Śukadeva Gosvāmī is speaking Śrīmad-Bhāgavatam, and his disciple, Mahārāja Parīkṣit, was hearing. So at the end . . . this is the sixth chapter of . . . Sixth Canto. There are twelve Cantos of Śrīmad-Bhāgavatam, and this is Sixth Canto. So at the end of the Fifth Canto the Parīkṣit Mahārāja was informed about the hellish planets. This universe, there are different types of planets. Yasya prabhā prabhavato jagad-aṇḍa-koṭi. Yasya prabhā prabhavato jagad-aṇḍa-koṭi-koṭiṣu aśeṣa-vasudhādi vibhūti-bhinnam (Bs. 5.40). This universe is one of the universes. There are millions of universes. We do not know. We do not know even one universe. We cannot study even one universe. They are . . . they were—not are—trying to go to the moon planet, but that has become a failure. From śāstra we understand that the moon planet is situated 1,600,000 miles away from the sun, and the sun is situated in the middle of the universe. And the total diameter from one circumference to the other of the universe, it is four billions of miles. So the sun is situated at the point of two billions of miles from the circumference of the universe, and above the sun planet, 1,600,000, there is the moon. And above that there is Venus, there is Jupiter, there is Mars—all difference of 1,600,000s of miles. So it is not possible to go to the moon planet, because first of all the sun is a little . . . according to the modern scientists' calculation it is 93,000,0000. Taking it, accepted, as 93,000,000's from this earthly planet, then again add 1,600,000, that means 94,600,000 miles away from the earth there is the moon planet. It is not possible. Therefore they are now silent. They cannot go there; neither ever they went there. This is the conclusion.
So that is a controversial point, controversial, but we have to see the result. According to Vedic culture, one has to judge by the result. Not by if you simply talk nonsense, one has to accept. What is the result? Suppose if one says that "I have done very good business. I have earned so much money I have got in the bank balance . . ." You can say all these thing.
