This is amazingly great news, in particular how Einstein again and again gets proven right. I wonder what other discoveries we will make in the future by detecting gravitational waves.

That gravity is now confirmed to travel at the speed of light is insightful. The speed of light (in a vacuum) seems to be one of those fundamental attributes of the universe and not simply the speed at which light travels.
The speed of light - its not just a good idea, its the law.
