Vacuum Radiation, Entropy and the Arrow Of Time
2002The root mean square perturbations on particles produced by vacuum radiation must be limited by the uncertainty principle, i.e., 1/2 1/2 =ħ/2, where 1/2 and 1/2 are the root mean square values of drift in spatial and momentum coordinates. The value 1/2 =(ħt/m) 1/2 , where m is the mass of the particle, can be obtained both from classical SED ...

Macroscopic laws, microscopic dynamics, time's arrow and Boltzmann's entropy
Physica A: Statistical Mechanics and its Applications, 1993Abstract I discuss Boltzmann's resolution of the apparent paradox: microscopic dynamics are time-symmetric but the behavior of macroscopic objects, composed of microscopic constituents, is time-asymmetric. Noting the great disparity between macroscales and microscales Boltzmann developed a statistical approach which explains the observed macroscopic ...

From Randomness and Entropy to the Arrow of Time
The Element reconstructs, analyses and compares different derivational routes to a grounding of the Arrow of Time in entropy. It also evaluates the link between entropy and visible disorder, and the related claim of an alignment of the Arrow of Time with a development from order to visible disorder.openaire +2 more sources
Time Reversal, Entropy, and Computational Evolution: A Unified Perspective on the Arrow of Time
We investigate the fundamental nature of time-reversal symmetry and its progressive breakdown in complex, structured dynamical systems. Drawing on the Fluctuation Theorem and recent advances in quantum time-reversal experiments, we reveal that the process of computational evolution—by which systems develop increasingly sophisticated mechanisms to ...+4 more sources
From Order to Entropy: How Gravity Shapes Time's Arrow
This educational handout by Matthew J. Hall, created with assistance from GPT-5 Thinking, provides a clear, step-by-step introduction to the relationship between entropy, gravity, and the arrow of time.Written in plain language for students and general readers, it explains how microscopic dynamics and coarse-graining produce the Second Law of ...Hall, Matthew +1 more

Entropy, Information & the Arrow of Time in the Monadic Electron Universe
The study links entropy growth, time-irreversibility, and quantum entanglement to the topology of a single electron–positron world-line (“the monad”) that knots and links through space-time. A topological entropy S_topo is defined as the Boltzmann constant times the logarithm of the path-integral weight Omega(K) for each knot or link class K.openaire +1 more source

The Impossibility of Entropy Reversal: Energy Dispersion and the Arrow of Time
This paper offers a rigorous physical analysis of entropy, challenging common misconceptions that equate it with disorder or statistical abstraction. It argues that entropy is best understood as the irreversible dispersal of usable energy, governed by geometric principles and radiative loss.openaire +1 more source
Timeless Quanta: A Threshold for Mass, Entropy, and the Arrow of Time
This paper presents the Timeless Quanta (TQ) framework, a novel theoretical model proposing that mass, entropy, and the direction of time emerge from a universal curvature threshold (Θc\Theta_cΘc) in spacetime. The framework models quantized collapse shells with a hybrid Gaussian-exponential profile, calibrated solely to the proton mass (rc=0.423 fmr_copenaire +1 more source
