A microwave is a magnet-based device that makes things very hot

No. A "microwave oven" is a device that uses a magnet to make "microwaves" -- actual waves of energy. The microwaves then impart their energy into whatever they hit to make it hot.

You cannot "make things cold". Cold is not a thing. It is the lack of heat. You can only give the heat energy somewhere to go by providing something colder.

I had a friend make a "fridge" with a microwave.
So yes.

I don't know why I chuckeled at this, this much

according to some interpretations of qm negative energy waves are possible

If this interpretation is correct and if you can build a device to generate such waves then yes.

This also gives rise to the possibility of cold lasers

(Freeze rays lol)

Too bad physics at the quantum level is nothing more than a load of speculative wank at this point.

>muh discrete quantized foamy spacetime, but its 2deep4u and I have no way to even come up with an experiment that would prove or disprove it
