A time-symmetric universe model and its observational implication

Симметричная во времени модель вселенной и ее экеперименталвные следтвия

Il Nuovo Cimento B (1971-1996)

Summary

A time-symmetric closed-universe model is discussed in terms of the radiation arrow of time. The time symmetry requires the occurrence of advanced waves in the recontracting phase of the Universe. We consider the observational consequences of such advanced waves, and it is shown that a test observer in the expanding phase can observe a time-reversed image of a source of radiation in the future recontracting phase.

Riassunto

Si discute un modello di universo chiuso simmetrico nel tempo in termini della freccia del tempo della radiazione. La simmetria nel tempo richiede la presenza di onde avanzate nella fase di ricontrazione dell’Universo. Si considerano le conseguenze osservative di tali onde avanzate e si mostra che un osservatore campione nella fase di espansione può osservare un’immagine rovesciata nel tempo di una sorgente di radiazioni nella fase futura di ricontrazione.

Резюме

Обсуждается симметричная во времени замкнутая модель вселенной в терминах стрелы излуения для времени. Временная симметрия требует существования продвинутых волн в фазе повторного сжатия вселенной. Мы рассматриваем наблюдаемые следствия таких продвинутых волн. Показывается, что наблюдатель в фазе расширения может наблюдать обрашенное во времени изображение источника излучения в будущей фазе повторного сжатия.
