OzGrav, short for the ARC Centre of Excellence for Gravitational Wave Discovery, is an Australian research center dedicated to the study of gravitational waves, which are ripples in spacetime caused by some of the universe’s most violent and energetic processes. Established in 2017, OzGrav’s main focus is on advancing our understanding of gravitational waves through international collaborations, leveraging facilities like the Advanced LIGO (Laser Interferometer Gravitational-Wave Observatory). The center engages in a broad range of activities, including developing new technologies to improve gravitational wave detectors, exploring the astrophysical implications of gravitational wave observations, and educating the next generation of scientists in this emerging field. OzGrav aims to harness these cosmic phenomena to unlock new knowledge about black holes, neutron stars, and the fundamental laws of physics.
Since 2015, the LIGO-Virgo-KAGRA Collaboration has detected about 85 pairs of black holes crashing into each other. We now know that Einstein was right: gravitational…
