Marathon Fusion, a San Francisco-based fusion start-up has said that it turned mercury into “real, stable gold,” beating CERN’s record by a factor of 10. The San Francisco startup announced the result on social media platform X on October 21. However, the company has not disclosed how much gold its experiment produced, leaving questions about the scale and commercial potential of the claimed breakthrough.
The claim has revived an age-old question: could science make gold in a lab and eventually make the precious metal less scarce?
