How does Metal Expansion effect things here on Earth
microwaves, ovens, car engines, guns,etc.?
Do you mean because of heat?
Well if you do, these items are manufactured so that the expansion of
the metal due to heating under normal operating temperatures will not
distrub the function of the manufactured item. The classic example, is a
bridge, which has joints that can expand when the temperatures are hot
during the summer and contract during the cold winter months. Without
these "tricks" the steel of the bridge would become stressed which leads
to metal fatigue and failure.
