Scientists have created a new tool which could help humans find alien life in the universe. The method, called Assembly Theory, can identify complex molecular signatures to determine the likelihood of it developing through life rather than by chance, say researchers at the University of Glasgow. The team, who worked with collaborators at Nasa and Arizona State University, used highly technical methods to break down particles and count the number of unique parts, giving analysts a clearer idea of how it came into being. Lead scientist, Professor Lee Cronin, Regius Professor of Chemistry, said Assembly Theory is the “first falsifiable hypothesis for life detection”.
