To what degree would a non-spinning, non-moving black hole necessarily produce even very weak gravitational waves? Would some be produced as matter/energy reaches it? If so, would no gravitational waves at all be produced if nothing was reaching it, hypothetically? (I suppose these same questions apply to all massive objects.)
- scatters 3y agoA radially symmetric object does not produce gravitational waves, whether it is spinning or not, since it has zero quadropole moment.

If it's perfectly non-spinning, and nothing is falling into it, then it emits no gravitational waves at all. If matter or energy falls in, and does so in a manner that is not spherically symmetric (which will most likely be the case), then some very weak gravitational waves will be emitted. But they will be much, much too weak for us to have any hope of detecting them. Even a gravitational wave detector like LIGO in the same stellar system would have difficulty detecting them.
