avicyuto 'rthaḥ kavibhir nirūpito yad uttamaśloka-guṇānuvarṇanam:  "Great personalities have decided that Kṛṣṇa consciousness is the perfection of life." This kind of knowledge is required. Not that we do some research, come up with a theory, and after fifteen years say, "No, no, it is not right-it is another thing." That is not science; that is child's play.
Dr. Singh.  That is how they discover things-by research...
Śrīla Prabhupāda.  And what is the  cost  of the research? It is a scientific method for drawing money from others, that's all. In other words, it is cheating. Scientists juggle words like  plutonium ,  photons ,  hydrogen  and  oxygen , but what good will people get from this? When people hear this jugglery of words, what can they say? One scientist explains something to some extent, and then another rascal comes along and explains it again, but differently, with different words. And all the time the phenomenon has remained the same. What advancement has been made? They have simply produced volumes of books. Now there is a petrol problem. Scientists have created it. If the petrol supply dwindles away, what will these rascal scientists do? They are powerless to do anything about it.
The Billion-Dollar Dustheapp
Śrīla Prabhupāda.  Now there is a scarcity of water in India, but what are the scientists doing about it? There is more than enough water in the world, so why don't the scientists bring water where it is urgently required? They should employ irrigation immediately. But instead they are going to the moon, the dusty planet, to make it fertile. Why don't they irrigate  this  planet? There's plenty of seawater, so why don't they irrigate the Sahara or the Arabian or Rajasthani Desert? "Yes," they say, "in the future. We are trying." In their pride, they immediately say, "Yes, yes. We are trying." In  Bhagavad-gītā  it is said that when one is engaged in the business of satisfying unnecessary desires, he becomes bereft of all intelligence ( kāmais tais tair hṛta-jñānāh  [Bg. 7.20]).
This moon project is childish. Those who aspire to go to the moon are like crying children. A child cries, "Mother, give me the moon," so the mother gives the child a mirror and says, "Here is the moon, my dear son." And the child takes the mirror, sees the moon in it and says, "Oh, I have the moon." Unfortunately, this is not just a story.
Karandhara.  After spending all that money to go to the moon and bring back just a few rocks, the people on the space project decided that there was nothing more to do there.
Brahmānanda Swami.  Now they want to go to another planet, but they are short of money. Going to other planets costs millions and billions of dollars.
Śrīla Prabhupāda.  People work very hard while the rascal government takes taxes and spends money unnecessarily. There should be no sympathy when so much hard-earned money comes from the public and is spent so foolishly. Now the leaders are presenting another bluff "Don't worry, we are going to another planet. Now we shall bring  more  dust. We shall bring tons of dust. Oh, yes, now we shall have tons of dust."
Dr. Singh , They believe there may be life on Mars.
Śrīla Prabhupāda.  They may believe or not believe. What is the difference? Life exists  here , but people are fighting. So suppose there is life on Mars. There  is  life on Mars, undoubtedly. But what will we gain from this?
Dr. Singh , People are curious to know what is going on there.
