It would be impossible to meaure right now, and actually, the mass, whatever mass that would be, would be felt slowly, as it got closer, it's gravitational attraction would get stronger, the larger the object, the stronger the gravity well. and again, as it got closer, it's graitational effects would get stronger, but at this pint it is IMPOSSIBLE to measure such a thing.

Until it is technically possible to do that, then we won't really know, but can take some good guesses.

As Einstein thought, C is the limit, so I would have to assume, since he was right about a LOT of things, that Gravity would travel at C as well.

But again, it is impossible to measure, therefore we will not know until the technolgy is available.

"But again, it is impossible to measure, therefore we will not know until the technolgy is available."

Really? You mean we can't measure something that travels so fast as Gravity? That we can't see the impact of a Gravitational disturbance on our tides or our instruments? That we can't observe the plane in which each planet orbits?

"As Einstein thought, C is the limit, so I would have to assume, since he was right about a LOT of things, that Gravity would travel at C as well."

Perhaps, but Einstein has also been misquoted on quite a few things, too. That's something to consider.

Another thing to consider is that Newton was a rather clever fellow, too, perhaps even in Einstein's league.

...And Newton says that Gravity propagates at near instantaneous speeds.

That's something else to consider.
