This repository includes mathematica codes for reproducing and cross-checking the results from sterile neutrino dark matter pioneered papers. Also it includes codes for freeze out and freeze in processes using toy models.Along with this, there are codes for leptogenesis process using neutrinos in early universe.

Paper 13: The Temporal Equivalence Principle - A Unified Resolution to the JWST High-Redshift Anomalies
This essay presents a clear and intuitive overview of the full Siamese Universe framework. It explains how a shared quantum vacuum, a minimal phase desynchronization, and CPT symmetry together generate matter, structure, and cosmic complexity. A causal narrative linking physical principles and observable signatures.
This work introduces the concept of Latent Structural Causality, a framework for describing physical entities that are formally present yet lack observable effects in certain regimes. Applied to cosmology, it interprets the emergence of gravity, light, and time as transitions of operativity rather than creations ex nihilo.
🌌 Explore latent structural causality to redefine physical existence in unobservable regimes and deepen understanding of cosmology and physics foundations.
