We found the most sought-after particle in physics. Now what?
Lawrence Krauss in Slate:
Before the Large Hadron Collider at CERN in Switzerland was turned on, there were five possibilities for what might be revealed: 1) No Higgs and nothing else, 2) a Higgs with unexpected properties and nothing else, 3) lots of other stuff but no Higgs, 4) a Higgs and lots of other stuff, and 5) a single Higgs with the properties predicted in the standard model.
Many might imagine that physicists were rooting for door No. 5 because we like to be vindicated. In fact, nothing could be further from the truth. The discovery of the Higgs validates the prediction of the standard model, and with that much of the theoretical underpinning of modern fundamental physics and cosmology. But now we are completely baffled about the origins of the standard model itself. I, for one, was rooting for no Higgs at all, because that would have meant our fundamental ideas were on the wrong track. Nothing can be more exciting than finding that we have to start from scratch and discover a whole new reality hidden.

Laurence Krauss has a rare ability to be at the same time ironic, smart, critical and funny. Irresistible.
A propos the size and cost of the LTC: "Will the next great discovery be just around the corner, to be made at a successor machine in Geneva or elsewhere? Or do we have to build an implausibly large accelerator perhaps the size of the solar system?"
And: "Just as half of the country was ecstatic in 2008 when Barack Obama was first elected—supposedly heralding the end of “business as usual” in Washington—the Higgs breakthrough appeared to herald a new era in particle physics, one that could bring us closer to a possible unified theory describing all of the fundamental forces of nature.
Unfortunately, in both cases, reality has intervened".
Lol!!
Many thanks, Abbas, for having posted this article.
Btw, one of Krauss's most splendid and mind-blowing presentations, which I've had to watch repeatedly, to get my head around it, is The Universe is Flat [52:04], in which Krauss makes the case for 'zero total energy', in a "universe dominated by nothing".
Hmmmm! : )
