Lorentz Violation, Cosmic Microwave Background Radiation Anisotropy and Critical Energy Density of the Universe

Fabio Cardone, Walter Perconti, Andrea Petrucci

ABSTRACT

This paper is dedicated to the comparison of the results of two terrestrial scale experiments with the cosmological evidence of the anomalies/asymmetries of the Cosmic Microwave Background Radiation (CMBR). The first terrestrial experiment is about the violation of Local Lorentz Invariance (LLI) and the second one is about
the emission of neutrons from a steel bar subjected to ultrasounds. Both LLI violation and the neutron emission show a peculiar asymmetry and anisotropy which appear to have an interesting correlation with the direction of some anomalies/anisotropies of CMBR. Besides, it will be shown that the critical energy density of the Universe, as it can be defined by the Friedman equation, is compatible with the energy density of the electromagnetic and gravitational interactions in matter when LLI is violated. It is put forward the idea that this correlation hints at an underlying fundamental anisotropy and asymmetry of the laws of Nature and that in this sense the ‘Copernican Principle,’ stating that Earth is not a privileged observation point in the Universe, may need a deep revision. Earth would be neither a privileged point of observation in the Universe nor a non-privileged one. Due to this underlying asymmetry, it turns out that Earth would be just a point of observation conditioned by natural laws as they appear to be in the area of the universe where Earth is. In this sense, one does not need a spontaneous symmetry breaking in order to describe Nature since the asymmetry is already a fundamental and intrinsic part of it.
