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.
