Dynamic Substrate Theory - Premises and Promising Directions for Research - A Conceptual Review of Promising Ideas
Year: 2026
Type: article
Abstract: This article offers a constructive reading of Dynamic Substrate Theory (DST), focusing on ideas that open promising avenues for research. It begins with a longstanding question. Physical theories describe with great precision how gravity manifests itself, but how far do they explain the underlying physical reality that gives rise to it? DST explores the possibility that space, fields, and matter can be understood in terms of an underlying physical reality composed of persistent entities that interact locally. Its present value lies in framing this question as a research program and exploring its conceptual, mathematical, and observational implications. Two hypotheses stand out. The first is that gravity may emerge from fundamental electromagnetism. The second is that light deflection around a magnetar may differ both between its two poles and between its polar and equatorial regions. An observable difference of this kind would be of considerable scientific interest and could mark a milestone in the assessment of DST, provided that the observations were evaluated against both a quantitative prediction from the theory and competing explanations.
