End of the World? Search for God Particle.
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 TeV 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 that the collider
will produce the Higgs boson, the observation
of which could confirm the predictions and
missing links in the Standard Model, 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 already
operational and is presently in the process
of being prepared for collisions. The first
beams were 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 conceivable threat from the LHC particle
collisions.
Concerns have been raised in the media and
through the courts about the safety of the
particle physics experiments planned to take
place at the Large Hadron Collider (LHC), the
world's largest and most powerful particle
accelerator to date, built by the European
Organization for Nuclear Research (CERN) near
Geneva, in Switzerland. The claimed dangers
of the LHC particle collisions, which are
scheduled to begin on 21 October 2008,
include doomsday scenarios involving the
production of stable micro black holes or the
creation of hypothetical particles called
strangelets. The potential risks of these
unprecedented experiments were reviewed in
2003 by the LHC Safety Study Group, a group
of independent scientists, who concluded
that, like current particle experiments such
as the Relativistic Heavy Ion Collider
(RHIC), the LHC particle collisions pose no
conceivable threat.A second review of the
evidence commissioned by CERN in 2008
reaffirmed the safety of the LHC collisions
in light of further research conducted since
the 2003 assessment. The 2008 report was
reviewed and endorsed by CERN's governing
body and by the Division of Particles &
Fields of the American Physical Society and
was published in the Journal of Physics G. It
concludes that any doomsday scenarios at the
LHC are ruled out because the physical
conditions and events that will be created in
the LHC experiments occur naturally in the
universe without hazardous consequences.

Rappin' about CERN's Large Hadron Collider!

Apparently YouTube fixed the sound! Still,
Will Barras made two options trying to get
around the original problems:

Vimeo is downloadable if you log in.
There has been a lot of interest in the
original mp3, lyrics, and vocals for
remixing. You can find all that here:

There's also been interest in translation.
You can get a subtitle-free version from
Vimeo here (downloadable):

With backing track available here (with and
without Hawking-style voice):

Go ahead and translate, rap it, and post it!
Just give us a shout-out, and it's probably a
good idea to include the following credits
;-)
Images came from:
particlephysics.ac.uk, space.com, the
Institute of Physics, NASA, Symmetry, and
Marvel
I forgot Einstein Online, and they called me
out: http://www.einstein-online.info
And I forgot Physics World (dunno what I was
thinking when I put together the extra
dimensions bit). Steve Abel set me to rights
(but made no demands):

The talented dancers doubled as camera
people, with some work by Neil Dixon. Stock
footage is CERN's.
Will Barras is responsible for the killa
beats:

And thanks to MC Hawking, who first thought
of using computer-voice to bring Stephen
Hawking to the world of rap :-)

The rapper has a day job (we agree this is a
good thing) as a science writer.

They'll have a lot of data to sort. 15
million GB per year, actually. Want to get

(This video was an attempt to get round
YouTube's (shortlived) experiment with
terrible audio compression. In early August,
every video that was uploaded to YouTube had
awful sound. Thankfully, they fixed their
problem and re-encoded videos uploaded during
that time, so you should view the main video
instead)
