    The 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.

      Maybe we could start manufacturing mini black holes to build the dark bulbs!

        Nope that’s unfortunately not how black holes work. It would essentially look the same as having the bulb painted black.

          Practically speaking I think having a mini black hole in your home would look like being rapidly crushed to death.

          I bet if you had a black hole with a wall on one side and a light on the other, it’d cast a really trippy shadow.

        Sadly, a mini black hole would suck up everything around it. Much like a tiny Katamari Damacy, it would quite quickly consume everyone and everything around it. Of course after not too long it would become a regular sized black hole.

          Some mini black holes do not grow into black holes. They collapse. The issue is that they aren’t stable for any decent length of time. Fractions of a nanosecond.

            A capitalist haven, think of how many black holes one could sell!

      That’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.
