Listening to the Universe with Gravitational Waves

Listening to the Universe with Gravitational Waves takes a topic that sounds forbidding and makes it approachable: astrophysicist Shanika Galaudage from the Adler Planetarium and Northwestern University explains what gravitational waves actually are, how detectors catch them, and what they reveal about black holes and neutron star collisions. The talk runs for an hour on Thursday evening, October 15, starting at 6 PM, at Sulzer Regional Library. It is part of this year's One Book, One Chicago season tied to Samantha Harvey's *Orbital*. Registration is open, and accessibility requests should be made at least 14 business days in advance.
