That's why it was a surprise when physicists with the Laser Interferometer Gravitational - Wave Observatory (LIGO) announced in February 2016 that they had detected ripples in space from the violent merger of two black holes 29 and 36 times as massive as our sun.
For this study, Koushiappas and Loeb calculated the redshift at which black hole mergers should no longer be detected assuming only stellar origin.
Physicists concluded that the first detected gravitational waves, in September 2015, were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole.

MAKING WAVES The first gravitational wave signal detected by LIGO came from the merger of two black holes spiraling inward, as depicted in this numerical simulation.
But only some of the most massive astrophysical events, such mergers of black holes and neutron stars, can produce gravitational waves strong enough to be detected on earth.
When Eleonora Troja got the LIGO notification on 17 August that new gravitational waves had been detected, she dismissed it at first, assuming it was just another black - hole merger, she recalls.
One of the most important scientific consequences of detecting a black - hole merger would be confirmation that black holes really do exist — at least as the perfectly round objects made of pure, empty, warped space - time that are predicted by general relativity.
This suggests LIGO — which is in the midst of upgrades to boost its sensitivity and planning for a new station in India — could eventually be detecting the chirps from black hole mergers at a rate of anywhere between once per day to once per week.
In a new study, the scientists show their theoretical predictions last year were correct: The historic merger of two massive black holes detected Sept. 14, 2015, could easily have been formed through dynamic interactions in the star - dense core of an old globular cluster.
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.
(These are different gravitational waves from the ones detected this year by the Laser Interferometer Gravitational - Wave Observatory, which originated from the mergers of black holes).

Judy Racusin, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, said during today's press conference that the Fermi team is «cautiously saying [the gamma - ray signal] is potentially associated with the black hole merger» detected by LIGO.
More - stringent tests will be possible if and when LIGO detects black - hole mergers that are larger than this one, or that occur closer to Earth than the Event's estimated distance of 1.3 billion light years, and thus give «louder» waves that stay above the noise for longer.
The LIGO press release mentions an estimation of black hole merger rates — «about one every 10 years in a volume a trillion times the size of the Milky Way Galaxy» — based on how many signals it's detected so far.

The detection came in the early morning hours of January 4, 2017, LIGO researchers said in a press release, and the coalescing black holes were approximately three billion light years away from Earth when the collided, making this the most distant merger of its kind detected to date.

An interesting theory from early 2015, before the first black hole merger signal had been detected, drafts a compelling scenario, formulated by Madrid professor Juan Garcia - Bellido and postdoc Sebastien Clesse from RWTH Aachen University: maybe the universe is crowded with black holes of various sizes, remnants of large density fluctuations during the so - called inflation phase of the Big Bang.
