Tey nodded in agreement.
One of the strangers stepped forward and gestured with his hand. The light to which the Earthmen were accustomed went out on the other side of the partition.
“I should have thought of the lights!” Moot Ang groaned.
“I did,” Kari said, switching off the normal lighting and turning on two powerful lamps fitted with “430” filters.
“But it’ll make us look like corpses,” said Taina. “Humanity doesn’t look its best in this light.”
“You have no cause for worry,” Moot Ang said. “Their range of perfect vision extends far into the violet region, and perhaps even into the ultraviolet. That suggests that they are sensitive to a great many more shades and obtain a softer visual picture than we.”
“We probably look yellower to them than we really are,” Tey said after a moment’s thought.
“That’s better than the bluish colour of a corpse,” Taina said. “Just look around!”
The Earthmen took several photographs and then passed an osmin-crystal overtone speaker through a small airlock in the screen. The strangers took it and put it on a tripod. Kari directed a narrow beam of radio waves at the disc antenna and the speech and music of Earth could be heard in the fluorine planet’s space ship. A device for analysing the air and measuring the temperature and atmospheric pressure was passed through in the same way. As could have been expected, the temperature inside the white space ship turned out to be much lower — no more than seven degrees. The atmospheric pressure was higher than on Earth, and the force of gravity, almost the same.
“Their body temperature is probably higher,” Afra said. “Ours too is more than the Earth’s normal average of twenty degrees. I would say their body temperature is about fourteen of our degrees.”
The others also passed through some devices enclosed in two mesh containers which made it impossible to judge of their designation.
One of the containers emitted high-pitched intermittent sounds that seemed to vanish into the distance. From this the Earthmen gathered that the others could hear higher notes than they. If the range of their hearing was about the same, they probably could not hear the lower notes in our speech and music.
The strangers switched on terrestrial lighting again and the Earthmen turned off the blue light. Two of the strangers, a man and a woman, approached the transparent wall. They threw off their dark-red clothing and stood naked, hand in hand, before the Earthmen. The bodies of the strangers were even more similar to those of the people of Earth than their faces. The harmonious proportions fully accorded with the earthly concept of beauty. True, the lines were more sharply defined, more angular, producing a sculptured effect that was enhanced by the play of light and shadow on their grey skin.
Their heads sat proudly on their long necks. The man had the broad shoulders and general physique of a worker and fighter, while the wide hips of the woman in no way jarred with intellectual power that emanated from these inhabitants of an unknown planet.
When the strangers stepped back with the now familiar gesture of invitation and the yellow terrestrial lights went out, the Earthmen no longer hesitated.
At the commander’s request, Tey Eron and Afra Devi stepped up hand in hand before the transparent partition. In spite of the unearthly lighting which lent their bodies the cold blue tint of marble, their superb beauty caused a gasp of admiration to escape their comrades. The strangers too, dimly visible in the unlighted gallery, seemed similarly affected; they looked at one another in wonder and exchanged brief gestures.
At last the strangers finished photographing and turned on their own light.
“Now I have no doubt that they know what love is,” said Taina, “true, beautiful human love …since their men and women are so beautiful and so clever.”
“You are quite right, Taina, and that is all the more heartening since it means they will understand us in everything,” Moot Ang replied. “Look at Kari! See you don’t fall in love with that girl from the fluorine planet, Kari. That would be a real tragedy for you.”
The navigator started, and tore his eyes with difficulty away from the inhabitants of the white space ship.
“I could,” he confessed sadly. “I really could in spite of all the differences between us, in spite of the vast distances between our planets.” The young man turned back with a sigh to contemplate the smiling face of the woman from the other planet.
The strangers now moved a green screen up to the par-tion. On it tiny figures mounted a steep incline in a procession, carrying heavy loads. On reaching the flat top each dropped the load and threw himself down flat. Similar to animated cartoons as they were known on Earth, the picture clearly conveyed the idea of fatigue. The strangers were suggesting a break for rest. The Earthmen too were tired, for the many hours of tense anticipation of the encounter in space and the first impressions of the meeting had been exhausting indeed.
The inhabitants of the fluorine planet had obviously expected to meet men from other planets on their travels, and had prepared for such encounters by making pantomime films as a substitute for language. The Tellur had made no such preparations, but a way out was found nevertheless. Yas Tin, the ship’s artist, dashed off a series of sketches on a drawing screen that was moved up. First he drew figures expressive of exhaustion, and then a face with such an obviously questioning expression that there was a stir of animation among the people on the other side of the partition just as there had been when Tey and Afra appeared before them. Finally Yas drew a sketch of the Earth revolving around its axis as it coursed on its orbit around the Sun, divided the complete revolution into twenty-four equal parts and shaded half of the diagram. The others produced a similar diagram. Both sides set metronomes in motion which helped to establish the duration of the units of time. The Earthmen learned that the fluorine planet made one complete revolution around its axis in roughly fourteen terrestrial hours and circled its blue sun every nine hundred days. The break for rest which the strangers suggested was the equivalent of five terrestrial hours.
Still dazed by their experience, the Earthmen left the communication gallery. The lights went out in the gallery and the outside illumination of the ships was extinguished. The two space ships now hung dark and lifeless side by side in the frigid blackness of space.
Inside, however, work went on at full speed. Here the human brain drew on its inexhaustible reserves of ingenuity to devise new means for conveying to other human beings from a distant planet the knowledge accumulated in the course of thousands of years of labour, perils and suffering — knowledge which had freed man first from the power of primordial nature, then from the shackles of savage social orders, disease and premature old age, and finally opened the way to the boundless expanses of the Universe.
The second meeting in the gallery began with a demonstration of stellar maps. Neither the Earthmen nor the inhabitants of the fluorine planet had ever seen the constellations they had passed on respective courses. (Only later, on Earth, was it established that the fluorine planet’s blue sun was located in a minor stellar cluster in the Milky Way not far from Tau Ophiuchi.) The strangers had been heading for a star cluster on the northern edge of Ophiuchus when they came upon the Tellur at the southern bounds of Hercules.
At the strangers’ end of the gallery a screen made of red metal slats about the height of man was set up. Through the chinks between the slats the Earthmen thought they saw something whirling. Then suddenly the slats turned sideways, disappearing from sight, and before the Earthmen’s gaze there now appeared a vast expanse of space with bright blue spheres spinning in the depths. These were the fluorine planet’s satellites. Gradually the planet itself approached. A wide blue belt of solid cloud circled it at the equator. In the polar and subpolar zones there were glimmers of grey and red, and between these and the equatorial belt there were strips of the purest white like the surface of the strangers’ space ship. Here there was less vapour in the atmosphere and one could faintly make out the contours of seas, continents, and mountain ranges. The planet was bigger than Earth. Its fast rotation created a powerful magnetic field around it. A violet glow extended in long tongues from the equator into the blackness of outer space.
Hour after hour the Earthmen sat in breathless silence before the partition watching the startlingly realistic views of the fluorine planet which the mysterious device brought to them. They saw the violet waves of oceans of hydrofluoric acid washing beaches of black sand, red crags, and the slopes of jagged mountains radiating a cold pale-blue glow.
Toward the poles the blue of the atmosphere grew deeper and the blue light of the violet star around which the planet revolved seemed purer. The mountains here were rounded cupolas, smooth ridges or flat-topped bulges with a bright opalescent glow. A dark-blue twilight had settled in the deep valleys extending from the polar mountains to the scalloped belt of equatorial seas. An opalescent pall of blue clouds hovered over the great gulfs. The shores of the seas were fringed with gigantic structures of red metal and what looked like grass-green stone. Similar structures crept up the longitudinal valleys toward the poles. They must have covered great areas to be visible from such a height. Between the built-up areas there were wide tracts of dense bluish-green vegetation or the rounded cupolas of mountains that had an inner glow like opal or moonstone on Earth. The round ice caps of frigid hydrogen fluoride on the poles gleamed like sapphires.
Blue and violet of all shades were the predominant colours. The very air seemed to be shot through with a bluish radiance. This was a cold, impassive world, as pure, distant and illusory as if reflected in a crystal. A world devoid of the caressing warmth of the multitude of red, orange and yellow colours of Earth.
There were chains of cities in both hemispheres in the areas corresponding to the polar and temperate zones of Earth. The mountains grew more and more jagged and sombre toward the equator. Here sharp peaks jutted up from the seas enveloped in clouds of vapour, and the ranges ran latitudinally, along the fringes of the tropical regions.
Dense masses of blue vapour curled over the tropical zone. Under the heat of the blue star the highly volatile hydrofluoric acid saturated the atmosphere with its vapours, which rolled in vast walls of cloud toward the temperate zones to condense there and pour back into the equatorial belt. Giant dams checked the flow of these mighty streams which were enclosed in aqueducts and tunnels and used to run the planet’s power stations.
Fields of huge crystals of quartz dazzled the eye — evidently silicon took the place of our salt in the hydrofluoric seas.
The screen carried the viewers to the fluorine planet’s cities, sharply outlined in the cold blue light. All of the planet with the exception of the mysterious equatorial zone under its blue shroud of vapour, seemed to be inhabited and bore the imprint of man’s labour and intelligence. Indeed, much more so than Earth, where great untouched tracts under natural preserves, ancient ruins and abandoned workings still remained.
The labour of countless generations and thousands of millions of people reigned supreme over the entire planet, triumphing over the elemental forces of Nature — the turbulent floods and the dense atmosphere shot through with the fierce radiation of the blue star and laden with electrical charges of fantastic power.
The Earthmen could not tear their eyes away from the screen, but as they looked, their imagination conjured up visions of their own planet. But theirs was not the limited vision their forebears in ancient times had had of some particular expanse of field or forest, some rocky, melancholy mountains, or the shores of gleaming seas basking in the warmth of the sun, depending on where they were born or brought up. For the astronauts of the Tellur the world was an entity of frigid, temperate and torrid zones, and their mind’s eye ranged over the splendid panorama of silvery steppes where the wind roamed freely, and the mighty forests of firs and cedars and birches and palms and giant eucalyptuses; the mist-wrapped shores of the northern seas with their moss-covered crags and the white coral reefs nestling in the blue radiance of tropical seas; the cold, dazzling brilliance of snow-capped mountain ranges and the desert aquiver with heat under the blazing sun; the great rivers majectically flowing on to the sea and mountain torrents whipping themselves into foam against their rocky beds; the wealth of colour, the multitude of flowers, the blue sky with its flocks of white clouds, the warmth of sunshine and the chill of a rainy day, the endless kaleidoscope of the seasons. And with all this great richness of nature a still greater diversity of people in all their beauty, with their aspirations, exploits, dreams, sorrows and joys, songs and dances, tears and longings…
The same power of intelligent labour with its ingenuity, skill, imagination and artistry was evident in everything — in dwellings, factories, machines and ships alike.
Perhaps the inhabitants of the fluorine planet in their turn saw with their enormous eyes more than the Earth-men did in the cold blue tones of their planet aivd had progressed farther in remaking their more monotonous nature?
We who were the product of an oxygen atmosphere which is hundreds of thousands of times more common in the Universe had found and would still find an enormous number of planets offering conditions favourable to life as we knew it, and would no doubt also find other living beings like us on other heavenly bodies. But would they be able to do likewise — they who were the product of rare fluorine, with their fluoric proteins and bones, their blood with the blue corpuscles that assimilated fluorine as our red corpuscles assimilated oxygen?
These people were confined within the limited space of their planet, and there was little doubt that they had long searched for other human beings like themselves, or at least for planets with a fluorine atmosphere suitable for them. But theirs was a formidable problem: to find such rare planets in the vast expanses of space, to reach them through distances of thousands of light years. One could easily understand their disappointment on meeting, and probably not for the first time, with oxygen-breathing humans.
In the strangers’ end of the gallery the views of the landscape of the fluorine planet were followed by enormous structures. The walls, which leaned inward, reminded one of Tibetan architecture. There were no angles, no horizontal lines. Transitions from the vertical to the horizontal followed helical lines. A dark opening, a twisted oval in shape, appeared in a wall in the distance. As it came closer the lower part of the spiral turned out to be a broad-winding road rising to a huge entrance that led into a building as big as a good-sized town. Over the entrance were series of red-bordered blue signs that had looked like ripples on water from the distance. The entrance came nearer still and the Earthlings gazing at it spellbound caught a glimpse of a great dimly-lit hall inside with walls that glowed like fluorescent fluorite.
Suddenly the picture vanished. The astronauts of the Tellur, who had felt themselves on the threshold of some tremendous revelation, stood stunned with disappointment. The gallery on the other side of the partition was now lit with the ordinary blue light. Some of the strangers appeared, but this time their movements were jerky and hurried.
A series of figures appeared on the screen in such rapid succession that the Earthlings could hardly follow them. At first a white space ship like the one lying alongside the Tellur was moving through the darkness of space; one clearly saw the whirling central ring casting gleaming rays in all directions. Suddenly the ring stopped and the ship hung motionless not far from a blue dwarf star. Thin pencil-lines of rays shot out from the ship and reached another one like it that appeared in the left corner of the screen suspended in space alongside a space ship which the Earthlings recognized as the Tellur. As soon as the white space ship received the message, it cast loose from the Tellur and disappeared into the black void of space.
Moot Ang sighed so loudly that his colleagues turned round to look at him.
“I’m afraid they’re going soon,” he said. “They are in contact with another of their ships somewhere very far away, although how they communicate over such vast distances is more than I can understand. Now something’s happened to the second ship and it has sent a call for help to our friends here.”
“Perhaps it hasn’t been damaged. Perhaps it’s found something very important,” Taina hardly breathed the words.
“Perhaps. Whatever the reason, they’re leaving. We must hurry up and photograph and record as much as possible before they go. Most important, of course, are the charts, their course and what they have encountered on their voyage. I have no doubt they have run across people who breathe oxygen like us.”
Further exchanges revealed that the strangers could still stay the equivalent of one terrestrial day. The crew of the Tellur, stimulated by special drugs, set to work with frenzied vigour no less than that of the strangers.
Textbooks with illustrations were photographed and recordings were made of each other’s language. Collections of minerals, fluids and gases packed in transparent containers were exchanged. The chemists of both planets pored over the meaning of symbols representing the composition of organic and inorganic substances. Afra, pale with fatigue, stood before diagrams of physiological processes, genetic charts and formulas, and a chart showing the embryonic development of the human organism on the fluorine planet. The endless chains of molecules of fluorine-resistant proteins were astoundingly similar to our protein molecules: there were the same energy filters, the same barriers arising from the battle of living matter with entropy.
