Belczynski agrees, saying that if mergers of black hole - neutron star binaries prove to be common, they must arise from systems that don't resemble Cygnus X-1.

Thus, Belczynski's team concludes that if Cygnus X-1 is representative of future black hole - neutron star binaries, observers seeking to detect gravitational waves should not expect to see them from mergers of such systems.

But how did these two black holes end up in a binary system?

In such a cluster, massive stars would sink towards the centre and, through complex interactions with lighter stars, form binary systems, possibly long after their transformation into black holes.

The LIGO team's analysis suggests these spins were misaligned, indicating that the pair of black holes might not always have been together in a tight binary system but, rather, randomly came together over time.

«Many sources that emit transient X-ray flares, such as black hole binary star systems, also have associated radio emission.

Several of them are X-ray binary systems that contain a neutron star or black hole orbiting a Sun - like star.

The existence of black holes is now considered well established, both on a stellar scale, such as exists in the binary system Cygnus X-1, and on a scale of millions of solar masses at the centres of some galaxies.

Since most galaxies in the universe are believed to harbor one supermassive black hole at their center, the presence of a binary system is conclusive evidence of a galactic merger.

For example, if a black hole is a member of a binary star system, matter flowing into it from its companion becomes intensely heated and then radiates X-rays copiously before entering the event horizon of the black hole and disappearing forever.
