SUMMARY

Antoine Tilloy's latest paper introduces a modification of the Ghirardi-Rimini-Weber (GRW) model, proposing that collapse events source a classical gravitational field. This semi-classical theory of Newtonian gravity maintains the statistical interpretation of quantum states and presents new falsifiable predictions, including that particles do not attract themselves and that the gravitational potential is cut-off at short distances (≲10−7m). The model aligns with existing experimental data and offers a framework for testing its predictions against empirical evidence, particularly regarding the decoherence of spatial superpositions.

Ghirardi-Rimini-Weber model with massive flashes
Antoine Tilloy
(Submitted on 12 Sep 2017)
We introduce a modification of the Ghirardi-Rimini-Weber (GRW) model in which the flashes (or collapse space-time events) source a classical gravitational field. The resulting semi-classical theory of Newtonian gravity preserves the statistical interpretation of quantum states of matter in contrast with mean field approaches. It can be seen as a discrete version of recent proposals of consistent hybrid quantum classical theories. The model seems to be in agreement with known experimental data and introduces new falsifiable predictions: (1) particles do not attract themselves, (2) the 1/r gravitational potential of Newtonian gravity is cut-off at short (≲10−7m) distances, and (3) gravity makes spatial superpositions decohere at a rate inversely proportional to that coming from the vanilla GRW model. Together, the last two predictions make the model experimentally falsifiable for all values of its parameters.

Echoes of Verlinde's Emergent Gravity which was found to be close in general terms, but ultimately contrary to, empirical evidence.

I do not see how you can falsify the prediction that particles do not attract themselves, something that the abstract seems to acknowledge in its last sentence.

The second prediction requires a roughly 4 order of magnitude improvement over existing measurements.

I wonder if you can combine Verlinde's Emergent Gravity with Tilloy's.

if experiments are able to bridge the 4 order of magnitude improvement over existing measurements, and find agreement with Tilloy, what would that imply?
