Gravity’s Gentle Touch Erases Quantum ‘Magic’ экспресс
A coffee whirlpool can span two spots in a cup — a blur of swirling liquid. Quantum particles behave similarly: a spacetime whirlpool where they exist in two places at once. But gravity acts as the spoon that stirs the fabric of space and time. The particle’s mass generates tiny ripples — gravitational waves — that drain the whirlpool’s energy. Each ripple whispers the particle’s location, and as whispers accumulate, the blur collapses into a single position. The process follows a rule from Ludwig Boltzmann: just as heat spreads disorder, every ripple broadcasts the particle’s secret. Heavier objects with wider whirlpools fade faster. For a grain of sand, gravity alone would collapse a superposition in a trillionth of a second — no measurement needed. This matches Roger Penrose’s hunch that gravity curbs quantum strangeness. Experiments with tiny mirrors may soon connect the two pillars of physics: the quantum rulebook and Einstein’s gravity.

Some collapse models proposed that gravitational effects cause the instability of mass distribution superpositions, leading to wave function collapse. In this paper, we utilize the quantum Boltzmann equation (QBE) to analyze the behavior of a fermion in a spatial superposition under graviton emission. We introduce a quantitative measure that links the stability of the superposition to the spatial separation, particle mass, and gravitational coupling. By examining the collision term in the QBE, we derive the decoherence rate and show how it depends on these parameters. Our results provide a detailed framework for understanding gravity induced decoherence, bridging the gap between quantum field theory and collapse models. We also discuss the implications of these findings for experimental tests of gravitationally induced wave function collapse and the broader class of collapse models known as dissipative continuous spontaneous localization (CSL) model.
A single graviton is so weak that a billion billion of them could barely lift a paperclip, yet their combined whisper collapses a quantum state.
