"The Three-Body Problem" — Correspondence to the Inhabitants of Trisolaris

Greetings, inhabitants of the planet Trisolaris.

I accidentally found myself in your world, over which three stars hang. Life on your planet is more cruel than on my homeland. You have three stars, and their path is complex and unpredictable. But if life on your planet is alive, if intelligence has grown on it, then the chaos of your stars is not boundless, and there is magic of order within it. And I have brought you an observation that can be verified.

Take three stars at a single moment. Through them, a celestial plane can be drawn. Take three such planes at three close moments in time: the day before yesterday, yesterday, today. Any two planes intersect in a line. Three lines converge at a single point — let us call it the Eye of Trimurti.

• When the Eye moves slowly, the celestial planes are in harmony. This is the Stable Era. Then you can build, sow, teach children, and prepare supplies.
• When the Eye begins to accelerate, the pattern loses its strength. It may still be light and warm, but this is the wind before the storm. It is time to prepare for dehydration.
• When the Eye goes beyond the horizon, the old rules cease to apply. The Chaotic Era begins. The former calendars must be burned — not with anger, but as tools that have served their purpose. You must sleep, preserve knowledge, and wait.
• When the Eye returns from the opposite side, a new epoch begins. This is important to remember — this is the only thread stretching from the old world into the new. What once gave warmth may become cold; what was a threat may become a support.

The Eye of Trimurti does not know your personal fate. It is merely a marker that shows the strength of the ice. The marker does not know who exactly will fall through, but it knows that the ice is unreliable.

Let your sages record the path of the Eye of Trimurti every day — how fast it moves, where it is heading, when it disappears, and from where it returns. Over generations, these records will become legends from simple words:

• Eye is calm — live and build Krishna
• Eye accelerates — prepare Rama
• Eye disappears — dehydrate Shiva
• Eye has returned — begin a new life Brahma

This is the magic of geometry, turned into protection. The three stars only seem mad. But that which can be measured ceases to be madness. And when you learn to understand the sky, you will remember a simple thought: even in chaos, there is form — for those who know how to look.

With respect to your sky,

Hyperborea from the planet Solaris.
