Brahmānanda: These particles that they have just recently found, the life-span is incredibly small, one-millionth of a trillionth of a second.
Brahmānanda: That's their life-span.
Prabhupāda: Yes. Life...
Dr. Patel: How they measured it?
Prabhupāda: Whatever they say, we have to believe. That's all. (laughter) Except Kṛṣṇa, we shall believe everything. When Kṛṣṇa says something: "No, no, these are all fictitious. There is no Kṛṣṇa, and these are all imagination." And as a rascal says, "Oh, this is scientific." This is going on. So we are not so fools that we shall believe these scientific rascals. We believe Kṛṣṇa. That's all. This is Kṛṣṇa consciousness. We are not going to believe the scientific rascals.
