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).
