Space politics, cosmological models and a proton mystery

31 May 2018

In the latest episode of Physics World Weekly, Hamish Johnston is in conversation with James Dacey about his recent trip to the April meeting of the American Physical Society (APS). Taking place this year in Columbus, Ohio, this annual conference focuses on just a few disciplines, including particle physics, nuclear physics and astrophysics. Johnston shares some of his highlights from the meeting, including clips from some of the scientists he met.

First up, Coral Wheeler from Caltech is talking about modelling the large-scale properties of the universe. She explains how her research could help to solve the “missing satellites problem” in the Lambda cold dark matter cosmological model. Next up, Laura Grego of the Union of Concerned Scientists explains why she is worried about the increasing militarization of space. Then finally, Randolph Pohl from Johannes Gutenberg University Mainz sheds light on the mystery surrounding the radius of the proton.
