GOLD – it’s been the treasure of kings, the sparkle in wedding rings, and the subject of myths for thousands of years.
But the real story of gold could be even more extraordinary than anything humans ever imagined.
It is said to have begun long before Earth existed, in some of the most violent events the universe has ever seen.
To understand gold, some scientists say we need to wind the clock back 13.8 billion years to the Big Bang. They say that in that first instant of creation, the universe formed the simplest elements – hydrogen, helium and a little lithium.
But gold was nowhere to be found. It needed conditions far more extreme than even the Big Bang could provide.
Millions of years later, the first stars were said to be born. These giant stars burned hot and fast, turning light elements into heavier ones – carbon, oxygen, silicon and iron.
But once a star produces iron, it can’t give off energy anymore. It collapses under its own weight and explodes as a supernova, scattering its contents across space.
Now imagine something even more dramatic. Picture a star like our Sun crushed into a sphere only 20 kilometres wide – a neutron star.
Sometimes two neutron stars orbit each other for millions of years, gradually spiralling together until they finally collide.
The explosion that follows is called a kilonova – even more powerful than a supernova – and it is in this moment of unimaginable force that gold is created.
Along with platinum and uranium, gold is forged in the split-second violence of colliding neutron stars. It’s as though the universe itself is minting treasure.
Scientists believe a single neutron star collision can produce amounts of gold equal to several Earths.
Over billions of years, this cosmic gold dust drifted through space until it settled into the cloud of material that eventually formed our Sun, our planets, and our own Earth.
Every gold ring, every nugget mined from Australian soil, carries atoms born in a stellar collision long before our planet came into being.
So the next time you see gold – in a ring, a coin, or even a shareholders’ report – remember its incredible journey.
It isn’t just a metal. It’s a survivor of cosmic violence, a fragment of the universe’s most dramatic moments. A tiny piece of a long-dead star.
Interesting times may lie ahead for gold here on Earth as well. Some commentators claim the US could revalue its official gold price from the long-standing figure of $42.22 to as much as $4000.
Whether that happens or not, gold’s cosmic story reminds us why it has always held such a powerful grip on human imagination.
