This research contributes to the ongoing study of quantum field theory, general relativity, and the search for a unified theory of everything.
• Key terms: Quadrupole moment, gravitational waves, quantum fluctuations, strong equivalence principle, black hole precession, and the decoherence function.

To understand this study, imagine the universe is a high-stakes poker game where Alice is trying to keep her cards hidden. Bob wants to cheat by using a super-sensitive telescope, a rotating black hole, to peek at her reflection from across the room.
In a purely classical world, Bob might succeed and break the rules of the game. However, this paper shows that the "air" in the room is naturally filled with quantum static or noise. This noise is so fundamental that even the most powerful black hole telescope cannot see through it clearly enough to cheat. This quantum noise acts like a cosmic referee, ensuring that information cannot travel faster than light and that the fundamental laws of cause and effect remain unbroken.
Essentially, the researchers proved that for the universe to make sense, even the massive ripples from black holes must be quantised.
