Cosmology
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...

Cosmic Origins
Is the Past Infinite?
By WILLIAM OREM
I interviewed some non-mainstream cosmologists last year for an article, such as those at the Alternative Cosmology Group who hosted the Crisis in Cosmology conference in Portugal in 2005. These are credible folks who think the Standard Model (the...

Ultimate Reality
Quantum Coherence = Entanglement
By ZEEYA MERALI
I'm opening this thread shamefully late, based on recent FQXi funded research by Gerardo Adesso and colleagues, whose work was covered in Phys.Org -- as spotted at the time, by John Merryman.

We will, of course, be covering Adesso's work in...
