Students Learn to Solve the Cosmological Constant Problem — •Hans-Otto Carmesin — Athenaeum, Stade — Studienseminar Stade — Universität Bremen, Fachbereich 1

Electricity and volumes are omnipresent. However, the theory of quantum electrodynamics predicts an energy density of the electromagnetic field uQED that is a factor of 10122 larger than the observed energy density of volume uvol, this is the cosmological constant problem, CCP. uvol is essentially the observed dark energy. We show how students can solve it in an exact and elegant manner: Based on the usual algebraic structure of Einstein’s ingenious general relativity, the dynamics of volume are analyzed & derived. With it, the energy density uvol is derived and identified as a kinetic energy density. The potential energy density of uvol,pot compensates uvol and implies energy conservation during the expansion of space. Moreover, the volume dynamics show that uQED is compensated by its potential energy density uQED,pot, this solves the CCP. Moreover, the Casimir force is derived.

Our results are in precise accordance with observation and fully derived from physical principles [1,2]. Experiences from teaching in research clubs and general study courses at a university are presented.
