The waves are called gravitational waves and hey are real! Astrophysicist Dr. Wanda Díaz Merced tells the story of what happened when they hit Earth in 2015, and how scientists came to learn to use senses beyond eyesight to detect the waves. We also learn from Dr. Stavros Katsanevas about the building of a giant gravitational wave catcher called “The Interferometer.” This episode also explores how to persist in the face of doubt as we learn Wanda's tale of going blind and learning how to listen to the stars.

The Shovels: Dig Deeper
For each episode of Terrestrials, we provide a selection of activity sheets, drawing prompts, musical lessons and more. We call them “shovels” because we hope they will help you (and your friends, family, students, neighbors, etc) dig more deeply into the world! You can do them at home, in the classroom, outside, or in the privacy of your own mind. We hope you enjoy!
