Not illustrated. 1922 Excerpt: ...93,000,000 x 2 = 186,000,000 miles diameter of earth's orbit, the distance to the stars must be billions of miles or even more, they must be a terrific size, and the earth is only like a speck of dust in the Brobdinagian Universe, &c, &c, &c. But we have not yet done with that angle. Regarded as an angle of parallax, and considered to be equivalent to just such an angle as a surveyor would use in measuring a plot of land, it was of course presumed that the two lines of sight converged so as to meet at a point thirty-five million miles away. (See diagram 18.) This, however, is a mistake, for the two lines of observation, when placed in their proper relations to each other, and in the order as taken, should be as in diagram 19, which shows that they diverge. We will prove this in diagram 20. A study of our earlier diagram 6--which gives a suggestion of a small section mapped out with dotted lines to indicate latitude and longitude in universal space--reveals the fact that twelve hours' rotation of the earth does not transfer the observer from A to the point B in space, because--according to Copernican astronomy--the earth is not only rotating on its axis during those twelve hours, but also rushing through space in a gigantic orbit round the sun at the rate of sixty-six thousand miles an hour, or thereabouts, and so when the observer takes his second observation he is something like three-quarters of a million miles away from where he started. He is at latitude G in diagram 6. Now let us study diagram 20, which has been made as simple as possible in order to illustrate the principles involved the more clearly. The letter C is used in this diagram to take the place of G in the earlier diagram 6, because it is simpler to describe the movements of the...
