TL;DR
This paper extends general relativity to higher dimensions, showing that in a 5D Kaluza-Klein model, particle mass and spin can vary along their worldlines due to extra dimensions.
Contribution
It introduces a method to incorporate higher dimensions into spacetime measurements, revealing mass and spin variations in a 5D Kaluza-Klein framework.
Findings
Mass varies along particle worldlines in 5D models
Spin variations are explored within the 5D context
Higher dimensions influence classical measurement results
Abstract
We extend the classical general relativistic theory of measurement to include the possibility of existence of higher dimensions. The intrusion of these dimensions in the spacetime interval implies that the inertial mass of a particle in general varies along its worldline if the observations are analyzed assuming the existence of only the four spacetime dimensions. The variations of mass and spin are explored in a simple 5D Kaluza-Klein model.
