Terrena: A World Born from a Quantum ComputerThe birth of a planet, from the Big Bang to the year 2617
▶ Birth of Terrena, 86 s, silent. Every stage is a procedural visualization driven by the quantum seed: the real Tuna-17 bitstrings, then the Big Bang, the CMB, the cosmic web, the galaxy, the star Kestrel, the disk, the young planet, life and, finally, the civilization of 2617.
A new world, 1.03 Earths in mass, under a Sun-like star, drawn from 1,024 quantum measurements.
How this was made
- Real Quantum job. The circuit put a Hadamard gate on all 17 qubits of Tuna-17 and measured them. It ran 1,024 shots, and 1,017 of the bitstrings were unique.
- Real Seed. The sorted measurement counts were hashed with SHA-256 into one 256-bit seed: 2a9a2c6a…
- Simulated Classical simulation. The seed drove a NumPy random generator, which picked the cosmology, the galaxy, the star and the planet using textbook physics (a Friedmann integral, Kepler’s third law, habitable-zone fluxes and a mass-radius relation).
- Procedural Visuals. The video and renders were drawn from those parameters, and the glitter positions come straight from the shot bitstrings.
- Speculative Story. Life, the climate narrative and the civilization of 2617 are imaginative worldbuilding that stays consistent with the numbers. The cyan palette is an artistic choice.

With 131,072 possible outcomes, a few repeats are expected by chance, which is what an ideal random source produces. The same counts always rebuild the same world.
Where is Terrena?
In its own universe: Terrena orbits the star Kestrel at 1.125 AU. Kestrel lies in a 2-arm spiral galaxy, 23,480 light-years from the center, about 45% of the way out, in the galactic habitable zone.
From Earth: there is no real distance. Terrena exists in a separate simulated universe, so no telescope could find it.
Hypothetical If its galaxy were the Milky Way, then with the seeded angle of 59.9° around the center, Kestrel would be ≈25,212 light-years from Earth.
| Traveler (fictional) | Time |
|---|---|
| Light or radio | 25,212 years |
| Ship at 10% of light speed | ≈252,000 years |
| Ship at 50% of light speed | ≈50,400 years (≈43,700 for the crew) |
Civilization in 2617 Speculative worldbuilding
In this story, Terrena’s 12.9 billion people live mostly in 115 coastal arcology cities. That leaves the dark-teal interiors rewilded, and at night the coastlines glow cyan. A 63-terawatt fusion grid powers an orbital ring 794 km up. Three space elevators rise from the equator through the ring to shipyards in synchronous orbit at about 39,300 km. The single large moon, 333,000 km out, holds the helium-3 refineries and deep-space telescopes.
The numbers were drawn from the same seed, and the narrative is fiction built around them.
The ten stages of the birth video
The real Tuna-17 bitstrings stream in, and the per-bit bars and the SHA-256 seed are computed from the actual counts.
A bright point expands, and the seed sets the particle directions.
Light escapes at z ≈ 1088 and leaves a speckled, seeded CMB-like map. This is a procedural field, not real CMB data.
Dark-matter filaments form from a seeded density field (Zel’dovich approximation).
A 2-arm spiral with an 11.4° pitch assembles, and the camera zooms to 23.5 kly from the core.
A molecular cloud collapses, and the protostar ignites and launches jets.
Planetesimals near 1.13 AU clump into proto-Terrena.
A magma ocean cools into a basalt crust, and oceans rise to 64.7% coverage.
Clouds form, a cyan halo appears, and life colors the land dark teal.
The night side shows cyan cities, the neon orbital ring and the elevators.
The measured bits Real data
The first chart shows the fraction of 1s on each of the 17 qubits across the 1,024 real shots. Deviations of a few percent are normal readout bias on current noisy hardware, and SHA-256 mixes every bit, so the bias does not affect the seed. The second chart is a histogram of the measured 17-bit values. 7 bitstrings appeared twice, in line with an ideal uniform source.
Climate, geology and life Speculative worldbuilding
Climate. With 1.04 times Earth’s sunlight, a 23.7° tilt and a 421-day year, Terrena would have Earth-like seasons that each last about 15% longer. The 26.6-hour day would slightly soften the swing between day and night. A mean near 18 °C would suggest small polar caps and broad temperate zones.
Geology. At 1.03 Earth masses and 5.54 g/cm³, Terrena would plausibly have an iron core, a convecting mantle, plate tectonics and a magnetic field. Its large moon, which orbits closer in than ours, would raise strong tides and help stabilize the tilt.
Life. In this story, life begins in tidal shallows. Photosynthesis raises oxygen to the modeled 19.7%, and land plants use a teal-shifted pigment tuned to Kestrel’s slightly hotter light. The glowing cyan oceans are an artistic brand choice, not a physical prediction.
Methods and limits
Quantum The only thing the quantum computer contributed was the random seed, from real Tuna-17 hardware job 1476038. No emulator output was used.
Classical Python and NumPy with a PCG64 generator seeded by the SHA-256 digest, drawing values around those of the real universe. The age comes from a Friedmann integral. The star uses L ∝ M⁴ and R ∝ M0.8, with Kopparapu-style habitable-zone fluxes, a rocky mass-radius relation, Kepler’s third law, and an equilibrium temperature plus a simple greenhouse term.
Procedural A NumPy and Pillow renderer made the video and stills.
A 17-qubit processor cannot simulate physics at cosmic scale, and nothing here claims it did. The quantum job supplied true randomness, and everything else is transparent classical computation that anyone can rerun from the seed.

City: Qirport Speculative worldbuilding
In this story, Qirport is a terraced crescent city that follows the shoreline of a fjord coast at 20° south. Its 60.5 million people live among 4 arcologies and about 2,014 towers. A typical tower stands near 400 m, and the Glass Spire rises 2,013 m. Three sky districts are linked by skybridges between the arcology crowns. A 98 km elevated maglev loop, autonomous harbour ferries and a suborbital shuttle port connect the city to the equatorial space elevators.
Landmarks: the Starwater Promenade, a bioluminescent seawall; the Tuna Archive, a planetary data vault said in legend to hold the “first seed”; and Zenith Plaza, with the best view of the orbital ring.
Inhabitants: the Nethrai Speculative worldbuilding
The Nethrai are slender and long-limbed, about 1.93 m tall, with two arms and two digitigrade legs. Their skin is a smooth deep teal with a pearlescent sheen. Twin glowing cyan stripes run from brow to heel, and freckle-like glints dot the cheeks and shoulders. Large dark eyes with cyan-ringed irises are suited to Kestrel’s light and the long 13.3-hour nights.
They wear layered translucent robes woven from light-guiding fibre, and they use wrist-worn holo-lattices and personal grav-skiffs. Nethrai greet each other by synchronising glow pulses. Every night their cities hold the Glitter Tide, when millions of photophores flash in unison. They live about 159 years.
No real beings were observed or detected. The species is fiction generated from the mission seed.
