On Phase Transitions in the Early Universe — Hans-Otto Carmesin^1,2,3 and •Philipp Schöneberg¹ — ¹Gymnasium Athenaeum, Harsefelder Straße 40, 21680 Stade — ²Studienseminar Stade, Bahnhofstr. 5, 21682 Stade — ³Universität Bremen, Fachbereich 1, Postfach 330440, 28334 Bremen

We summarize a covariant quantized field equation for the elements of spacetime. Using that equation and the droplet model, we derive phase transitions in the early universe. Moreover, we compare with three other derivations of these phase transitions using

(1) the van der Waals concept

(2) a connectivity of space concept,

(3) a bose gas.

We report about corresponding lessons and experience in a research club.
