The Sentinel - Arthur C. Clarke [14]
To that question he was never to know the answer, though he might have guessed it had he known that the chillingly remote Paladorian mind possessed an almost human streak of vanity. Long ago, Alarkane had written a book trying to prove that eventually all intelligent races would sacrifice individual consciousness and that one day only group-minds would remain in the Universe. Palador, he had said, was the first of those ultimate intellects, and the vast, dispersed mind had not been displeased.
They had no time to ask any further questions before Alveron himself began to speak through their communicators.
“Alveron calling! We’re staying on this planet until the detonation waves reach it, so we may be able to rescue you. You’re heading toward a city on the coast which you’ll reach in forty minutes at your present speed. If you cannot stop yourselves then, we’re going to blast the tunnel behind and ahead of you to cut off your power. Then we’ll sink a shaft to get you out —the chief engineer says he can do it in five minutes with the main projectors. So you should be safe within an hour, unless the sun blows up before.”
“And if that happens, you’ll be destroyed as well! You mustn’t take such a risk!”
“Don’t let that worry you; we’re perfectly safe. When the sun detonates, the explosion wave will take several minutes to rise to its maximum. But apart from that, we’re on the night side of the planet, behind an eight-thousand-mile screen of rock. When the first warning of the explosion comes, we will accelerate out of the Solar System, keeping in the shadow of the planet. Under our maximum drive, we will reach the velocity of light before leaving the cone of shadow, and the sun cannot harm us then.”
T’sinadree was still afraid to hope. Another objection came at once into his mind.
“Yes, but how will you get any warning, here on the night side of the planet?”
“Very easily,” replied Alveron. “This world has a moon which is now visible from this hemisphere. We have telescopes trained on it. If it shows any sudden increase in brilliance, our main drive goes on automatically and we’ll be thrown out of the system.”
The logic was flawless. Alveron, cautious as ever, was taking no chances. It would be many minutes before the eight-thousand-mile shield of rock and metal could be destroyed by the fires of the exploding sun. In that time, the S9000 could have reached the safety of the velocity of light.
Alarkane pressed the second button when they were still several miles from the coast. He did not expect anything to happen then, assuming that the machine could not stop between stations. It seemed too good to be true when, a few minutes later, the machine’s slight vibration died away and they came to a halt.
The doors slid silently apart. Even before they were fully open, the three had left the compartment. They were taking no more chances. Before them a long tunnel stretched into the distance, rising slowly out of sight. They were starting along it when suddenly Alveron’s voice called from the communicators.
“Stay where you are! We’re going to blast!”
The ground shuddered once, and far ahead there came the rumble of falling rock. Again the earth shook—and a hundred yards ahead the passageway vanished abruptly. A tremendous vertical shaft had been cut clean through it.
The party hurried forward again until they came to the end of the corridor and stood waiting on its lip. The shaft in which it ended was a full thousand feet across and descended into the earth as far as the torches could throw their beams. Overhead, the storm clouds fled beneath a moon that no man would have recognized, so luridly brilliant was its disk. And, most glorious of all sights, the S9000 floated high above, the great projectors that had drilled this enormous pit still glowing cherry red.
A dark shape detached itself from the mother ship and dropped
