Cosmology
Derive the cosmic microwave background spectrum, anisotropies, polarization, acoustic structure, and large-scale anomalies from Great Collision initial conditions.
The Problem
HGUT must turn its Great Collision narrative into a quantitative cosmological prediction. The model must derive the thermal history, perturbation spectrum, radiation transport, angular power spectra, polarization, damping, lensing, and any distinctive relic signatures from the post-collision state.
Scientific Importance
The CMB is one of the most information-rich tests of early-universe physics. Qualitative resemblance is insufficient; HGUT must reproduce the measured structure or provide a quantitatively superior alternative.
Progress Ledger
The CMB has been proposed as a possible relic or diagnostic of the Great Collision.
The collision narrative offers candidate sources of asymmetry and initial structure.
No full Boltzmann-level prediction or fit to temperature and polarization spectra has yet been completed.
Pass-or-Fail Structure
Every gate must be addressed before this problem can be considered closed. Partial success does not establish the complete identification.
Derive the homogeneous thermal and expansion history after the collision.
Derive the amplitude, spectrum, statistics, and mode content of initial fluctuations.
Recover the radiation and matter history leading to last scattering.
Compute TT anisotropies, acoustic peaks, and damping tail.
Compute TE, EE, possible BB structure, and lensing effects.
Identify collision-specific anomalies or nonstandard correlations.
Definition of Success
This problem closes only when the following conditions are satisfied together.
Great Collision simulations supply quantitative cosmological initial conditions.
The thermal and perturbation histories are derived consistently.
Temperature and polarization spectra are computed from the model.
Peak positions, heights, damping, and lensing agree with observations within stated precision.
Large-scale anomalies are addressed without post hoc tuning.
Any distinctive collision relics are explicit, quantitative, and testable.
Model comparison against standard cosmology is performed transparently.
Prerequisites
Open Collaboration
Connected Research
Cosmology
Simulate the collision of the pre-universe structures and determine whether the event produced a rebound, complete merger, partial merger, fragmentation, or another outcome.
Light and Transport
Derive light completely as a transported HGUT process, including propagation, polarization, energy and momentum flow, interference, emission, absorption, and quantized exchange.
Matter and Particle Closure
Classify the stable and transient products permitted by Harrison-Knot topology and Great Collision debris, then recover the observed particle, interaction, mass, and decay spectrum.
The Question Remains Open
Successful arguments, failed attempts, independent simulations, corrections, and falsifying evidence all move the research program forward.
