Why are the propagation of gravitational waves limited to c?

They aren't movement *in* spacetime, they're movement *of* spacetime, no?.

If spacetime expanded, at least initially, much faster than c, doesn't that suggest that spacetime itself can move faster than c? (Is "move" even the right word?)

  - It certainly can be no greater than c - RL - 8/27/2017 11:09:04 PM

        Johannes, you're as bad as Trump when he deliberately left out "on many sides..." - mcfly - 8/29/2017 3:15:29 PM
        
        Trump ?? - johannes - 8/30/2017 2:30:11 AM
        
        Yes, RL is doing a good job - mcfly - 8/30/2017 5:27:55 AM
        
        I do not understand how you can..... - johannes - 8/30/2017 8:42:25 PM
        
        I refer you to RL's post, "Three times in this thread..." - mcfly - 8/31/2017 11:09:32 AM
