*If*.  But they do _not_, so there is no problem.

Instead, picture the two black holes spiraling in on each other, that caused 
GW150914, as a pair of black swans circling around each other near the 
center of a pond, and the gravitational waves of GW150914 as the ripples 
that are produced on the water surface by the birds’ motion.

You would not say that the water ripples escaped the swans, would you?

Now picture the pond to be circular with a radius of one billion light-years 
(short scale; the approximate distance those two black holes were away), and 
yourself to be an mosquito larva swimming near the banks of the pond.  Then 
you get a good idea as to why the LIGO arms have to be that long, why 
building this was so expensive, and why it took months of checking and 
double-cecking for the LIGO Scientific Collaboration to be certain that they 
had detected gravitational waves.
