ATLAS detector inside the massive collider is the size of three football fields

One of the most burning questions in the minds of many scientists is how exactly our universe started. In Geneva, 2,500 researchers came together to create one of the world’s largest particle colliders.

The Large Hadron Collider (LHC) is located 100 meters under the ground in Geneva and has a circumference of 27 km (over 16 miles). The massive LHC will be used by researchers to probe the beginnings of our universe.

Claude Leroy, a physics professor from Université de Montréal, was one of the scientists involved in the project and responsible for creating the ATLAS detector used in the collider to provide a new look at the conditions that occurred during the Big Bang and immediately following.

ATLAS is the largest of the four detectors inside the LHC and is a massive device in its own right. ATLAS is 7,000 tons in weight, 46 meters in length, and 25 meters in height.

Leroy conducted the radiation and irradiation studies to ensure ATLAS ran smoothly when in operation. Leroy also created a device called MPX, which is a small device attached throughout the LHC and ATLAS to perform real-time measurements of the spectral characteristics and composition of radiation inside and around the ATLAS detector. The device is said to capture images of what’s inside the detector and its environment like neutrons and photons.

For the LHC to operate, its components must be cooled to a superconducting state. Some components of the LHC will be cooled to minus 456 degrees Fahrenheit by cooling the magnets with liquid helium. Parts of the ATLAS device will be cooled with liquid argon to minus 312 Fahrenheit.

When in operation the LHC will collide two beams of particles at close to the speed of light in an attempt to answer what the 96% of the unknown universe is made of, why particles have mass, why nature prefers matter of antimatter, and what lies beyond Earth’s dimension.

DailyTech reported on another of the LHCs components called the Regional Calorimeter Trigger in February of 2006.

Danger?

So, I'm sure this topic has been raised a few times, but aren't a lot of people worried about the dangers of this thing? I'm all for exploration and science and I'm perfectly thrilled to risk my safety for the sake of things in many situations. Still, doing anything "high-energy" in the middle of our home seems like a less-than-great idea to me.

I read about it on Wikipedia a little and one scientist claimed that the chances of something going wrong are equatable to winning the lottery for three weeks straight... sure, this isn't at all likely but, if it does happen, potentially all of humanity dies. Can't the top-tier scientists devote their attention to getting us to the moon or Mars and carry out the experience there? With that kind of brain power, we'd only have to wait a decade or two, I imagine. My fear would be eased, at least. What about everyone else?

If 'something bad' does happen and all humanity dies, it'll happen quick enough that you won't have time to worry about it. You're better off worrying about a 747 dropping a block of blue ice on your head while you sleep.

IF something goes wrong and we create something like say a black hole, there will be little difference if the LHC is located in Switserland or on the moon...

Have any idea on what kind of energy is required to create a blackhole large enough to last long enough to engulf a planet?

Lets just say the entire planet itself does not contain the energy to create a blackhole large enough.

It cannot happen with our energy limitations.

I'm guessing here, but I think there would be a very big difference between a long-enogh lasting black-hole being formed from an LHC located in Switzerland which devoures the Earth, or an LHC on the Moon which devoures that.

If a black-hole devoured the Moon, the Earth itself wouldn't be overly affected. There might be a slight difference to the tides, and there would be some radiation from it, but it wouldn't destroy the Earth. Although we wouldn't be able to see the Moon, the same amount of matter would still be there orbiting the Earth, just compressed into a tiny space. The effect of the Moon's gravity on Earth would be essentially the same as it is now-- it would be only within a few hundred miles of the singularity that the gravity would be much higher than what it is now.

To most people, the only effect of turning the Moon into a black-hole would be that they no longer see the Moon in the sky. On the other hand, to most people, the effect of turning the Earth into a black-hole would be that they were dead :)
