When Wanda Diáz-Merced lost her sight as a college student, she thought her dreams of becoming an astronomer were over — until she learned to listen to space instead.

Wanda is one of several pioneering scientists listening to space. For this episode, we also spoke to Robert Wilson, who used sound to help him discover the first direct evidence of the Big Bang, and Kim Arcand, who plays us what the center of the Milky Way sounds like.

This is the fourth episode in our of our new four-part series, ⁠⁠The Sound Barrier⁠⁠.

Guests: ⁠Wanda Diáz-Merced⁠, astronomer; ⁠Robert Wilson⁠, Nobel laureate and senior scientist at at the Harvard-Smithsonian Center for Astrophysics; ⁠Kim Arcand⁠, emerging tech lead at NASA's Chandra X-ray Observatory

A scientist asked people to sit in a silent room for 15 minutes. Almost half of them decided to give themselves a painful electric shock instead. What is it about our brains that makes our relationship with silence so strange? And should we learn how to listen to it?

This is the third episode of our new four-part series, ⁠The Sound Barrier⁠.
