Time as a Metric of Free Energy Capture: A Thermodynamic Arrow of Structure Formation

Abstract

We propose redefining time as an emergent metric that quantifies the proportion of free energy converted into bound states (e.g., mass or structure). This perspective aligns with operational timekeeping: atomic clocks, for instance, define a second based on energy absorption—specifically, 9,192,631,770 hyperfine transitions in cesium-133. Such a concrete example provides an accessible entry point for exploring the idea that time is not a fundamental aspect of spacetime but rather an emergent phenomenon rooted in energy dynamics. Furthermore, we suggest that time’s arrow arises from irreversible energy capture, rendering it undefined in equilibrium states such as the heat death of the universe.

1. Core Premise: Time as Energy Sequestration

Define for a system \( S \):

• \( E_{\text{free}} \): Unbound, disordered energy (e.g., radiation, kinetic).
• \( E_{\text{bound}} \): Energy sequestered into structures (mass, atomic states, etc.).

Metric of Time:

$$ \text{Time}(t) \equiv \frac{E_{\text{bound}}(t)}{E_{\text{free}}(0)} \times 100\%

$$

Support from Atomic Clocks:

• A second is defined by cesium-133 absorbing microwave energy, transitioning between hyperfine states.
• This aligns with our framework: time increments as free energy (\( E_{\text{free}} \)) is absorbed into bound states (\( E_{\text{bound}} \)).
• Key difference: Atomic clocks use frequency (cycles/s), but frequency itself is energy-dependent (\( \Delta E = h \nu \)).
