    Would this work?

    Suppose I had a large dense weights suspended vertically and moved under computer control to swing in some pattern.

    Would a gravitometer at some distance be able to detect the change in motion?

    while whatching 'the Elegant Universe' i saw that there was an idea in M-theory that since the strings that govern the state of gravity were closedm loops they could escape from one Brane or universe causing a gravity wave, that is how i think scientists are trying to see the Graviton, it was also suggested that the exchange of Gravity waves viewed by other branes could be used for communication, this was really just used as an explanation.

    Detecting gravity waves is proving difficult at the moment. There are some experiments looking for them (LIGO), which should detect gravity waves from collapsing stars etc, but afaik, none so far have been detected.

    It's possible in theory, but since gravity changes travel at the speed of light there wouldn't be any speed advantage.

    the types of gravity waves being looked for are the rippling effects created by black holes.

    this experiment proposes to find infinitesmaly small grav waves by letting a graviton escape from our universe, that is if the Theory is right. (M-Theory)

    just another item on the LHC to do list

    Yes! But maybe not in that exact way. I have heard that gravity waves may be the best way to communicate through space. Aliens may be sending messages with it right now that we can just not decipher yet.

    but then the signal could possibly be disrupted when it mingles with the Gravitational field of another star or Stelar system
