1. Which is more useful, the Sun or the Moon? The Moon is more useful since it gives us light during the night, when it is dark, whereas the Sun shines only in the daytime, when it is light anyway.Although Gamow was -- presumably -- saying this as a joke, it's entirely in accord with Genesis:
GEORGE GAMOW (inscribed in the entry hall of the Hayden Planetarium, New York City)
1:3 And God said, Let there be light: and there was light.So I'd say that Gamow's statement is logical in form. It is, however, based upon the premise that the Genesis model is a scientifically accurate description of day and night and the function of the sun and moon.
1:4 And God saw the light, that it was good: and God divided the light from the darkness.
1:5 And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
[Thus, there was light before the sun, as Gamow assumes.]
1:16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.
1:17 And God set them in the firmament of the heaven to give light upon the earth,
1:18 And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.
1:19 And the evening and the morning were the fourth day.
