I don't know anything about geology or the Earth's core, but I do know that radioactive heating is still a one-way process. Entropy exists, and even if the short-term result is heat positive, the end result is always heat death.
- Infernal 8y agoYes, this was the question I was trying to get at. The linked wikipedia article above answers it though - energy from the sun only penetrates 10's of meters into the earth's crust, so for all intents and purposes the interior of the earth, considered as a closed system, has no energy inputs.
- hammock 8y agoNo inputs, but it is not "simply hot and always cooling." Even as a closed system, it is generating new heat
- kryogen1c 8y agoI'm not sure what your point is, so you might consider this splitting hairs. Heat is not being generated, it's being converted. That conversion requires a source that will run out. It will continue to be warm for any meaningful timeline to a human, but it is not infinite and will end in heat death.
