CERN Scientists Briefly Turn Lead into Gold in LHC—Did They Just Achieve Alchemists' 400-Year-Old Dream?

Well, it seems that the CERN scientists have kind of achieved the alchemists' 400 - year - old dream, but with some big catches.​

For centuries, alchemists in the 17th century had this wild idea of turning common lead into precious gold through chemical means. However, they didn't succeed because lead has 82 protons and gold has 79 protons. The difference in the number of protons means that a simple chemical reaction won't do the trick. Chemical reactions mainly involve the outer electrons of atoms, not the protons in the nucleus.​

But the scientists at CERN, at the particle physics laboratory near Geneva, Switzerland, used a totally different approach. They used the Large Hadron Collider (LHC), which cost billions of dollars. In the LHC experiments, they made lead ions collide. Here's the key: when two lead ions just "brush past" each other instead of having a head - on crash, the strong electromagnetic fields around the ions create an energy pulse. This energy pulse is so powerful that it makes the oncoming lead nuclei eject 3 protons. As a result, the lead, with 82 protons, is transformed into gold, with 79 protons.​
The ALICE experiment at the LHC was able to screen out these cases of transmutation from the collision debris. According to the analysis report released by the research team, during 2015 - 2018, the LHC collisions produced 86 billion gold nuclei. But here comes the letdown. The total mass of these gold nuclei is only about 29 picograms, which is one - trillionth of a gram. And these high - speed and unstable gold nuclei only exist for about 1 microsecond on average. After that, they either hit the experimental device or decay into other particles. Also, gold is produced whenever the LHC does lead - beam collisions, but only the detector configuration of the ALICE experiment can capture this process.​

Now, it's not all bad news. A physicist from Stony Brook University in New York, Jiangyong Jia, pointed out that another device at CERN called the Super Proton Synchrotron (SPS) had observed the transformation of lead to gold between 2002 - 2004. But this new experiment at the LHC has a much higher energy, which greatly increases the probability of producing gold and gives much clearer results.​

The CERN researchers have no plans to turn this into a side business of making gold. Instead, they believe that a better understanding of how photons change atomic nuclei can help improve the performance of the LHC. Jia also emphasized that understanding such processes is crucial for controlling the quality and stability of the beam.​

So, in a way, the CERN scientists have achieved the transformation of lead into gold, just like the alchemists wanted. But it's a very short - lived and extremely expensive process. It's not a practical way to get rich by making gold, but it's a huge scientific breakthrough that helps us better understand the fundamental laws of the universe.

Okay, so did CERN actually pull off the ultimate alchemist flex? Short answer: Kinda, but not in the way you’re imagining. Here’s the wild science behind it—and why you won’t see physicists selling LHC-made gold bars anytime soon.

First off, let’s be clear: ​​this isn’t medieval cauldron magic​​. CERN’s Large Hadron Collider (LHC) smashed ultra-fast lead ions together at near light-speed, and in rare ‘grazing’ collisions (not head-on crashes), the insane electromagnetic forces ripped off 3 protons from lead nuclei (82 protons)… turning them into gold (79 protons). The ALICE detector spotted these ultra-short-lived gold nuclei—​​860 billion of them​​ between 2015-2018! But here’s the catch: they existed for ​​about a microsecond​​ before disintegrating or hitting the detector. Total mass? A pathetic ​​29 picograms​​ (that’s trillionths of a gram).

Now, why is this a big deal? Because:
1️⃣ ​​Proton Yeeting 101​​: It proves you can transform elements by force—just not chemically (sorry, alchemists). The energy required? Astronomical. The SPS accelerator saw hints of this back in 2002, but LHC’s higher energy made it blatantly obvious.
2️⃣ ​​Side Hustle? Nope​​: Even if CERN scaled this up (they won’t), producing one gram of gold would cost ​​quadrillions​​ in electricity. Bitcoin miners would laugh at the inefficiency.
3️⃣ ​​Real Goal​​: Understanding how photons mess with nuclei helps improve beam stability for future LHC runs. As physicist Jiangyong Jia notes, this is crucial for precision experiments.

So yes, CERN technically ‘made gold,’ but it’s more like a cosmic party trick than a get-rich scheme. The real win? Flexing on 17th-century alchemists with physics receipts."
