Summary
The usual expression for the gravitational red-shiftz is calculated exactly in both the standard and isotropic forms of the Schwarzschild metric. The differing results are found to be meaningless and metric dependent until they are put in terms of quantities directly observable from Earth. The importance of expressing physical quantities in terms of observables is stressed.
Riassunto
Si calcola esattamente la consueta espressione del red-shift gravitazionale nella forma standard e in quella isotropa della metrica di Schwarzschild. I risultati differenti risultano essere privi di significato e dipendenti dalla metrica a meno che non li si ponga in termini di quantità direttamente osservabili dall terra. Si pone in evidenza l'importanza di esprimere le quantità fisiche in termini di osservabilità.
Резюме
Точно вычисляется обычное выражение для гравитационного красного смещенияz и в стандартной и в изотропной формах метрики Шварцшильда. Найдено, что отличающиеся результаты лишены физического смысла и зависят от метрики, пока они не выражены через величины, непосредственно наблюдаемые с Земли. Подчеркивается важность выражения физических величин через наблюдаемые.
