👉 In physics, a "slowness" is a measure of how slow something happens compared to other events or phenomena. It can be thought of as the rate at which an object or system moves through space and time. For instance, in classical mechanics, a "slowness" refers to the speed with which a particle or mass decays from its initial state (for example, from rest) to its final state (for example, from a high energy state). In general relativity, a
