Australian scientists have developed a new methodology that they say will allow astrophysicists to hear the noise of black holes colliding with each other in space and time.
The Melbourne advance researchers promise to shed new light on the early universe.
"Not only are we seeing the black holes in our immediate neighborhood, but we are seeing black holes from the early ages of the universe when the stars were just being made," Monash Dr. Eric Thrane of the University said at 7.30 .
Every three minutes, somewhere in the universe, two black holes are colliding.
Because the gravity of these giants is so immense, when they come together they shake the fabric of space and time, sending gravitational waves through the cosmos.

Physicists first detected this gravitational wave radiation in 2016, using the LIGO instrument in the United States, and was awarded a Nobel Prize for the discovery.
The Astrophysicists team based in Melbourne have advanced even further in this advance, developing new techniques that they say will allow them to hear the general background noise of the black holes that merge throughout the cosmos.
Being able to hear the sound of so many smaller black holes ever further from the Earth will allow scientists to explore more deeply in the history of our universe.
7.30 asked three astrophysicists to harmonize their interpretation of sound.

Astrophysicist Silvia Biscoveanu of MIT in the United States is in Australia working with Melbourne researchers.
"Gravitational waves are not sound waves, but we can represent them as sounds, so we can hear how black holes sound," he said at 7.30.
The widespread opinion was that the LIGO detector would not be sensitive enough to hear these mergers, but Australian researchers believe that taking advantage of the power of Swinburne University's new mbadive supercomputer will allow them to listen.
His new technique is to examine the huge amounts of data that the detectors have collected, unraveling the background noise. 19659005] "It gives us an idea of the universe in its most extreme form," said Matthew Bailes, director of the OzGrav Center of Excellence for Gravitational Wave Discovery.
"It's when you've somehow established the laws of p hysteria to 'stun', and to a physicist who's an exciting place to probe."
