Gravity is usually regarded classically, obeying Newton's law or Einstein's equations. Here I will show that, when the gravitational field is treated quantum-mechanically, the classical trajectories of falling objects are subject to random fluctuations (or "noise"). Intuitively, the fluctuations can be viewed as arising due to the bombardment of the falling object by gravitons. This fundamental noise might be observable at gravitational wave detectors and, if detected, would provide experimental evidence for the quantization of gravity and the existence of gravitons.
