T violation and the unidirectionality of time

TL;DR

This paper explores how T violation experiments suggest a fundamental asymmetry in time, proposing that T violation leads to a universe that effectively follows a unidirectional time path, impacting our understanding of time's nature.

Contribution

It introduces a novel interpretation that T violation causes destructive interference between time paths, explaining the unidirectionality of time and offering new insights into quantum gravity and the nature of time.

Findings

T violation induces destructive interference between time paths

Evidence indicates the universe follows a specific time direction

Implications for quantum gravity and the origin of time's arrow

Abstract

An increasing number of experiments at the Belle, BNL, CERN, DA{\Phi}NE and SLAC accelerators are confirming the violation of time reversal invariance (T). The violation signifies a fundamental asymmetry between the past and future and calls for a major shift in the way we think about time. Here we show that processes which violate T symmetry induce destructive interference between different paths that the universe can take through time. The interference eliminates all paths except for two that represent continuously forwards and continuously backwards time evolution. Evidence from the accelerator experiments indicates which path the universe is effectively following. This work may provide fresh insight into the long-standing problem of modeling the dynamics of T violation processes. It suggests that T violation has previously unknown, large-scale physical effects and that these effects underlie the origin of the unidirectionality of time. It may have implications for the Wheeler-DeWitt equation of canonical quantum gravity. Finally it provides a view of the quantum nature of time itself.
