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.

First Things First: The Physics of Causality
Why do we remember the past and not the future? Untangling the connections between cause and effect, choice, and entropy.

Can Time Be Saved From Physics?
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

A devilish new framework of thermodynamics that focuses on how we observe information could help illuminate our understanding of probability and rewrite quantum theory.

Gravity's Residue
An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.

Could Mind Forge the Universe?
Objective reality, and the laws of physics themselves, emerge from our observations, according to a new framework that turns what we think of as fundamental on its head.

You might be wondering why nobody at FQXi was following last week’s successful launch of the Ariane 5 rocket carrying two new observatories: The Planck mission, which will scan the cosmic microwave background in unprecedented detail; and infrared telescope Herschel that will look for the faint emissions from objects at the edge of the solar system and from distant galaxies. Certainly the missions promise to uncover data that will help answer the sort of foundational questions that are this site’s bread and butter.

The reason, as some may have picked up, was that last Friday FQXi had a (re)launch of its very own, debuting a redesigned website. Many thanks to Christopher Gronbeck and Tien-Yi Lee for the new look. I should add that we didn’t deliberately set our launch date to match the European Space Agency’s in a subversive effort to steal their thunder; it was a coincidence on our part. (Whether ESA deliberately delayed their launch to coincide with ours, however, I cannot say...)

All this is leading up to me saying that, of course, FQXi researchers are thrilled about the prospects of Planck and Herschel. Well, I _say_ that, but a controversial physics birdie whispered in my ear last week that s/he thinks that Planck doesn’t actually have much to offer, and that all the good CMB data was already mined by WMAP. This physics birdie knows his/her stuff, and isn’t affiliated to either to either Planck (well, obviously) or WMAP. So is Planck worth the fuss? I’ll leave that to others who know more about CMB observations to argue over.

In Planck’s defense, I should point to a nice article that ran in Nature a few weeks ago that talked about what Planck might tell us about whether inflation happened or not, with comments from FQXi’s Andrei Linde. It follows earlier hints found in WMAP’s 3-year data that things might not all be smooth sailing for inflation. The excitement around those initial hints has since been dampened, but hasn’t died out completely, and the Nature piece re-analyses the story in light of forthcoming Planck data that might help pick inflation apart from the much more controversial cyclic universe model.

Anyway, back to the more optimistic line, FQXi grant-winner Alex Maloney, for example, hopes that the Planck observations will vindicate his attempts to find to a wavefunction of the universe, by treating the universe as a hologram. You can read more about his work in Anil Ananthaswamy’s article “The Holographic Universe.”

Maloney’s work hinges on the holographic principle, a trick physicists use to handle tough problems by recasting them as equivalent problems in a lower number of dimensions. He isn’t the only one trying to exploit this principle. Others include FQXi grant-winners Subir Sachdev (who wants to use the principle to work out whether string theory could have relevance to the real world, in particular to materials science) and Alex Vilenkin (who is using it to and take a census of all the universes in the multiverse).

So anyway, good luck to Planck, Herschel, and FQXi’s holographic physicists.

The essential question is whether there are polarizations called B-modes in the CMB. These are fossil remnant of gravitational decoupling in inflation.
