Is a change in gravity felt instantaneously on the other "side" of the universe?

[Axuality]

That is, does gravity travel instantaneously? Have we ever been able to measure the speed with which 'gravity travels'?

[Sorry!]

I'm pretty sure the speed of gravity is theoretically = to c. I think an experiment was done a few years ago to determine this actually... I'm not sure of the results.
