Description
The Friedmann-Lemaître-Robertson-Walker (FLRW) model, a cornerstone of the Lambda Cold Dark Matter (ΛCDM) framework, has long provided a robust explanation for the formation and evolution of cosmic structures, aligning with much of the observational data. At its core lies the cosmological principle, which posits that the universe is homogeneous and isotropic on large scales. However, recent three-dimensional catalogs present a different picture, revealing a universe that appears non-homogeneous and non-isotropic even at the farthest observational distances. This challenges the FLRW model's accuracy and suggests a need for its reassessment.
In this study, we derive new redshift-light intensity and redshift-number density relations using the Einstein Field Equations (EFE), employing the galaxy number count method to explore the universe's dynamics and evolution within the FLRW framework. Our findings show that these new relations effectively describe galaxy formation and evolution, enriching our understanding of the cosmos. Notably, they replicate the early burst of galaxy formation, which is consistent with other models. However, at higher redshifts, our results indicate a slower rate of structure formation and distribution, contrasting with predictions from alternative models. Furthermore, our simulation results align with observational data, supporting the FLRW model. These relations also open promising avenues for future cosmological research.
