The far infrared region of the standard model vacuum as a possible gravity analogue. |

Abstract |
It has been argued by many authors that the space-time curvature observed in gravitatinal field might emerge from the dynamical properties of the physical flat-space vacuum in some hydrodynamic limit. To exploit the implications of this idea and construct a definite model of gravity, one could start from the physical vacuum, modeled as a Bose condensate of elementary quanta, and look for vacuum excitations that, on a coarse grained scale, resemble the Newtonian potential. In this way, it is relatively easy to match the first approximation to the line element of General Relativity or of some of its possible variants. As an underlying physical mechanism, I consider ultraweak scalar fluctuations in the far infrared region of the standard model vacuum (details in arXiv:0904.1272[gr-qc]). |
