  • Complex Chemical Networks in Astrobiology
    NAI 2010 Montana State University Annual Report

    Many of the building blocks for prebiotic chemistry form in dark molecular clouds — dense regions of interstellar gas and dust from which stars and planetary systems are also born. Sophisticated chemical models have been developed to understand the complex network of reactions that can convert simple precursor molecules to the complex organics that are often found in meteorites and comets. We have begun to apply the tools of network theory — a branch of mathematics that studies interconnected complex systems from cellular metabolism to Facebook — to gain more insight into the structure of these interstellar chemical networks. This approach allows us to make comparisons between complex chemical networks in biology, astronomy, and planetary science, searching for unifying general principles and critical differences between living and non-living systems.
