If the universe is and was closed at the time of the gravity wave event, like violin is a closed entity, could they not be construed to be standing wave batterns too? and:
The biggest standing wave patterns seen by us are galaxy SPIRAL ARMS. barely moving but having the galaxies matter stars and all moving, ROTATING THROUGH them. (check it out) and similarly
the tidal bulges are barely moving, in a monthlyslow swing,
and matter, water & crust material is MOVING THROUGH them as the earth ROTATES.
Connections. looking for
corrections.
