Astronomers have long been able to watch the universe's blockbuster special effects unfold in dazzling 3D Technicolor. But until now, it's been like watching a silent movie. Today that all changes. Scientists announced this morning that they have for the first time ever detected both light and gravitational waves from a massive explosion in space caused by the collision of two super-dense neutron stars. On today's show, we talk to astrophysicist Pawan Kumar about what this breakthrough means for his field.
