LHC ready at CERN

Geneva, 26 April 2007. A ceremony was held at CERN1 today to mark the end of a crucial phase of installation of the Large Hadron Collider (LHC). A large dipole magnet was symbolically lowered into the tunnel at 12:00. This completes the basic installation of the more than 1700 magnets that make up the collider, which measures 27 km in circumference and is scheduled to be commissioned at the end of 2007.

It seems that they are about to finish that huge collider.I'm pretty sure it gonna need some fine tuning so i guess the LHC is going online very soon. Does anyone up here have a idea on what they could reveal with this new toy???
As i heard there are also some fears of the whole project being way to dangerous.

"Ready" is an interesting choice of words. While they may have installed the last major component, there are still issues that they have to deal with before they can finally fire up the Collider and get down to learning about the universe. It is estimated that it will be early next year before they can conduct reduced energy experiments. Not long ago they had a major systems failure that they are still working on solving. You can read about the problem here, along with a good deal of information on how the system works: LHC system Failure

Once they solve all the mechanical problems we will be able to study the nature of the universe in astounding new ways. It is hoped that the collider will produce the elusive Higgs boson particle, which is sometimes called the "God Particle." If they can indeed produce and study them, it could explain how other elementary particles gain mass and thus give us a better understanding of The Standard Model theory, by filling in the missing pieces of the equation.

From Wikipedia:

When in operation, about seven thousand scientists from eighty countries will have access to the LHC, the largest national contingent (seven hundred) being from the United States. Physicists hope to use the collider to enhance their ability to answer the following questions:
Is the popular Higgs mechanism for generating elementary particle masses in the Standard Model violated? If not, how many Higgs bosons are there, and what are their masses?[2]
Will the more precise measurements of the masses of baryons continue to be mutually consistent within the Standard Model?
Do particles have supersymmetric ("SUSY") partners?
Why are there apparent violations of the symmetry between matter and antimatter?
Are there extra dimensions, as predicted by various models inspired by string theory, and can we "see" them?
What is the nature of dark matter and dark energy?
Why is gravity so many orders of magnitude weaker than the other three fundamental forces?

Hope this answers some of your curiosity. The LHC is a very cool system. They have all ready created a spot on Earth that is colder than Space. I look forward to seeing this Gizmo fire up!
