of providing a list of terrorist targets to North African Islamic radicals. He worked for the European Organisation for Nuclear Research (CERN) in Geneva, Switzerland, according to French police sources.

Agents were said to have intercepted messages in which the physicist, a Frenchman of Algerian origin, had suggested targets in France.

He is believed to have been in contact with members of al-Qaeda in the Islamic Maghreb, an Algerian-based terror organisation that joined Osama bin Laden’s network in 2007.
