    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 in […]

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 a […]
