Large Hadron Collider

To you know what is it?? Justin told me this and i was shocked to hear this. If he didn't told me this, I wouldn't know the reason if I suddenly die.

Again, quoted from my favourite encyclopedia, Wikipedia:

The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator complex, intended to collide opposing beams of protons charged with approximately 7 TeVs of energy. Its main purpose is to explore the validity and limitations of the Standard Model, the current theoretical picture for particle physics. It is theorized the collider will produce the elusive Higgs boson, the observation of which could confirm the predictions and missing links in the Standard Model of physics and could explain how other elementary particles acquire properties such as mass.

The LHC was built by the European Organization for Nuclear Research (CERN), and lies underneath the Franco-Swiss border near Geneva, Switzerland. It is funded by and built in collaboration with over eight thousand physicists from over eighty-five countries as well as hundreds of universities and laboratories. The LHC is now operational, and in the process of being prepared for first collisions. The first beam was circulated through the collider on 10 September 2008 and the first high-energy collisions are planned to take place after the LHC is officially unveiled on 21 October 2008.

Although a few individuals have questioned the safety of the planned experiments in the media and through the courts, the consensus in the scientific community is that there is no basis for any conceivable threat from the LHC particle collisions.

The theory that wanted to proof from this experiment and the worse case from this theory:

    1. The Big Bang Theory: Scientists inadvertently make a micro black hole, and the earth is quickly erased from existence. Just kidding: scientists at CERN and elsewhere have ruled out the possibility that the LHC will create any kind of doomsday scenario. The black holes that the LHC could theoretically create don't even have enough energy to light up a light bulb. On the other hand, the U.K.'s Astronomer Royal put the odds of destroying the world at 1 in 50 million(which puts it in the realm of possibilities but still not as likely as hitting the lottery).
    2. String Theory: String theory's basic assumptions are violated. The LHC will be the first particle accelerator capable of allowing scientists to study W bosons, the elementary particle responsible for the weak force. If they don't scatter in certain ways, it'll be back to the drawing board for a generation of string theorists, or as one physicist told New Scientist, "If we see these violations, people will start working very feverishly on some sort of alternative that will produce these violations."
    3. The "Our Universe Is Not Alone" Theory: Our universe really is alone. Or even worse: it's lonely.
    4. The Dark Matter of the Universe Theory: Proudly, physicists announce that they've observed dark matter's unmistakable signature inside one of the LHC's detectors. But over the next few weeks, the reality sinks in that they've actually made a measurement mistake. Some physicists don't think that the LHC will be precise enough to measure any dark matter that it's lucky enough to create.
    5. The Standard Model of Particle Physics: The Higgs boson -- the long-postulated particle that is supposed to give mass to particles -- is finally confirmed. Sure, discovering the Higgs at the LHC would be neat, but it would basically just confirm a lot of what physicists already know, without really pushing the science: Boring. Some scientists have even said that their worst case scenario for the entire collider project would be finding the Higgs and just the Higgs.

Don't be shock if u suddenly see your ancestors
