"...new data from NASA's Gravity Recovery and Interior Laboratory (GRAIL) spacecraft..."

Oh Very nice!



If the mantle is molten and the collision was such that you are finding signs under africa and the pacific, then it seems logical that a lot of it is going to be mixed. Perhaps certain metals that would be more foreign to the first earth have properties that are coalescent and easier to identify after such a long period of time.

“first earth”

I like that...has a ring to it.

“I am from First Earth.”
