    Not really proven. It’s theorized to be possible, but nothing emits cold that we know of in the same way. Microwaves, use waves (citation needed) to heat up the food, cold to our know doesn’t work the same way.

      That’s because cold doesn’t exist as a thing. Cold is just a lack of heat. You can only take the heat out of something, not add cold to something.
