God is infinite, so His universe must be too. Thus is the excellence of God magnified and the greatness of His kingdom made manifest; He is glorified not in one, but in countless suns; not in a single earth, a single world, but in a thousand thousand, I say in an infinity of worlds.

Desire urges me on, while fear bridals me.

The stars in the sky are really other suns like our own, around which orbit other planets. (paraphrase)

I cleave the heavens and soar to the infinite. And while I rise from my own globe to others and penetrate ever further through the eternal field. That which others saw from afar, I leave far behind me.

I beg you, reject antiquity, tradition, faith, and authority! Let us begin anew by doubting everything we assume has been proven!

In space there are countless constellations, suns and planets; we see only the suns because they give light; the planets remain invisible, for they are small and dark. There are also numberless earths circling around their suns.

There is no absolute up or down, as Aristotle taught; no absolute position in space; but the position of a body is relative to that of other bodies. Everywhere there is incessant relative change in position throughout the universe, and the observer is always at the center of things.
