Prabhupāda: Law of gravity... The big, big planets are floating in the air. Now you can explain how it is it's floating. The hint is already there in the Bhagavad-gītā, that He enters. Viṣṭabhyā idaṁ kṛtsnam ekāṁśena sthito jagat (BG 10.42), (Sanskrit) that "I enter into this universe, and by My prowess they are floating." These hints are there. Now you are a scientist; if you are actually devotee, then you try to explain from your scientific explanation that this floating is possible because God has entered within it. That is your duty. And because you're scientist, your explanation from the scientific point of view, how God has entered, how He is acting, that will be very well received by the public. So that will be great service. Actually that is the fact. It is already stated there that "I enter." We can understand. Yes, we believe. I'll explain. Just like that balloon. What is that gas? Hydrogen gas?
Martin: Helium.
Prabhupāda: Huh?
Martin: Helium gas.
Prabhupāda: Helium gas. So that helium gas has entered within the balloon and it is floating. (laughter) So if the helium gas can float, cannot God float? If helium gas has so much power, God is less than helium gas or He is more than helium gas? So what is the difficulty to understand? God says, "I enter." So similarly, the helium gas enters and it makes possible that it floats. So what is the difficulty to understand? I see in my eyes. So He can become big helium gas. Just like Kṛṣṇa says, raso 'ham apsu kaunteya: (BG 7.8) "I am the taste of the water." Water is important. We are drinking water for the taste. That taste is Kṛṣṇa. Similarly, if you explain this law of gravitation, which we have discovered, is Kṛṣṇa, prove it by your scientific knowledge, that will be your service. Actually that is a fact. That is the fact. But you have to explain, just like I have given you this example. This is scientific. As you can float a balloon by creating helium gas, so there must be some gas like that; Kṛṣṇa enters into each and every planet or universe and it floats, that's all. They, not only the planets are floating, the universes are also floating. So you accept this theory or not? If not, clearly explain.
