Greg sat upright. “Say, what’s light got to do with this?”
“A lot,” said Russ. “All commerce is based on the assumption that light is instantaneous, but it isn’t. All business, anywhere throughout the Solar System, is based on Greenwich time. When a noon signal sent out from Earth reaches Mars, it’s noon there, but as a matter of fact, it is actually 15 minutes or so past noon. When the same signal reaches Callisto, the correct time for the chronometer used in commerce would be noon when it is really a quarter to one. That system simplifies things. Does away with varying times. And it has worked all right so far because there has been, up to now, nothing that could go faster than light. No news can travel through space, no message, no signal can be sent at any speed greater than that. So everything has been fine.”
Greg had come out of the chair, was standing on his feet, the glow of the blaze throwing his athletic figure into bold relief. That calm exterior had been stripped from him now. He was excited.
“I see what you are getting at! We have something that is almost instantaneous!”
“Almost,” said Russ. “Not quite. There’s a time lag somewhere. But it isn’t noticeable except over vast distances.”
“But it would beat ordinary light signals to Callisto. It would beat them there by almost 45 minutes.”
“Almost,” Russ agreed. “Maybe a split second less.”
Greg strode up and down in front of the fireplace like a caged lion. “By heaven,” he said, “we’ve got Chambers where we want him. We can beat the stock quotations to Callisto. With that advance knowledge of what the board is doing in New York, we can make back every dime I’ve lost. We can take Mr. Chambers to the cleaners!”
Russ grinned. “Exactly,” he said. “We’ll know 45 minutes in advance of the other traders what the market will be. Let’s see Chambers beat that.”
CHAPTER SEVEN
Ben Wrail was taking things easy. Stretched out in his chair, with his cigar lit and burning satisfactorily, he listened to a radio program broadcast from Earth.
Through the window beside him, he could look out of his skyscraper apartment over the domed city of Ranthoor. Looming in the sky, slightly distorted by the heavy quartz of the distant dome, was massive Jupiter, a scarlet ball tinged with orange and yellow. Overwhelmingly luminous, monstrously large, it filled a large portion of the visible sky, a sight that brought millions of tourists to the Jovian moons each year, a sight that even the old-timers still must stare at, drawn by some unfathomable fascination.
Ben Wrail stared at it now, puffing at his cigar, listening to the radio. An awe-inspiring thing, a looming planet that seemed almost ready to topple and crash upon this airless, frigid world.
Wrail was an old-timer. For thirty years — Earth years — he had made his home in Ranthoor. He had seen the city grow from a dinky little mining camp enclosed by a small dome to one that boasted half a million population. The dome that now covered the city was the fourth one. Four times, like the nautilus, the city had outgrown its shell, until today it was the greatest domed city in the Solar System. Where life had once been cheap and where the scum of the system had held rendezvous, he had seen Ranthoor grow into a city of dignity, capital of the Jovian confederacy.
He had helped build that confederacy, had been elected a member of the constitution commission, had helped create the government and for over a decade had helped to make its laws.
But now . . . Ben Wrail spat angrily and stuffed the cigar back in his mouth again, taking a fresh and fearsome grip. Now everything had changed. The Jovian worlds today were held in bond by Spencer Chambers. The government was in the hands of his henchmen. Duly elected, of course, but in an election held under the unspoken threat that Interplanetary Power would withdraw, leaving the moons circling the great planet without
