Scientists have made a third detection of gravitational waves, again caused by the merger of two black holes. But they think there’s something different about the black holes in this case.

These ripples in the very fabric of the universe were hypothesized by Einstein a century ago. Now scientists have detected them for the third time in a year and a half – ushering in a new era in astrophysics.
The OzGRav Centre of Excellence for Gravitational Wave Discovery will enable Australian researchers to be at the forefront of gravitational wave astronomy.
The observation of gravitational waves from a second black hole merger implies there are many more black holes in the universe than scientists had previously anticipated.
Scientists being wrong is not a bug or a glitch – it’s a feature of science and mistakes can actually lead to new, deeper discoveries.
Scientific advances – including the recent discovery of gravitational waves – force us to deal with numbers so extreme they’re virtually inconceivable.
The hunt to find the source of the gravitational waves detected by LIGO on the sky is only just starting.
The discovery of gravitational waves has ushered in a new era in astronomy and physics. Where will the next big discovery be made? There’s no reason for it not to be Africa.
The discovery of gravitational waves involved a team of more than 1,000 scientists from across the globe, including Australia. So how does such an international collaboration work?
It’s taken centuries for our understanding of gravity to evolve to where it is today, culminating in the discovery of gravitational waves, as predicted by Albert Einstein a century ago.
Sometimes big research news bypasses the usual scientific publishing process. Here’s why that’s not good for scientists or the public.
Here’s a LIGO insider’s description of how he got the news of a phenomenon that had first been theorized 100 years ago.
It is the physics discovery of the century – even bigger than the Higgs Boson. Here’s how it happened and what it means, by a key member of one of the lead teams
