The Songs of Distant Earth (2 page)

This phantom was given the nickname “neutrino” – neutron plus bambino. There seemed no hope of ever detecting so elusive an entity; but in 1956, by heroic feats of instrumentation, the physicists had caught the first few specimens. It was also a triumph for the theoreticians, who now found their unlikely equations verified.

The world as a whole neither knew nor cared; but the countdown to doomsday had begun.

3. Village Council

T
arna’s local network was never more than ninety-five per cent operational – but on the other hand never
less
than eighty-five per cent of it was working at any one time. Like most of the equipment on Thalassa, it had been designed by long-dead geniuses so that catastrophic breakdowns were virtually impossible. Even if many components failed, the system would still continue to function reasonably well until someone was sufficiently exasperated to make repairs.

The engineers called this “graceful degradation” – a phrase that, some cynics had declared, rather accurately described the Lassan way of life.

According to the central computer, the network was now hovering around its normal ninety-five per cent serviceability, and Mayor Waldron would gladly have settled for less. Most of the village had called her during the past half-hour, and at least fifty adults and children were milling round in the council chamber – which was more than it could comfortably hold, let alone seat. The quorum for an ordinary meeting was twelve, and it sometimes took draconian measures to collect even that number of warm bodies in one place. The rest of Tarna’s five hundred and sixty inhabitants preferred to watch – and vote, if they felt sufficiently interested – in the comfort of their own homes.

There had also been two calls from the provincial governor, one from the president’s office, and one from one North Island news service, all making the same completely unnecessary request. Each had received the same short answer: Of course we’ll tell you if anything happens … and thanks for your interest.

Mayor Waldron did not like excitement, and her moderately successful career as a local administrator had been based on avoiding it. Sometimes, of course, that was impossible; her veto would hardly have deflected the hurricane of ‘09, which – until today – had been the century’s most notable event.

“Quiet, everybody!” she cried. “Reena – leave those shells alone – someone went to a lot of trouble arranging them! Time you were in bed, anyway! Billy – off the table!
Now!”

The surprising speed with which order was restored showed that, for once, the villagers were anxious to hear what their mayor had to say. She switched off the insistent beeping of her wrist-phone and routed the call to the message centre.

“Frankly, I don’t know much more than you do – and it’s not likely we’ll get any more information for several hours. But it certainly
was
some kind of spacecraft, and it had already reentered – I suppose I should say entered – when it passed over us. Since there’s nowhere else for it to go on Thalassa, presumably it will come back to the Three Islands sooner or later. That might take hours if it’s going right round the planet.”

“Any attempt at radio contact?” somebody asked.

“Yes, but no luck so far.”

“Should we even try?” an anxious voice said.

A brief hush fell upon the whole assembly; then Councillor Simmons, Mayor Waldron’s chief gadfly, gave a snort of disgust.

“That’s ridiculous. Whatever we do, they can find us in about ten minutes. Anyway, they probably know exactly where we are.”

“I agree completely with the councillor,” Mayor Waldron said, relishing this unusual opportunity. “Any colony ship will certainly have maps of Thalassa. They may be a thousand years old – but they’ll show First Landing.”

“But suppose
–
just suppose – that they
are
aliens?”

The mayor sighed; she thought that thesis had died through sheer exhaustion, centuries ago.

“There are no aliens,” she said firmly. “At least, none intelligent enough to go starfaring. Of course, we can never be one hundred per cent certain – but Earth searched for a thousand years with every conceivable instrument.”

“There’s another possibility,” said Mirissa, who was standing with Brant and Kumar near the back of the chamber. Every head turned towards her, but Brant looked slightly annoyed. Despite his love for Mirissa, there were times when he wished that she was not quite so well-informed, and that her family had not been in charge of the Archives for the last five generations.

“What’s that, my dear?”

Now it was Mirissa’s turn to be annoyed, though she concealed her irritation. She did not enjoy being condescended to by someone who was not really very intelligent, though undoubtedly shrewd – or perhaps cunning was the better word. The fact that Mayor Waldron was always making eyes at Brant did not bother Mirissa in the least; it merely amused her, and she could even feel a certain sympathy for the older woman.

“It could be another robot seedship, like the one that brought our ancestor’s gene patterns to Thalassa.”

“But
now –
so late?”

“Why not? The first seeders could only reach a few percent of light velocity. Earth kept improving them – right up to the time it was destroyed. As the later models were almost ten times faster, the earlier ones were overtaken in a century or so; many of them must still be on the way. Don’t you agree, Brant?”

Mirissa was always careful to bring him into any discussion and, if possible, to make him think he had originated it. She was well aware of his feelings of inferiority and did not wish to add to them.

Sometimes it was rather lonely being the brightest person in Tarna; although she networked with half a dozen of her mental peers on the Three Islands, she seldom met them in the face-to-face encounters that, even after all these millennia, no communications technology could really match.

“It’s an interesting idea,” Brant said. “You could be right.”

Although history was not his strong point, Brant Falconer had a technician’s knowledge of the complex series of events that had led to the colonization of Thalassa. “And what shall we do,” he asked, “if it’s another seedship, and tries to colonize us all over again? Say ‘Thanks very much, but not today’?”

There were a few nervous little laughs; then Councillor Simmons remarked thoughtfully, “I’m sure we could handle a seedship if we had to. And wouldn’t its robots be intelligent enough to cancel their program when they saw that the job had already been done?”

“Perhaps. But they might think they could do a better one. Anyway, whether it’s a relic from Earth or a later model from one of the colonies, it’s bound to be a robot of some kind.”

There was no need to elaborate; everyone knew the fantastic difficulty and expense of
manned
interstellar flight. Even though technically possible, it was completely pointless. Robots could do the job a thousand times more cheaply.

“Robot or relic – what are we going to do about it?” one of the villagers demanded.

“It may not be our problem,” the mayor said. “Everyone seems to have assumed that it will head for First Landing, but why should it? After all, North Island is much more likely
–
”

The mayor had often been proved wrong, but never so swiftly. This time the sound that grew in the sky above Tarna was no distant thunder from the ionosphere but the piercing whistle of a low, fast-flying jet. Everyone rushed out of the council chamber in unseemly haste; only the first few were in time to see the blunt-nosed delta-wing eclipsing the stars as it headed purposefully towards the spot still sacred as the last link with Earth.

Mayor Waldron paused briefly to report to central, then joined the others milling around outside.

“Brant – you can get there first. Take the kite.”

Tarna’s chief mechanical engineer blinked; it was the first time he had ever received so direct an order from the mayor. Then he looked a little abashed.

“A coconut went through the wing a couple of days ago. I’ve not had time to repair it because of that problem with the fishtraps. Anyway, it’s not equipped for night flying.”

The mayor gave him a long, hard look.

“I hope my car’s working,” she said sarcastically.

“Of course,” Brant answered, in a hurt voice. “All fuelled up, and ready to go.”

It was quite unusual for the mayor’s car to go anywhere; one could walk the length of Tarna in twenty minutes, and all local transport of food and equipment was handled by small sandrollers. In seventy years of official service the car had clocked up less than a hundred thousand kilometres, and, barring accidents, should still be going strong for at least a century to come.

The Lassans had experimented cheerfully with most vices; but planned obsolescence and conspicuous consumption were not among them. No one could have guessed that the vehicle was older than any of its passengers as it started on the most historic journey it would ever make.

4. Tocsin

N
o one heard the first tolling of Earth’s funeral bell – not even the scientists who made the fatal discovery, far underground, in an abandoned Colorado gold mine.

It was a daring experiment, quite inconceivable before the mid-twentieth century. Once the neutrino had been detected, it was quickly realized that mankind had a new window on the universe. Something so penetrating that it passed through a planet as easily as light through a sheet of glass could be used to look into the hearts of suns.

Especially
the
Sun. Astronomers were confident that they understood the reactions powering the solar furnace, upon which all life on Earth ultimately depended. At the enormous pressures and temperatures at the Sun’s core, hydrogen was fused to helium, in a series of reactions that liberated vast amounts of energy. And, as an incidental by-product, neutrinos.

Finding the trillions of tons of matter in their way no more obstacle than a wisp of smoke, those solar neutrinos raced up from their birthplace at the velocity of light. Just two seconds later they emerged into space, and spread outward across the universe. However many stars and planets they encountered, most of them would still have evaded capture by the insubstantial ghost of “solid” matter when Time itself came to an end.

Eight minutes after they had left the Sun, a tiny fraction of the solar torrent swept through the Earth – and an even smaller fraction was intercepted by the scientists in Colorado. They had buried their equipment more than a kilometre underground so that all the less penetrating radiations would be filtered out and they could trap the rare, genuine messengers from the heart of the Sun. By counting the captured neutrinos, they hoped to study in detail conditions at a spot that, as any philosopher could easily prove, was forever barred from human knowledge or observation.

The experiment worked; solar neutrinos were detected. But –
there were far too few of them.
There should have been three or four times as many as the massive instrumentation had succeeded in capturing.

Clearly, something was wrong, and during the 1970s the Case of the Missing Neutrinos escalated to a major scientific scandal. Equipment was checked and rechecked, theories were overhauled, and the experiment rerun scores of times – always with the same baffling result.

By the end of the twentieth century, the astrophysicists had been forced to accept a disturbing conclusion – though as yet, no one realized its full implications.

There was nothing wrong with the theory, or with the equipment. The trouble lay inside the Sun.

The first secret meeting in the history of the International Astronomical Union took place in 2008 at Aspen, Colorado – not far from the scene of the original experiment, which had now been repeated in a dozen countries. A week later IAU Special Bulletin No. 55/08, bearing the deliberately low-key title “Some Notes on Solar Reactions”, was in the hands of every government on Earth.

One might have thought that as the news slowly leaked out, the announcement of the End of the World would have produced a certain amount of panic. In fact, the general reaction was a stunned silence – then a shrug of the shoulders and the resumption of normal, everyday business.

Few governments had ever looked more than an election ahead, few individuals beyond the lifetimes of their grandchildren. And anyway, the astronomers might be wrong. Even if humanity was under sentence of death, the date of execution was still indefinite. The Sun would not blow up for at least a thousand years, and who could weep for the fortieth generation?

5. Night Ride

N
either of the two moons had risen when the car set off along Tarna’s most famous road, carrying Brant, Mayor Waldron, Councillor Simmons, and two senior villagers. Though he was driving with his usual effortless skill, Brant was still smouldering slightly from the mayor’s reprimand. The fact that her plump arm was accidentally draped over his bare shoulders did little to improve matters.

But the peaceful beauty of the night and the hypnotic rhythm of the palm trees as they swept steadily through the car’s moving fan of light quickly restored his normal good humour. And how could such petty personal feelings be allowed to intrude, at such an historic moment as this?

In ten minutes, they would be at First Landing and the beginning of their history. What was waiting for them there? Only one thing was certain; the visitor had homed on the still-operating beacon of the ancient seedship. It knew where to look, so it must be from some other human colony in this sector of space.

On the other hand – Brant was suddenly struck by a disturbing thought. Anyone –
anything –
could have detected that beacon, signalling to all the universe that Intelligence had once passed this way. He recalled that, a few years ago, there had been a move to switch off the transmission on the grounds that it served no useful purpose and might conceivably do harm. The motion had been rejected by a narrow margin, for reasons that were sentimental and emotional rather than logical. Thalassa might soon regret that decision, but it was certainly much too late to do anything about it.
