LHC: ask your questions to Etienne Klein in chat
:: 15 November, 2008
The Large Hadron Collider, LHC alias, inaugurated but not yet started, raises many questions and even some fantasies. On the occasion of the Feast of science, an eminent physicist CEA, Etienne Klein comes to your meeting Wednesday November 19 to 18 hours to respond directly to all your questions.
Buried underground, between 100 and 700 meters deep, the LHC (Large Hadron Collider), this huge particle accelerator 27 km in length, composed of several rings, accumulating records. Described as the most complex machines made by humans, it will reach the highest energies ever obtained (7 TeV). When protons collide, scientists have provided an environment increased to 2,000 billion degrees, ie conditions that existed a billionth of a second after the Big Bang ...
These opportunities are dreaming physicists, who hope this new instrument without equivalent discover some secrets of the universe. Micro black holes or dark matter may be better understood through the LHC. The realization of this gigantic machine also involves the general public, whose questions are legitimate, even when confined to fantasy.
All questions are good
What is it really? How do we know that we can approach the conditions of the Big Bang? What are mini black holes? Are they dangerous? The dark matter is it the same as black holes (confusion found in a weekly newspaper also seriously)? Is there a risk that the LHC does not find anything? How much did it cost? Is there still a lot to discover in particle physics? How does a particle accelerator of normal matter might discover dark matter?
There is no doubt that the questions regarding the LHC are numerous. Whatever the level, do not hesitate to ask. Etienne Klein, CEA physicist, he participated in the design of the LHC and is very committed to the dissemination of science, why it works with us ...
Wednesday November 19, 18 to 19 hours for the Feast of science, it will be live to answer any questions you ask. Because some require little reflection or risk being asked several times, you can think calmly and send them forward. You can simultaneously be notified one hour before the appointment, does not miss the history...
