Have the scientists ever considered the possibility that Earths inner core could be the coldest zone of the planet?
A possible theory about the interior of the Earth suggests that the Inner Core is a huge bubble of solid oxygen mass (magnetic-paramagnetic) floating in the center of Outer Core ( liquid oxygen). The inner core is the coldest zone of the planet. The innermost core is nothing else than an empty space of 1326 kilometers of diameter in the center of Inner Core. Reply It is a clever theory, but it fails in several fundamental ways: (1) Heat always flows from higher temperature to lower temperature–that is established in many experiments, and in many kitchens. If your refrigerator is disconnected, its inside will gradually warm up. We know the average temperature of the surface of the Earth is near 20 deg Centigrade or about 300 deg absolute. If we dig down, it always gets hotter, and the heat flow from the inside out has been measured. Gold miners deep in South Africa, for instance, endure great heat. Thus if the inside of the Earth were solid oxygen, it would quickly melt and evaporate.
