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?
No. And, what do you mean by a closed universe? I wonder if you understand what that means? You clearly don't know what a standing wave is, so I have question if you grasp a more complicated concept such as a closed universe.
The biggest standing wave patterns seen by us are galaxy SPIRAL ARMS.
Utter nonsense. You seem to be so obsessed with standing waves that you see them everywhere.
barely moving but having the galaxies matter stars and all moving, ROTATING THROUGH them. (check it out) and similarly
Utter nonsense. The matter are what make up the spiral arms.
Connections. looking for corrections.
You're getting plenty of corrections but, sadly, haven't made any connections.
