Neat.

I believe that the researchers will be exploring all possibilities of exotic variants in decades to come in 'gravitational astronomy'. Unlike light they don't seem to reflect or lense but travel right through things. If the ones observed from the binary blackhole merger took one billion years to get to us, where are all the others, there should be massive numbers of waves moving through space/time in all directions.
I can just hear people ringing work and using a gravitational wave passing through them to excuse all sorts of things - the ulimate excuse.
