POWERS OF CREATION — SCIENCE AND CREDITS
Cinematic v2 | source review, 2 November 2026

WHAT THIS FILM IS
An illustrative journey across representative length scales, produced locally
with Python, Blender/Cycles and FFmpeg in the Engines of Creation worktree.
It combines authored, editable Blender scenes with deposited DNA coordinates,
NASA Earth texture composites and NASA's observed solar time-lapse footage.
The scene compositions, materials, cameras, animation, type and editing were
created for this project. Scientific source data and observations retain the
attribution given below.

This is a local production demo, not evidence of a hosted website autonomously
creating these assets. It should not be described as entirely generated imagery:
the film's Sun chapter is observed NASA footage, and other scenes use the
credited scientific data. Attribution does not imply NASA, RCSB PDB, wwPDB,
MIT, NIST or another institution endorses or is affiliated with the project.

Subjects are individually reframed. Their apparent screen sizes and chapter
transitions do not depict one physically continuous zoom, a real camera route,
or objects occupying the same location. Materials, color, light, particle size,
motion and timing are composed for communication rather than calibrated physics.

1. CELL — AUTHORED BIOLOGICAL ILLUSTRATION
The approximate 20-micrometre diameter is a representative animal-cell scale;
cell types vary substantially. The scene is a generic cutaway, not a measured
specimen, a cell-type-specific reconstruction, or microscope footage.
Membranes, nucleus, nucleolus, chromatin, mitochondrial folds, ER, Golgi,
cytoskeleton and vesicles are procedurally modeled. Nuclear pores, ribosome-like
forms, nucleosome-like granules and crowded cytosolic particles are geometric
stand-ins, not meshes segmented from tomography or experimentally determined
protein/enzyme structures. Their number, arrangement, relative dimensions,
colors, opacity and surface relief are illustrative. The rendering of a
participating medium is a visual treatment, not a quantitative cytoplasm model.
On-screen qualifiers: "TYPICAL DIAMETER" and "Illustrative cutaway".

2. DNA — EXPERIMENTAL COORDINATES, AUTHORED DISPLAY
The DNA model uses PDB 1BNA: the synthetic Drew–Dickerson dodecamer, an
experimentally determined right-handed B-DNA duplex. The deposited structure
has 12 base pairs, two antiparallel strands, and sequence CGCGAATTCGCG on
each strand in the 5'-to-3' direction. It was determined by X-ray diffraction
at 1.90 angstrom resolution.
The current builder reads the 486 DNA heavy-atom coordinates from the supplied
JSON, recenters them, applies a proper rotation and uniformly scales them.
Those operations preserve geometry and handedness. It does not invent a long
repeat helix or wrap this fragment around a curve. Eighty deposited water
oxygens remain separate in the source JSON and are not rendered; the deposited
file has no hydrogen atoms.
The display uses spheres and bond cylinders. Their radii, colors, gloss,
lighting and rigid-body motion are authored choices. This is not a literal
electron-density image, photographic molecular color, calibrated space-filling
surface or molecular-dynamics trajectory. Covalent connectivity is derived from
the wwPDB chemical component dictionaries plus standard consecutive backbone
links, as documented in molecular-sources.txt; all bond cylinders are a visual
simplification of the retained bond-order metadata.
The approximate 2 nm label refers to duplex width, not this fragment's length.

3. HYDROGEN — QUALITATIVE QUANTUM VISUALIZATION
A neutral hydrogen atom has one electron. The many plotted points represent
possible sample locations for that one electron, not thousands of electrons
present simultaneously and not a recorded electron trajectory. The diffuse
spherical cloud is intended to evoke the hydrogen 1s probability distribution;
there are no planetary electron-orbit tracks.
The proton is deliberately enlarged. The approximate 0.1 nm characteristic
scale is about two Bohr radii; it is not a sharp atomic boundary. Real 1s
probability density decays with distance and has no hard outer surface.
In the illustration, the exponential volume and point sampling use separately
tuned scales and a finite display cutoff. Brightness, scattering and point
sizes are not a normalized or quantitatively calibrated probability plot.
The narrative "A cloud of possibility" accompanies the explicit on-screen
"1s probability illustration" and "Proton enlarged for visibility" labels.
Preserve that context: an orbital is not a classical hollow shell, electron
probability does not vanish outside the nucleus, and the illustration is not
a statement that matter is optically transparent.

4. EARTH — NASA COMPOSITES ON AN AUTHORED GLOBE
The scene maps NASA's Blue Marble day and cloud imagery onto an authored sphere
with separate cloud and atmosphere layers. These are historical composites,
not live weather, a single exposure, or a measured atmosphere volume. NASA's
land/coastal observations were collected in June–September 2001; the cloud
product combines visible and polar thermal-infrared observations over multiple
days. The day map includes topographic shading. Optical roughness, cloud-shell
height, opacity, atmospheric scattering and rotation are visualization choices.
The 12,742 km label is the rounded mean diameter, based on approximately
6,371 km mean radius; it is not the larger equatorial diameter.

docs/molecular-sources.txt. The originals are 21600×10800 and 8192×4096 pixels.

5. SUN — OBSERVED FOOTAGE IN THE FILM
The film uses NASA SDO's "Active Region Conga Line" sequence, observed
September 22–24, 2012 in the AIA 171-angstrom (17.1 nm) channel. This is an
extreme-ultraviolet view of coronal structures rendered in false color, not the
Sun's visible-light appearance, photospheric granulation, or simulated plasma.
The original 3840×2160, 25 fps, 14.04-second time-lapse is cropped for portrait
composition and retimed to six seconds at 24 fps. This accelerates an already
accelerated observational sequence; playback seconds are not exposure times.
The published date range is retained without inventing exact exposure times.
No artificial inter-frame motion is required by the current finisher.

SEPARATE SUN.BLEND ASSET
The editable sun.blend is an authored sphere with a projected observed AIA
171-angstrom still, stamped 2026-11-02 06:55:58 UT. It is not the 2012 movie,
does not reconstruct the three-dimensional corona, and supplies no observed
far-side coverage. Its small rotation is authored staging. The two dates refer
to different source assets and must not be combined into one observation claim.
Stable still source:

Complete still/movie provenance and checksums: assets/sun/SOURCES.txt and JSON.
The unused procedural _sun() function retained in planetary.py is not the
selected build_planetary('sun') path and is not the film's solar source.

6. GALAXY — REPRESENTATIVE MILKY WAY ILLUSTRATION
The galaxy is an authored spiral-galaxy representation: an original 2048×2048
turbulent light/extinction texture on a warped disk, two asymmetric dominant
arms with weaker fragmented secondary structure, volumetric depth and tiny
instantiated stars.
It is not a photograph of the Milky Way from outside, an imported telescope
image, a reconstruction of individual measured stars, or a dynamical galaxy
simulation. Arm placement, light, dust, color and animation are illustrative.
The approximately 100,000-light-year scale refers to the stellar disk; definitions
of the disk's extent vary and the larger halo is not included. The preceding
"One star" and following "Among hundreds of billions" refer to the Sun within
the Milky Way's stellar population, not a precise count of rendered objects.
NASA's educational reference gives approximately 100–400 billion stars:

7. COSMIC WEB — AUTHORED DENSITY FIELD
The current source constructs a deterministic 128×128×128 illustrative density
field from thin Gaussian filaments, clusters and smooth perturbations, then
renders it as a single continuous volume with fine three-dimensional density
noise and embedded galaxy markers. The field and its 128-slice texture atlas
are generated locally. This is not observational survey
data, an N-body/cosmological simulation, a map of our actual cosmic surroundings,
or a visible-light image of dark matter. The density and warm/cool colors are
compositional encodings, not measured mass, gas temperature or spectral color.
Points in this scene represent galaxies, whereas the galaxy scene's points
represent stars. The rendering container is a numerical boundary, not an edge
or shell around the universe. It carries no claim about the size of the entire
universe. Preserve "Illustration · not an observational map" on screen.

LOCAL REPRODUCIBLE WORKFLOW
Editable assets: scenes/cell.blend, dna.blend, atom.blend, earth.blend,
sun.blend, galaxy.blend and web.blend. They retain authored geometry/materials,
animation and referenced scientific assets. Use the accompanying asset folders
and matching Blender environment when rebuilding; exact pixels can depend on
renderer, hardware and denoiser versions.

No paid inference or hosted autonomous generation is implied by this workflow.

REVIEW STATUS AND HANDOFF
Reviewed the current model-building source, film copy, finishing labels, source
metadata and local asset paths. The current labels are appropriate for the
illustrative framing and qualifications above. This is a source/provenance
review; the render queue and final assembled film require their own visual QA.
No GPU rendering was invoked for this review.
The film starts directly on picture and uses hard chapter cuts; only the final
web picture fades to black in the last quarter-second. Caption alpha fades
remain independent of the picture. Upper narrative is regular-weight text
over a readability scrim. docs/cosmic-design.txt describes the current warped
galaxy disk and single 128-cubed web field; obsolete construction counts have
been removed. Current instance counts are generated by cosmic.py and stored
as properties on each scene's root object, not treated as scientific counts.
