GRW vs Free Will
By FLORIN MOLDOVEANU
This is my last post on key results that were presented during the New Directions in the Foundations of Physics conference in Washington DC. (You can see my other posts about building a black hole in the lab, how quantum mechanics isn’t as strange as...

Philosophy vs. Physics
By WILLIAM OREM
It’s not quite timeless, but Steven Weinberg’s *Dreams of a Final Theory* is a classic of the popular science genre. In it, he notes that he was an enthusiastic student of philosophy as an undergraduate . . . that is, until “the insights of the...

Definition: Energy

Limits of mathematics in cosmology
By BRENDAN FOSTER
By special request, this forum is opened and dedicated to discussion of the limits or not of mathematics when applied to cosmology.

Complexity
The Fermi Paradox
By WILLIAM OREM
I'd be interested in hearing any proposed solutions to the Fermi Paradox. My experience has been that this is one of the Foundational Questions on which everyone you meet at a party has a ready answer, but the paradox turns out to be surprisingly...

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...

The Destiny of the Universe
By JULIE REHMEYER • Jul 2, 2010
A radical reformulation of quantum mechanics suggests that the universe has a set destiny and its pre-existing fate reaches back in time to influence the past. It could explain the origin of life, dark energy and solve other cosmic conundrums.

The Black Hole Universe
By KATE BECKER • May 28, 2010
Is our universe housed in a black hole? Or did it exist before the Big Bang? If so, we could solve the mystery of dark energy—surprisingly, it could all be down to the humble neutrino.

The Crystallizing Universe
By KATE BECKER • Apr 7, 2010
Explaining how time flows as the present “crystallizes” from the past. The spacetime model could save the concept that the future is open and free will exists—solving the mystery of how photons can time travel along the way.
