Entropy is the byproduct of a few simple and essential laws governing the universe. These laws themselves are caused by the interactions of various fields. A field is a sort of container that contains only itself. Making distinctions between things that are corporeal and incorporeal is already outside the scope of usefulness.
A body attempts to maintain homeostasis and must, as a result, fight to keep entropy low, consuming energy and radiating, convecting, conducting it to be less affected by its environment, to be less like an ice cube. A body is an organized structure mimicking equilibrium even as it fights to slow the process by which it might actually achieve it. Earth is a body too.
Cruise control is as homeostatic a process as any happening in a body, it’s equilibrium neither a destination itself nor necessarily working to reach one, simply time laid on its side and allowed to stretch forward.
