# The Sovereign Mirror and the Theory of Sovereign Reflectivity (TSR) > tsr.wtf is the home of *The Sovereign Mirror: A Conversation About Consciousness, Resistance, and the Present* by Nicholas Ferguson (2026), and of the Theory of Sovereign Reflectivity (TSR) it tells. TSR starts from one rule: the main difference between the physical and the nonphysical is resistance. Physics already measures resistance, and calls it mass. So take what physics knows and reflect it: keep each relationship, flip the condition. Resistant becomes receptive, limited becomes limitless, radiating becomes collecting. The site itself is an interactive page that needs JavaScript. This file and the Markdown files linked below carry its content in plain text. The mirror, physical on the left and its nonphysical reflection on the right: - mass (resistance to a change in motion) → Movement (receptivity to a change in motion) - the speed of light → the Current - space → Vibration - time → Expansion - acceleration → Appreciation - force → Frequency - density × volume → Desire × Vibrance - focus → Tune - empirical evidence (a change in force, measured) → emotional evidence (a change in frequency, felt) - gravity well → Vortex - gravitational lensing → Diffraction & Convergence - E = mc² → C² × M = E, read whole as C² × M = E = M × C² The relationships carry across the mirror. The quantities don't. ## Start here - [The Reflection Game](https://tsr.wtf/reflection-game.md): the rule, the full table, what holds each word in place, the three tests, the traps and the swaps that failed.
