Fifty years ago, Fermilab turned to bubbles

    From Science News, Aug. 8, 2019: It’s a news flashback. Science News excerpts a bit on the Fermilab Bubble Chamber from their August 16, 1969, issue. “Use by visitors is expected to be especially large at the National Accelerator Laboratory now under construction at Batavia, Ill…. NAL staff and consultants agree that the laboratory will need a large bubble chamber, and it now plans to build one in collaboration with Brookhaven National Laboratory.”

    Resurrected detector will hunt for some of the strangest particles in the universe

      From Science, Aug. 8, 2019: Fermilab physicists are resurrecting a massive particle detector by lowering it into a tomblike pit and embalming it with a chilly fluid. In August, workers eased two gleaming silver tanks bigger than shipping containers, the two halves of the detector, into a concrete-lined hole. Hauled from Europe two years ago, ICARUS will soon start a second life seeking perhaps the strangest particles physicists have dreamed up, oddballs called sterile neutrinos.

      Breakthrough Prize awarded to architects of supergravity

      Our world is governed by general relativity, which sees gravity as the effects of massive objects warping space-time. The world of particle physics, on the other hand, envisions all forces as mediated by force-carrying particles — and ignores gravity entirely. This year’s Breakthrough Prize in Fundamental Physics was awarded to three theorists who proposed a way to marry these contradictory descriptions: with a theory called “supergravity.”

      Dark matter has never killed anyone, and scientists want to know why

        From Popular Science, July 29, 2019: “Death by Dark Matter” is not the name of your new favorite metal band; it’s the literal title of a new study by a trio of American of physicists. Fermilab science Dan Hooper is quoted in this article on their paper, which explores what the hypothetical consequences might be on the human population if a certain candidate of dark matter turned out to be true.

        Gravity’s waterfall

        In recent years, scientists have found ways to study black holes, listening to the gravitational waves they unleash when they collide and even creating an image of one by combining information from radio telescopes around the world. But our knowledge of black holes remains limited. So scientists are figuring out how to make do with substitutes — analogs to black holes that may hold answers to mysteries about gravity and quantum mechanics.

        Innovation: Subatomic music

          From SDPB Radio’s “In the Moment: Innovation,” July 26, 2019: In this 7-minute radio piece, Fermilab 2018 artist-in-residence Adam Nadel talks about a musical composition he wrote based on neutrino experiment data. When neutrinos interact with other particles inside an argon detector, those interactions are recorded by thousands of thin wires. Nadel transcribed the wire over time onto a musical score.
