Thanks for the reference - but I had a problem with it. It shut down my Internet Explorer for some reason. I found this article, which may be the same thing, at http://xxx.lanl.gov/abs/gr-qc/9903045 Norman ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ General Relativity and Quantum Cosmology, abstract gr-qc/9903045 From: Carlo Rovelli [view email] Date: Fri, 12 Mar 1999 15:05:25 GMT (40kb)
Quantum spacetime: what do we know? Authors: Carlo Rovelli Comments: To appear on: "Physics Meets Philosophy at the Planck scale", C Callender N Hugget eds, Cambridge University Press This is a contribution to a book on quantum gravity and philosophy. I discuss nature and origin of the problem of quantum gravity. I examine the knowledge that may guide us in addressing this problem, and the reliability of such knowledge. In particular, I discuss the subtle modification of the notions of space and time engendered by general relativity, and how these might merge into quantum theory. I also present some reflections on methodological questions, and on some general issues in philosophy of science which are are raised by, or a relevant for, the research on quantum gravity. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ----- Original Message ----- From: "scerir" <[EMAIL PROTECTED]> To: <everything-list@eskimo.com> Sent: Wednesday, June 01, 2005 12:55 PM Subject: Re: objections to QTI Norman Samish wrote: This scenario that you are discussing reminds me of this interview with Julian Barbour where he proposes that "time" is an illusion. This reminds me of a good paper by Carlo Rovelli (about quantum gravity, GR, space-time, etc.) http://ws5.com/copy/time2.pdf in which he suggests that the temporal aspects of our world have a statistical (thermodynamical) origin, rather than dynamical. Time is our incomplete knoweldge of (the state of) the world. Not sure, though, whether the motto "Time is ignorance" can solve the question, by SPK, about the quantum, or indeterministic, "block universe". s. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
