Predicted by Einstein’s general theory of relativity but yet to be directly observed, gravitational waves are ripples in space–time generated by accelerating massive objects. Other scientists caution that the astrophysical objects thought to emit such radiation may do so very weakly or might not actually exist. The detector is designed to register very high frequency gravitational waves via the exceptionally weak vibrations they would induce. Webinars Tune into online presentations that allow expert speakers to explain novel tools and applicationsĪ coin-sized detector might observe gravitational waves before the giant LIGO interferometers, according to two Australian physicists who have built the device.Video Watch our specially filmed videos to get a different slant on the latest science.Podcasts Our regular conversations with inspiring figures from the scientific community.Audio and video Explore the sights and sounds of the scientific world.
