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?

    This is a bit like asking if we could build a flashlight that emits a beam of darkness I think

      It’s not. A device that rapidly cools things down placed inside it isn’t implausible. He’s not asking for a beam of absence, he’s asking for an enclosed space that subtracts heat.

        Shooting something with “cold energy beams” is an anti-microwave

        We aren’t talking about machines to make things cold, I was asked if we could make microwaves that make stuff cold

        I do believe that’s a freezer.

          Yes or one of those weird ice cream things that has an extremely cold surface, or one of those things where you roll it in ice water or a million machines. “Machine that makes things cold” isn’t sci fi.

      Very much so, and equally possible in theory (interference patterns with light exist, light cancellation could work somewhat like noise cancelling) but also equally impossible to do at anything much above an atomic scale.
