A fantastic Horizon documentary which aired a couple weeks ago, looking at resolving the standard model theory for the big bang via an experiment in November 2007. From Wikipedia:
Large Hadron Collider (LHC) is a particle accelerator and collider located at CERN, near Geneva, Switzerland ( 46°14′00″N, 6°03′00″E). Currently under construction, the LHC is scheduled to begin operation (at reduced energies) in November 2007. Recent developments indicate that it will not be running before early 2008.[citation needed] The LHC is expected to become the world's largest and highest energy particle accelerator in 2008, when commissioning at 7 TeV is completed. The LHC is being funded and built in collaboration with over two thousand physicists from thirty-four countries, universities and laboratories.
When switched on, it is hoped that the collider will produce the elusive Higgs boson particle — often dubbed the God Particle — the observation of which could explain how other elementary particles gain mass and fill in the gap in the Standard Model theory.
The collider is contained in a 27 kilometre (17 mi) circumference tunnel located underground at a depth ranging from 50 to 150 metres.[1] The tunnel was formerly used to house the LEP, an electron-positron collider.

gluoniumsays..."don't forget the gluon!" What's really interesting is that the Tevatron may scoop the LHC in discovering the Higgs. Just 4 or 5 years ago the upper mass limit for the Higgs was around 240 GeV. Beyond the mass range the Tevatron can see. But since then, with ever finer measurement of the exact mass of the top quark (171 GeV) and the W boson (80.4 GeV) the newest upper mass limit for the Higgs (using electroweak interaction constraintns) has recently been brought down to 144 GeV! This is well within the range the Tevatron can examine. (The Higgs mass up to 114 GeV has already been ruled out.)
bluecliffsays...I can see the scientist doing an interview -
"Well, we are going to try to rip the fabric of reality itself. Hopefully a collapsing singularity will occur, destroying the universe, which will prove some of our theories, "
Eh, if this sh*t causes The Rapture the scientist are so gonna be left with egg on their faces. : )
bluecliffsays...the dangers include
* Creation of a stable black hole[7]
* Creation of strange matter that is more stable than ordinary matter
* Creation of magnetic monopoles that could catalyze proton decay
* Triggering a transition into a different quantum mechanical vacuum (see False vacuum)
But...
CERN performed a study to investigate whether such dangerous events as micro black holes, strangelets, or magnetic monopoles could occur.[8] The report concluded, "We find no basis for any conceivable threat." If black holes are produced, they are expected to evaporate almost immediately via Hawking radiation and thus be harmless. It should be noted however that this is not a wholly convincing argument because Hawking radiation is currently an untested theory. Perhaps the strongest argument for the safety of colliders such as the LHC comes from the simple fact that cosmic rays of much higher energies than the LHC can produce have been bombarding the Earth, Moon and other objects in the solar system for thousands of millions of years with no such effects.
krumzysays...Great post, its funny how they felt the need to add all the editing to make it appeal to the 20 second attention span, they could have focused more on the theory instead but i guess they would have lost the audience. Instead of focusing on what these giant particle accelerators can do for scientific theory they put alot of focus on the destruction of the earth via black hole scenario. But hey, if we manage to suck all matter on earth into an infinitely small space i say that's a testament to human ingenuity

This should fix it.

burdturglersays...This embed plays on the site it comes from, was validated here but I don't see the video:

I had actually tested this before fixing by going through the submit video process and playing the video on the confirmation part (it played).
