If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Quantum Limits of Knowledge 2021

Tuesday 30th March, 2021

We argue that in canonical quantum gravity there is no fundamental Born rule at the level of the Wheeler-DeWitt equation, and that an effective Born rule emerges only in the Schrödinger approximation for quantum systems on a classical spacetime background. Furthermore, we show that small quantum-gravitational corrections to the Schrödinger equation can render the Born rule unstable. These results are shown to arise naturally in the de Broglie-Bohm pilot-wave formulation of canonical quantum gravity.
