(UPDATES*) It's true, they say they have the Higgs in the bag. Big news. Just imagine the hubbub were it deemed imaginary.

Does this mean that regular physics in today's textbooks is complete? And that the Standard Model of Physics, the framers of which say they know it's somehow contradictory, ie wrong way down deep and in need of new physics, is now fully buttoned up, waxed and polished for its gold watch ceremony and see ya later we gotta newbie on the job?  Congratulations in any case to the operators of the Large Hadron Collider at the CERN lab. The billions of euros spent on it, and the bail-out employment it offered for US physicists - orphaned by failure here to stay in the high energy particle physics big leagues - are vindicated. Quick, what did the initials SSC stand for? Why are there abandoned tunnels near Waxahachie, Texas where, some time ago, this discovery could likely have occurred?

We already posted two days ago on the run of advance stories reporting confidently what the vast teams of scientists working with the LHC's two big detectors, each wrapped around a collision chamber where protons and anti-protons scream into one another, are pretty sure they have found: The Higgs Boson, Creator of Mass. The particle that theorists and experimenters were quite sure should momentarily stand distinct from its pervasive alter ego, the Higgs field,  appears to have done just that in teeny fireballs with sufficient energy and W and Z vector bosons (don't ask me more, read this 2007 Cosmic Variance primer on the hard stuff)  squirming about in close quarters .

Congratulations are also due the reporters who got the gist of it right and  ahead of the official word, thanks in part to the eagerly wagging tongues of physicists privy to their trade's private chatter. Kudos included for the Daily Mail in the UK. This is a tabloid that until fairly recently and except for its super pictures was mostly good for science presented as either horror story or comic relief . In recent months I've noticed it getting steady, sober reporting from its staffer Rob Waugh. And on Sunday its writer (as tracked on Tuesday) Rob Cooper reported that smoke signals heralded an announcement featuring an emphatic yes.

One wonders how the Nobel people will handle it. Zippity zillions of physicists did the experimental work that seems to confirm the thing  (and with a mass about what US physicists, in a final hurrah for the Tevatron at Fermilab, said the other day that it ought have but that their last tests' data could not quite offer with sufficient-sigma probability for a ta-DA!). Several coordinated the effort at CERN to nail it down, including the directors of the Atlas and CMS detectors. At a guess, one suspects the prophet of this boson and the field it embodies, Peter Higgs and he's Sir Peter already, of Edinburgh U. will get a solo trip to Stockholm. But then again, even when it was all theory he was not the only one charting the same essential possibilities. We shall just have to see.

Big show yesterday in Geneva. Stories:

One could  go on all day, and apologies to writers and editors of sterling accounts not noted. But in case ou are finding yourself bewildered by what exactly this news is all about, here is just one more...

  • The Atlantic - Robert Wright: What This Higgs Boson Thing Really Means ; Wright is of course a science writer of impeccable credentials (Three Scientists and their Gods, The Evolution of God, and other works that just happen to not bear on the so-called God Particle). This article does say a few useful things about the particle-field (or particle-wave) duality of nature but then pivots and ask what the hell does such language mean. He writes at one point, "In sum, I personally continue to have no idea what the Higgs boson is."

And thus, onward ye physicists to extra dimensions and to the greatest of remaining known unknowns: dark energy and dark matter.

Space is made of cornstarch, in other words.

Tanks, Charlie. I just had a brain wave as to why molasses seems wrong as model for interia: Because molasses is simply viscous, whereas the way space resists the motion of objects with mass (i.e. not at all, in the absence of acceleration) looks *viscoelastic*, e.g. http://www.youtube.com/watch?v=RUMX_b_m3Js

Oliver - If you ever learn a way to never forget to proofread your own stuff, fill me in. I R typos and a grammar multi-mangler. As for the substance of the gut confusion we share about what the Higgs field or boson is, the updates and a reference to a 2007 Cosmic Variance blog I've added to the post offer an inkling of what it's all about. Molasses, one suspects, opens few doors to understanding. Maybe inertia does.

"whY matter causes gravity" I meant. Got to learn to proof read.

Actually, I guess it may have to do with rest energy, since they predicted a mass for the particle, but I don't know...and don't remember reading about it.

In describing how the Higgs field is supposed to confer mass, even physicists are drawing analogy to the resistance to you feel pushing through water or molasses. How's that supposed to be mass-like? Stop pushing a mass and it will coast.

Is the Higgs in fact about any other mass-like property besides inertia? It's certainly not explaining what matter causes gravity. Does it explain why mass implies a rest energy? Or have anything at all to do with why things with mass have "substance," as NPR quoted one of Higgs' former students as saying? (It's the electrostatic repulsion of orbital electron clouds and chemical bonds that prevent you from falling through a chair--which give you and the chair substance.) My impression is the mass-giving aspect of the Higgs is totally about inertia, yet I don't know if I ever read or heard the word.
