If... the motion of the earth were circular, it would be violent and contrary to nature, and could not be eternal, since ... nothing violent is eternal .... It follows, therefore, that the earth is not moved with a circular motion.

I tell you that if natural bodies have it from Nature to be moved by any movement, this can only be circular motion, nor is it possible that Nature has given to any of its integral bodies a propensity to be moved by straight motion. I have many confirmations of this proposition, but for the present one alone suffices, which is this. I suppose the parts of the universe to be in the best arrangement, so that none is out of its place, which is to say that Nature and God have perfectly arranged their structure. This being so, it is impossible for those parts to have it from Nature to be moved in straight, or in other than circular motion, because what moves straight changes place, and if it changes place naturally, then it was at first in a place preternatural to it, which goes against the supposition. Therefore, if the parts of the world are well ordered, straight motion is superfluous and not natural, and they can only have it when some body is forcibly removed from its natural place, to which it would then return by a straight line, for thus it appears that a part of the earth does [move] when separated from its whole. I said "it appears to us," because I am not against thinking that not even for such an effect does Nature make use of straight line motion.

 
Galileo Galilei
 

The harmony of music exists equally with the harmony of movement in nature.
Man has not invented the harmony of music. It is one of the underlying principles of life. Neither could the harmony of movement be invented: it is essential to draw one’s conception of it from Nature herself, and to see the rhythm of human movement from the rhythm of water in motion, from the blowing of the winds on the world, in all the earth’s movements, in the motions of animals, fish, birds, reptiles, and even in primitive man, whose body still moved in harmony with nature…..All the movements of the earth follow the lines of wave motion. Both sound and light travel in waves. The motion of water, winds, trees and plants progresses in waves. The flight of a bird and the movements of all animals follow lines like undulating waves. If then one seeks a point of physical beginning for the movement of the human body, there is a clue in the undulating motion of the wave.

On this new earth, cleansed and renovated—this eternal new earth—we will fulfill our eternal purpose for God. It is heaven on earth—always better.

 
Paul Enns
 

Hence I feel no shame in asserting that this whole region engirdled by the moon, and the center of the earth, traverse this grand circle amid the rest of the planets in an annual revolution around the sun. Near the sun is the center of the universe. Moreover, since the sun remains stationary, whatever appears as a motion of the sun is really due rather to the motion of the earth.
