Where did the Universe find its gold?

Whirling “Collapsar” stars is the answer, whatever that means…

Most of the universe’s gold, uranium and other heavy elements are generated from rapidly whirling collapsing stars, a new study finds.

The universe’s three lightest elements — hydrogen, helium and lithium — were born in the earliest moments of the cosmos, just a minute or so after the Big Bang. Elements up to iron on the periodic table were mostly forged later, in the cores of stars.

However, the way in which elements heavier than iron on the periodic table, such as gold and uranium, were created has been a long-standing mystery. Previous research suggested a key clue: atomic nuclei often needed to absorb neutrons rapidly, a phenomenon known as the “r-process” for short.
