The Twin Paradox and its resolution

Lecture in English

Boris Lohner (Munich Public Observatory)

FRIDAY, 24 July 2026, 8 p.m.
Venue: Volkssternwarte (Munich Public Observatory), Gisela-Stein-Str. Ecke Ludwig-Jung-Straße, 81671 München

Explanations of the twin paradox sometimes give the impression that special relativity is defective and that this „defect“ requires general relativity to be „repaired“ – or give the impression that time dilation is not real but a mere effect of observation. In this talk it is shown how the twin paradox can be resolved in a consistent way while staying within special relativity.

If skies are clear, guests are invited to visit the rooftop observatory after the talk.
