Material scientists want to avoid the ruling government of the Supreme Personality of Godhead, and therefore they imagine different conditions under which they suppose the planets move. The only condition, however, is the order of the Supreme Personality of Godhead.

Downfall of Gravity

Planetary orbits by order of the Supreme Lord

When bulls are yoked together and tied to a central post to thresh rice, they tread around that pivot without deviating from their proper positions – one bull being closest to the post, another in the middle, and a third on the outside. Similarly, all the planets and all the hundreds and thousands of stars revolve around the polestar, the planet of Maharaja Dhruva, in their respective orbits, some higher and some lower. Fastened by the Supreme Personality of Godhead to the machine of material nature according to the results of their fruitive acts, they are driven around the polestar by the wind and will continue to be so until the end of creation. These planets float in the air within the vast sky, just as clouds with hundreds of tons of water float in the air or as the great shyena eagles, due to the results of past activities, fly high in the sky and have no chance of falling to the ground.

PURPORT
According to the description of this verse, the hundreds and thousands of stars and the great planets such as the sun, the moon, Venus, Mercury, Mars and Jupiter are not clustered together because of the law of gravity or any similar idea of the modern scientists. These planets and stars are all servants of the Supreme Personality of Godhead, Govinda or Krishna, and according to His order they sit in their chariots and travel in their respective orbits. The orbits in which they move are compared to machines given by material nature to the operating deities of the stars and planets, who carry out the orders of the Supreme Personality of Godhead by revolving around Dhruvaloka, which is occupied by the great devotee Maharaja Dhruva. This is confirmed in the Brahma-samhita (5.52) as follows:

yac-chakshur esha savita sakala-grahanam
raja samasta-sura-murtir ashesha-tejah
yasyajïaya bhramati sambhrita-kala-chakro
govindam adi-purusham tam aham bhajami

"I worship Govinda, the primeval Lord, the Supreme Personality of Godhead, under whose control even the sun, which is considered to be the eye of the Lord, rotates within the fixed orbit of eternal time. The sun is the king of all planetary systems and has unlimited potency in heat and light." This verse from Brahma-samhita confirms that even the largest and most powerful planet, the sun, rotates within a fixed orbit, or kala-chakra, in obedience to the order of the Supreme Personality of Godhead. This has nothing to do with gravity or any other imaginary laws created by the material scientists.

Material scientists want to avoid the ruling government of the Supreme Personality of Godhead, and therefore they imagine different conditions under which they suppose the planets move. The only condition, however, is the order of the Supreme Personality of Godhead. All the various predominating deities of the planets are persons, and the Supreme Personality of Godhead is also a person. The Supreme Personality orders the subordinate persons, the demigods of various names, to carry out His supreme will. This fact is also confirmed in Bhagavad-gita (9.10), wherein Krishna says:

mayadhyakshena prakritih
suyate sa-characharam
hetunanena kaunteya
jagad viparivartate

"This material nature is working under My direction, O son of Kunti, and it is producing all moving and unmoving beings. By its rule this manifestation is created and annihilated again and again."

The orbits of the planets resemble the bodies in which all living entities are seated because they are both machines controlled by the Supreme Personality of Godhead. As Krishna says in Bhagavad-gita (18.61):

ishvarah sarva-bhutanam
hrid-deshe 'rjuna tishthati
bhramayan sarva-bhutani
yantrarudhani mayaya

"The Supreme Lord is situated in everyone's heart, O Arjuna, and is directing the wanderings of all living entities, who are seated as on a machine, made of the material energy." The machine given by material nature – whether the machine of the body or the machine of the orbit, or kala-chakra – works according to the orders given by the Supreme Personality of Godhead. The Supreme Personality of Godhead and material nature work together to maintain this great universe, and not only this universe but also the millions of other universes beyond this one.

The question of how the planets and stars are floating is also answered in this verse. It is not because of the laws of gravity. Rather, the planets and stars are enabled to float by manipulations of the air. It is due to such manipulations that big, heavy clouds float and big eagles fly in the sky. Modern airplanes like the 747 jet aircraft work in a similar way: by controlling the air, they float high in the sky, resisting the tendency to fall to earth. Such adjustments of the air are all made possible by the cooperation of the principles of purusha (male) and prakriti (female). By the cooperation of material nature, which is considered to be prakriti, and the Supreme Personality of Godhead, who is considered the purusha, all the affairs of the universe are going on nicely in their proper order.
