“Gravitational waves were detected on September 14, 2015 at 5:51 a.m. Eastern Daylight Time (09:51 UTC) by both of the twin Laser Interferometer Gravitational Observatory wave detectors.”—LIGO press release
when I entered your orbit
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
