The birth of spacetime atoms as the passage of time

TL;DR

This paper discusses a model where the passage of time is represented by the discrete growth of spacetime atoms, aligning with physical theories of temporal passage.

Contribution

It introduces a classical sequential growth model where spacetime evolves through the accretion of discrete spacetime atoms, providing a new perspective on the nature of time.

Findings

Spacetime can be modeled as discrete atoms growing sequentially.

The model aligns with physical theories of the passage of time.

Provides a framework for understanding temporal evolution in quantum gravity.

Abstract

The view that the passage of time is physical finds expression in the classical sequential growth models of Rideout and Sorkin in which a discrete spacetime grows by the partially ordered accretion of new spacetime atoms.
