The Gods Themselves by Isaac Asimov Page A

make sense and seems to make no trouble, but what if it is not matter that offers resistance to the permeation of the alien laws, but the basic fabric of the Universe itself."
    "What is the basic fabric?"
    "I can't put it in words. There is a mathematical expression which I think represents it, but I can't put it into words. The basic fabric of the Universe is that which dictates the laws of nature. It is the basic fabric of our Universe that makes it necessary for energy to be conserved. It is the basic fabric of the para-Universe, with a weave, so to speak, somewhat different from ours, that makes their nuclear interaction a hundred times stronger than ours."
    "And so?"
    "If it is the basic fabric that is being penetrated, sir, then the presence of matter, dense or not, can have only a secondary influence. The rate of penetration is greater in a vacuum than in dense mass, but not very much greater. The rate of penetration in outer space may be great in Earthly terms but it is only a small fraction of the speed of light."
    "Which means?"
    "That the alien fabric is not dissipating as quickly as we think, but is piling up, so to speak, within the Solar system to a much greater concentration than we have been assuming."
    "I see," said the senator, nodding his head. "And how long then will it be before the space within the Solar system is brought to equilibrium? Less than, 1080years, I imagine."
    "Far less, sir. Less than 1010years, I think. Perhaps fifty billion years, give or take a couple of billion."
    "Not much in comparison, but enough, eh? No immediate cause for alarm, eh?"
    "But I'm afraid that is immediate cause for alarm, sir. Damage will be done long before equilibrium is reached. Because of the Pumping, the strong nuclear interaction is growing steadily stronger in our Universe at every moment."
    "Enough stronger to measure?"
    "Perhaps not, sir."
    "Not even after twenty years of Pumping?"
    "Perhaps not, sir."
    "Then why worry?"
    "Because, sir, upon the strength of the strong nuclear interaction rests the rate at which hydrogen fuses to helium in the core of the Sun. If the interaction strengthens even unnoticeably, the rate of hydrogen fusion in the Sun will increase markedly. The Sun maintains the balance between radiation and gravitation with great delicacy and to upset that balance in favor of radiation, as we are now doing—"
    "Yes?"
    "—will cause an enormous explosion. Under our laws of nature, it is impossible for a star as small as the Sun to become a supernova. Under the altered laws, it may not be. I doubt that we would have warning. The Sun would build up to a vast explosion and in eight minutes after that you and I will be dead and the Earth will quickly vaporize into an expanding puff of vapor."
    "And nothing can be done?"
    "If it is too late to avoid upsetting the equilibrium, nothing. If it is not yet too late, then we must stop Pumping."
    The senator cleared his throat. "Before I agreed to see you, young man, I inquired as to your background since you were not personally known to me. Among those I queried was Dr. Hallam. You know him, I suppose?"
    "Yes, sir." A corner of Lament's mouth twitched but his voice held even. "I know him well."
    "He tells me," said the senator, glancing at a paper on his desk, "that you are a troublemaking idiot of doubtful sanity and he demands that I refuse to see you."
    Lament said in a voice he strove to keep calm. "Are those his words, sir?"
    "His exact words."
    "Then why have you agreed to see me, sir?"
    "Ordinarily, if I received something like this from Hal-lam, I wouldn't have seen you. My time is valuable and heaven knows I see more troublemaking idiots of doubtful sanity than bears thinking of, even among those who come to me with the highest recommendations. In this one case, though, I didn't like Hallam's 'demand.' You don't make demands of a senator and Hallam had better learn that."
    "Then you will help me, sir?"
    "Help you do what?"
    "Why—arrange to have
