Gold is certainly one of the most alluring natural resources, but just how did we come to find it? Come with us on a journey through space and time, from meteors to prospectors from the Wild West, to find out more about this mesmerising metal.

Taken from 'Colour: The Spectrum of Science' (2015).
Just 15 colours tell the entire story of Earth, life and scientific discovery. This series explains how each of these colours occurs, unlocking the mysteries of nature and the forces that underpin the Universe itself. More than any other planet, the Earth is awash with colour. With its flowers, oceans, rainbows and vast array of animal life, our planet stands out from the blackness of space as a multi-coloured jewel. Our eyes allow us to experience colour as an explosion of vibrant wonder. Colour: The Spectrum of Science examines this miracle of nature, and travels across the world to discover what makes our planet's palette unique.

as indian the universe was created when a lotus grew out of lord vishnu stomach, then separated into three parts. we indians believe this becase we have scientific proof of panchagavya concept. According to same teachings, cow is holy because a thousand god live inside it. This is why cow byproduct is holy and clean (natural antiseptic). And why we indians use cow dung soap, toothpaste, etc.

After watching this short entertaining video I was actually going to comment the same, personally I believe the sun is partially gold but some would say why isn’t gold found in the moon or mars? Again my personal belief with the inter connected planetary system earth having the strongest fields might attract particles rather than other planets, I’m in Victoria Australia and surrounded by gold fields one of the richest in the world some prospectors find clean round nuggets pebble to stone size just sitting on top of the surface looking at you and they look like meteorites with the smouldering dimples I also believe earths core has something to do with gold

I find it fascinating that the woman is suggesting how precious gold is, yet she is objectively much more precious than it considering gold is sprinkled across the universe, yet we still haven't found life, let alone intelligent life. And yes, I think she's beautiful lol
Gold is one of the many metals found in human blood too

One thing that should interest a lot of people is that during the formation of our solar system, heavier elements were attracted to gravitational forces as soon as they could... Don't be surprised if one day we find Mercury and Venus to be far wealthier than Earth in their gold possessions. ✨️
Gold and its importance is always a good topic to talk about. The human fascination with Gold is very interesting.

So get our there and get yours! Just don't mind the costs of storing and securing it too much. I mean, that is after you mine or harvest and transport it. And of course secure those two phases as well.
Not great wording. Nowhere is it stated that gold is inert, you can repurpose it at infintum, hence gold is not a critical mineral. I also object to “geology and water processes”.
So ELI5 is that gold comes from space, gets concentrated through "geological processes", then washed out by water? That's the most *unspecific* "explanation" you guys could give.

I ever heard a story about the origin of gold in hinduism where Shiva was meditating and after finished his meditation he missed Parvati so much which made his semen spurted and it fell to some places on earth, and after that those semens turn into gold.

Not from what I’ve read. Our star the Sun isn’t massive enough to make heavier elements. I could be wrong, but I don’t think our Sun can’t make iron, let alone anything heavier. That said, I’m sure there is gold in the overall makeup of the Sun just as there is here on Earth. In the beginning stars were made of 100% Hydrogen, but since that beginning, there have been many larger stars who over time have been massive enough to make iron and heavier elements as well. One more thing that others have posted….it is now believed that some heavier elements found in our solar system today were created in more rare and much larger stars. If a gene were to grant me three wishes, one of my choices would be for a couple Kg of Californium, which would be worth much more than all the Gold on Earth! It’s all about what humans want, and how much they are willing to pay for something that is completely useless to most humans. I mean, I never wear my gold wedding ring anymore. It sits in a drawer in its original jewelry box. I’ve never once ever cheated on my wife and I never will (after several decades of living happily ever after, I still think she is the cutest, sexiest chick I’ve ever seen!). She never fails to make my motor run! So why bother wearing a ring which could in fact help kill me if I were to ever come in contact with a high voltage wire-line. When we got married, we both spent huge sums of money for each other’s ring (hers was scary expensive because that is just what everyone did back in those days). But since then neither of us has worn our rings other than for special occasions.

Scientists believe all the gold on Earth formed in supernovae and neutron star collisions that occurred before the solar system formed. In these events, gold formed during the r-process. Gold sank to the Earth's core during the planet's formation. It's only accessible today because of asteroid bombardment. (Found in quartz from asteroid collisions)
We have no idea how gold arrive on Earth. It's all a speculation! Maybe it seem logic or beautiful, but we have NO idea. I remind you: - scientific theory is scientific if and only if it fulfils 3 conditions at once: 1. it predicts something (explain). 2. it can be tested in at least 2 different ways in a reasonable time 3. repeated test yields the same results. Please test your explanation and give me the same results all over again! Thank you!
