I actually was sort of curious as to the opposite. What does it mean if gravitational waves (that we can detect) are extremely common and become fairly easy to detect with future technology given todays news?
The article says many expected LIGO to take much longer but it found it rather earlier equating it to beginners luck (I know the article is written for the layperson but it leaves much to be desired with that phrase).
You never know we could have telescopes that use Gravitational waves instead of light.
It would mean that there are a lot more black holes in our local group, which could be a little concerning.
But yeah that's actually an application of LIGO once it's sensitive enough, because gravitational waves travel through just about anything including those annoying dust clouds :)
