Precision measurement from Einstein – and for Einstein.

Speaker: Prof. David Shoemaker, Massachusetts Institute of Technology, US
Abstract: The US Laser Interferometer Gravitational-wave Observatory (LIGO) recently made the first detections of gravitational waves from black holes. LIGO consists of two observatory sites, in Washington and Louisiana, USA, managed by the California and Massachusetts Institutes of Technology. The LIGO Laboratory has developed sensitive laser interferometers to detect the strain in space-time due to gravitational waves, predicted by Einstein as a consequence of general relativity. The instrument science behind the detectors is challenging because fundamental physics limits must be addressed — ones that Einstein helped us understand. The promise of gravitational wave observations is a better understanding of Einstein’s general relativity, and otherwise impossible insights into exotic astrophysics.
