INTRODUCTION

English translation pending.

CORE DEFINITION

A concept from quantum field theory, developed from the 1970s work of Sidney Coleman and others on vacuum stability. A scalar field may rest in a local minimum of its potential, a false vacuum, which is stable on ordinary timescales but is not the lowest-energy state. Quantum tunnelling can nucleate a bubble of true vacuum, which then expands at close to the speed of light and converts the surrounding region. Inside, the values of physical constants and the masses of particles differ. Measurements of the Higgs mass place the Standard Model near the boundary of stability, though the expected lifetime vastly exceeds the age of the universe.

SCAFFOLDING EFFECT

Reduce cognitive load

- Stability audit: Ask whether a system's equilibrium is a local minimum or the global one. - Phase-change watch: Look for a trigger that could nucleate a transition and how fast it would spread. - Rewrite risk: Treat ground-up replacements as discontinuous rather than gradual.

Anchor fast decisions

Energy landscapes can have several minima. A system in a higher minimum is stable against small perturbations, because local fluctuations cannot carry it over the barrier. Tunnelling is not a small perturbation, and once a lower minimum exists the surface energy of the new phase is finite, so the bubble grows rather than collapses. The transition is driven not by the size of the disturbance but by the existence of a lower state and the probability of reaching it, making it both astronomically rare and total.
