New Scientist reporter Abigail Beall spotlights how MIT researchers have listened to sound waves traveling through a "perfect" fluid, which could shed light on the resonant frequencies within a neutron star. “The quality of the resonances tells me about the fluid’s viscosity, or sound diffusivity,” says Prof. Martin Zwierlein. “If a fluid has low viscosity, it can build up a very strong sound wave and be very loud, if hit at just the right frequency. If it’s a very viscous fluid, then it doesn’t have any good resonances.”
