    Dark Matter Gets a Reprieve in New Analysis

    Reprinted with permission from Quanta Magazine’s Abstractions blog. The galactic center shines too brightly, like the glow of a metropolis at night where maps show only a town. To mend their cosmic cartography, astrophysicists have spent years debating what could be powering this excess of energetic light. In 2015 the arguments appeared to swing decisively […]

    7 Major Experiments That Still Haven’t Found What They’re Looking For

    Being an experimental scientist can sometimes seem like a thankless task. You may be used to reading headlines about experiments that end up making great discoveries, but less is heard about the (often heroic) efforts of experimentalists that have yet to detect or observe what they set out to. Some of these efforts have spanned […]

    Dark Matter May Be Trapped in All the Black Holes

    This isn’t the first time scientists have suggested black holes might be dark matter, but we thought the possibility had been decisively ruled out. The resurrection of the idea is but one example of the fertile creativity that follows a new discovery.Photograph by NASA Goddard Space Flight Center / Flickr When, on February the 11th, […]

    Why We Love to Anthropomorphize Physics

    Family Physics” may be the best episode of Public Radio’s long running show, This American Life. Its premise was simple. Import key concepts from the realms of quantum mechanics and cosmology and use them to illuminate the everyday world of parents, kids, and their interactions. Introducing the show, however, host Ira Glass was quick to […]

    The Best Evidence for Dark Matter & the Uncertainty Therein

      If I told you that I was 99.81 percent certain I had made a big discovery, you might suggest it was time to break out the champagne. If I said the discovery resolved one of the biggest outstanding problems in science and would probably let me punch a ticket to Stockholm to pick up […]
