Ya follow all that? The Higgs Boson is the theorized to be the thing behind gravity. Dark matter is currently a complete bloody mystery but the entire fate of the Universe hinges upon it.
If I was a gambling man then I reckon they’ll nab the Higgs boson. CERN have quite a track record at this sort of thing. They discovered the W and Z bosons confirming the Salam/Weinburg electroweak unification and also the top quark. As to dark matter? God knows! I suspect it doesn’t exist and something vastly more interesting is going on. My real hope for the LHC is that they provide evidence for Garrett Lisi’s E8 theory and we can dump the extra dimensions of superstring theory. Lisi’s theory is exceptionally simple compare to String Theory. It is potentially accessible to a bright final year undergrad in math or physics. Well, I guess strings are too but they are not at all easy to work with. Perhaps E8 is too beautiful to be true as Kaluza-Klein was but we live in hope.
And anyway, the LHC is magnificent. The US could have had an even bigger one (oh, er missus!) but the Superconducting Super Collider was cancelled by Congress after $2bn had been spent digging tunnels for it in Ellis County, TX. Which is just bloody typical. Congress probably spend more than that on expense account lunches in a year. The Atlas detector at the LHC alone is the size of a cathedral. The kinetic energy of the proton/anti-proton streams is epic (14TeV) or enough to power a Nimitz-class carrier at a stately 8 knots. It is ready and scheduled to go live on the 21st of October. They are currently cooling it to just above absolute zero* because the superconducting magnets need that and also I’m sure the reduction in Brownian motion helps with beam focussing.
Oh and just google the rate LHC will generate data. It’s fucking awesome. It’s so much that CERN have re-jigged the internet to distribute it. ‘net 2 is fast enough to send a Blu-Ray movie from Britain to Japan in 2 seconds. Sometimes, just sometimes, we are magnificent. Bring on the Space Elevator.
*Actually you probably all have in your homes something that operates at a negative Kelvin temperature. Guess what? You probably have several of them actually. There is a reasonable chance you might have one in your car too. Or wear one to the gym or out jogging.
