Multidimensional arrow of time

European Physical Journal C: Particles and Fields
This paper investigates the influence of extra dimensions on the nature of the arrow of time. We demonstrate that the observed arrow of time can be explained by the monotonic growth of the multidimensional manifold’s volume.

The Arrow of Time under Space-Time-Entropy Mapping Model [PDF]

ABSTRACT: This study introduces a discrete Time-Entropy Mapping Model (1)where entropy is defined through multiplicative accumulation , rigorously satisfying entropy increase ΔS>0 while maintaining logarithmic consistency with conventional entropy.

Arrow of time and gravitational entropy in collapse [PDF]

Classical and Quantum Gravity
Abstract We investigate the status of the gravitational arrow of time in the case of a spherical collapse of a fluid that conducts heat and radiates energy. In particular, we examine the results obtained by W. B. Bonnor in his 1985 paper where he found that the gravitational arrow of time was opposite to the thermodynamic arrow of time ...

Reversing the Arrow of Time [PDF]

, 2022
The arrow of time refers to the curious asymmetry that distinguishes the future from the past. Reversing the Arrow of Time argues that there is an intimate link between the symmetries of 'time itself' and time reversal symmetry in physical theories ...

Is Time’s Asymmetry Related to Irreversible Processes and the Second Law?

Entropy, 2023
In this article, we start by describing one of the most characteristic properties of time: “time can never decrease”. From this property, numerous authors have concluded that irreversible processes, that always proceed in one direction, must be related ...

Causality Is an Effect, II

Entropy, 2021
Causality follows the thermodynamic arrow of time, where the latter is defined by the direction of entropy increase. After a brief review of an earlier version of this article, rooted in classical mechanics, we give a quantum generalization of the ...

Does a computer have an arrow of time? [PDF]

, 2007
In [Sch05a], it is argued that Boltzmann's intuition, that the psychological arrow of time is necessarily aligned with the thermodynamic arrow, is correct.

Gravitational Entropy and Inflation

Entropy, 2013
The main topic of this paper is a description of the generation of entropy at the end of the inflationary era. As a generalization of the present standard model of the Universe dominated by pressureless dust and a Lorentz invariant vacuum energy (LIVE ...

Wormholes and the thermodynamic arrow of time

Physical Review Research, 2020
In classical thermodynamics, heat cannot spontaneously pass from a colder system to a hotter system, which is called the thermodynamic arrow of time. However, if the initial states are entangled, the direction of the thermodynamic arrow of time may not ...
