when I entered your orbitGravitational Waves_02
and you swept into mine
I gave a gravitational wave
which you returned and I received
without the help of lasers

now a billion years have passed
and here we are

black holes have come and gone
whose waves are rippling
through the universe still,
but give no light to gazers
