Gravitational waves: they are the echoes of the most calamitous events in the Universe, like the collisions of black holes, yet it has taken us nearly 100 years to finally be able to hear them. The detection of gravitational waves has been the end of a theoretical quest to confirm Einstein's predictions, and a technical quest to hear their tiny echoes when they finally meet our detectors. But this is also just the beginning of a new wave of gravitational astronomy, opening the possibility of deeper understanding of our Universe.
This collection of articles and videos tells you all you need to know about gravitational waves and their discovery. They are based on an interview with Gabriela Gonzáles, Professor of Physics at Louisiana State University and former spokesperson of the LIGO Scientific Collaboration, and a lecture given by Kip Thorne, a pioneer in all things gravitational waves. We also bring you a relevant article from the FQXi Community website.
These articles and videos are part of our Stuff happens: The physics of events project.
