A subquantum arrow of time

TL;DR

This paper proposes a fundamental 'subquantum arrow of time' arising from energy flux due to fluctuations in theories like stochastic electrodynamics, suggesting a deeper origin of quantum phenomena and matter stability.

Contribution

It introduces the concept of a subquantum arrow of time linked to energy throughput from classical fluctuations, challenging standard quantum mechanics interpretations.

Findings

Energy flux from fluctuations stabilizes matter.

Subquantum arrow of time is more fundamental than thermodynamic or cosmological arrows.

Proposes a deeper physical basis for quantum stability and randomness.

Abstract

The outcome of a single quantum experiment is unpredictable, except in a pure-state limit. The definite process that takes place in the apparatus may either be intrinsically random or be explainable from a deeper theory. While the first scenario is the standard lore, the latter implies that quantum mechanics is emergent. In that case, it is likely that one has to reconsider radiation by accelerated charges as a physical effect, which thus must be compensated by an energy input. Stochastic electrodynamics, for example, asserts that the vacuum energy arises from classical fluctuations with energy $\frac{1}{2}\hbar\omega$ per mode. In such theories the stability of the hydrogen ground state will arise from energy input from fluctuations and output by radiation, hence due to an energy throughput. That flux of energy constitutes an arrow of time, which we call the "subquantum arrow of time". It is related to the stability of matter and it is more fundamental than, e.g., the thermodynamic and cosmological arrows.
