Causality and gravity: https://arxiv.org/abs/2106.05912
John F. Donoghue, Gabriel Menezes
We show how uncertainty in the causal structure of field theory is essentially inevitable when one includes quantum gravity. This includes the fact that lightcones are ill-defined in such a theory - independent of the UV completion of the theory. We include details of the causality uncertainty which arises in theories of quadratic gravity.
