Dark Matter/Simulation 13
What the equations test
Ten scenes. Two minutes fifty-four. The spherical model through Simulation 13 — formation from a near-zero retained state, the tests that fail, and the one that holds a curve flat. A research hypothesis. Not an established result.

01 · 0:00
Memory
A core point appears. A spectral thread grows. Spacetime keeps a memory.
02 · 0:14
Source
Ordinary matter writes memory into the space around it. Density n. Source rate Q̇.
03 · 0:30
Transport
Nothing is created or lost. What flows in through one shell must flow out through the next.
04 · 0:46
Forces
Pressure out. Gravity in. A sonic point at about twelve kiloparsecs. A wind is born.
05 · 1:04
Emergence
Visible matter falls away. Memory thins as r⁻². The rotation curve goes flat at 160 km/s.
06 · 1:24
Collapse
Test one. If memory weighs like matter, the halo collapses.
07 · 1:42
Trade-off
Test two. A hotter wind survives, but leaves too little to hold the disc.
08 · 1:58
Balance
Test three. Feed it faster. Flat to 120 kpc — at four thousand suns a year.
09 · 2:14
Coupling
Test four. Enclosed coupling holds. Point-by-point coupling fails.
10 · 2:34
Open
Every test assumed a sphere. Simulation 14 asks what survives without one.
What you are watching
The animation is a reading of the Simulation 13 working, not a proof. Ordinary matter at the core writes a retained state into spacetime. That state is carried outward — conserved, not created on the way. Where outflow meets the sound barrier a wind is born. Left alone, the memory thins as one over distance squared, which is the shape that holds a rotation curve flat.
The tests that follow are failure modes. Self-gravity collapses the halo. A hotter wind survives and starves the disc. Faster feeding holds the curve at a steep source cost. Coupling counted as a whole can hold; counted point by point, the core runs away.
Full covariant formulation, realistic galaxy morphology, lensing, cosmology and cluster behaviour remain outstanding. Simulation 14 will test whether any of this survives without spherical symmetry.
