All homogeneous pure radiation spacetimes satisfy the Einstein-Maxwell equations
C. G. Torre
TL;DR
This paper proves that all homogeneous pure radiation solutions to Einstein's equations necessarily include electromagnetic sources, correcting a previous misconception in the scientific literature.
Contribution
It establishes that every homogeneous pure radiation spacetime must have electromagnetic sources, clarifying a long-standing misunderstanding.
Findings
All homogeneous pure radiation solutions admit electromagnetic sources
Corrects an error in previous literature regarding these solutions
Provides a complete characterization of such spacetimes
Abstract
It is shown that all homogeneous pure radiation solutions to the Einstein equations admit electromagnetic sources. This corrects an error in the literature.
