LIGO is just completing it's second observation run, if they had 4 million
such runs you'
​d​
expect to see a jiggle as large

 October 12 2015

might see ​a noise jiggle as big as the
December 26 2015
​ event.  Actually it's even more unlikely than that because LIGO, being a
interferometer, can see more than just a jiggle, it can see an entire
waveform, and the waveform LIGO saw looks almost exactly like the waveform
Einstein predicted you'd see from 2 Black Holes spiraling into each other:

​But nothing is certain in life so maybe it's all just a huge coincidence,
but I wouldn't bet on it.

​I'll be mad if they just announce they're changing their logo or the
vending machines in the instillation's cafeteria,    ​
