A century ago gravitational wave detection was thought to be impossible. Fifty years ago it was the quest of a small bunch of intrepid physicists. They faced challenge after challenge, but their optimism persisted. They uncovered new physics, invented novel instruments and new techniques. New disciplines like quantum optomechanics, space laser communication, clock technology and airborne exploration technologies emerged from their efforts. Year after year they overcame setbacks, never imagining that it would take 40 years of struggle to achieve their quest.
When the direct detection of gravitational waves was finally achieved in 2015, it marked the beginning of a new era in astronomy. It brought with it surprises and opportunities, new horizons and new questions. Today, thousands of researchers all over the world work together, using increasingly sensitive detectors to explore the universe in ways that were once unimaginable.
This symposium marks fifty years since Australia became part of the international quest to detect gravitational waves. Celebrating the remarkable achievements of gravitational wave researchers, it aims to inspire the next generation of scientists, map the future, and identify opportunities. What are the greatest challenges, what might we discover and what is the future of physics?
The symposium is held in honour of David Blair, commemorating his 80th birthday and recognising his extraordinary 50 years of contributions to physics, physics education and public awareness of science.
