Last week, Marathon Fusion, a San Francisco-based energy startup, submitted a preprint detailing an action plan for synthesizing gold particles via nuclear transmutation—essentially the process of turning one element into another by tweaking its nucleus. The paper, which has yet to undergo peer review, argues that the proposed system would offer a new revenue stream from all the new gold being produced, in addition to other economic and technological benefits.

any particle accelerator can do that just incredibly slowly.

Alchemy of that sort has been doable for generations, it's just WILDLY impractical!

Currently many orders of magnitude more expensive than just buying an equivalent amount of gold, but makes me wonder what the future might be capable of with those proofs of concept.

Science circling back around to alchemy is an interesting thought.

I admit, it wasn't on my 2025 bingo card, either.
