Is it possible make artificial gravitational waves? Is it possible to generate gravitational waves (creating low or high disturbance in space-time) from very heavy bodies spinning at very high speed artificially?
Typical accelerating masses will generate gravitational waves.  but because gravity is so weak of a force; and current/plausible near future detection apparatus will be unable to detect signals from anything less dense than gravitationally stable masses of degenerate matter (ie neutron stars or white dwarfs) moving at near relativistic speeds.
