Where Does Gold Come From?

The iron in our blood or the oxygen that we breathe all formed during chemical reactions inside of a #star, but when it comes to heavier elements such as #gold, a different process might be at play. UC Santa Cruz's Enrico Ramirez-Ruiz has his own theory about where gold comes from in the universe and it may have to do with the spectacular explosions of #supernovae.

A Jupiter-sized mass of gold? Incredible!

[HenningRogge]

I am not quite sure what to think about the video...

First it starts with "we have no idea where heavy elements come from"... which in fact is wrong, because the "standard model" for creating elements heavier than iron is the same it was a decade ago. Production during the core collapse of a star into a supernova. This is a basic fact they teach you at university in the first year of Astronomy.

The idea about creating heavy elements in other high-energetic events like the merger of neutron stars is interesting, but the theory feels a little bit hollow. The major problem I see is that a neutron star is mostly neutrons (except on the surface), which makes the production of heavy elements more difficult than in a supernova of a massive star (which happens when the fusion of the star produces elements up to iron). It would first take a lot of proton creation through beta decay or similar processes.

The phrase "it produce a Jupiter mass of pure gold" is also misleading at best... IF heavy elements would be produced in neutron star mergers, then it would be a mixture of all kind of heavy elements with a high proportion of "less heavy" elements... which doesn't sound like "pure gold" for me.

"Still don't know where Gold comes from" -- SUPERNOVAS. The explosion of a star creates high frequencies of both fusion and fission reacts which result in rare elements that cannot be created in any other way. That matter is then strewn about the cosmos.

I love it when the internet is a source of scientific knowledge, even if it is based on theoretical astrophysics. This should be required info provided to the youth, and not the latest fashion or celebrity drama

[sherbang]

What if its always the same element, changing, shifting, appearence, all the way through the periodic table and beyond ?

Like a spiral going round, each octave, from gas to solid and all the way in between, forever going ? :)

[nuclearthreat]

are there more videos about the binary stars touching and creating this?

[sdbullion]

190, 000 tonnes or just over 6.1 billion ounces of gold have been recovered by us humans thus far here on Earth.

[Boomer]

Gold is created when a star goes supernova

[voodoo]

Break me off a piece of that Jupiter size gold!

[IKingRonin]

so your saying my gold coin fell from space?

[askarana]

After listening to this guy's voice, my throat hurts

[taraconstruction]

So Basicaly Gold should be more Pricy than the Diamond. Because earth cannot make it, so it basically Alien stuff.

[LuisLopez-cqsl]

Humans in the far future will be able to harvest this stats

[KrisBendix]

LHC does that too. :p Now think about it. For billions of years only way for elements to be 'born' was mainly from stars. And then this life thing happened (no matter how), and now life (human) can do it too. It's God-Like! :D

[tohdotohka]

gold is produced by the elements of G O L and D
