I provide a simple argument that the experimental observation of gravitationally induced entanglement rules out the validity of current gravitational collapse models. This is consistent with the recent claim to the contrary in [Trillo and Navascués, Phys. Rev. D, 111, (2025)], if one takes into account the physical constraints of actual table-top gravity experiments.

Je présente un argument simple pour montrer que l’observation expérimentale de l’intrication induite par la gravitation exclut la validité des modèles actuels d’effondrement gravitationnel. Ceci est cohérent avec l’affirmation récente du contraire dans [Trillo et Navascués, Phys. Rev. D, 111, (2025)], si l’on prend en compte les contraintes physiques des expériences gravitationnelles réelles sur table.
