This makes me wonder about something. Currently, it is believed that all the elements on the earth were created in supernova. Is it possible that this transmutation may happen naturally, and at least some of our heavier elements came to be on their own in 4.5 billion years?
Whatever heavy elements were in our neighborhood 4.5 billion years ago were mostly sucked up by the Sun and outer planets. The ones like gold and uranium, lead, etc. probably sank into the molten core of the earth when it’s surface was still molten, only to be diffused into the mantle and eventually the crust through volcanic action over the epochs.........
