The literature on quantum-gravity-inspired scenarios for the quantization of space-time has so far focused on particle-physics-like studies. This is partly justified by the present limitations of our understanding of quantum gravity theories, but we here argue that valuable insight can be gained through semi-heuristic analyses of the implications for gravitational phenomena of some results obtained in the quantum space-time literature. In particular, we show that the types of description of particle propagation that emerged in certain quantum space-time frameworks have striking implications for gravitational collapse and for the behavior of gravity at large distances.

Abstract
The literature on quantum-gravity-inspired scenarios for the quantization of space-time has so far focused on particle-physics-like studies. This is partly justified by the present limitations of our understanding of quantum gravity theories, but we here argue that valuable insight can be gained through semi-heuristic analyses of the implications for gravitational phenomena of some results obtained in the quantum space-time literature. In particular, we show that the types of description of particle propagation that emerged in certain quantum space-time frameworks have striking implications for gravitational collapse and for the behavior of gravity at large distances.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
