Multi-fold Gravity can Violate Parity Symmetry

A few papers have reported the observation of galaxy asymmetries: when drawing oriented tetrahedrons between galaxies, the left and right oriented distributions are skewed. It seems the reflection of a parity symmetry breaking across the universe. If true, it is considered that it may require New Physics fields, or particles, to explain these observations. It is consistent with earlier work investigating if the CMB, and its polarization, could present Parity symmetry violations. These were conjectured to related to a new field present before inflation, or to the behavior of the quintessence. However, there may be more fundamental mechanisms to justify parity asymmetries, like the result of spacetime orientation by 4D gravity, or gravity itself not always respecting parity symmetry. The former is encountered in the multi-fold electroweak symmetry breaking, when gravity orients spacetime, and the latter is a fundamental property of the multi-fold mechanisms, and multi-fold gravity. Radiated right-handed virtual neutrinos involved in multi-fold gravity are, now unable to interact via the weak interaction, and hoping to hide with the Higgs, which impacts propagation, and therefore the long range massive gravity effects, from when involving left-handed neutrinos. It is a first explanation for parity symmetry violation by gravity. As a results fluctuations, or even larger structures, which are parity images of each other, do not feel gravity effects the same way, nor produce the same gravity effects, even if the difference is small. With inflation and expansion, these effects can become apparent macroscopically and cosmologically. Therefore, the distributions of such structures, like oriented tetrahedra, could differ, as reported to be observed. No need to involve New Physics, in the sense of a new field, or the presence of quintessence, one just needs to consider and include gravity. The most important conclusions is that the multi-fold theory predicted such a P-symmetry breaking in its original paper, and, by now, there may have been observations of such behaviors at cosmological scales, and with tis paper explanation for them. These are additional hints in favor of the multi-fold theory, and how it may apply to our real universe.
