the reason magnets point north and south is because in the middle of the earth is a 2500 mile diameter sphere of pure liquid iron. the pickme catch-all element on the periodic table which is resonant atomically in all the ways, and requires outlandish quantities of energy to change those atoms, which are perfectly fine to stay that way forever, into anything else. > but it rusts. no, the atoms of iron just disconnect from each other, and last for eternity, the brown growth called rust is just weaker atoms, hydrogen and oxygen wanting to hug it down into a slurry goop. heat the liquid rust to get rid of the other elements, and you're left with the same quantity of iron that you started with. iron is eternal unless you put it into cern particle accelerator.
