Deuterium Signals in 3I/ATLAS Spur Fusion Talk, Not Alien Proof
New JWST analyses of the interstellar visitor 3I/ATLAS reveal unusually high deuterium in its gases, suggesting formation in extremely cold, metal-poor regions billions of years ago. Two Nature Astronomy papers argue the isotope pattern could be a natural relic rather than evidence of alien technology, while Avi Loeb questions the interpretation and notes deuterium as potential fusion fuel. Overall, the findings point to a natural origin and do not prove extraterrestrial engineering.
