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. (This talk will have been held in german language two weeks beforehand!)
