    I was writing a science fiction story involving the building of a large sphere of metal with an advanced power source able to vibrate this sphere at speeds beyond the speed of light. In my story the sphere then dropped out of its present place in the universe into a void until the vibration slowed and they dropped back in to the universe. The universe having continued moving while the sphere wasn't it would have "stuck" in the stream of the universe's movement like a rock in a river. With my imagined power source is this possible?....and would this not only be movement in space...but time also? I would appreciate any input. I also have other questions.

    It is generally accepted that nothing can move faster than the speed of light. Vibrating would require that the surface of the sphere not only move faster than the speed of light but also have very high accelerations and hence forces. I cannot conceive how this could happen and what how much energy would be required to accomplish this.

    I would think that the stresses in the skin of the sphere would cause the material to fail long before "light speed" vibrations could occur.

    If this is possible then you need to approach a theoretical physicist not a nuts and bolts engineer.
