Broadening the Search for Life Beyond Earth: From Project Hail Mary to Diverse Biosignatures and Technosignatures

To the point

The film and scientists like Cole Mathis, Amirali Aghazadeh, Chris Impey, Macy Huston, and Jason Wright urge that life beyond Earth could use different chemistries, so searches should go beyond Earth-like water and the Goldilocks zone to look for signs such as metabolism, mineral-driven complexity, and technosignatures, while ruling out nonbiological explanations and demanding strong evidence because Earth biology is only one possible blueprint.
