Riding the dark wave

The 2020 Prime Minister’s Prize for Science has been awarded to two ANU physicists and two scientists from other institutions for their ground-breaking work to uncover the darkest parts of the Universe.
Will Wright reports.

Following an epic 100-year quest set by Albert Einstein, gravitational waves were detected on Earth on 14 September 2015. The signal came from the collision of two massive black holes 1.3 billion years ago, more than 10,000 million, trillion kilometres from Earth. That’s almost a 10th of the way back to the beginning of the known Universe.
