A black hole large enough to take a sizable object creates a significant gravitational disturbance over a large distance.

Probably it was torn away from its parent-star by some gravitational disturbance, and has been drifting through the void ever since.

I hope I can learn more about the gravitational disturbances from the framing of their questions.

Other locations show similar levels of gravitational disturbance.

"Level of gravitational disturbance was marginally higher."

It is possible subject cannot explain gravitational disturbances.

"But you had some advance evidence of the singularity, did you not, due to the gravitational disturbance?"

The Hammer operates by creating a gravitational disturbance.

One possibility is that gravitational disturbances caused by massive planets or passing stars ejected the bodies from their home planetary systems.

As predicted, the barrier yields no harmful radiation or gravitational disturbances.
