Understanding Early Universe Cosmology

The study of Big Bang theory provides a foundation for understanding the origins of our universe. According to this theory, the universe began as an extremely hot and dense point approximately 13.8 billion years ago, and has been expanding ever since.

One of the pivotal concepts in cosmic inflation explains the rapid exponential expansion of space in the very first moments after the Big Bang. This theory helps resolve several important issues, such as the horizon and flatness problems, offering a more comprehensive picture of the universe's earliest moments.

As the universe expanded and cooled, particles combined to form protons, neutrons, and eventually atoms. This process led to the formation of the first stars and galaxies. Detailed observations of the Cosmic Microwave Background (CMB) radiation provide a snapshot of the universe when it was just 380,000 years old, offering critical insights into its composition and evolution.

Understanding the large-scale structure of the universe helps cosmologists refine models of its early phases. Modern research continues to explore dark matter and dark energy, which make up most of the universe's content but remain poorly understood. These topics are central to ongoing efforts to comprehend our universe's ultimate fate.
