All were descendants of a mixed race with Latin, Semitic, Hamitic, and negroid ancestry: a race that had dwelt, before the sun’s cooling, in countries south of the Mediterranean, where the former deserts had been rendered fertile by a vast irrigation-system of lakes and canals.
This mixture, after so many centuries of cavern life, had produced a characteristically slender, well-knit type, of short or medium stature and pale olive complexion. The features were often of negroid softness, the general physique was marked by a delicacy verging upon decadence.
To an extent surprising, in view of the vast intermediate eras of historic and geographic change, this people had preserved many preatomic traditions and even something of the old classic Mediterranean cultures. Their language bore distinct traces of Latin, Greek, Spanish and Arabic.
Remnants of other peoples, those of sub-equatorial Asia and America, had survived the universal glaciation by burrowing underground. Radio communication had been maintained with these peoples till within fairly recent times, and had then ceased. It was believed that they had died out, or had retrograded into savagery, losing the civilization to which they had once attained.
Hour after hour, intervaled only by sleep and eating, the Phosphor sped onward through the black unvarying void. To Hilar, it seemed at times that they flew merely through a darker and vaster cavern whose remote walls were spangled by the stars as if by radiant orbs. He had thought to feel the overwhelming vertigo of unbottomed and undiretioned space. Instead, there was a weird sense of circumscription by the ambient night and emptiness, together with a sense of cyclic repetition, as if all that was happening had happened many times before and must recur often through endless future kalpas.
Had he and his companions gone forth in former cycles to the relighting of former perished suns? Would they go forth again, to rekindle suns that would flame and die in some posterior universe? Had there always been, would there always be, a Rodis who awaited his return? Of these thoughts he spoke only to Han Joas, who shared something of his innate mysticism and his trend toward cosmic speculation. But mostly the two talked of the mysteries of the atom and its typhonic powers, and discussed the problems with which they would shortly be confronted.
The ship carried several hundred disruption bombs, many of untried potency: the unused heritage of ancient wars that had left chasm scars and lethal radioactive areas, some a thousand miles or more in extent, for the planetary glaciers to cover. There were bombs of iron, calcium, sodium, helium, hydrogen, sulphur, potassium, magnesium, copper, chromium, strontium, barium, zinc: elements that had all been ancientily revealed in the solar spectrum. Even at the apex of their madness, the warring nations had wisely refrained from employing more than a few such bombs at any one time. Chain-reactions had sometimes been started; but, fortunately, had died out. Hilar and Han Joas hoped to distribute the bombs at intervals over the sun’s entire circumference; preferably in large deposits of the same elements as those of which they were composed. The vessel was equipped with radar apparatus by which the various elements could be detected and located. The bombs would be timed to explode with as much simultaneity as possible. If all went well, the Phosphor would have fulfilled its mission and traveled most of the return distance to earth before the explosions occurred.
It had been conjectured that the sun’s interior was composed of still- molten magma, covered by a relatively thin crust: a seething flux of matter that manifested itself in volcanic activities. Only one of the volcanoes was visible from earth to the naked eye; but numerous others had been revealed to telescopic study. Now, as the Phosphor drew near to its destination, the others flamed out on the huge, slowly rotating orb that had darkened a fourth of the ecliptic and had blotted Libra, Scorpio and Sagittarius wholly from view.
For a long time it had seemed to hang above the voyagers. Now, suddenly, as if through some prodigious legerdemain, it lay beneath them: a monstrous, ever-broadening disk of ebon, eyed with fiery craters, veined and spotted and blotched with unknown pallid radioactives. It was like the buckler of some macrososmic giant of the night, who had entrenched himself in the abyss lying between the worlds.
The Phosphor plunged toward it like a steel splinter drawn by some tremendous lodestone.
Each member of the crew had been trained before-hand for the part he was to play; and everything had been timed with the utmost precision. Sybal and Samac, the engineers of the anti-gravity magnets, began to manipulate the switches that would build up resistance to the solar drag. The generators, bulking to the height of three men, with induction-coils that suggested some colossal Laocoon, could draw from cosmic space a negative force capable of counteracting many earth-gravities. In past ages they had defied easily the pull of Jupiter; and the ship had even coasted as near to the blazing sun as its insulation and refrigeration systems would safely permit. Therefore it seemed reasonable to expect that the voyagers could accomplish their purpose of approaching closely to the darkened globe, of circling it, and pulling away when the disruption-charges had all been planted.
A dull, subsonic vibration, felt rather than heard, began to emanate from the magnets. It shook the vessel, ached in the voyagers’ tissues. Intently, with anxiety unbetrayed by their impassive features, they watched the slow, gradual building-up of power shown by gauge-dials on which giant needles crept like horologic hands, registering the reversed gravities one after one, till a drag equivalent to that of fifteen Earths had been neutralized. The clamp of the solar gravitation, drawing them on with projectile-like velocity, crushing them to their seats with relentless increase of weight, was loosened. The needles crept on . . . more slowly now . . . to sixteen . . . to seventeen . . . and stopped. The Phosphor’s fall had been retarded but not arrested. And the switches stood at their last notch.
Sybal spoke, in answer to the unuttered questions of his companions. “Something is wrong. Perhaps there has been some unforeseen deterioration of the coils, in whose composition strange and complex alloy were used. Some of the elements may have been unstable–or have developed instability through age. Or perhaps there is some interfering force, born of the sun’s decay. At any rate, it is impossible to build more power toward the twenty-seven antigravities we will require close to the solar surface.”
Samac added: “The decelerative jets will increase our resistance to nineteen anti-gravities. It will still be far from enough, even at our present distance.”
“How much time have we ?” inquired Hilar, turning to the navigators, Calaf and Caramod.
The two conferred and calculated.
“By using the decelerative jets, it will be two hours before we reach the sun,” announced Calaf finally.
As if his announcement had been an order, Eibano, the jet-engineer, promptly jerked the levers that fired to full power the reversing rockets banked in the Phosphor’s nose and sides. There was a slight further deceleration of their descent, a further lightening of the grievious weight that oppressed them. But the Phosphor still plunged irreversibly sun-ward.
Hilar and Han Joas exchanged a glance of understanding and agreement. They rose stiffly from their seats, and moved heavily toward the magazine, occupying fully half the ship’s interior, in which the hundreds of disruption-bombs were racked. It was unnecessary to announce their purpose; and no one spoke either in approval or demur.
Hilar opened the magazine’s door; and he and Han Joas paused on the threshold, looking back. They saw for the last time the faces of their fellow-voyagers, expressing no other emotion than resignation, vignetted, as it were, on the verge of destruction. Then they entered the magazine, closing its door behind them.
They set to work methodically, moving back to back along a narrow aisle between the racks in which the immerse ovoid bombs were piled in strict order according to their respective elements. Because of various coцrdinated dials and switches involved, it was a matter of minutes to prepare a single bomb for the explosion. Therefore Hilar and Han Joas, in the time at their disposal, could do no more than set the timing and detonating mechanism of one bomb of each element. A great chronometer, ticking at the magazine’s farther end, enabled them to accomplish this task with precision. The bombs were thus timed to explode simultaneously, detonating the others through chain-reaction, at the moment when the Phosphor should touch the sun’s surface.
The solar pull, strengthening as the Phosphor fell to its doom, had now made their movements slow and difficult. It would, they feared, immobilize them before they could finish preparing a second series of bombs for detonation. Laboriously, beneath the burden of a weight already trebled, they made their way to seats that faced a reflector in which the external cosmos was imaged.
