It will be interesting to see just how fast these waves propogate. It may be faster than the speed of light.

The above experiment does not appear to be set up to record such a measurement, correct or not.

Waves of graviity have never been seen or measured. It may turn out that gravity doesn't have a speed.

It could be that gravity is instantaneous. In other words, if anothe star were to suddenly pop-up near the vicinity of our solar system, the gravitional effect would be felt instantly and not at the later time when light from the new star would have reached us.

Not if GR is correct (and we have every reason to believe that it is) - that these waves propagate at a limit of c is a consequence of general relativity.

There will be some serious explaining to do if this is not found to be the case...

It was observed a long time ago that there is an "orbital delay" among planets in our system.

We know the distance between the planets and the sun, very well. Light travels fast, but it is around an 8 minute delay (as I recall) between when it leaves the sun, and when it hits the earth. If gravity travelled faster than light, or slower than light, our earth orbit would seem faster or slower than the light "string" (that we see) attaching us to the sun. But the lag in our orbit exactly matches the 8 minute lag that light takes to hit us. So gravity is exactly the same speed as light. It's like we are being pulled around the sun buy a bent rope pulled by you when you whip a whip around your head.

Nope. If they exist, they will travel at the speed of light. Thank Einstein for the universal speed limit.
