I’ve been thinking about this all night and feel as if I should know this. What is cold, is it the lack of heat or an actual different thing? In other words, are hot and cold real tangible space occupying things and how so?
Temperature is energy! But what does that mean? Basically, all the particles we’re made up of can become energized, meaning they move around more. We experience this as heat, and, yes, cold is the lack of heat, or just atoms not moving around very much.
