We had embarked upon a sort of holiday from exploration, seeking the refreshment of disembodied flight in space. Gathering our whole company together out of all the worlds, we centered ourselves into a single mobile view-point; and then, as one being, we glided and circled among the stars and nebulae. Presently the whim took us to plunge into outer space. We hastened till the forward stars turned violet, the hinder red; till both forward and hinder vanished; till all visible features were extinguished by the wild speed of our flight. In absolute darkness we brooded on the origin and the destiny of the galaxies, and on the appalling contrast between the cosmos and our minute home-lives to which we longed to return.
Presently we came to rest. In doing so we discovered that our situation was not such as we expected. The galaxy whence we had emerged did indeed lie far behind us, no bigger than a great cloud; but it was not the featured spiral that it should have been. After some confusion of mind we realized that we were looking at the galaxy in an early stage of its existence, in fact at a time before it was really a galaxy at all. For the cloud was no cloud of stars, but a continuous mist of light. At its heart was a vague brilliance, which faded softly into the dim outer regions and merged without perceptible boundary into the black sky. Even the sky itself was quite unfamiliar. Though empty of stars, it was densely peopled with a great number of pale clouds. All seemingly were farther from us than that from which we had come, but several bulked as largely as Orion in the Earth's sky. So congested was the heaven that many of the great objects were continuous with one another in their filmy extremities, and many were separated only by mere channels of emptiness, through which loomed vistas of more remote nebulae, some of them so distant as to be mere spots of light.
It was clear that we had traveled back through time to a date when the great nebulae were still near neighbors to one another, before the explosive nature of the cosmos had done more than separate them out from the continuous and congested primal substance.
As we watched, it became obvious that events were unfolding before us with fantastic speed. Each cloud visibly shrank, withdrawing into the distance. It also changed its shape. Each vague orb flattened somewhat, and became more definite. Receding and therefore diminishing, the nebulae now appeared as lens-shaped mists, tilted at all angles. But, even as we watched, they withdrew themselves so far into the depth of space that it became difficult to observe their changes. Only our own native nebula remained beside us, a huge oval stretching across half the sky. On this we now concentrated our attention.
Differences began to appear within it, regions of brighter and of less bright mist, faint streaks and swirls, like the foam on the sea's waves. These shadowy features slowly moved, as wisps of cloud move on the hills. Presently it was clear that the internal currents of the nebula were on the whole set in a common pattern. The great world of gas was in fact slowly rotating, almost as a tornado. As it rotated it continued to flatten. It was now like some blurred image of a streaked and flattish pebble, handy for "ducks and drakes," held too near the eye to be focused. Presently we noticed, with our novel and miraculous vision, that microscopic points of intenser light were appearing here and there throughout the cloud, but mainly in its outer regions. As we watched, their number grew, and the spaces between them grew dark. Thus were the stars born.
The great cloud still span and flattened. It was soon a disc of whirling star-streams and strands of uncondensed gas, the last disintegrating tissues of the primal nebula. These continued to move within the whole by their own semi-independent activity, changing their shapes, creeping like living things, extending pseudopodia, and visibly fading as clouds fade; but giving place to new generations of stars. The heart of the nebula was now condensing into a smaller bulk, more clearly defined. It was a huge, congested globe of brilliance. Here and there throughout the disc knots and lumps of light were the embryonic star-clusters. The whole nebula was strewn with these balls of thistledown, these feathery, sparkling, fairy decorations, each one in fact pregnant with a small universe of stars.
The galaxy, for such it could now be named, continued visibly to whirl with hypnotic constancy. Its tangled tresses of star-streams were spread abroad on the darkness. Now it was like a huge broad-brimmed white sombrero, the crown a glowing mass, the brim a filmy expanse of stars. It was a cardinal's hat, spinning. The two long whirling tassels on the brim were two long spiraling star-streams. Their frayed ex tremities had broken away and become sub-galaxies, revolving about the main galactic system. The whole, like a spinning top, swayed; and, as it tilted before us, the brim appeared as an ever narrower ellipse, till presently it was edge-on, and the outermost fringe of it, composed of non-luminous matter, formed a thin, dark, knotted line across the glowing inner substance of nebula and stars-Peering, straining to see more precisely the texture of this shimmering and nacrous wonder, this largest of all the kinds of objects in the cosmos, we found that our new vision, even while embracing the whole galaxy and the distant galaxies, apprehended each single star as a tiny disc separated from its nearest neighbors much as a cork on the Arctic Ocean would be separated from another cork on the Antarctic. Thus, in spite of the nebulous and opalescent beauty of its general form, the galaxy also appeared to us as a void sprinkled with very sparse scintillations.
Observing the stars more closely, we saw that while they streamed along in companies like shoals of fishes, their currents sometimes interpenetrated. Then seemingly the stars of the different streams, crossing one another's paths, pulled at one another, moving in great sweeping curves as they passed from one neighbor's influence to another. Thus, in spite of their remoteness each from each, the stars often looked curiously like minute living creatures taking cognizance of one another from afar. Sometimes they swung hyperbolically round one another and away, or, more rarely, united to form binaries.
So rapidly did time pass before us that aeons were packed into moments. We had seen the first stars condense from the nebular tissue as ruddy giants, though in the remote view inconceivably minute. A surprising number of these, perhaps through the centrifugal force of their rotation, were burst asunder to form binaries, so that, increasingly, the heaven was peopled by these waltzing pairs. Meanwhile, the giant stars slowly shrank and gathered brightness. They passed from red to yellow, and on to dazzling white and blue. While other young giants condensed around them, they shrank still further, and their color changed once more to yellow and to smoldering red. Presently we saw the eldest of the stars one by one extinguished like sparks from a fire. The incidence of this mortality increased, slowly but steadily. Sometimes a "nova" flashed out and faded, outshining for a moment all its myriad neighbors. Here and there a "variable" pulsated with inconceivable rapidity. Now and again we saw a binary and a third star approach one another so closely that one or other of the group reached out a filament of its substance toward its partner. Straining our supernatural vision, we saw these filaments break and condense into planets. And we were awed by the infinitesimal size and the rarity of these seeds of life among the lifeless host of the stars.
