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.

Depending on how familiar you are with FQXi, you may know that we like to cause a little mischief at our conferences. Knowing that we had famed string theorist Raphael Bousso and Carlo Rovelli, one of the originators of loop quantum gravity, in the same room, we couldn't resist asking them to debate these rivals routes to a theory of quantum gravity.

Both men are passionate about their work and fierce defenders of their own theories. So, of course, we turned the debate upside down and asked them argue the *reverse* position.

So here's LQG proponent Carlo Rovelli explaining why anyone with any sense would be a string theorist, while string theorist Raphael Bousso staunchly defends LQG as the superior theory:



And if you liked that, here are some of our classic mock debates from our previous meeting.

Julian Barbour and Tim Maudlin reverse debate the reality of time:



And David Albert and David Wallace switch positions on the Many World's Interpretation of quantum mechanics:
