That'll be midnight where I live.
Heheh. hehehehehHAHAHAHAHAHAHAAHAHAHAHA
Anyplace where they'll actually be broadcasting what goes on?
Also, the official study where they said that the LHC won't destroy us with microblackholes because cosmic rays collide and don't eat planets in nature? Does it happen as often in nature nearly as often as it will in the LHC?

LHC is scheduled to send the first proton beam zipping through its 27-km tunnel on September 10. Scientists expect it will take four to eight weeks to adjust the beams to produce particle collisions. They hope to observe the first collisions between October 8 and November 5.

More often, and some at far higher energies. And they have been hitting the planet for billions of years.
The LHC collisions will have about 14 TeV at full power, but some cosmic rays can get up to 1 million TeV.
Incidentally 1 million TeV is enough energy to heat one gram of water by about 0.04 degrees centigrade!
(TeV = terra electon volts.) |

The first test went without a hitch.
Here is the trace from one of the particle detectors from the first beam.

at my school a couple teachers have talked about the lhc... they think its gonna create a black hole and destroy the earth. tards
i just go, wutlol?

oh yeah, can some one here like mr palazzo (dont you have like a degree in physics) explain the lhc higgs boson, cosmic rays in a way a teacher would understand?
i tried to explain it but its a toughie

If they understand the field concept, liken the higgs field to mud. As particles interact with it in a certain way, they are burdened and gain mass.
Cosmic rays are just high-energy particles that collide with our atmosphere, we don't know the source as far as I know.

if you read the OP again, you will find that I wrote this:
The Higgs boson is crucial to SM. Here’s why. Back in the 1930’s, when people were working on quantum field theory (QFT), they were faced with a theory riddled with infinities. Dirac was the first one to work around by introducing what is called a Lagrange multiplier – a fancy name but technically is very simple, it’s just a constant. The trick is, instead of performing an integration which gives the infinity, one plugs in a constant, does the integration, which now doesn’t go to infinity, then removes the constant. It turns out this made QFT a theory of the real world, but most physicists, including Dirac, were highly unsatisfied with this math trick. Feynman was able to do the same by using graphs and looking at the path integrals by considering all possibilities. When this was applied to the electromagnetic force, quantum electrodynamics (QED) became the most precise theory on this planet.
However, this trick only works because the photon, the particle that mediates the electromagnetic force, is massless. In the weak and strong nuclear forces, the bosons have masses. When that is taken into consideration, the infinities reappear.
Higgs was able to work around this by proposing that these bosons acquire their masses by a process called spontaneous symmetry breaking – a fancy name, but it is just another math trick. The analogy is the particle on a hill. It is at rest and every direction is equal (the symmetry) But once it’s nudged, it will roll down the hill. By choosing a direction, it has broken the symmetry. In the SM, the massless boson acquires mass – that is, breaks the symmetry – by traveling through a Higgs field.
I don't know if that helps, but if you want to reduce that to a sound bite, it would be: the higgs boson gives mass to particles.
Cosmic x-rays are a real mystery. No one has been able to identify the sources of these high energy particles. Do these come from quasars, neutron stars, whatever, we simply don't know what natural phenomenon produces these.
Now at LHC, the program runs at a few TEV (a unit of energy). Cosmic x-rays hit the earth's atmosphere at millions of TEV, so the whole idea that the experiments at Cern will destroy the earth is just ludicrous. |

She was in a hurry to die and couldn't wait for the LHC to do it for her. Never question stupidity, we need it to keep populations in check.
