David G. Blair (born 1946) is an Australian physicist and professor at the University of Western Australia and Director of the Australian International Gravitational Research Centre. Blair works on methods for the detection of gravitational waves. [1] He developed the niobium bar gravitational wave detector NIOBE, [2] which achieved the lowest ...
David Blair is a gravitational wave physicist who has spent more than 4 decades developing methods for the detection of gravitational waves. In 1984 he invented the sapphire clock. During the 1990s he set up the Gingin gravitational wave research centre. The Gingin centre researched techniques which were implemented in the LIGO gravitational ...

The first detection occurred 99 years after Albert Einstein predicted the existence of gravitational waves. Two Advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO) laser interferometers simultaneously detected a signal characteristic of a pair of black holes – 29 and 36 times the mass of the sun – merging into one. Gravitational wa...
The ringing at the end of the waveform is the dying vibration of the new formed black hole, which is 62 times the mass of the sun. The estimated distance of the event was more than 1 billion light years. The surface area of the new black holeis four times the area of Tasmania. The total power output in gravitational waves over the event duration wa...
The first detection turns hypotheticals into observational reality. Suddenly the idea of space-time as a medium able to ripple and curve is inescapable. Suddenly we know that the black holes predicted by Einstein’s theory are really out there drifting through the universe. The first detection of gravitational waves confirms the physics of the inter...
Apr 22, 2016 · David chose gravitational waves and whilst it didn’t take the predicted year or two to discover, he was never deterred by critics. Sustained by optimism, 40 years later the dream was realised. Professor Blair and his team started building a detector consisting of a huge bar of niobium at UWA in 1976 in the hope of detecting these waves.

Metrics. Gravitational radiation has not been positively detected. Over the past two decades an army of extremely sensitive detectors has been built up, so that today its detection appears inevitable. In the opening chapters of this 1991 book David Blair introduces the concepts of gravitational waves within the context of general relativity.
