Does the propagation of a gravity wave through a massive object encounter resistance from the mass of said object?

I'm wondering if gravity waves propagating through empty space and gravity waves propagating through something massive like a star carry on at the same speed.

We have never observed gravity to slow down or gravitational waves to scatter from matter interactions. Theory states that at least the former does not occur, but we haven't really had the facilities to perform the necessary experiments to verify this to any certainty. The fact that our galaxy is very dense in the center, so that light is occluded, yet the gravity of distant objects appears completely unimpeded, *suggests* that this may be right.
