When humanity finally detected the collision between two neutron stars in 2017, we confirmed a long-held theory - in the energetic fires of these incredible explosions, elements heavier than iron are forged.
And so, we thought we had an answer to the question of how these elements - including gold - propagated throughout the Universe.
But a new analysis has revealed a problem. According to new galactic chemical evolution models, neutron star collisions don't even come close to producing the abundances of heavy elements found in the Milky Way galaxy today.
"Neutron star mergers did not produce enough heavy elements in the early life of the Universe, and they still don't now, 14 billion years later," said astrophysicist Amanda Karakas of Monash University and the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) in Australia.
"The Universe didn't make them fast enough to account for their presence in very ancient stars, and, overall, there are simply not enough collisions going on to account for the abundance of these elements around today."

"We can think of stars as giant pressure cookers where new elements are created," Karakas said. "The reactions that make these elements also provide the energy that keeps stars shining bright for billions of years. As stars age, they produce heavier and heavier elements as their insides heat up."
To create elements heavier than iron - such as gold, silver, thorium and uranium - the rapid neutron-capture process, or r-process, is required. This can take place in really energetic explosions, which generate a series of nuclear reactions in which atomic nuclei collide with neutrons to synthesise elements heavier than iron.

“So how do I turn lead into Gold? (PB>AU)”
You load your gun, you rob a bank. Something along these lines. (Look out when the lead comes back your way!)
These discuss a 10th century African way to remove impurities in refining gold! (Using recycled glass!)

This all I need to know: Book of Genisis,..God’s creation of the Earth, water, rivers, gold.....”10And a river went out of Eden to water the garden; and from thence it was parted, and became into four heads. 11The name of the first is Pison: that is it which compasseth the whole land of Havilah, where there is gold; 12And the gold of that land is good: there is bdellium and the onyx stone. ...”
Do the stars get heavier because they collided with a high fructose corn syrup star?
When a particular branch of science becomes “settled” it is no longer science...it’s religion.
Simple scientific answer: The Big Bang.
Simpler REAL answer: God.
And the two are not mutually exclusive.

“The True Origins of Gold in Our Universe May Have Just Changed, Again”
Stupid headline too. How could the “true origins of gold” change? Did gold go back in time and re-originate itself?
“Theory of origins of gold ... may have just changed, again.” would have been a lot better.
A lot of science is still not settled.
Aliens aren’t on the gold standard. They use “Latnium”. At least in the Star Trek universe.
That is what I believe too. Others are free to their belief as well.
It's right there, along with the Ark:
By the way, at today's prices, gold is worth about $50 million per ton, meaning Solomon's gold, if he had, say, ten tons, would be worth $500 million today -- a substantial sum.
The total of all the gold in all the world's banks & vaults today is around 200,000 tons worth around $10 trillion, with a "t".
