The universe is vast and mysterious, presenting mankind with limitless possibilities for exploration. To truly become a great civilization, we must unravel the mysteries that lie within the universe.

Science is our most powerful tool in this endeavor, allowing us to venture beyond the confines of Earth and gain a preliminary understanding of the cosmos.

However, studying the vastness of the universe is not a haphazard endeavor devoid of rules and regulations. It requires a systematic approach. While the universe may seem boundless, the fundamental units that comprise it are not as vast as we might imagine. For instance, galaxies like our well-known Milky Way are composed of hundreds of billions of star systems, one of which is our solar system.

From the perspective of our solar system, it may appear expansive, but in comparison to the Milky Way, it is minuscule, spanning only about a light year in diameter. In contrast, the Milky Way stretches over 100,000 light years and contains an estimated 100-400 billion stars.

The stars we observe in the night sky on Earth mostly originate from deep within the Milky Way, with the closest one situated approximately 4.2 light years away. While the Milky Way may seem immense from our viewpoint, it is merely a speck in the vast cosmic expanse, serving as a basic unit of the universe.

The number of galaxies resembling the Milky Way in the entire universe remains a question mark for scientists. Due to the limitations of human observation and the fact that the universe is expanding at a rate faster than the speed of light at a distance of 13.7 billion light years, we are confined to the realm of an observable universe.

Within this observable range, scientists estimate the presence of trillions of galaxies akin to the Milky Way. To unravel the mysteries of the universe, we must first delve into the enigmas surrounding these galaxies, which constitute the fundamental building blocks of the cosmos. By deciphering the formation process of galaxies, we can progress toward uncovering the ultimate mysteries of the universe.

According to the Big Bang theory, the universe originated approximately 13.8 billion years ago with a singularity explosion. Following its birth, the universe underwent rapid expansion, eventually stabilizing after a period of chaos. Interstellar dust, gas clouds, dark matter, and stars coalesced to form massive galaxies.

Newly formed galaxies underwent a phase of instability and required collisions and mergers to attain stability. Similarly, our solar system emerged from a solar nebula and underwent a turbulent phase characterized by constant collisions and mergers. After hundreds of millions of years of evolution, it eventually settled into its current state, featuring eight planets. Through further exploration of distant galaxies, scientists anticipate uncovering truths about the early days of the universe. It is crucial to enhance our observational capabilities, hoping to discover even earlier galaxies and detect more nascent systems.

By expanding our knowledge, we can strive towards developing a comprehensive theory of the early universe and begin to unravel its vast complexities. The universe is an iceberg waiting to be explored, and with continued scientific progress, we inch closer to uncovering its concealed wonders.
