Gravitational Waves: What Did They Reveal?

Earlier this week, gravitational waves were detected for a fourth time by observatories on opposite sides of the globe. This discovery comes a few weeks after The Advanced Virgo observatory in Italy teamed up with LIGO (Laser Interferometer Gravitational-Wave Observatory) from the United States to observe our solar system. However the question lies, what did these waves reveal and how does this change what we know about space?  The Daily was joined on the line by Professor Susan Scott, from Department of Quantum Science Physics Education Centre at Australian National University.
