In addition to the exhibit, guests listened to in-depth discussions with black hole experts from the CGCA at UWM. There were six 30 minute lectures covering five different topics and geared toward a general audiences: Dr. Patrick Brady explained how the idea of dark stars gave way to the current idea of a black hole as a place in spacetime from which nothing can escape, not even light. The discussion ended with tantalizing hints of how important black holes are in understanding the universe. Dr. David Kaplan described the intriguing observations of the first black hole candidates and how they formed in the aftermath of a massive stars' explosion. Dr. Jolien Creighton explained how black holes evaporate according Stephen Hawking’s most celebrated contribution to black hole physics. Dr. Dawn Erb explained her studies of the relationship between the formation of galaxies and the supermassive black holes at their center. Dr. Xavier Siemens will described the innovative ways we have to look for the merger of supermassive black holes.
The exhibit, Astronomy's New Messenger: Listening to the Universe with Gravitational Waves, gave guests the opportunity to learn about black holes and the exciting work that is being done by the Laser Interferometer Gravitational-Wave Observatory (LIGO). This traveling exhibit was developed with National Science Foundation funding.
