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