Actually, the disturbance propagates throught the sheet at a speed v <= c (in some situations, <= speed of sound in the material). The speed of light is not just a good idea - it's the law. > One way that seems interesting would be to annhilate a certain > weight of matter and measure the gravitic disturbance. This was discussed here recently. The weight (mass) is not annihilated, it is transformed to another state (which may then depart at v == c). A better way is to accelerate a mass and look for gravity waves. -- Gene E. Bloch (...!nsc!voder!gino) Try to understand.
