Title. Insights into Messy Chemistry Related to Cosmology and Origin of Life Obtained by Employing State-of-the-art Computational Methods
Abstract. How life began on the early earth, as well as how small molecules and ions were first formed at the beginning of the universe are some of the biggest unsolved questions in science that have intrigued researchers over time. However, no clear answers have yet been received for researchers in the fields of cosmology, prebiotic chemistry, interstellar chemistry as well as astrochemistry. From previous studies, it has become clear that the creation of the universe and the origin of life are not the result of any single event. Rather, they are likely the product of highly complex or “messy” chemical processes. In this presentation, insight has been provided to explore some general and unsolved questions such as – which one was the first formed molecules after the Big Bang and how it was formed? How did the different life-building units form during the chemical evolution? etc. in the area of cosmology and prebiotic chemistry by employing state-of-the-art computational methods especially ab initio molecular dynamics (AIMD) with nanoreactor approach and further complete quantum chemical calculations with CCSD, RICC2, RIMP2 and DFT has been carried out.
Due to the present situation with the COVID-19 virus, seminars will be shared between Oslo and Tromsø by using the Zoom virtual meeting system.
