Abstract

This paper examines the evolutionary path of the universe from the period of cosmic inflation to the large-scale structures formation, such as clusters and galaxies. The inflationary model, which proposes a rapid exponential expansion shortly after the Big Bang, is explored in detail to explain the uniformity of the Cosmic Microwave Background (CMB) and the large-scale isotropy observed today. Key phases, such as the Recombination Era and Structure Formation, are analyzed, highlighting the role of dark matter in the gravitational collapse of baryonic matter and the formation of cosmic structures. The findings confirm that inflation is a crucial framework for understanding the universe’s large-scale properties, although challenges remain in explaining early galaxy formation and the nature of dark energy. Observational evidence from missions like WMAP and Planck provides strong support for the inflationary model, yet new discoveries from the James Webb Space Telescope prompt a reconsideration of early cosmic evolution models.
