    Just read this article, which mentions that the abundance of gold in the universe "essentially defies explanation". I've never heard anything like this. I tried to learn more but haven't been able to find anything useful. Where can I find more info? Or feel free just to give details about the issue.

    There are a few points concerning gold in that when it is made in a supernova, it quickly condenses out (having a boiling point of 2,966.C) and having done so, gold is quite inert and does not casually bond with other elements, so stays as elemental gold rather than a compound. Gold is even heavier than lead so would be ejected further than light elements, so less likely to end up bound up in planets and moons with the lighter materials.

    Gold, being heavier than iron, is mainly formed in the rapid neutron capture process during supernovae. Its most abundant form as a result of this process however is a radioactive isotope which subsequently decays to nickel or cobalt or such.

    If you believe the likes of David Hudson, there is far more gold than we realize, but it's in it's monatomic state.

    There was the idea that a supernova should expand out a bit like a mass spectrometer, separating elements by mass.
    Gold would be the last element to arrive in a new system, potentially after stars & planets had started to form. This would make gold more abundant in the upper layers of objects & the remaining debris.
