BBC Radio 4 will devote a day of programming to the LHC, including covering first injection of beams live on the Today programme. See the BBC website for programming, background etc.

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.

Photos of the LHC First Beam event will be posted "live" on 10 September 2008.

Engineers injected the first low-intensity proton beams into the LHC in August. But they did not go all the way around the ring.

On Wednesday, they sent a proton beam around the full circumference of the LHC tunnel.

Of course you have. You've also heard it repeated over and over that the Large Hadron Collider is the biggest, most expensive scientific instrument in history and that it's going to change our fundamental understanding of the universe.

Well, great, but what does that mean?

We break down how five major physics theories -- and the theorists who've spent their lives developing them -- may be impacted by the discoveries that could emanate from the LHC. We also provide answers to all your LHC FAQ in 140 characters or less, so you can send them to your friends on Twitter.

A 16-year-old girl in Madhya Pradesh allegedly committed suicide after watching news on channels about possibility of the end of earth following the atom-smasher experiment in Geneva that began on Wednesday.

High on the wall above the consoles and computers of the CERN control room, a blank projector screen brightened for an instant. Two small spots of light flickered suddenly in the darkness, so briefly that you could miss them by blinking.

The dozens of people crammed into the room yesterday, however, had been waiting for this moment for their entire careers. They weren’t blinking, and the place erupted into cheers and applause. After two decades of planning and construction, the Large Hadron Collider (LHC), the biggest and most expensive experiment in the history of science, was up and running.

Kritiker wie etwa der Tübinger Chaosforscher Otto Rössler befürchten, dass nach der geplanten Kollision der Teilchen ein schwarzes Loch entstehen könne, durch die die Erde ernsthaft in Gefahr geraten könne. Die Veröffentlichung dieser Theorie hatte für großes Aufsehen gesorgt, so dass die CERN-Wissenschaftler bei ihrer Öffentlichkeitsarbeit in die Defensive geraten waren.

Renowned British astrophysicist Stephen Hawking has bet 100 dollars (70 euros) that a mega-experiment this week will not find an elusive particle seen as a holy grail of cosmic science, he said Tuesday.
In the most complex scientific experiment ever undertaken, the Large Hadron Collider (LHC) will be switched on Wednesday, accelerating sub-atomic particles to nearly the speed of light before smashing them together.
