Populated by so many violent and high-energy astrophysical phenomena. Place to look, though also a frightening place, she noted, because it’s That dark matter piles up in the center of galaxies, because it’s pulled In examining these so-called Fermi bubbles, Slatyer and another teamĮxcess of gamma rays emanating from the galactic center. Particle physics lying bloodied in the gutter.” Upshot, he said, is that “there are basically thousands of models of Which means we only know what dark matter isn’t.” The Later, in July, 2017, the DEAP team published its first results: “NoĬandidate particles are observed.” As Richard Gaitskell, the spokesmanįor the equally unsuccessful Large Underground Xenon detector, in theīlack Hills of South Dakota, told me, “So far we’ve always gotten a Of sorts, lighting up in the presence of dark matter. The ultra-pure argon,Ĭooled to minus 297 degrees Fahrenheit, is meant to serve as a conduit Making, was just about to become operational. See the DEAP-3600 liquid-argon detector, which, after six years in the SNOLAB visitors do that the miners call them SNOflakes.) I was there to cage, travelling downwardĪt twenty-five miles per hour. Joined a group of miners aboard the 8:05 A.M. The planet the overlying rock filters out the noisy cosmic rays that Goal is to actually observe dark-matter particles as they pass through Than a mile underground, in an active nickel-and-copper mine. The same is true at SNOLAB, in Sudbury, Ontario, a facility buried more World, the Higgs might also decay to the dark-matter particles.” So far, Instead of just decaying to these particles we know in the visible That the Higgs boson gives mass to all our fundamental particles. “One hypothesis is that the Higgs couldīe a portal connecting us to the dark world,” Buchmueller said. These partners have shown themselves at the L.H.C., researchers are now Theory, for every known particle, like an electron or quark, there’s aĬorresponding superparticle with a much greater mass.” But since none of As Swinton explains in the film, “According to this The favored model for predicting dark matter Now that the Higgsīoson is well accounted for, dark matter has become one of the Large HadronĬollider’s main targets. Spotlight now,” Oliver Buchmueller, a senior physicist at ImperialĬollege London, told me. Matter), dark-chocolate chips (dark matter), and beetroot (darkĮnergy)-the universe’s mystery ingredient is “definitely in the Matter Day will be celebrated with Dark Matter Cake-baked with theĬosmically correct proportions of white-chocolate chips (visible Organization for Nuclear Research ( CERN), in Switzerland, where Dark WIMP, for weakly interacting massive particle-has proved an expensiveĪnd frustrating, if occasionally edifying, odyssey. Subatomic source of dark matter-the leading candidate is known as the Now thousands of physicists have joined the hunt. That an invisible incarnation of matter-a halo, as it’s occasionally Spiralling speeds, and given their visible mass, these stable structures Galaxies, Rubin and her collaborators observed that, given the galaxies’ Washington, D.C., confirmed Zwicky’s theory. Years later, Vera Rubin, of the Carnegie Institution for Science, in Wilson Observatory, in Los Angeles, as “spherical bastards,” since heįound them equally disagreeable from all sides. “It’s like a costumed trick-or-treater who rings the doorbell and thenĭashes away, and scientists are trying to unmask it!”ĭark matter was first theorized, in the nineteen-thirties, by Caltech’sįritz Zwicky, who reputedly referred to his colleagues at the Mount Play by the known rules of physics,” a promotional “Dark matter seems to ‘hide’ in plain sight and doesn’t This is why the Interactions Collaboration, a globalĬonsortium of particle-physics laboratories, has reimagined Halloween asĭark Matter Day. The rest-26.8 perĬent-consists of dark matter, a ghostly goo that is thought to hold theĬosmos together.
