What Could Spacetime Geometry Emerge From?
In the previous essay, I asked what current physics would require if spacetime geometry were emergent rather than fundamental. Observation placed surprisingly strict demands on any deeper organization. Whatever lies beneath geometry would need to transmit influence across distance, preserve conservation relationships, respond dynamically to matter and energy, remain stable under extreme conditions, be Lorentz…

What Exists Between Substance and Geometry?
My last essay discussed the puzzle Einstein encountered when he recognized that the geometry of spacetime appeared to possess physical qualities. Geometry is normally understood as a way of organizing relationships between objects. In general relativity, however, spacetime geometry bends light, governs motion, participates in energy exchange, and transmits gravitational waves. A framework that influences…

Exploring Spacetime and Einstein’s Puzzle
My last essay noted that spacetime is often treated as a dynamical object yet is not considered a substance. General relativity describes gravity as geometry, but if spacetime curvature stretches, evolves, and propagates waves, what kind of physical reality does that geometry actually represent? This question is not new. A century ago, Einstein confronted that…
