"Foundations" argument: Silberstein et al engage Hiley-channeling-Bohm Foundations of Physics (ed. 't Hooft) has accepted this Silberstein et al paper for publication. http://inspirehep.net/record/922919?ln=en which seems to me to resurrect some Bohm trends of thought, perhaps in a new form, and engage those ideas with contrasting ones of the authors. Several of us here (and maybe also in Cosmo forum) have an interest in the often very original ideas of David Bohm (expat American physicist 1917 - 1992) and might find it fun to check this out. Hopefully those who understand Bohmian thought better than I will correct any mistakes on my part. Just for background: http://en.wikipedia.org/wiki/David_Bohm Warning about what seems to me a tendency in Bohm's work toward mysticism decently clothed in abstract language: http://en.wikipedia.org/wiki/Implicate_and_explicate_order_according_to_David_Bohm Basil Hiley's work is in some sense part of the Bohm legacy. Hiley co-authored with Bohm (e.g. http://arxiv.org/abs/quant-ph/0612002 ) after the latter moved to University of London's Birkbeck College. Make no mistake, this is real Foundational stuff! It won't be to everyone's taste, by a long shot. They are speculating about what if anything could underlie the geometry and algebra of existence. And Silberstein et al have their own "pre-geometry" block universe to constrast with the Basil Hiley Bohmian view. A block universe that is not made of the familiar 19th Century differential manifold with its familiar Riemannian 4D continuum machinery, but is instead woven of relationships. It is a "relational blockworld" (RBW) universe which they refer to as "spacetimematter".
