Emergence of the Cosmological Arrow of Time from Ultra–Low Entropy Boundary Conditions
This study presents a high-resolution reconstruction of the cosmological arrow of time beginning at 10⁻¹⁰ years after the origin of the universe. Using ultra-low-entropy boundary conditions, near-false-vacuum initial states, and full relativistic field dynamics, the simulation tracks entropy growth, symmetry-breaking transitions, curvature evolution ...

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 ...

Entropy, 2020 The idea that entropy is associated with the “arrow of time” has its roots in Clausius’s statement on the Second Law: “Entropy of the Universe always increases.” However, the explicit association of the entropy with time’s arrow arises from Eddington. In

Gödel's Informational Residue: A Foundational Origin of Entropy and the Arrow of Time
This paper reframes Gödel’s incompleteness phenomena as part of a broader structure of irreversible information. It argues that every act of resolving uncertainty—whether in logic, scientific inquiry, or cognition—requires erasing alternative possibilities, and that erasure carries an objective thermodynamic cost.

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 ...

Arrow(s) of Time without a Past Hypothesis [PDF]
, 2019 The paper discusses recent proposals by Carroll and Chen, as well as Barbour, Koslowski, and Mercati to explain the (thermodynamic) arrow of time without a Past Hypothesis, i.e., the assumption of a special (low-entropy) initial state of the universe ...

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 ...

How many universes are necessary for an ice cream to melt? [PDF]
Serbian Astronomical Journal, 2003 We investigate a quantitative consequence of the Acausal-Anthropic approach to solving the long-standing puzzle of the thermo dynamical arrow of time.

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.
