Classical Universes and Quantized Particles from Five-Dimensional Null Paths

TL;DR

This paper proposes a model where 4D objects follow null paths in 5D, leading to insights into classical universes and quantized particles, with implications for fundamental physics and cosmology.

Contribution

It introduces a novel 5D null path framework to model classical and quantum phenomena, connecting extra-dimensional geometry with observable physics.

Implications for the Weak Equivalence Principle

Insights into the cosmological constant

Potential applications in astrophysics

Abstract

All objects in 4D spacetime may in principle travel on null paths in a 5D mani-fold. We use this, together with a change in the extra coordinate and the signature of the metric, to construct a simple model of a classical universe and a quantized particle. There are notable implications for the Weak Equivalence Principle and the cosmological constant, and for astrophysics.
