“It’s likely there are another two million gravitational wave events from merging black holes –a pair of merging black holes every 200 seconds and a pair of merging neutron stars every 15 seconds– that scientists are not picking up,” says Rory Smith at OzGrav (ARC Center of Excellence in Gravitational Wave Discovery), about a new method of detection being tested that means that “we may be able to look more than 8 billion light years further than we are currently observing. This will give us a snapshot of what the early universe looked like while providing insights into the evolution of the universe,” adds Smith.
