Really. Oooookay. What about common objects like potatoes and chickens?
Do you think there might be a reason why all microwave ovens are
basically metal boxes? Why there is a metal mesh on the door glass? Why
microwave repeaters (and satellite dishes) are made of (or coated with)

And it is true. And it is an excellent reason (one of several) to not
put metal in microwaves. The fact that it can damage the metal articles
or even the microwave oven itself is probably a better reason.

No. But you do need to understand quite a lot more than "nothing", which
is what Jean (?) was saying.

Dipoles/Otto cycle = too low. Nothing = too high. Just rules = nothing.
I'm done now.
