In this episode of Physics World Weekly, James Dacey is in conversation with cosmologist Jo Dunkley about her new book, Our Universe: an Astronomer’s Guide. Written for a general audience, the book takes readers on a voyage through some of the biggest questions in modern cosmology. Along the way we encounter the fabric of space–time, physics beyond the Standard Model of particle physics, and the search for life beyond our Earth. Jo also speaks about her own research, testing astronomical models with data from the Atacama Cosmology Telescope in Chile.
Later in the podcast, a selection of Physics World journalists discuss some of the week’s most interesting developments. Hamish Johnston and Michael Banks discuss the ongoing debate among the physics community over the plans to build a next generation particle accelerator. The debate has flared up recently with theoretical physicist Sabine Hossenfelder’s opinion piece in the New York Times, which questioned CERN’s plans to build a more powerful – and significantly more expensive – successor to the Large Hadron Collider (LHC).
Matin Durrani and Sarah Tesh also join the podcast to talk about the February 2019 issue of Physics World. They also speak about the impressive winning designs for the festive jumper competition that we launched just before Christmas.
