The Takeaway
Physicists discovered a new quantum effect where the invisible ripples of gravity in a vacuum create a tiny 'tug' between masses. This force is unique because it vanishes almost instantly as you move away, becoming 100 billion times weaker if you move just ten times further away.
From the abstract
In the framework of linearized quantum gravity, we investigate the quantum gravitational interaction induced by the gravitodiamagnetic coupling of two massive objects to vacuum fluctuations of the gravitational field. Starting from the Lagrangian of a particle in a gravitational field and employing the formalism of Weyl gravitoelectromagnetism, we derive the interaction Hamiltonian associated with gravitodiamagnetic coupling. Unlike the linear couplings that arise in gravitoelectric and gravitom
