First Detection of Gravitational Waves

ligoInterview with LIGO Scientist Dr. Matt Evans (6:22): The recent big news in physics was the announcement of the first direct detection of gravitational waves.  The detection was made by the LIGO project, which stands for “Laser Interferometer Gravitational-Wave Observatory”.  Reports have said that this is a confirmation of general relativity and a new way to view the universe.  To help us understand that, and why this is such a significant achievement, we have on the phone Dr. Matthew Evans, an Assistant Professor of Physics at MIT.  Dr. Evans is a member of the LIGO Scientific Collaboration and the chair of the Advanced Interferometer Configurations working group.  His research focus is on gravitational wave detector instrumentation, and the fundamental sensitivity of gravitational wave detectors.

And here you can see the signal and hear the “chirp” of a graviational wave!
