Gravitational Waves: Slowed by Media?

[Khashishi]

Are gravitational waves slowed by media? Electromagnetic waves are slowed when traveling through dielectric media because the electric field polarizes the media. If a gravitational wave travels through matter, then the matter shifts around, much like the dielectric, right?

Technically yes, but that effect will be negligible due to the extremely weak gravitational interaction

Sorry to nitpick, but we are talking about Gravitational waves. Gravity waves are like water waves. http://en.wikipedia.org/wiki/Gravity_wave

oops. I do mean gravitational.
