LEE CRONIN

Discovering the Origin of Life and Aliens using Complex Molecules

Lee Cronin is the Regius Chair of Chemistry in the School of Chemistry at the University of Glasgow, UK. Focusing on nanoscience and chemical complexity, he and his research group investigate how chemistry can revolutionize modern technology and even create life.

ABSTRACT

We have theorised that living things are unified by the ability to produce ‘unnatural’ or complex objects from molecules to space craft. By applying a new mathematical approach to finding complex systems, we are able to show that complex molecules cannot be formed by chance, and must be made by a living process or machine. In this talk I will explain how we have validated the method by monitoring existing efforts to make life in the laboratory in Glasgow and looking at the change in complexity of the molecules from the bottom up (chemicals to biology) as well as by going from the top down (biological cells to chemicals), see Figure1. I will also explain how this approach can be used to find life in the solar system and beyond.
