Judgment Day

It took me a long time to decide whether to let the earth live. Some might think this an easy decision. Well, it was and it wasn't. I wanted one thing, while the mores of my culture said to do the other.

This is the decision that few have to make. Hitler might give orders for the execution of ten million, and Stalin orders that would kill another ten million. But neither could send the world up in a puff of flame by a few marks on a piece of paper.

Only now has physics got to the point where such a decision is possible. Yet, with due modesty, I don't think my discovery was inevitable. Somebody might have come upon it later – say, in a few centuries, when such things might be better organized. My equation was far from obvious. All the last three decades' developments in nuclear physics have pointed away from it.

My chain reaction uses iron, the last thing that would normally be employed in such a series. It's at the bottom of the atomic energy curve. Anything else can be made into iron with a release of energy, while it takes energy to make iron into anything else.

Really, the energy doesn't come from the iron, but from the… the other elements in the reaction. But the iron is necessary. It is not exactly a catalyst, as it is transmuted and then turned back into iron again, whereas a true catalyst remains unchanged. But the effect is the same. With iron so common in the crust of the earth, it should be possible to blow the entire crust off with one big poof.

I recall how I felt when I first saw these equations, here in my office last month. I sat staring at my name on the glass of the door, "Dr. Wade Ormont," only it appears backward from the inside. I was sure I had made a mistake. I checked and rechecked and calculated and recalculated. I went through my nuclear equations at least thirty times. Each time my heart, my poor old heart, pounded harder and the knot in my stomach grew tighter. I had enough sense not to tell anybody else in the department about my discovery.

I did not even then give up trying to find something wrong with my equations. I fed them through the computer, in case there was some glaring, obvious error I had been overlooking. Didn't that sort of thing – a minus for a plus or something – once happen to Einstein? I'm no Einstein, even if I am a pretty good physicist, so it could happen to me.

However, the computer said it hadn't. I was right.

The next question was: What to do with these results? They would not help us toward the laboratory's objectives: more powerful nuclear weapons and more efficient ways of generating nuclear power. The routine procedure would be to write up a report. This would be typed and photostated and stamped "Top Secret." A few copies would be taken around by messenger to those who needed to know such things. It would go to the AEC and the others. People in this business have learned to be pretty close-mouthed, but the knowledge of my discovery would still spread, even though it might take years.

I don't think the government of the United States would ever try to blow up the world, but others might. Hitler might have, if he had known how, when he saw he faced inevitable defeat. The present Commies are pretty cold-blooded calculators, but one can't tell who'll be running their show in ten or twenty years. Once this knowledge gets around, anybody with a reasonable store of nuclear facilities could set the thing off. Most would not, even in revenge for defeat. But some might threaten to do so as blackmail, and a few could actually touch it off if thwarted. What's the proportion of paranoids and other crackpots in the world's population? It must be high enough, as a good fraction of the world's rulers and leaders have been of this type. No government yet devised-monarchy, aristocracy, theocracy, timocracy, democracy, dictatorship, soviet, or what have you – will absolutely stop such people from coming to the top. So long as these tribes of hairless apes are organized into sovereign nations, the nuclear Ragnarok is not only possible but probable.

For that matter, am I not a crackpot myself, calmly to contemplate blowing up the world?

No. At least the psychiatrist assured me my troubles were not of that sort. A man is not a nut if he goes about gratifying his desires in a rational manner. As to the kind of desires, that's nonrational anyway. I have adequate reasons for wishing to exterminate my species. It's no high-flown farfetched theory either; no religious mania about the sinfulness of man, but a simple, wholesome lust for revenge. Christians pretend to disapprove of vengeance, but that's only one way of looking at it. Many other cultures have deemed it right and proper, so it can't be a sign of abnormality.

For instance, when I think back over my fifty-three years, what do I remember? Well, take the day I first entered school…
