Space expansion, gravity waves, warp

[Edi]

If gravity waves are supposed to propagate at c, how could the theoretical warp drive wave propagate at greater than c values?
I have heard and red and understand that space itself can expand (and warp? ) faster than c and, in fact, that will happen in the future when space in between galaxy's will be expanding faster than c and the galaxy's will disappear from our observable universe, but, in that case, why would gravity waves only propagate at c ?

What "theoretical warp drive wave"? Can you give us a reference or link?

The Star Trek warp drive, you know. Real world reserch is even made in the field. http://www.extremetech.com/extreme/...h-prepares-to-create-a-warp-bubble-in-the-lab

Sorry, but Star Trek is fiction.
