When Politics Gives Way to Physics

People who take pride in the same object can form a knightly order but not a brotherhood of loving sons. However, as soon as pride in the exploits of the fathers is replaced by grief over their death, we will begin to perceive the Earth as a graveyard and nature as a death-bearing force. Then politics will yield to physics, which cannot be separated from astronomy. Then the Earth will be seen as a heavenly body and the stars as so many earths. The convergence of all sciences in astronomy is a...

 The Composition of Planets

As to your reasoning of the inconvenience that a centre would become further removed from another centre than from the circumference of his own globe, though centres are of the same species while the centre and circumference are of contrary nature and should therefore be furthest removed from one another, I reply as follows: Firstly, that contraries need not be at the furthest distance one from another, inasmuch as one may influence the other or may be patient of influence therefrom; as we se...

 Perceiving Infinite Suns in the Night Sky

Elpino. Why then do we not see the other bright bodies which are earths circling around the bright bodies which are suns? For beyond these we can detect no motion whatever; and why do all other mundane bodies (except those known as comets) appear always in the same order and at the same distance? Philotheo. The reason is that we discern only the largest suns, immense bodies. But we do not discern the earths because, being much smaller, they are invisible to us. Similarly it is not impossible...

 Wonder of the Natural World

Sun's nature as revealed by modern science far more wonderful: no mere angels or gold coin, but an enormous sphere into which a million Earths could be packed, in the core of which the hidden nuclei of atoms are being jammed together, hydrogen transfigured into helium, the energy latent in hydrogen for billions of years released, the Earth and other planets warmed and lit thereby, and the same process repeated four hundred billion times elsewhere in the Milky Way galaxy? The blueprints, deta...
