Searching for Heaven

“The modern scientists who are trying to travel in space are having difficulty going even to the nearest planet, the moon, to say nothing of the highest planets within the universe. There is no possibility that they can go beyond the material sky, enter the spiritual sky and see for themselves the spiritual planets, Vaikuntha. Therefore, the kingdom of God in the spiritual sky can be understood only through the authentic descriptions of the Vedas and Puranas.” (Shrila Prabhupada, Shrimad Bhagavatam, 3.15.15 Purport)
