According to Dr. Rory Smith from the ARC Centre of Excellence in Gravitational Wave Discovery at Monash University in Australia \u2014 it\u2019s likely there are another 2 million gravitational wave events from merging black holes, \u201ca pair of merging black holes every 200 seconds and a pair of merging neutron stars every 15 seconds\u201d that scientists are not picking up.<\/p>\n<p>Dr. Smith and his colleagues, also at Monash University, have developed a method to detect the presence of these weak or \u201cbackground\u201d events that to date have gone unnoticed, without having to detect each one individually. The method \u2014 which is currently being test driven by the LIGO community \u2014 \u201cmeans that we may be able to look more than 8 billion light-years further than we are currently observing,\u201d Dr. Smith said.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Every year, 2 million black hole mergers are missed \u2014 Australian scientists work out how to detect them, revealing a lost 8 billion light-years of Universe evolution.
