In the Bhagavad-gītā you'll find that if you want to go to the higher planets, there is ways and means. So we have discussed this point in our small book Easy Journey to Other Planets
So there is life in other planet, there is standard of living. Now, in the moon planet we understand the duration of life is ten thousands of years according to our calculation. Scientifically, everything is relative. Just like nowadays, formerly, to come to your country it would take two months from India on the surface. And now the aeroplane is there, we come within one day, within fifteen hours or twenty hours.
So everything is relative. Just like the sputnik. The sputnik surrounded, circumambulated the earth, in one hour, twenty-five minutes, three times. That means by the sputnik speed, the three days . . . to circumambulate the earth three times means three day and night. That means according to our calculation, seventy-two hours. That seventy-two hours was finished in one hour and twenty-five. How? Because the thing is relative. If you accelerate your speed, the whole thing becomes relative.
