A Model for the Dynamics of Space — •Hans-Otto Carmesin — Gymnasium Athenaeum, Stade — Studienseminar Stade — Universität 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 the Cosmic Inflation by gravitation and quantum physics (Carmesin: Vom Big Bang bis heute mit Gravitation, Model for the Dynamics of Space, 2017). We apply fundamental constants only, namely the constant of gravitation G, the velocity of light c and the Planck constant h. We discover a sequence of dimensional phase transitions at critical densities and achieve excellent quantitative agreement with observations. A learning unit has been devised that focuses on problem based learning and research based learning. The unit has been applied in a Jugend forscht club. Experiences from teaching are presented.
