Ran the numbers. The LHC would break even if the price of gold was $48 trillion trillion per ounce.

Only if the LHC doesn't quire gold to operate. If you're using ICs and components that have some gold in them and they need maintenance, you consume more than you produce.

  • Well, except for in particle accelerators, stars, and supernovae, atoms are never created or destroyed, so if they're creating gold, it's here for good.

    • Except that everyone with a fusor can feed the gold atom a neutron which converts it to unstable Au-198 that decays to mercury. Fun times when you can (theoretically) transmute gold to mercury with stuff you can order on the internet.

    • Just saw this idea recently -- to add to your list: "Magnetars’ strong flares forge gold and other heavy elements" https://earthsky.org/space/strong-flares-magnetars-forge-hea... "After black holes, neutron stars are the densest objects in the universe. A neutron star forms when the core of a massive star collapses during a supernova explosion. Intense gravitational forces compress the core, reducing most of its elements to subatomic particles called neutrons. And magnetars are neutron stars with intense magnetic fields. On April 29, 2025, astronomers said a powerful flare unleashed by a magnetar, named SGR 1806–20, created large amounts of heavy elements including gold, strontium, uranium and platinum. They think magnetar flares could produce as much as 10% of the heavy elements in our galaxy."

      I have no clue about this stuff, but don't black holes also change matter... somehow? I mean, with all that gravity and stuff, crazy things must happen in there, right?

My high school science teacher(Brother Quinn in the 80s) always said it was possible, although rather expensive, now I know how much - thanks.

hard to compete when stars do it for free

  • The stable isotope of gold is produced by the collision of two neutron stars, which is unlikely to happen in our stellar vicinity any time soon.

    • This is something I don't get - solar system is say 5 billions years old (a bit less I know). Universe is roughly 13 billions, and our Milky way almost the same.

      What this means is that there must have been quite a few collisions of such before solar system formed, to produce so much of heavy stuff we see in our planet, no? Stars can produce only up to Fe in normal way. Yet it seems such collisions are very rare, and its not like during collision half of the mass converts to a golden blob (or more like atomic mist spreading away at fraction of c).

      I know 8 billions of years is a long time, and gold once fused ain't breaking apart to H or He anytime soon, but still it feels like our planet should have way more basic atoms and not all of those rare fused oned. What about super/hypernovae?

    • We don't have to wait for any new collisions. Plenty have already happened and left their debris on the "cosmic floor", so to speak.

On the other hand, it's only doing this accidentally, right? It could probably be optimized further if the goal were just transmutation. Who knows, maybe we could get all the way down to only 10 trillion per ounce! /s
