http://arxiv.org/pdf/1405.3492v1.pdf The birth of spacetime atoms as the passage of time The view that the passage of time is physical finds expression in the classical sequential growth models of Rideout and Sorkin in which a discrete spacetime grows by the partially ordered accretion of new spacetime atoms. "Sorkin’s suggestion that the birth of spacetime atoms correlates with our conscious perception challenges the view that quantum gravity effects can only show themselves as phenomena in regimes far beyond our immediate reach. The idea is that we may have access, through our intimate experience, to a physical phenomenon that is not present in General Relativity but is part of a more complete theory of spacetime. Lest this seem far-fetched, let me introduce an example from history where an everyday human experience was pointing the way to a new understanding of the physical world, but the lack of a theoretical framework in which to situate and understand this experience meant that it remained (as far as I know) un-articulated until the beginning of the twentieth century". I don't know the implication but would it possible that time is separated from space? There is an ongoing Double ElectroStatic Ion-Ring ExpEriment, DESIREE-- "ions down to their ground state these ions move around rapidly in random directions, but when we cool them, they form this ring and they slow down, and you would expect that at some point, this ring stops moving". I got little information finding related articles. What is the status of the experiment?
