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.

Pages 7 and 8 of this essay contain a result about gravity that has been overlooked until now- namely that the undecidability of the homeomorphy problem applies to causal diamonds because they are compact 4-manifolds.

In other words, undecidability is imbedded in the equations of general relativity.

A new era dawns.  Old questions become quaint and historical.  Is the whole community ready?  Or is physical reality too dangerous for our collective understanding at this time?

That's a good question, Sherman. Thank you.

The math is incredibly simple. The wave-particle duality of quantum theory has a correspondence with the consistent-complete "duality" of undecidability. This does away with the need for quantum interpretations and gives us a new connection to gravity.
