You probably haven't noticed, but the universe is quite a big place.  ;)

Most mergers are far distant, from the early universe creation.
Search for 100,000 black hole mergers, for more info.

BillK, it's a mind-blower.  LIGO and Virgo have revolutionized my picture of the early universe more than the first good images from Hubble.  These instruments look farther back in time.

My view of inflation cannot explain how the early universe was so anisoptropic.  It should have been too uniform during the inflation to have all these mergers.  I have been surprised twice: the COBE results showed us that the universe is more homogeneous than we expected, now LIGO/Virgo is showing us that it is less homogeneous than we expected.
