'projecting' energy is kinda easy... 'sucking' energy is difficult
I've been wondering this for my entire life
a can of soda can cool faster in the freezer for ~30 min.
some people suggest adding an insulated sleeve.
i also use freezer to cool down coffee quickly.

yeah, not only microwave but heater in general... but reversed, i asked myself that question for a long time, i mean we pump an electricity into the wire and we get heat, why not reverse? why we can "magically" get heat from electrons but to get something cold we need to pump the heat elsewhere, like microwave basically make atoms vibrate generating heat, would be cool to be able to generate some field that makes atoms stop
Friction mostly. And smallnforces that act like friction in ways I am not smart enough to explain
i would think not. unless waves can be tuned to cancel out background radiation, but that would only stop it from heating up more.
Given how much about science we still have to learn, I would say it is a distinct possibility. If you want something cheap and easy to use like a microwave to do this though, I highly doubt we'd see that possible for the next 30-40 years at minimum.

They trial'd something similar on the snowpeircer train instead of treats like ice cream for good behaviour they froze your arm off for being naughty lol
It's a good job they didn't have that when I was at school because I'd be just a head and torso now lol
