- Description
- Glasses evolve slowly, but the precise speed at which they do so is easily affected in many ways, for example shearing them (in practice) or using a clever unphysical algorithm (in the computer). Remarkably, the actual evolution is always the same, except for a speeding up, just like projecting the same film at varying speed. Technically speaking, this is "time-reparametrization softness", which I will argue is at the heart of glassiness. Quite astonishingly, the very same property has appeared in toy quantum models of gravity, and there again, time reparametrization softness is at the heart of the emergence of gravity as a low energy limit.
