Boffins' gravitational wave detection hat trick blows open astronomy

"Their velocity is constant. So if the distance changes, the frequency of the light must change to keep the speed constant"

Bit what is distance? If you had a ruler it would be warped along with any other matter so you wouldn't see a change in distance.

"so much space has been "created" in the intervening years that they're now microwaves."

But the expansion of the universe "creates" extra space like filling a bathtub with water. Whereas gravity waves surely are more like waves on the water already in the tub.
