Four questions for Roger Blandford on new evidence of gravitational waves

Gravitational Waves
An event that blew away the astronomical world
Oct 15, 2017
On the morn of Thursday, August 17, 2017 the LIGO-Virgo Collaboration (LVC) gravitational wave detectors saw a binary neutron star (BNS) collision in gravitational waves—and kind of blew up the astronomical world who was in on it, that day.
Why do I say this, after the announcement of the discovery of gravitational waves from a binary black hole (BBH) coalescence already made such major "ripples" amongst those who pay attention to things astronomical, just 1 1/2 years ago? (Resulting in the Nobel Prize being awarded for this, on October 3, 2017).

The first direct detection in 2015 of a gravitational wave event (GW) by the recently upgraded Laser Interferometer Gravitational-Wave Observatory, known as Advanced LIGO, ushered in with a mighty bang a completely new era in astronomy. The first science run with the Advanced LIGO detector started in September 2015, and two high-significance events (GW150914 and GW151226) and one sub-threshold event (LVT151012) were reported. These three events were compatible with signals expected from the mergers of two black holes.
