May 10, 2023[Interview] Turning the Gravitational Wave Game To The Max
Gravitational waves can reveal things we would never detect otherwise. But different events require different sizes of detectors. In this interview, I'm talking with Waldemar Martens from ESA about a proposed LISAmax mission that will have 259 million kilometer arms and should be able to detect collisions of supermassive black holes.
