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 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.

Rescuing Reality
A "retrocausal" rewrite of physics, in which influences from the future can affect the past, could solve some quantum quandaries—saving Einstein's view of reality along the way.

A short post to highlight a discussion around one of our recent podcasts. In the April edition of the podcast, I chatted with FQXi’s Markus Aspelmeyer about a proposal for a table-top test for quantum gravity that he and his colleagues had outlined in Nature Physics. The idea is to look for modifications to Heisenberg’s Uncertainty principle due to quantum gravity models, using microscale mirrors in the lab.

During the podcast, we mentioned that Sabine Hossenfelder was quite sceptical about this -- she blogged her concerns that the team failed to address the question of Lorentz-invariance here.

Now one of the paper’s co-authors, Caslav Brukner, has written a response, so I’m inviting you to head over to the podcast thread (and over to Sabine’s Backreaction blog where the same comment has been posted) to discuss that.

In the reductionist way of thinking we meet all kind of problems when reaching the Planck scale. Try the "emergence" way, and a lot of things become easier to understand but also to explain.
