It is strange that cold after heat registers as a pleasant tingling across the skin. Why is it pleasant? Why do we call it pleasantness? It is stranger to think that the cold, wonderful and skin-tingling, will persist long beyond the end of all terrestrial life, or that the same sights capable of producing a similar frisson will continue to glow to the blindness of lifeless space in which the planets and stars would simply be nameless balls of gas. Maybe in a distant galaxy in a hubble volume we will never visit an alien lifeform understands the cold as blazing surges of pain across tongue-like appendages or maybe sees stars in ultraviolet and other radiation and responds to them in fear instead of wonder. I find it strange our tendency to be happy simply because the molecules in the air are vibrating infinitesimally slower than usual.
