Solution of the Horizon Problem — •Philipp Schöneberg¹ and Hans-Otto Carmesin^1,2,3 — ¹Gymnasium Athenaeum, Harsefelder Straße 40, 21680 Stade — ²Studienseminar Stade, Bahnhofstraße 5, 21680 Stade — ³Universität Bremen, Fachbereich 1, Postfach 330440, 28334 Bremen

In the early universe, the density was very high. As a consequence, there occurred gravitational instabilities and dimensional phase transitions. These have been derived in three very different physical systems, see Carmesin, Hans-Otto (2021): Quanta of Spacetime Explain Observations, Dark Energy, Graviton and Nonlocality. Berlin, Dr. Köster Verlag.

Using these phase transitions, the light horizon as a function of time R(t) can be calculated, ranging from the Planck length to the present day value. With it we derive the solution of the horizon problem.
