In 1916, using his brand new theory of gravity - General Relativity, Einstein found that, like electromagnetic waves, gravitational waves exist in his theory, although extremely weak. Precisely 100 years later, these ripples of spacetime were detected by two detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO), one is located in Livingston, Louisiana, and the other in Hanford, Washington, USA.
The event was recorded on September 14, 2015 at 5:51 a.m. Eastern Daylight Time (09:51 UTC). This represents one of the major achievements in the history of Einstein's theory, and opens an unprecedented new window onto the cosmos.
In this talk, I shall give a basic review on gravitational waves in Einstein's theory, explain the challenges one has to face for their detections, and introduce the most likely astrophysical sources to produce strong enough signals for us to observe on Earth. The discovery is the culmination of decades of instrument research and development, through a world-wide effort of thousands of researchers and organizations. More excitingly, it marks the beginning of a new era of gravitational wave astronomy – the possibilities for discovery are as rich and boundless as they have been with light-based astronomy. |
