The Three-Body Problem

“Zero dimensions?” The princeps was interested. “Wouldn’t that be a point with no size?”

“Yes, a singularity! Even a proton would be infinitely big compared to it. The entire mass of the proton will be contained in this singularity, and its density will be infinite. Princeps, I’m sure you can imagine what that would be.”

“A black hole?”

“Yes.”

“Princeps, let me explain,” the science consul broke in. “The reason we picked a proton instead of a neutron to unfold into two dimensions is precisely to avoid this kind of risk. If we really were to unfold into zero dimensions, the charge of a proton would also be carried over into the unfolded black hole. We can then capture and control it using electromagnetism.”

“What if you can’t find it or control it?” the military consul asked. “It can then land on the ground, suck in everything it encounters, and increase its mass. Then it will sink into the core of this planet and eventually suck down all of Trisolaris.”

“That will never happen. I guarantee it! Why are you always making things difficult for me? Like I said, this is a scientific experiment—”

“That’s enough!” the princeps said. “What is the probability of success next time?”

“Almost one hundred percent! Princeps, please believe in me. Through these two failures, we have already mastered the principles governing unfolding subatomic structures into low-dimensional macro space.”

“All right. To ensure the survival of Trisolaran civilization, we must take this risk.”

“Thank you!”

“But if you fail again, you and all the scientists working on Project Sophon will be guilty.”

“Yes, of course, all guilty.” If Trisolarans could perspire, the science consul must have been soaked in cold sweat.

It was much easier to clean up the three-dimensional remnants of the unfolded proton in synchronous orbit than it was to clean up the one-dimensional string. Small spaceships were able to drag the pieces of proton matter away from Trisolaris and prevent them from entering the atmosphere. Those objects, some as large as mountains, had almost no mass. They were like immense silver illusions; even a baby could have moved them easily.

Afterwards, the princeps asked the science consul, “Did we destroy a civilization in the microcosmos in this experiment?”

“It was at least an intelligent body. Also, Princeps, we destroyed the entire microcosmos. That miniature universe is immense in higher dimensions, and it probably contained more than one intelligence or civilization that never had a chance to express themselves in macro space. Of course, in higher dimensional space at such micro scales, the form that intelligence or civilization may take is beyond our imagination. They’re something else entirely. And such destruction has probably occurred many times before.”

“Oh?”

“In the long history of scientific progress, how many protons have been smashed apart in accelerators by physicists? How many neutrons and electrons? Probably no fewer than a hundred million. Every collision was probably the end of the civilizations and intelligences in a microcosmos. In fact, even in nature, the destruction of universes must be happening at every second—for example, through the decay of neutrons. Also, a high-energy cosmic ray entering the atmosphere may destroy thousands of such miniature universes.… You’re not feeling sentimental because of this, are you?”

“You amuse me. I will immediately notify the propaganda consul and direct him to repeatedly publicize this scientific fact to the world. The people of Trisolaris must understand that the destruction of civilizations is a common occurrence that happens every second of every hour.”

“Why? Do you wish to encourage the people to face the possible destruction of Trisolaran civilization with equanimity?”

“No. It’s to encourage them to face the destruction of Earth civilization with equanimity. You know very well that after we publicized our policy toward the Earth civilization, there was a wave of extremely dangerous pacifism. We have only now discovered that there are many like the listener of Post 1379. We must control and eliminate these weak sentiments.”

“Princeps, this is mainly the result of recent messages received from the Earth. Your prediction has come true: The alienated forces on Earth really are growing. They have built a new transmission site completely under their control, and have begun to send us large amounts of information about Earth civilization. I must admit that their civilization has great appeal on Trisolaris. For our people, it sounds like sacred music from Heaven. The humanism of Earth will lead many Trisolarans onto the wrong path. Just as Trisolaran civilization has already become a religion on Earth, Earth civilization has this potential on Trisolaris.”

“You’ve pointed out a great danger. We must strictly control the flow of information from the Earth to the populace, especially cultural information.”
