Insightful exact three-dimensional representation of curved spacetime — •Hans-Otto Carmesin — Athenaeum, Stade — Studienseminar Stade — Universität Bremen, Fachbereich 1

Astrophysics, general relativity and curved spacetime motivate students. However, so far, it was not possible to represent three-dimensional curved spacetime in an exact manner. But now, such an exact and clarifying representation is possible: From the usual algebraic description using a metric tensor, changes of lengths and of volume are derived. These are represented with help of transparent plastic material in a three-dimensional and exact manner.

This representation is realistic, as the above changes of lengths can be measured. It is valuable, as students can derive the cosmological constant Λ, though Einstein was unable to derive Λ from his ingenious general relativity. Perlmutter (1998) measured that value of Λ.

Similarly, deriving & using the dynamics of the above volumes, students can unify relativity, gravity and quanta.

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.
