September NSA Club Meeting

  • Schaumburg Township District Libary 130 South Roselle Road Schaumburg, IL, 60193 United States (map)

Shane Larson of Northwestern University joins us for a presentation on gravitational waves.  Up to now, virtually everything we know about the universe has been discovered from the study of photons. However, advanced technology now enables us to study ripples in the fabric of spacetime itself. Over the past two years the first gravitational waves have been detected.  They reveal black holes dancing a death spiral billions of light-years distant and neutron stars ripping themselves apart in a titanic burst of light and gravitational energy. Shane's program will explore what gravitational waves are, how we measure them, and what we are learning from them.
