Our Not-So-Special Universe
By ZEEYA MERALI
Last year we briefly noted that a paper by FQXi grant winner Fred Adams was getting a lot of attention on science websites. The paper caused a stir because it called into question whether some of the fundamental constants in the universe really are...

Alternative Models of Cosmology
By ANONYMOUS
In cosmology, it is believed that regions of space on `opposite' sides of the universe are too far apart to have ever been causally connected. That is, they are outside each other's `particle horizon'. Consequently, it is difficult to explain the...

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 Theorem...

Tegmark's Mathematical Universe
By ANTHONY AGUIRRE
While he would be too modest to toot his own horn, there's nothing stopping me from pointing out that 'mad Max' has recently put out a very interesting paper on whether all possible formal systems (and the 'physical' universes that some subset of...

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.
