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?

    $\begingroup$ By what definition would this make it "artificial" ? And gravity is independent of a body's rotation rate unless you're proposing some sort of "dumbell" arrangement? $\endgroup$ – Carl Witthoft Mar 30 '20 at 18:45

    $\begingroup$ Making gravitational waves is easy. Making detectable gravitational waves is another matter. $\endgroup$ – user24157 Mar 30 '20 at 19:25

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.

    $\begingroup$ "Any moving mass will generate gravitational waves..." I think you might mean accelerating mass, not just moving. See my mistake of understanding. $\endgroup$ – BMF Mar 31 '20 at 0:33

    $\begingroup$ Not even "any accelerating mass". $\endgroup$ – ProfRob Mar 31 '20 at 6:43

  • $\begingroup$ @peterh-ReinstateMonica I should probably throw a delimiter between that and the "For Monica" part, huh? The BMF moniker is just my initials. $\endgroup$ – BMF Mar 31 '20 at 12:48
  • $\begingroup$ @BMFForMonica Ok, thanks! :-) $\endgroup$ – peterh Mar 31 '20 at 12:57
