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 u_QED that is a factor of 10¹²² larger than the observed energy density of volume u_vol, this is the cosmological constant problem, CCP. u_vol 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 u_vol is derived and identified as a kinetic energy density. The potential energy density of u_vol,pot compensates u_vol and implies energy conservation during the expansion of space. Moreover, the volume dynamics show that u_QED is compensated by its potential energy density u_QED,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.
