My point is that this is not about the age of the Earth, it's about why the core is hot so as I said, somewhat relevant, but not directly.


Seems the consensus is that most (90+%) is due to radioactivity with a bit due to friction and a bit left over from the formation.

Would be very cool (pun intended) if we could somehow capture this heat and use it for your energy needs -- certainly lots of work going on already....
