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.
The Problem
HGUT cosmology begins with a Great Collision involving pre-existing large-scale structures or phases. The open problem is to construct the dynamical model and map the outcome across impact parameter, velocity, angular momentum, material state, topology, and coupling values. Rebound, merger, partial merger, penetration, fragmentation, and asymmetric outcomes must be tested rather than assumed.
Scientific Importance
The collision outcome determines the origin of the Graviton Mesh, the initial conditions of cosmology, the particle-debris spectrum, large-scale asymmetry, and the interpretation of the cosmic microwave background.
Progress Ledger
The Great Collision is the organizing event of the current cosmological narrative.
Rebound, merger, and partial-merger interpretations have all been recognized as live possibilities.
The event has not yet been modeled with a completed field theory and systematic parameter scan.
Pass-or-Fail Structure
Every gate must be addressed before this problem can be considered closed. Partial success does not establish the complete identification.
Define the pre-collision objects, phases, fields, and boundary conditions.
Evolve the nonlinear event with conserved energy, momentum, angular momentum, and topology.
Map rebound, merger, partial merger, penetration, and fragmentation regimes.
Show how the organized Graviton Mesh emerges from the event.
Determine which stable and transient Harrison-Knot species are produced.
Extract expansion, contraction, density, temperature, perturbation, and asymmetry data.
Definition of Success
This problem closes only when the following conditions are satisfied together.
The pre-collision configuration is mathematically well defined.
The nonlinear collision is simulated with convergent conservation diagnostics.
The outcome regime is mapped across physically meaningful parameters.
Mesh formation and collision debris emerge dynamically.
The resulting state supplies consistent cosmological initial conditions.
The model distinguishes among rebound, merger, and partial-merger histories.
Predicted relics can be compared with CMB and large-scale-structure data.
Prerequisites
Open Collaboration
Connected Research
Cosmology
Derive the cosmic microwave background spectrum, anisotropies, polarization, acoustic structure, and large-scale anomalies from Great Collision initial conditions.
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.
Foundations of Time
HGUT has achieved foundational closure on the ontology of time: Sea Time is normalized substrate phase accumulation, Lab Time is the operational time accumulated by coherent structures, and the two are connected by the clock functional. The remaining work is derivational, dynamical, and empirical.
The Question Remains Open
Successful arguments, failed attempts, independent simulations, corrections, and falsifying evidence all move the research program forward.
