How Is It Floating

“We often wonder how these big planets are floating in the air. It is stated here that the Supreme Lord, by His inconceivable energy, is sustaining all these big planets and systems of galaxies. The word achintya (inconceivable) is very significant in this connection. God's energy is beyond our conception, beyond our thinking jurisdiction, and is therefore called inconceivable (achintya). Who can argue this point? He pervades this material world and yet is beyond it. We cannot even comprehend this material world, which is insignificant compared to the spiritual world-so how can we comprehend what is beyond? Achintya means that which is beyond this material world, that which our argument, logic and philosophical speculation cannot touch, that which is inconceivable. Therefore intelligent persons, avoiding useless argument and speculation, should accept what is stated in scriptures like the Vedas, Gita, and Shrimad-Bhagavatam and follow the principles they set down. This will lead one to understanding.” (Shrila Prabhupada, Bhagavad-gita, 8.9 Purport)
