Father Time I: Does the Cosmic Microwave Background Radiation Provide a Universal Arrow of Time?

Abstract

in a In order to remove possible misunderstandings regarding this notation in Ref. 2, we have given a detailed operational meaning of this nonlocal GT in Appendix A. 2499 Mod. Phys. Lett.

Father Time Ii: A Physical Basis Behind Feynman's Idea of (Anti)particles Moving Backward in Time, and an Extension of the CPT Theorem to Include Nonlocal Gauge Fields

“…A very simple experimental test for verifying this prediction has been suggested in [2], where it was also shown that the results of a balloon-borne measurement [3] of the cosmic microwave background radiation (CMBR) spectrum does seem to show such a feature a . Subject to verification of the above theoretical prediction, we argued recently [5] that, as a necessary condition for energy conservation in matter-radiation interactions, all particles in the universe subject to electromagnetic interactions should follow this one and the same arrow of time through the agency of the CMBR b . The present paper, which is a companion to [5], addresses reactions which do not conserve energy, but involve mass↔energy conversion, e.g.…”
