Relatively complicated? Teaching general relativity at different levels — •Markus Pössel — Haus der Astronomie und Max Planck Institut für Astronomie, MPIA-Campus, Königstuhl 17, 69117 Heidelberg

Can a bowling ball in a rubber sheet properly represent Einstein's description of gravity? Is space really expanding in an expanding universe? In an interferometric gravitational wave detector, do light waves play the role of a ruler?

Simplifications and analogies are unavoidable whenever teaching Einstein's theory of general relativity to a wider audience, such as undergraduate students, high school students, or the general public. The talk presents examples for such simplifications and analogies at different levels, including a critical discussion of misleading examples and potential pitfalls.
