Making (Gravitational) Waves

Nearly 100 years after Einstein predicted the existence of gravitational waves — huge undulations in the fabric of space-time itself — in 2015, detectors here on Earth finally picked up the signal of these massive disturbances.

Dr. Michelle Thaller pulls apart the power and mystery of gravitational waves, and talks with Dr. Janna Levin, theoretical astrophysicist and author of the book, Black Hole Blues and Other Songs From Outer Space.

Image caption: The LISA Pathfinder Mission paves the way for our first space-based gravitational wave detector. Having these detectors in space, instead of on Earth will make them much more sensitive and have less interference from other Earth-based noises, in our search for more clarity on gravitational waves.
