Big bang retold: The weird twists in the story of the universe’s birth

    From New Scientist, Dec. 11, 2019: Fermilab scientist Dan Hooper is quoted in this article on what scientists mean when they talk about the Big Bang. The best evidence for the big bang is all around us in the cosmic microwave background, the radiation released once the universe had cooled sufficiently for atoms to form, when it was about 380,000 years old. And that is the point: everywhere in today’s universe was where the big bang was.

    High-resolution MicroBooNE detector provides new details in neutrino-argon interaction measurement

    Scientists on Fermilab’s MicroBooNE experiment have measured neutrino interactions on argon with unprecedented statistics and precision using data on the resultant muons — in particular, the muon’s momentum and angle. The experiment features the first liquid-argon time projection chamber with the resolution and statistics to carry out such a measurement. Researchers will use the result to improve simulations of neutrino interactions. These improvements are important for neutrino experiments in general, including the Short-Baseline Neutrino program experiments and the international Deep Underground Neutrino Experiment, both hosted by Fermilab.

    Shaping the technology transforming our society

    In November, the Chicago Quantum Exchange held a workshop about ethics and societal impacts of artificial intelligence and quantum computing technologies. Participants from a wide variety of academic backgrounds, from physicists to sociologists, discussed the implications of technology on society and vice versa and identified critical steps scientists need to take so technology is developed and implemented ethically and responsibly.

    Physics books of 2019

    The year 2019 was a banner one for Albert Einstein: It included the first image of a black hole and the 100th anniversary of the 1919 solar eclipse expeditions that validated his theory of general relativity. Learn more about both, plus topics such as quantum theory, the Hubble Space Telescope, and the science (and fiction) of “Game of Thrones” in Symmetry writer Mike Perricone’s annual list of new popular physics books.

    Will we ever find dark matter in the universe?

      From Time, Dec. 6, 2019: Fermilab scientist Dan Hooper summarizes the current state of the search for dark matter. Scientists can say with great confidence that we understand how and why our universe evolved over the vast majority of its history. From this perspective, the universe looks more comprehensible than ever before. And yet, not all is understood.
