These systems are but in a later stage of development than ours; and in the course of evolution our visible universe will be changed in the same way, as I can explain. "In incalculable ages, the forward motion of the planets and their satellites will be checked by the resistance of the ether of space and the meteorites and solid matter they encounter.
Which reminds me that the Arabs say the shooting stars, meteorites, are starry stones which the angels fling at the poaching demons whom they catch sight of prowling too near the palisades of heaven. I must say I like Arab angels. My heaven would coruscate like a catherine wheel, with white-hot star-stones. Away, you dog, you prowling cur.
"That is an exceedingly significant fact," said Thorwald; "and now do you not see how strongly the meteorites confirm the story of the spectrum, and how everything tells us the universe is one in its physical structure? By these two widely different sources of information you find that beyond doubt other heavenly bodies are made of like materials with the earth.
The iron meteorites, besides metallic iron and nickel, of which they are almost entirely composed, contain hydrogen, helium, and carbonic oxide, and about the only imaginable way in which these gases could have become absorbed in the iron would be through the immersion of the latter while in a molten or vaporized state in a hot and dense atmosphere composed of them, a condition which we know to exist only in the envelopes of the sun and the stars.
The assumption that the first living organisms may have come to the earth on meteorites simply shifts the problem a step farther back, for according to all current theories of the universe, if there are in any of the heavenly bodies conditions admitting of the presence of life, these conditions have arisen from others in which life was impossible.
Some of the data collected, however, served only to perplex opinion, and even caused Chladni temporarily to renounce his. Many high authorities, headed by Laplace in 1802, declared for the lunar-volcanic origin of meteorites; but thought on the subject was turbid, and inquiry seemed only to stir up the mud of ignorance.
Certain spectroscopic coincidences, avowedly only approximate, suggesting that stars and nebulæ of every species might be formed out of variously aggregated meteorites, failed of verification by exact inquiry. And spectroscopic coincidences admit of no compromise. Those that are merely approximate are, as a rule, unmeaning.
According to Tait's sea-bird theory, the earth was at both these epochs in the plane of a sheet of meteorites forming the tail; but on each occasion the sun also was in the same plane, for the edge of the sheet of meteorites was seen to be directly in a line with the sun. The comet's head, of course, was in the same plane; but three points, not in a straight line, determine a plane.
He wondered if he should see any meteorites kindle in its path, but nothing appeared and the Ray died down, leaving everything in darkness again. Fifteen minutes passed and again the ghostly beam shot up into the night sky. Bennie looked at his watch. It was nearly half-past eight. The cold made him sleepy. He drew the blanket about him....
If we can discover whence meteorites come, and of what they are composed, I think you will agree with me that they furnish valuable testimony in our inquiry. You have no doubt had many theories as to their origin." I was just about to make answer to this implied question, when Thorwald rose and eagerly scanned the horizon.
