But, the question persists, why did so many creatures die in so little time after marching back and forth with the advancing or retreating ice through so many thousand years? Just recently the moon voyage has hinted at a possible clue, though it must be ventured very tentatively when man’s observational stay upon the moon has been so short.
The Apollo 11 astronauts observed and succeeded in photographing melted or glazed droplets concentrated on points and edges of moon rock. Dr. Thomas Gold, director of Cornell University’s Center for Radio Physics, has suggested that these glasslike concretions are evidence of melting, produced by a giant solar flare activated for only a few moments, but of an unexpected intensity. Giant storms are known to lick outward from the sun’s surface, but a solar disturbance of the magnitude required to account for such a melting—if it was indeed sun-produced—would have seemed from earth like the flame of a dragon’s breath. Most of the ultraviolet of the sun-storm, generated perhaps by a comet hurtling into the sun’s surface, would have been absorbed by the earth’s atmosphere. A temperature effect on earth need not have been pronounced so long as the flare was momentary. The unprotected surface of the moon, however, would have received the full impact of the dragon’s tongue.
Dr. Gold has calculated by various means that the event, if actually produced by a solar flare, lies somewhere close to thirty thousand years from us in time and is therefore unrecorded in the annals of man. But here is the curious thing. The period involved lies in the closing Ice Age, in the narrow time zone of vast extinctions in the northern hemisphere. Was the giant flare, an unheard-of phenomenon, in some way involved with the long dying of certain of the great mammals that followed? Seemingly the earth escaped visible damage because of its enveloping blanket of air. No living man knows what the flicking tongue of a dragon star might do, however, or what radiation impact or atmospheric change might have been precipitated upon earth. Some scholars are loath to accept the solar-flare version of the moon glaze because of the stupendous energy which would have to be expended, and the general known stability of the sun. But men are short-lived, and solar catastrophes like the sunward disintegration of a comet would be exceedingly rare. Until more satisfactory evidence is at hand, most scientists will probably prefer to regard the glazed rock as splashed by the heat of meteoritic impact.
Nevertheless, the turbulent outpouring of even ordinary solar flares is on so gigantic a scale as to be terrifying in a close-up view. Until there is further evidence that ours is not a sleepy dragon star, one may wonder just what happened thirty thousand years ago, and why, among so many deaths, it was man who survived. Whatever occurred, whether by ice withdrawal or the momentary penetration of the ultraviolet into our atmosphere, man’s world was changed. Perhaps there is something after all to the story of his eviction from the green Garden.
When I lie in bed now and await the hastening of Halley’s comet, I would like to dream my way back just once to that single, precise instant when the star dragon thrust out its tongue. Perhaps the story of all dragons since comes from that moment. Men have long memories when the memories are clothed in myth. But I drowse, and the train whistle mingles and howls with the heaven-sweeping light in my dream. It is 1910. I am going back once more.

The Cosmic Prison
Not till we are lost . . . do we begin to understand ourselves.
—HENRY DAVID THOREAU
“A NAME IS A PRISON, God is free,” once observed the Greek poet Nikos Kazantzakis. He meant, I think, that valuable though language is to man, it is by very necessity limiting, and creates for man an invisible prison. Language implies boundaries. A word spoken creates a dog, a rabbit, a man. It fixes their nature before our eyes; henceforth their shapes are, in a sense, our own creation. They are no longer part of the unnamed shifting architecture of the universe. They have been transfixed as if by sorcery, frozen into a concept, a word. Powerful though the spell of human language has proven itself to be, it has laid boundaries upon the cosmos.
No matter how far-ranging some of the mental probes that man has philosophically devised, by his own created nature he is forced to hold the specious and emerging present and transform it into words. The words are startling in their immediate effectiveness, but at the same time they are always finally imprisoning because man has constituted himself a prison keeper. He does so out of no conscious intention, but because for immediate purposes he has created an unnatural world of his own, which he calls the cultural world, and in which he feels at home. It defines his needs and allows him to lay a small immobilizing spell upon the nearer portions of his universe. Nevertheless, it transforms that universe into a cosmic prison house which is no sooner mapped than man feels its inadequacy and his own.
He seeks then to escape, and the theory of escape involves bodily flight. Scarcely had the first moon landing been achieved before one U.S. senator boldly announced: “We are the masters of the universe. We can go anywhere we choose.” This statement was widely and editorially acclaimed. It is a striking example of the comfort of words, also of the covert substitutions and mental projections to which they are subject. The cosmic prison is not made less so by a successful journey of some two hundred and forty thousand miles in a cramped and primitive vehicle.
To escape the cosmic prison man is poorly equipped. He has to drag portions of his environment with him, and his life span is that of a mayfly in terms of the distances he seeks to penetrate. There is no possible way to master such a universe by flight alone. Indeed such a dream is a dangerous illusion. This may seem a heretical statement, but its truth is self-evident if we try seriously to comprehend the nature of time and space that I sought to grasp when held up to view the fiery messenger that flared across the zenith in 1910. “Seventy-five years,” my father had whispered in my ear, “seventy-five years and it will be racing homeward. Perhaps you will live to see it again. Try to remember.”
And so I remembered. I had gained a faint glimpse of the size of our prison house. Somewhere out there beyond a billion miles in space, an entity known as a comet had rounded on its track in the black darkness of the void. It was surging homeward toward the sun because it was an eccentric satellite of this solar system. If I lived to see it, it would be but barely, and with the dimmed eyes of age. Yet it, too, in its long traverse, was but a flitting mayfly in terms of the universe the night sky revealed.
So relative is the cosmos we inhabit that, as we gaze upon the outer galaxies available to the reach of our telescopes, we are placed in about the position that a single white blood cell in our bodies would occupy, if it were intelligently capable of seeking to understand the nature of its own universe, the body it inhabits. The cell would encounter rivers ramifying into miles of distance seemingly leading nowhere. It would pass through gigantic structures whose meaning it could never grasp—the brain, for example. It could never know there was an outside, a vast being on a scale it could not conceive of and of which it formed an infinitesimal part. It would know only the pouring tumult of the creation it inhabited, but of the nature of that great beast, or even indeed that it was a beast, it could have no conception whatever. It might examine the liquid in which it floated and decide, as in the case of the fall of Lucretius’s atoms, that the pouring of obscure torrents had created its world.
It might discover that creatures other than itself swam in the torrent. But that its universe was alive, had been born and was destined to perish, its own ephemeral existence would never allow it to perceive. It would never know the sun; it would explore only through dim tactile sensations and react to chemical stimuli that were borne to it along the mysterious conduits of the arteries and veins. Its universe would be centered upon a great arborescent tree of spouting blood. This, at best, generations of white blood cells by enormous labor and continuity might succeed, like astronomers, in charting.
They could never, by any conceivable stretch of the imagination, be aware that their so-called universe was, in actuality, the prowling body of
a cat or the more time-enduring body of a philosopher, himself engaged upon the same quest in a more gigantic world and perhaps deceived proportionately by greater vistas. What if, for example, the far galaxies man observes make up, across void spaces of which even we are atomically composed, some kind of enormous creature or cosmic snowflake whose exterior we will never see? We will know more than the phagocyte in our bodies, but no more than that limited creature can we climb out of our universe, or successfully enhance our size or longevity sufficiently to thrust our heads through the confines of the universe that terminates our vision.
Some further “outside” will hover elusively in our thought, but upon its nature, or even its reality, we can do no more than speculate. The phagocyte might observe the salty turbulence of an eternal river system, Lucretius the fall of atoms creating momentary living shapes. We suspiciously sense, in the concept of the expanding universe derived from the primordial atom—the monobloc—some kind of oscillating universal heart. At the instant of its contraction we will vanish. It is not given us, nor can our science recapture, the state beyond the monobloc, nor whether we exist in the diastole of some inconceivable being. We know only a little more extended reality than the hypothetical creature below us. Above us may lie realms it is beyond our power to grasp.
II
This, then, is the secret nature of the universe over which the ebullient senator so recklessly proclaimed our absolute mastery. Time in that universe is in excess of ten billion years. It recedes backward into a narrowing funnel where, at some inconceivable point of concentration, the monobloc containing all the matter that composes the galaxies exploded in the one gigantic instant of creation.
Along with that explosion space itself is rushing outward. Stars and the great island galaxies in which they cluster are more numerous than the blades of grass upon a plain. To speak of man as “mastering” such a cosmos is about the equivalent of installing a grasshopper as Secretary General of the United Nations. Worse, in fact, for no matter what system of propulsion man may invent in the future, the galaxies on the outer rim of visibility are fleeing faster than he can approach them. Moreover, the light that he is receiving from them left its source in the early history of the planet earth. There is no possible way of even establishing their present existence. As the British astronomer Sir Bernard Lovell has so appropriately remarked, “At the limit of present-day observations our information is a few billion years out of date.”
Light travels at a little over one hundred and eighty-six thousand miles a second, far beyond the conceivable speed of any spaceship devised by man, yet it takes light something like one hundred thousand years just to travel across the star field of our own galaxy, the Milky Way. It has been estimated that to reach the nearest star to our own, four light-years away, would require, at the present speed of our spaceships, a time equivalent to more than the whole of written history, indeed one hundred thousand earthly years would be a closer estimate—a time as long, perhaps, as the whole existence of Homo sapiens upon earth. And the return, needless to state, would consume just as long a period.
Even if our present rocket speeds were stepped up by a factor of one hundred, human generations would pass on the voyage. An unmanned probe into the nearer galactic realms would be gone so long that its intended mission, in fact the country which sent it forth, might both have vanished into the mists of history before its messages began to be received. All this, be it noted, does not begin to involve us in those intergalactic distances across which a radio message from a cruising spaceship might take hundreds of thousands of years to be received and a wait of other hundreds of thousands before a reply would filter back.
We are, in other words, truly in the position of the blood cell exploring our body. We are limited in time, by analogy a miniature replica of the cosmos, since we too individually ascend from a primordial atom, exist, and grow in space, only to fall back in dissolution. We cannot, in terms of the time dimension as we presently know it, either travel or survive the interstellar distances.
Two years ago I chanced to wander with a group of visiting scholars into a small planetarium in a nearby city. In the dark in a remote back seat, I grew tired and fell asleep while a lecture was progressing. My eyes had closed upon a present-day starry night as represented in the northern latitudes. After what seemed in my uneasy slumber the passage of a long period of time, I started awake in the dark, my eyes fixed in amazement upon the star vault overhead. All was quiet in the neighboring high-backed seats. I could see no one. Suddenly I seemed adrift under a vast and unfamiliar sky. Constellations with which I was familiar had shifted, grown minute, or vanished. I rubbed my eyes. This was not the universe in which I had fallen asleep. It seemed more still, more remote, more enormous, and inconceivably more solitary. A queer sense of panic struck me, as though I had been transported out of time.
Only after some attempt to orient myself by a diminished pole star did the answer come to me by murmurs from without. I was not the last man on the planet, far in the dying future. My companions had arisen and left, while the lecturer had terminated his address by setting the planetarium lights forward to show the conformation of the heavens as they might exist in the remote future of the expanding universe. Distances had lengthened. All was poised, chill, and alone.
I sat for a moment experiencing the sensation all the more intensely because of the slumber which left me feeling as though ages had elapsed. The sky gave little sign of movement. It seemed drifting in a slow indeterminate swirl, as though the forces of expansion were equaled at last by some monstrous tug of gravity at the heart of things. In this remote night sky of the far future I felt myself waiting upon the inevitable, the great drama and surrender of the inward fall, the heart contraction of the cosmos.
I was still sitting when, like the slightest leaf movement on a flooding stream, I saw the first faint galaxy of a billion suns race like a silverfish across the night and vanish. It was enough: the fall was equal to the flash of creation. I had sensed it waiting there under the star vault of the planetarium. Now it was cascading like a torrent through the ages in my head. I had experienced, by chance, the farthest reach of the star prison. I had similarly lived to see the beginning descent into the maelstrom.
III
There are other confinements, however, than that imposed by the enormous distances of the cosmos. One could almost list them. There is, for example, the prison of smells. I happen to know a big black hunting poodle named Beau. Beau loves to go for walks in the woods, and at such times as I visit his owners this task of seeing Beau safely through his morning adventures is happily turned over to me.
Beau has eyes, of course, and I do not doubt that he uses them when he greets his human friends by proffering a little gift such as his food dish. After this formality, which dates to his puppyhood, is completed, Beau immediately reverts to the world of snuffles. As a long-time trusted friend, I have frequently tried to get Beau to thrust his head out of the world of smells and actually to see the universe. I have led him before the mirror in my bedroom and tried to persuade him to see himself, his own visible identity. The results, it turns out, are totally unsatisfactory if not ludicrous. Beau peers out from his black ringlets as suspiciously as an ape hiding in a bush. He drops his head immediately and pretends to examine the floor. It is evident that he detests this apparition and has no intention of being cajoled into some dangerous and undoggy wisdom by my voice.
He promptly brings his collar and makes appropriate throaty conversation. To appease his wounded feelings, I set out for a walk in the woods. It is necessary to do this with a long chain and a very tight grasp upon it. Beau is a big, powerful animal, and ringlets or no he has come from an active and carnivorous past. Once in the woods all this past suddenly emerges. One is dragged willy-nilly through leaf, thorn, and thicket on intangible trails that Beau’s swinging muzzle senses upon the wind.
His deep, wet nose has entered a world denied to me—a mad world whose contours and direction
change with every gust of air. I leap and bound with a chafed wrist through a smell universe I cannot even sense. Occasionally something squawks or bounds from under our feet and I am flung against trees or wrapped around by a flying chain.
Finally, on one memorable occasion, after a rain, Beau paused, sniffing suspiciously between two rocks on a hillside. Another rabbit? I groaned mentally, taking a tighter hold on the chain. Beau then began some careful digging, curving and patting the soil aside in a way I had never before witnessed. A small basin shaped by Beau’s forepaws presently appeared, and up from the bottom of it welled a spring-fed pool in which Beau promptly buried his snout and lapped long and lustily of water that I am sure carried the living tastes and delicate nuances disseminated from an unseen watershed.
Beau had had a proper drink of tap water before we started from home, but this drink was different. I could tell from the varied, eager, slurping sounds that emanated from Beau. He was intoxicated by living water which dim primordial memories had instructed him how to secure. I looked on, interested and sympathetic, but aware that the big black animal lived in a smell prison as I, in my way, lived in a sight prison. Our universes intersected sufficiently for us to recognize each other in a friendly fashion, but Beau would never admit the mirror image of himself into his mind, and, try as I would, the passing breeze would never inform me about the shadowy creatures that passed unglimpsed in the forest.
IV
Other prisons exist besides those dominated by the senses of smell or sight or temperature. Some involve the length of a creature’s lifetime, as in the case of five-year-old Beau, who gambols happily about his master, knowing him to be one of the everlasting immortals of his universe.
It is my belief that there has never been a culture that represented man any more than there has been a man who represented men. Our prisons, both societal and cultural, are far too complex for this. In one age religion drives the scientist-philosopher into hiding in narrow corners or castigates him as a public enemy. Such was the fate of Nicolaus Copernicus, Galileo Galilei, and others of equal importance. The pharaohs, by contrast, dreamed of traversing the sky after death in solar boats which they prepared after the fashion of Mediterranean sea craft. The Old Kingdom pharaohs, however, were entranced by a pole-star conception of their final voyage. Only later did the solar journey take precedence. I mention these cultural prisons only to indicate that man’s cosmic yearnings are very old but subjected to the vicissitudes of history.
