Scientists at CERN appear to have found it yesterday. A helpful video from a few months back explains it:
Lawrence Krauss is excited:
[T]he Higgs field implies that otherwise seemingly empty space is much richer and weirder than we could have imagined even a century ago, and in fact that we cannot understand our own existence without understanding “emptiness” better. Readers of mine will know that as a physicist, I have been particularly interested in “nothing” in all of its forms and its relation to something—namely us. The discovery of the Higgs says that “nothing” is getting ever more interesting.
Robert Wright confesses that he doesn't understand the new particle:
I personally continue to have no idea what the Higgs boson is. And I think the physicists who 'understand' what it is can do so only because they don't have the layperson's compulsion to think about the world in ways that are ultimately metaphorical. Or, at least, these physicists have dropped the idea that to truly understand something is to have a crystal-clear metaphor in your mind, a metaphor that doesn't break down at any point and doesn't contain internal contradictions. For them, apprehending a purely mathematical description of something is tantamount to comprehending it.
The discovery cost Stephen Hawking $100.
