New Extraction of the Cosmic Birefringence from the Planck 2018 Polarization Data

Abstract: We search for evidence of parity-violating physics in the Planck 2018 polarization data, and report on a new measurement of the cosmic birefringence angle, β. The previous measurements are limited by the systematic uncertainty in the absolute polarization angles of the Planck detectors. We mitigate this systematic uncertainty completely by simultaneously determining β and the angle miscalibration using the observed cross-correlation of the E-and B-mode polarization of the cosmic microwave background and the Ga… Show more

“…Spacetime is regarded as a continuum having a dual quantum nature that it curves as waves and, travels as quantum particles at the speed of light; where the latter is justified due to the energy flux from early universe plasma into space at the speed of light creating 'spacetime continuum', 'quintessence', 'vacuum energy', or 'darknesses'. Recent findings regarding light polarization from the CMB support the existence of an exotic substance through space causing these measured polarizations (Minami and Komatsu, 2020). This corroborates the concept of spacetime continuum quantum duality.…”

“…Spacetime is regarded as a continuum with a dual quantum nature, that it curves as waves according to General Relativity while fluxing as quantum energy particles; where the latter is justified because the energy flux from early Universe plasma into space at the speed of light creating a 'spacetime continuum' or 'vacuum energy'. This concept of spacetime quantum duality can be corroborated by recent findings regarding the polarization of light from the CMB, which indicated the possible existence of an exotic substance throughout space that causes these measured polarizations [15]. By using the tracereversed Einstein field equations, the modulus of the continuum, = (stress/strain), is expressed as…”

“…Space-time can be regarded as a continuum with a dual quantum nature, that it curves as waves according to the GR while fluxing as quantum energy particles; the latter is justified because the energy flux from early Universe plasma into space at the speed of light creating a 'space-time continuum' or 'vacuum energy'. This could be corroborated by light polarisation from CMB [7].…”

“…This can endorse the concept of identical matter and antimatter apart of their opposite charge and spin, which undermines the elimination assumption. In addition, the recent observations of parity violations from the CMB [7] could indicate a sided Universe; thus, the experimentally measured parity violations can be an implication of a sided Universe, not an intrinsic asymmetry between matter and antimatter.…”
