Sinopsis
This historic book may have numerous typos, missing text or index. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. 1892. Not illustrated. Excerpt: ... REVOLUTION OF THE UNIVERSE. 1. It was long known as one of the most elementary truths of astronomy, that the earth and the planets revolve around the sun; but the question recently began to be raised among astronomers, " Does the sun stand still, or does it move around some other object in space, carrying its train of planets and their satellites along with it in its orbit?" 2. Attention being thus specially directed to this subject, it was soon found that the sun had an appreciable motion, which tended in the direction of a lily-shaped group of small stars, called the constellation of Hercules. Toward this constellation the stars seem to be opening out; while at the opposite point of the sky their mutual distances are apparently diminishing, as if they were drifting away, like the foaming wake of a ship, from the sun's course. 3. When this great physical truth was established beyond the possibility of doubt, the next subject of investigation was the point or center around which the sun performed this marvelous revolution; and, after a series of elaborate observations and most ingenious calculations, this intricate problem was also satisfactorily solved--one of the greatest triumphs of human genius. 4. Madler, of Dorpat, found that Alcyone, the brightest star of the Pleiades, is the center of gravity of our vast solar system--the luminous hinge in the heavens around which our sun and his attendant planets are moving through space. 5. Vast as is the distance which separates our sun from this central group--a distance thirty-four millions of times greater than the distance between the sun and our earth--yet so tremendous is the force exerted by Alcyone, that it draws our system irresistibly around it at the rate of four hundred and twenty-two thousand miles a day,...
