Observational study demonstrates a new framework for connecting effective dynamics with cosmological observables, suggesting novel implications.
Key Points
The aim is to reformulate the connection between internal effective dynamics and cosmological observables, addressing previous observational challenges.
Introduced a hierarchical framework distinguishing between demonstrated results, modeled relations, and open derivations.
Established a connection between logarithmic evolution of horizon entropy and observable cosmological infrared flow in spatially flat FLRW spacetimes.
Analyzed closed-form relationships through mathematical proofs on internal trajectories and observational closure.
Demonstrated a continuous strictly monotonic internal trajectory can be observationally equivalent to any arbitrary target history.
Proven that finite-order local differential closures reduce to effective algebraic closures, revealing observational degeneracy as a key issue.
Identified unrestricted closure freedom as the main source of observational non-identifiability.
