We present a solution of the horizon problem. For it we derive an answer to the following question: How was light able to thermalize the early and rapidly expanding universe? We apply the dimensional transitions that took place in the early universe as a consequence of gravitational instabilities (Hans-Otto Carmesin (2020): The Universe Developing from Zero-Point Energy - Discovered by Making Photos, Experiments and Calculations. Berlin: Verlag Dr. Köster). In particular, we apply the time evolution of the light horizon arising as a consequence of the combined dynamics of the Friedmann Lemaitre equation and of these dimensional transitions. We analyze various models for the matter and energy in the early universe. The project is presented as an example for teamwork in an ensemble of projects in the field of quantum gravity that are carried out in a research club at our school.
