" There may be a theology without the Scriptures — a theology of nature, gathered by painful, and slow, and sometimes doubtful processes from what man sees around him in external nature and the course of history, and what he sees within him of nature and of grace. In like manner there may be and has been an astronomy of nature, gathered by man in his natural state without help from aught but his naked eyes, as he watched in the fields by night. But what is this astronomy of nature to the astronomy that has become possible through the wonderful appliances of our observatories? The Word of God is to theology as, but vastly more than, these instruments are to astronomy. It is the instrument which so far increases the possibilities of the science as to revolutionize it and to place it upon a height from which it can never more descend. What would be thought of the deluded man, who, discarding the new methods of research, should insist on acquiring all the astronomy which he would admit, from the unaided observation of his own myopic and astigmatic eyes? Much more deluded is he who, neglecting the instrument of God’s Word written, would confine his admissions of theological truth to what he could discover from the broken lights that play upon external nature, and the faint gleams of a dying or even a slowly reviving light, which arise in his own sinful soul. Ah, no! The telescope first made a real science of astronomy possible: and the Scriptures form the only sufficing source of theology. "

" Let's grant that the stars are scattered through space, hither and yon. But how hither, and how yon? To the unaided eye the brightest stars are more than a hundred times brighter than the dimmest. So the dim ones are obviously a hundred times farther away from Earth, aren't they?
Nope.
That simple argument boldly assumes that all stars are intrinsically equally luminous, automatically making the near ones brighter than the far ones. Stars, however, come in a staggering range of luminosities, spanning ten orders of magnitude ten powers of ten. So the brightest stars are not necessarily the ones closest to Earth. In fact, most of the stars you see in the night sky are of the highly luminous variety, and they lie extraordinarily far away.
If most of the stars we see are highly luminous, then surely those stars are common throughout the galaxy.
Nope again.
High-luminosity stars are the rarest. In any given volume of space, they're outnumbered by the low-luminosity stars a thousand to one. It's the prodigious energy output of high-luminosity stars that enables you to see them across such large volumes of space. "
