minus-squareQueen HawlSera@lemm.eelinkfedilinkEnglisharrow-up119arrow-down2·1 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.
minus-squareJourei@lemm.eelinkfedilinkEnglisharrow-up32·1 year agoMaybe we could start manufacturing mini black holes to build the dark bulbs!
minus-squarenissenice@lemmy.worldlinkfedilinkarrow-up12arrow-down2·1 year agoNope that’s unfortunately not how black holes work. It would essentially look the same as having the bulb painted black.

minus-squareWanderer@lemm.eelinkfedilinkarrow-up2·1 year agoThat’s the best explanation I have seen for heat. I’ve ran equations for heat so I get it more than most, but always found it difficult to explain.
