If 3I/ATLAS isnt an alien probe, why is it silent on radio signals but rich in methane from another star system?

If 3I/ATLAS isnt an alien probe, its discovery may be even more important. Scientists detected no radio signals from the interstellar comet despite an extensive search for technosignatures. Instead, the James Webb Space Telescope found unusually high methane and carbon dioxide levels. Those findings suggest 3I/ATLAS formed in a vastly different star system. More than a space mystery, this methane-rich interstellar object acts as a cosmic time capsule, carrying rare clues about planetary formation, comet chemistry, and the hidden diversity of worlds beyond our Solar System.
