A Computer Simulation of Cosmic InflationHans-Otto Carmesin1,2,3 and •Lennert Sprenger11Gymnasium Athenaeum, Stade — 2Studienseminar Stade — 3Universität Bremen

From the Cosmic Microwave Background CMB the flatness problem and the horizon problem arose. An extraordinarily rapid increase of distances in the early universe, the Cosmic Inflation, was proposed as a possible solution, whereby suggested mechanisms for such an increase have been criticized (Steinhardt, 2011). We apply a theory that explains Cosmic Inflation by an extended Friedmann Lemaitre Equation combined with an energy term (Carmesin: Vom Big Bang bis heute mit Gravitation, Model for the Dynamics of Space, 2017). We investigate various questions by performing computer simulations. We observe a sequence of phase transitions that cause an extraordinarily rapid increase of distances. Our findings are in excellent quantitative agreement with observations of the CMB. Thereby the theory depends on first principles and the fundamental constants G, c and h only and we apply no fit in particular. We present the development of the project in the framework of a Jugend forscht club.
