In February, scientists from LIGO (Laser Interferometer Gravitational-wave Observatory) detected the tiny ripples in the fabric of space-time caused by the collision of two unbelievably massive black holes, more than a billion years ago.
Albert Einstein's theory of relativity predicted that gravity would have infinitesimally small waves but he thought them so tiny, they'd never be detected. However, the sensitivity of LIGO, whose mirrors were built in Sydney by CSIRO scientists, allowed for the detection of the gravitational remnant of that collision passing by Earth in two-tenths of a second.
The discovery is opening up a new view on the universe. Up until now we have only been able to see the stars in the electromagnetic spectrum of lightwaves. We will now be able to view the universe using gravitational waves.
