Photon Mixing in Domain Walls and the Cosmic Coincidence Problem
A model is presented where there exists another U(1) gauge group which is extremely weakly coupled to that of QED except inside the core of domain walls. It is possible to choose parameters such that standard model photons crossing such a wall are mixed maximally with the ’para-photons’ of the other U(1). We use this model to explain the apparent low luminosity of high redshift supernovae. A po...
متن کاملPhysical Vacuum and Cosmic Coincidence Problem
A framework is suggested in which the energy integrals of the Friedmann cosmology are identified as genuine time-independent physical characteristics for both vacuum and non-vacuum forms of cosmic energy. The integrals are found to be numerically coincident within two orders of magnitude. It is assumed that this coincidence reveals a symmetry that relates vacuum to non-vacuum forms of cosmic en...
متن کاملCosmic Walls and Filaments Formation in Modied Chaplygin Gas Cosmology
We want to study the perturbation growth of an initial seed of an ellipsoidal shape in Top-Hat collapse model of the structure formation in the Modied Chaplygin gas cosmology. Considering reasonable values of the constants and the parameters of the model under study, we can show that a very small deviation from spherical symmetry (ellipsoidal geometry) in the initial seed leads to a nal highly ...
متن کاملCosmic Acceleration versus Axion-photon Mixing
Axion-photon mixing has been proposed as an alternative to acceleration as the explanation for supernovae dimming. We point out that the loss of photons due to this mixing will induce a strong asymmetry between the luminosity, dL(z), and angular diameter distance, dA(z), since the latter is unaffected by mixing. In a first search for such an asymmetry, we introduce a dimensionless mixing amplit...
