Time and the Nature of Reality
By ZEEYA MERALI
We recently ran an article (courtesy of Nautilus Magazine) in which physicist Paul Davies ran through some open questions about the nature of time.

I want to alert you to another discussion currently taking place on the Big Questions Online...

By WILLIAM OREM
Everyone is talking this week about the dramatic confirmation of inflationary theory: those first-instant gravitational waves whose details may even point--being, if you will, quantum phenomena that went suddenly ultra-macroscopic--toward the correct...

BICEP2: Primordial Gravitational Waves & Evidence...
By ZEEYA MERALI
Updated: Congratulations to FQXi's Alan Guth and Andrei Linde following the announcement of the first direct detection of B modes -- evidence of their inflation theory. Well done to those working on BICEP2, and all others who have contributed to the...




NEW PODCAST EPISODES
Max Tegmark proposes that consciousness may be another state of matter in his talk at the 4th FQXi International Conference.
Sean Carroll questions conventional wisdom on quantum fluctuations, whether we might be disembodied "Boltzmann Brains" floating through space & eternal inflation leading to a multiverse, in his talk at the 4th FQXi conference.
"What is quantum information *really* good for?" Physicists William Wootters, Caslav Brukner, Andrew Briggs, Raymond Laflamme, Sorin Paraoanu & Gerardo Adesso discuss this question at FQXi's 4th International Conference in Vieques.

By JOY CHRISTIAN
I wish to mention a recent preprint of mine---this one---which is about the prevalent (but false) belief in “quantum non-locality.” I am, in fact, required to post this link here, because this preprint is part of my forthcoming book on Bell’s...

Ultimate Reality
The limits of mathematics
By IAN DURHAM
I realize this forum hasn't gotten much action lately, but I'm hoping enough people pop on here that I get some feedback on this (particularly some of the membership who may have worked on or thought about related problems).

Alternative Models of Reality
By ZEEYA MERALI
If you have an unconventional, alternative model of reality, then this is the place to discuss it. (This is for contributors who have preliminary ideas and would like feedback, but do not have an academic paper or arXiv preprint and have not given a...

Readers' Choice: Cheating the Causal Game
By SOPHIE HEBDEN • Jun 24, 2013
A new quantum framework that blurs cause-and-effect at a fundamental level could improve information processing and lead to a theory of quantum gravity.

A View From the Top
By KATE BECKER • Apr 8, 2013
Thinking of causation as a "two-way street"—along which the passage of information can be inverted—could have implications for the origin of life.

Classic Article: Black Holes, Paradox Regained
By ANIL ANANTHASWAMY • Mar 18, 2013
In 2004, Stephen Hawking famously conceded that black holes do not devour all information when they swallow matter—seemingly resolving the "black hole information paradox" that had perplexed physicists for decades. But some argue that the paradox remains open, and we must abandon our simple picture of spacetime to unravel it.
