Lamont was learning to compromise in more than one direction. He might have said that Chen was not the first to ask this, but it would have sounded condescending, perhaps impatient, and he chose not to do so.
Lamont said, “They were anxious to get started with something that was so apparently desirable as a source of energy, just as we were. I have reason to think they’re as disturbed about it now as I am.”
“That’s still your word. You have no definite evidence about their state of mind.”
“None that I can present at this moment.”
“Then it’s not enough.”
“Can we afford to risk—”
“It’s not enough, Professor. There’s no evidence. I haven’t built my reputation by shooting down targets at random. My missiles have sped true to the mark every time because I knew what I was doing.”
“But when I get the evidence—”
“Then I’ll back you. If the evidence satisfies me, I assure you neither Hallam nor the Congress will be able to resist the tide. So get the evidence and come see me again.”
“But by then it will be too late.”
Chen shrugged. “Perhaps. Much more likely, you will find that you were wrong and no evidence is to be had.”
“I’m not wrong.” Lamont took a deep breath, and said in a confidential tone, “Mr. Chen. There are very likely trillions upon trillions of inhabited planets in the Universe, and among them there may be billions with intelligent life and highly developed technologies. The same is probably true of the para-Universe. It must be that in the history of the two Universes there have been many pairs of worlds that came into contact and began Pumping. There may be dozens or even hundreds of Pumps scattered across junction points of the two Universes.”
“Pure speculation. But if so?”
“Then it may be that in dozens or hundreds of cases, the mixture of natural law advanced locally to an extent sufficient to explode a planet’s Sun. The effect might have spread outward. The energy of a supernova added to the changing natural law may have set off explosions among neighboring stars, which in turn set off others. In time perhaps an entire core of a galaxy or of a galactic arm will explode.”
“But that is only imagination, of course.”
“Is it? There are hundreds of quasars in the Universe; tiny bodies the size of several Solar systems but shining with the light of a hundred full-size ordinary galaxies.”
“You’re telling me that the quasars are what are left of Pumping planets.”
“I’m suggesting that. In the century and a half since they were discovered, astronomers have still failed to account for their sources of energy. Nothing in this Universe will account for it; nothing. Doesn’t it follow then—”
“What about the para-Universe? Is it full of quasars, too?”
“I wouldn’t think so. Conditions are different there. Para-theory makes it seem quite definite that fusion takes place much more easily over there, so the stars must be considerably smaller than ours on the average. It would take a much smaller supply of easily-fusing hydrogen to produce the energy our Sun does. A supply as large as that of our Sun would explode spontaneously. If our laws permeate the para-Universe, hydrogen becomes a little more difficult to fuse; the para-stars begin to cool down.”
“Well, that’s not so bad,” said Chen. “They can use Pumping to supply themselves with the necessary energy. By your speculations, they’re in fine shape.”
“Not really,” said Lamont. Until now, he hadn’t thought the para-situation through. “Once our end explodes, the Pumping stops. They can’t keep it up without us, and that means they’ll face a cooling star without Pump-energy. They might be worse off than we; we’d go out in a painless flash while their agony would be long-drawn-out.”
“You have a good imagination, Professor,” said Chen, “but I’m not buying it. I don’t see any chance of giving up Pumping on nothing more than your imagination. Do you know what the Pump means to mankind? It’s not just the free, clean, and copious energy. Look beyond that. What it means is that mankind no longer has to work for a living. It means that for the first time in history, mankind can turn its collective brains to the more important problem of developing its true potential.
“For instance, not all the medical advances of two and a half centuries have succeeded in advancing man’s full life-span much past a hundred years. We’ve been told by gerontologists over and over that there is nothing, in theory, to stand in
