minus-squareQueen HawlSera@lemm.eelinkfedilinkEnglisharrow-up3·1 year agoThe problem is that cold is merely the absence of heat, you can't inject cold into something or generate cold, because there is no such thing as cold. It's kind of like how we can make a light bulb, but we can't make a dark bulb.
