No, they've already sent beams round in one direction, today is the day they start colliding, hence all the uproar and fanfair.
Sorry- not true.
All the world's media is going bananas over "first beam" day at the Large Hadron Collider (LHC) - the world's most stupendous particle-punisher, which switched on this morning (following an initial hiccup which appeared to be fixed by the traditional expedient of turning it off then on again). Today, it is being strongly implied, is the moment of truth - today is the big day, when the LHC might unmask the elusive "god particle" - or alternatively destroy the world and indeed perhaps the entire universe.
There's just one snag with all that - it's cobblers. All the good, interesting stuff from the LHC - the Higgs deiton, the dark matter, the possibly planet-gobbling black hole dimensional portal threat and/or universe-buster runaway strangelet or monopole soup plagues, dessert topping apocalypses etc - none of that's on offer today. All of these excellent possibilities require the LHC boffins to actually collide some hadrons - well, duh. The clue's in the name. But they aren't ready for that yet.
What's happening today is the inaugural, gentle bowling of some initial protons around the entire 27-km subterranean ultrachilled superconductor magno-track. That's your lot.
In coming months the underground Alpine boffinry chiefs, once happy that they have hadrons whipping round the big ring properly in one direction, will fire up the opposing stream going the other way.
Only then, once the two unprecedentedly puissant particle cannons are reliably ripping out clips of protons on full auto both clockwise and anticlockwise, will the real fun begin. Only then will the boffins begin to seriously meddle with the very fabric of the universe, as they possibly rashly cross the streams of the two colossal energy guns, ramming protons into one another at almost light speed. Thus far, we are told only that this will happen "by the end of the year".
