Melbourne: Scientists have developed a new technology that can listen to background humming of deep space and unveil thousands of hidden black hole collisions missed by gravitational-wave detectors.
Deep space is not as silent as we have been led to believe. Every few minutes a pair of black holes smash into each other. These cataclysms release ripples in the fabric of spacetime known as gravitational waves.
The gravitational waves from black hole mergers imprint a distinctive whooping sound in the data collected by gravitational-wave detectors.
The new technique developed by researchers from Monash University in Australia is expected to reveal the presence of thousands of previously hidden black holes by teasing out their faint whoops from a sea of static.
