The earth on which we live is a spinning globe. Vast though it seems to us, it is a mere speck of matter in the greater vastness of space.
Space is, for the most part, emptiness. At great intervals there are in this emptiness flaring centres of heat and light, the fixed stars. They are all moving about in space, notwithstanding that they are called fixed stars, but for a long time men did not realize their motion. They are so vast and at such tremendous distances that their motion is not perceived. Only in the course of many thousands of years is it appreciable. These fixed stars are so far off that, for all their immensity, they seem to be, even when we look at them through the most powerful telescopes, mere points of light, brighter or less bright. A few, however, when we turn a telescope upon them, are seen to be whirls and clouds of shining vapour which we call nebulae. They are so fax off that a movement of millions of miles would be imperceptible.
