This thesis explores the "tropic evolution of the universe", or "spontaneous macro-structure configuration", as an emergent framework for understanding cosmic expansion. It highlights the interplay between gravitational boundary conditions, isotropy, and the intricate geometry of space-time. By considering how fundamental constants guide the self-organizing nature of the universe, this approach provides a novel perspective on the evolution of large-scale cosmic structures and the conditions necessary for their formation. Beginning with the study of the Cosmic Microwave Background (CMB) data from the WMAP satellite, this work addresses the critical implications of gravitationally induced anisotropies and their role in shaping the universe’s expansion. The analysis reveals how gravitational perturbations influence the geometry of the universe at its most primordial stages, from the earliest moments of the Big Bang to the present. Central to this work is the examination of the Cosmological Standard Model and the ΛCDM Model, with an emphasis on the concept of isotropy in the evolution of the universe. 

The framework presented here proposes a novel interpretation of cosmic isotropy, where the universe is perceived as evolving under the influence of tropic evolutionary dynamics. This model integrates advanced astrometry and gravitational boundary conditions to define the time horizon and the geometrical evolution of space-time, in particular the role of gravitational wells and anisotropic perturbations. The research investigates the time horizon of the universe, outlining how gravitational forces acting within space-time affect both the fabric of the cosmos and the ΛCDM parameters, including the Hubble constant (H₀), the cosmological constant (Λ), and the evolution of cosmic redshift. Through the use of Schwarzschild and Kerr metrics, the study derives equations that encapsulate relativistic shifts induced by high-gravity environments, demonstrating how these influence the cosmic expansion rate and the formation of large-scale structures, such as the first galaxies and stars. 

The Tropic Model also introduces a novel view of cosmic self-organization within chaotic gravitational events, where the universe’s evolution unfolds through emergent, gravity-driven mechanisms that alter initial boundary conditions. This interpretation highlights the entropic and anthropic dimensions of the universe's evolution, yet extends them to a tropic paradigm where the universe actively shapes itself through gravitational interactions, affecting its spatial and temporal configuration. In terms of gravitational boundary conditions, the study offers new insights into the anisotropies seen in CMB data, correlating them with the cosmic expansion rate and gravitational lensing effects. These findings contribute to the understanding of the dark energy problem, emphasizing the crucial role of gravitational influences in defining the observable universe.

The study further explores the gravitational dynamics involved in the formation of early structures, showing how these mechanisms influenced the emergence of the universe's first stars and galaxies. This work offers a conceptual redefinition of cosmological evolution, positing that the universe’s expansion is not merely a result of cosmic inflation but is driven by tropic principles that govern its spatial and temporal evolution. Future studies should delve into the implications of this model on cosmic horizon boundaries and its effects on multi-body gravitational interactions in larger cosmological systems.

Additionally, this work sets a precedent for complex inquiries, such as:

1. An inquiry into how boundary conditions, isotropy, and fundamental constants guide the self-organizing nature of the universe, leading to spontaneous macro-structure configuration.

2. An important argument about the models used to describe the universe through well-estabished laws, precise measurement criteria, and well defined mathematics, as well as the most reliable justifications we employ for the universes's most definitive characteristics, such as the cosmological principle, the anthropic principle, isotropy, and entropy.      

3. A question regarding how the initial conditions and the chaos contributed to the emergence of fundamental physical constants, enabling the existence of stars, galaxies, planets, and eventually, living beings.
