Just to keep this informative thread alive, or maybe to avoid sanding engine cases tonight.
Pinhead, You're a little off on the atoms at the speed of sound thing. Sound travels at 750 mph, or 1.25 mps. The particles in the LHC will be traveling at nearly 186000 mps, a factor of over 10^5, or 100,000:1.
The LHC does not look like a bomb to me, anymore then my 750 looks like a CRV.
FYI...
Fission bombs, like we used in WWII, compress a block of material that is already highly radioactive to the point that a chain reaction of fissions occur due to the collision of sub atomic particles with the nuclei of the atoms within the block of fissionable material. The velocities involved are related to the speed of sound only to the extent that the compression wave generated by the explosive shell in the "Little Boy" design and the piston impactor in the "Big Boy" design travels through the block of fissionable material at "sonic" speeds.
Fusion bombs, as we set off on the Bikini Atoll, use a small fission bomb to compress fusionable material to the point that the atoms are close enough to fuse into heavier elements.
Both release energy predictable by the aforementioned E=MC^2 relationship. Just as Yuasa lead acid batteries do.
This is a simplification, and I could go on with diagrams and other graphics...but I don't want the thought police at homeland security calling me. You can Goggle it but be aware the thought police love Google and its data mining.
Meandering further...
The LHC will eventually reach energy densities a significant percentage of those predicted to have occurred a few microseconds after our universe when from "nothing" to "something"; at least from our perspective.
But who knows?
This is where such discussions intrude on religion and philosophy, an area where people use these antique belief systems to form a foundation for their understanding of the world. And why such experiments are often thought of as useless, wasted effort, even blasphemous.
Just to keep it going!
(Well, we could post a nipple per page to keep it going, but that would be surrendering to our base.)
