This radio broadcast discusses some exciting new experiments in gravity, and what might be learned from them. The show explains three experiments that test predictions of the General Theory of Relativity (GR): the LIGO (Laser Interferometer Gravitational Wave Observatory), Gravity Probe B (GPB), and the discovery of a binary neutron star system, which indirectly proved the existence of gravitational radiation. There is discussion about how the most important advance by LIGO may be our ability to use gravity waves to study the objects in the universe that emit them; how there are intellectual problems with both GR and quantum theory; and how GR may possibly need to be modified either in the quantum regime or due to unexpected results in the experiments discussed. The broadcast is 49 minutes in length.
