Ok, couple of things:

Gravity waves: physicists are spending large amounts of money on gravity infereometers to detect the presence of gravity waves. No-one has done so yet, but there is hope. Gravity wave detection is extremely difficult (if they even exist), because it is very hard to account for all disturbances possible. However, it is known that gravity, like other forces, travels at c (speed of light in a vacuum)

Wasn't there observational (non-experimental) proof of gravity waves from rotating pulsars? I think it resulted in 1993 Physics Nobel?
