Prabhupāda: Then other big, big telescope, how many miles it can see?
Jayatīrtha: You can see millions of miles.
Prabhupāda: How many million? (laughter)
Jayatīrtha: You can see light years away. Many, many, many millions of miles with the big ones.
Prabhupāda: They can see four billion?
Jayatīrtha: Maybe not four billion.
Prabhupāda: Then it is imperfect. The radius, what is called, radius?
Tamāla Kṛṣṇa: Diameter?
Prabhupāda: Diameter is four billion miles, universe.
Tripurāri: One universe.
Prabhupāda: One universe. This is the smallest. Four-headed Brahma. (break) ...all universes taken together, that is one-fourth energy. And three-fourth energy is spiritual world. Ekāṁśena sthito jagat (BG 10.42), one part. (break) ...asat koṭi-yojana, one yojana equal to eight mile. And one koti means ten million. So fifty into eight, two hundred, into..., ten into ten million..., it comes. I have calculated four billion. How many millions make a billion?
Harikeśa: A thousand. (break)
Prabhupāda: Sun is situated in the middle from this circumference, two billion up and down. And the moon is situated above the sun, 1,600,000 miles. How they can go to the moon?
Devotee: They think the moon is closer than the sun.
Prabhupāda: They may think, but we are thinking in this way. Who is right?
Devotee: We are right, the Vedas.
Prabhupāda: Yes. (break) ...thinking is right because they could not go to the moon. They say they went, but actually they could not. Now they are disappointed. (break)
