Probably a stupid question, but will we ever have something like a microwave to make things cold? Is there a reason this can't exist?lemmy.dbzer0.comimage Melatonin ( @Melatonin@lemmy.dbzer0.com ) Asklemmy@lemmy.ml • 1 year ago message-square59fedilinkarrow-up164

minus-square Queen HawlSera ( @HawlSera@lemm.ee ) linkfedilinkEnglish25•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.
