Hanumān: The scientists, they also say that in twenty-five years from now, whatever they contrive to do they will not be able to feed all the people of this planet. They can try to . . .
Prabhupāda: At the end of it, everything has changed; therefore they can speak.
Hanumān: Oh, yes.
Prabhupāda: So they have got this loophole. They can speak any nonsense. They will adjust, "Oh, it has changed." That's all.
Woman devotee: One time they believed that the world was flat. (laughs)
Prabhupāda: And the man was hanged who said it is round. That was their perfect knowledge. So we have to believe such perfect knowledge. When they say it has changed . . . their position. We cannot accept such knowledge. It changes every twenty-five years. (break) But we see . . . (break)
Indian Guest: . . . moon does not have its own light. It is a reflection of sunlight.
Prabhupāda: Yes, that is . . . and in the Bhagavad-gītā it states, nakṣatrāṇām ahaṁśaśī (BG 10.21).
Hanumān: Hmm, yes.
Prabhupāda: So this moon planet is one of the stars, illuminated . . . (indistinct) . . . we are getting moonlight at night, but if the earth is also reflecting like that, what is the use of moonlight?
Indian Guest: But earth is reflected on moonlight. But one of the reason is that the sky is pure dark region, but if any objects come in the sky, and if moonlight falls on that object, then you can see the object, and that is due to the reflection of light that we get from that object. You see, what happens, if moonlight does not fall on the sun, then you wouldn't be able to see the sun at all. If sunlight doesn't fall on the sun, then we would not be able to see sun at all. Similarly, if moonlight or sunlight does not fall on the earth, then they would not be able to see earth from the sun . . . earth from the moon.
